Medtronic Inc. said Monday it received permission from the Food and Drug Administration to go ahead with a clinical trial to test the safety of its next generation MRI-compatible pacemaker.
The Advisa DR MRI SureScan, available in Europe since last year, is the follow-up to the Revo MRI SureScan, which got FDA approval in February
, becoming the first pacemaker conditionally cleared for use around MRI scanners.
The prospective, randomized, trial will enroll 270 patients worldwide, and is expected to wrap up by May 2013, according to the study's Clinical Trials page. It will not be blinded.
For those who need to move fast and expand clinical capabilities -- and would love new equipment -- the uCT 550 Advance offers a new fully configured 80-slice CT in up to 2 weeks with routine maintenance and parts and Software Upgrades for Life™ included.
The goal of the trial will be to determine the safety and effectiveness of the device, and to see whether it affects the quality of the MRI image.
Dr. Edward J. Schloss, who implanted the first Advisa in a U.S. patient as part of the clinical trial at The Christ Hospital in Cincinnati, called the trial "an important milestone" for heart patients needing MRI scans.
Fridley-based Medtronic estimates 50-75 percent of patients with pacemakers will need an MRI at some point in their lives.
