Showcasing its leadership position in pacing
technologies, Medtronic, Inc. MDT, today announced the U.S. Food and
Drug Administration (FDA) approval and U.S. launch of its Advisa DR MRI(TM)
SureScan^® pacing system. The Advisa MRI system is Medtronic's
second-generation MR-Conditional pacemaker and is the first system to combine
the most advanced pacing technology with proven MRI access.
MRI is the standard of care in soft tissue imaging, providing information not
seen with X-ray, ultrasound or CT scans, and is critical for early detection,
diagnosis and treatment. Advisa MRI was specifically tested and approved for
use as labeled with MRI scanners in the U.S. Of the 156 patients scanned in
the Advisa MRI Clinical Trial, none showed any MRI-related complications. The
new system includes an Advisa MRI device and two CapSureFix MRI^(TM)
SureScan^® leads, which must be used together.
"Your physician can implant a pacemaker with advanced options that will allow
for broad access to MRI scanning," said Dr. J. Rod Gimbel of Cardiology
Associates of East Tennessee in Knoxville, Tenn. "MRI is just so very
important and traditional pacemakers not FDA approved for MRI scanning often
prevent the patient from having an MRI when they need it. With more than 85
percent of pacemaker patients being at least 65 years old and having multiple
comorbidities for which MRI may be needed, it's key that physicians and
patients have a pacing system that allows MRI imaging as a diagnostic
procedure."
The first SureScan pacemaker system was introduced in Europe in 2008 and its
use in the MRI environment is supported by clinical studies and extensive
computer modeling, as well as real-world data. To date, more than 100,000
Medtronic SureScan devices have been sold worldwide;^[1] and, in the U.S., it
is estimated that more than 10 percent of patients with SureScan pacing
systems have received MRIs.^[2] These patients received Medtronic's
first-generation Revo MRI^® SureScan^® pacing system, which was the only FDA
approved (February 2011) MR-Conditional pacemaker in the U.S. before the
Advisa MRI system.
Until the availability of Medtronic's SureScan pacing systems, patients with
pacemakers in the U.S. have been contraindicated from receiving MRI scans
because of potential interactions between the MRI and device function.
According to published literature, up to 75 percent of patients worldwide with
implanted cardiac devices are expected to need an MRI scan during the lifetime
of their devices.^[3]
Advisa MRI - Medtronic's MRI Pacing System with Innovative Technology
Medtronic's Advisa MRI pacing system provides physicians with innovative
technology that will benefit their patients, including the MVP^® (Managed
Ventricular Pacing) algorithm, which is proven to reduce unnecessary
ventricular pacing.^[4] Additional Advisa features include:
* Complete automaticity with Ventricular and Atrial Capture Management(TM)
(VCM and ACM) to eliminate manual threshold checks and extend longevity of
the device by up to one year.^[5]
* Diagnostics, such as the Cardiac Compass^® Report, and AF management tools
that assist physicians in the early detection and treatment of atrial
fibrillation.
* Remote monitoring via Medtronic's CareLink^® Network, which transmits
comprehensive arrhythmia and diagnostic device data to a physician's
clinic.
* Rate Drop Response that identifies abrupt cardiac slowing and responds by
pacing the heart at an elevated rate, which may reduce the frequency of
syncope (fainting) in patients with apparent cardio-inhibitory vasovagal
syncope.^[6]^, [7]
* Highupper tracking rate to provide pacing support at higher heart rates
for active and younger patients.
This system is the latest addition to a growing number of Medtronic devices
which are designed for MRI access including the SynchroMed^® II programmable
drug infusion system available worldwide, and the SureScan^® neurostimulation
systems for the management of chronic pain which are available in Europe. In
addition, SureScan^® pacing systems - including Advisa MRI - are available
worldwide.
In collaboration with leading clinicians, researchers and scientists
worldwide, Medtronic offers the broadest range of innovative medical
technology for the interventional and surgical treatment of cardiovascular
disease and cardiac arrhythmias. The company strives to offer products and
services that deliver clinical and economic value to healthcare consumers and
providers around the world.
