XIENCE V
®
and Magnetic Resonance Imaging Examination

©2011 Abbott
To Whom it May Concern:
Thank you for your inquiry regarding magnetic resonance imaging (MRI) examinations of patients implanted
with the Abbott Vascular XIENCE V
®
and XIENCE nano
TM
Everolimus Eluting Coronary Stent (hereafter
referred to as XIENCE V
®
stent). The XIENCE V
®
Everolimus Eluting Coronary Stent is a device/drug
combination product consisting of either the MULTI-LINK VISION
®
Coronary Stent or the MULTI-LINK
MINI VISION
®
Coronary Stent coated with a formulation containing everolimus, the active ingredient,
embedded in a non-erodible polymer. The MULTI-LINK VISION
®
stents are manufactured from medical
grade L-605 cobalt chromium (CoCr) alloy.
The following post implant precaution statement is included in the Instructions for Use of the XIENCE V
®
Everolimus Eluting Coronary Stent System:
“Non-clinical testing has demonstrated that the XIENCE V
®
stent, in single and in overlapped
configurations up to 68 mm in length, is MR Conditional. It can be scanned safely under the following
conditions:
Static magnetic field of 1.5 or 3 Tesla
Spatial gradient field of 2500 Gauss/cm or less
Maximum whole-body-averaged specific absorption rate (SAR) of 2.0 W/kg (normal operating
mode) for each duration of a sequence
The XIENCE V
®
stent should not migrate in this MRI environment. Non-clinical testing at field
strengths greater than 3 Tesla has not been performed to evaluate stent migration or heating. MRI at 1.5
or 3 Tesla may be performed immediately following the implantation of the XIENCE V
®
stent.
Stent heating was derived by using the measured non-clinical, in vitro temperature rises in a GE Excite 3
Tesla scanner and in a GE 1.5 Tesla coil in combination with the local specific absorption rates (SARs)
in a digitized human heart model. The temperature rise was derived by validated calculation. At
overlapped lengths up to 68 mm, the XIENCE V
®
stent produced a non-clinical maximum local
temperature rise of 3ºC at a maximum whole body averaged SAR of 2.0 W/kg (normal operating mode)
for one sequence of 15 minutes. These calculations do not take into consideration the cooling effects of
blood flow.
The effects of MRI on overlapped stents greater than 68 mm in length or stents with fractured struts are
unknown.
As demonstrated in non-clinical testing, an image artifact can be present when scanning the XIENCE V
®
stent. MR image quality may be compromised if the area of interest is in the exact same area, or
relatively close to, the position of the XIENCE V
®
stent. Therefore, it may be necessary to optimize the
MR imaging parameters for the presence of XIENCE V
®
stents.”

Everolimus Eluting Coronary Stent on the MULTI-LINK VISION
®
or MULTI-LINK
MINI VISION
®
Delivery System
INDICATIONS
The XIENCE V Everolimus Eluting Coronary Stent System (XIENCE V stent) is indicated for improving coronary luminal diameter in patients with
symptomatic heart disease due to de novo native coronary artery lesions (length 28 mm) with reference vessel diameters of 2.25 mm to 4.25 mm.
CONTRAINDICATIONS
The XIENCE V stent is contraindicated for use in patients:
Who cannot receive antiplatelet and/or anti-coagulant therapy
With lesions that prevent complete angioplasty balloon inflation or proper placement of the stent or stent delivery system
With hypersensitivity or contraindication to everolimus or structurally-related compounds, cobalt, chromium, nickel, tungsten, acrylic-polymers or
fluoropolymers.
WARNINGS
Ensure that the inner package sterile barrier has not been opened or damaged prior to use.
Judicious patient selection is necessary because device use has been associated with stent thrombosis, vascular complications, and/or bleeding
events.
This product should not be used in patients who are not likely to comply with the recommended antiplatelet therapy.
PRECAUTIONS
Stent implantation should only be performed by physicians who have received appropriate training.
Stent placement should be performed at hospitals where emergency coronary artery bypass graft surgery is accessible.
Subsequent restenosis may require repeat dilatation of the arterial segment containing the stent. Long-term outcomes following repeat dilatation of the
stent are presently unknown.
Risks and benefits should be considered in patients with severe contrast agent allergies.
Care should be taken to control the guiding catheter tip during stent delivery, deployment and balloon withdrawal. Use fluoroscopy to avoid arterial
damage.
Stent thrombosis is a low-frequency event that is frequently associated with myocardial infarction (MI) or death.
When DES are used outside the specified Indications for Use, patient outcomes may differ from the results observed in the XIENCE V SPIRIT family
of trials.
Compared to use within the specified Indications for Use, the use of DES in patients and lesions outside of the labeled indications may have an
increased risk of adverse events, including stent thrombosis, stent embolization, MI, or death.
Orally administered everolimus combined with cyclosporine is associated with increased serum cholesterol and triglycerides levels.
A patients exposure to drug and polymer is proportional to the number of and total length of implanted stents. See Instructions for Use for current
data on multiple stent implantation.
Safety and effectiveness of the XIENCE V stent have not been established for subject populations with the following clinical settings:
Patients with prior target lesion or in-stent restenosis related brachytherapy, patients in whom mechanical atherectomy devices or laser angioplasty
devices are used simultaneously, women who are pregnant or lactating, men intending to father children, pediatric patients, unresolved vessel
thrombus at the lesion site, coronary artery reference vessel diameters < 2.25 mm or > 4.25 mm or lesion length > 28 mm, lesions located in
saphenous vein grafts, unprotected left main coronary artery, ostial lesions, chronic total occlusions, lesions located at a bifurcation or previously
stented lesions, diffuse disease or poor flow (TIMI < 1) distal to the identified lesions, excessive tortuosity proximal to or within the lesion, recent
acute myocardial infarction (AMI) or evidence of thrombus in target vessel, moderate or severe lesion calcification, multivessel disease, and in-stent
restenosis
Everolimus has been shown to reduce the clearance of some prescription medications when it was administered orally along with cyclosporine (CsA).
Formal drug interaction studies have not been performed with the XIENCE V stent because of limited systemic exposure to everolimus eluted from
XIENCE V.
Everolimus is an immunosuppressive agent. Consideration should be given to patients taking other immunosuppressive agents or who are at risk for
immune suppression.
Oral everolimus use in renal transplant patients and in patients treated for advanced renal cell carcinoma was associated with increased serum
cholesterol and triglycerides that in some cases required treatment.
Non-clinical testing has demonstrated that the XIENCE V stent, in single and in overlapped configurations up to 68 mm in length, is MR Conditional. It
can be scanned safely under the conditions in the Instructions for Use.
The XIENCE V stent should be handled, placed, implanted, and removed according to the Instructions for Use.

MULTI-LINK MINI VISION
®
Coronary Stent System
INDICATIONS
The MULTI-LINK MINI VISION RX and MULTI-LINK MINI VISION OTW Coronary Stent Systems are indicated for improving
coronary luminal diameter in patients with abrupt or threatened abrupt closure
with failed interventional therapy of de novo and restenotic
native coronary artery lesions (
length
25 mm)
with reference vessel diameters from 2.0 mm to 2.5 mm.
CONTRAINDICATIONS
The MULTI-LINK MINI VISION Coronary Stent Systems are contraindicated for use in:
• Patients in whom anti-platelet and / or anti-coagulant therapy is contraindicated.
• Patients judged to have a lesion that prevents complete inflation of an angioplasty balloon.
WARNINGS AND PRECAUTIONS
WARNINGS
Long term outcome for this permanent implant is unknown at present.
• Judicious selection of patients is necessary since the use of this device carries the associated risk of subacute thrombosis, vascular
complications and / or bleeding events.
• Persons allergic to L-605 CoCr alloy (including the major elements cobalt, chromium, tungsten, nickel) may suffer an allergic reaction
to this implant.
• Implantation of the stent should be performed only by physicians who have received appropriate training.
• Stent placement should only be performed at hospitals where emergency coronary artery bypass graft surgery can be readily performed.
• Subsequent restenosis may require repeat dilatation of the arterial segment containing the stent. The long-term outcome following repeat
dilatation of endothelialized stents is unknown at present.
• When multiple stents are required, stent materials should be of similar composition. Placing multiple stents of different metals in contact
with each other may increase the potential for corrosion. The risk of in vivo corrosion does not appear to increase based on in vitro
corrosion tests using an L-605 CoCr alloy stent (MULTI-LINK VISION
®
Coronary Stent) in combination with a 316L stainless steel alloy
stent (MULTI-LINK TETRA Coronary Stent).
Stent Handling – Precautions
For single use only
. Do not resterilize or reuse. Note the product “Use By” date.
Do not remove stent from its delivery system
as removal may damage the stent and / or lead to stent embolization. Stent system is
intended to perform together as a system.
• Delivery system should not be used in conjunction with other stents.
• Special care must be taken not to handle or in any way disrupt the stent on the balloon. This is most important during catheter removal
from packaging, placement over guide wire and advancement through rotating hemostatic valve adapter and guiding catheter hub.
• Do not manipulate (e.g., “roll”) the stent with your fingers, as this action may loosen the stent from the delivery balloon.
• Use only the recommended balloon inflation medium. Never use air or any gaseous medium to inflate the balloon, as this may cause
uneven expansion and difficulty in deployment of the stent.
Stent Placement – Precautions
Do not prepare or pre-inflate delivery system prior to stent deployment
other than as directed. Use balloon purging technique
described in
Delivery System Preparation
.
• Implanting a stent may lead to dissection of the vessel distal and / or proximal to the stent and may cause acute closure of the vessel
requiring additional intervention (CABG, further dilatation, placement of additional stents, or other).
AP2934652 Rev. A 05/11
©2011 Abbott
• When treating multiple lesions, stent the distal lesion prior to stenting the proximal lesion. Stenting in this order obviates the need to
cross the proximal stent in placement of the distal stent, and reduces the chance of dislodging the proximal stent.
• Do not expand the stent if it is not properly positioned in the vessel.
(See Stent / System Removal – Precautions)
• Placement of a stent has the potential to compromise side branch patency.
Do not exceed the Rated Burst Pressure as indicated on the product label.
Monitor balloon pressures during inflation. Use of
pressures higher than specified on product label may result in a ruptured balloon with possible intimal damage and dissection.
• An unexpanded stent may be retracted into the guiding catheter one time only. Subsequent movement in and out through the distal end
of the guiding catheter should not be performed as the stent may be damaged when retracting the undeployed stent back into the guiding
catheter. Should
any resistance
be felt
at any time
during withdrawal of the Coronary Stent System, the entire system should be
removed as a single unit
.
• Stent retrieval methods (use of additional wires, snares and / or forceps) may result in additional trauma to the coronary vasculature and
/ or the vascular access site. Complications may include bleeding, hematoma or pseudoaneurysm.
Stent / System Removal – Precautions
Should
any resistance
be felt
at any time
during either lesion access or removal of the delivery system post-stent implantation, the entire
system should be
removed as a single unit
.
When removing the delivery system as a single unit:
• DO NOT retract the delivery system into the guiding catheter.
• Position the proximal balloon marker just distal to the tip of the guiding catheter.
• Advance the guide wire into the coronary anatomy as far distally as safely possible.
• Tighten the rotating hemostatic valve to secure the delivery system to the guiding catheter; then remove the guiding catheter and
delivery system as a
single unit
.
Failure to follow these steps and / or applying excessive force to the delivery system can potentially result in loss or damage to the stent
and / or delivery system components.
If it is necessary to retain guide wire position for subsequent artery / lesion access, leave the guide wire in place and remove all other
system components.
Post Implant – Precautions
When
crossing a newly deployed stent
with a guide wire, balloon or delivery system, exercise care to avoid disrupting the stent
geometry.
MRI (Magnetic Resonance Imaging) statement
The MULTI-LINK MINI VISION stent has been shown in non-clinical testing to be MRI safe immediately following implantation.
MRI
test conditions used to evaluate this stent were: for magnetic field interactions, a static magnetic field strength of 3 tesla
with a
maximum spatial gradient magnetic field of 3.3 tesla/meter; for MRI-related heating, a maximum whole body averaged specific
absorption rate (SAR) of 2.0 W/kg for 15 minutes of MR imaging
. While a single stent produced a temperature rise of less than 0.6°C
and should not migrate under these conditions, the response of overlapping stents or stents with fractured struts is unknown. Non-clinical
testing has not been performed to rule out the possibility of stent migration at field strengths higher than 3 tesla. MR image quality may
be compromised if the area of interest is in the exact same area or relatively close to the position of the stent.
POTENTIAL ADVERSE EVENTS
Adverse events may be associated with the use of a coronary stent in native coronary arteries:
• Acute myocardial infarction • Allergic reaction to contrast • Arterial perforation • Arterial rupture • Arteriovenous fistula • Cardiac
arrhythmias • Bleeding complications (including transfusions) • Coronary spasm • Death • Dissection of the coronary artery • Drug
reaction to anti-platelet agent • Emergency or non-emergent coronary artery bypass graft surgery • Entry site complications • Hypotension
/ hypertension • Infection • Injury to the coronary artery • Ischemia • Pseudoaneurysm • Restenosis of the stented segment • Stent
embolization • Stent thrombosis / emboli • Stroke / cerebrovascular accident • Total occlusion of the coronary artery • Unstable angina
pectoris • Vascular complications
