The controversy over the use of paclitaxel-bearing devices in the femoropopliteal arteries is far from over. Now, a new medical journal article makes a similar claim about mortality in connection with the use of these devices in the infrapopliteal arteries, threatening once again to take a bite out of utilization. The first study to generate controversy over paclitaxel in drug-coated balloons and drug-eluting stents appeared in the medical literature toward the end of 2018, and a flurry of activity ensued.
Ra Medical Systems Inc., of Carlsbad, Calif., reported that the U.S. FDA has granted investigational device exemption (IDE) approval to study its DABRA excimer laser system as an atherectomy device to treat peripheral vascular stenosis.
Dublin-based Medtronic plc has snagged the U.S. FDA’s approval for its Micra AV, the world’s smallest pacemaker with atrioventricular (AV) synchrony. The company said it will begin rolling out the device at a limited number of medical centers in the upcoming weeks, with a full, nationwide launch sometime this spring. About the size of a large vitamin pill, the leadless Micra AV is indicated for the treatment of patients with AV block, a disorder that occurs when the electrical signal traveling from the atria, or upper chambers of the heart, to the ventricles, or lower chambers, is impaired.
A new report by the Congressional Research Service (CRS) revives the question of U.S. FDA regulation of lab-developed tests (LDTs). However, attorney Jeffrey Shapiro, of Washington-based Hyman Phelps & McNamara PC, told BioWorld that the agency is no longer in a position to unilaterally impose a regulatory regime on LDTs, and that there is little likelihood that any enabling legislation will pass until at least 2021.
The U.S. FDA has granted breakthrough device designation to Mojo Vision Inc. for its first-of-a-kind true smart contact lens. The Mojo Lens, which features “invisible computing” and a built-in display, enables people to get timely information without having to look away from what they are doing or glance at a screen.
Transenterix Inc., of Research Triangle Park, N.C., said Tuesday that it has filed a 510(k) submission with the U.S. FDA for the Intelligent Surgical Unit (ISU), a machine vision system designed to work with its robotic Senhance surgical system. The new technology would equip users of the Senhance system with augmented intelligence to improve performance and surgical outcomes.
Abbott Park, Ill.-based Abbott Laboratories has gained the U.S. FDA’s nod for a clinical trial that will compare the effectiveness of Mitraclip to open-heart mitral valve surgical repair in people with primary mitral regurgitation (MR) who are eligible for open-heart surgery. The prospective, randomized REPAIR MR clinical trial is expected to enroll 500 patients.
In the latest step toward making left ventricular assist devices (LVADs) easier and more accessible, the FDA recently approved a less invasive surgical approach for use with Abbott Laboratories’ latest LVAD, Heartmate 3. Now, rather than requiring risky open-heart surgery, the device can be implanted through an incision in the chest wall. Abbott gained Heartmate 3 in its 2017 acquisition of St. Jude Medical for $25 billion.
The U.S. has granted final approval to Microvention Inc., a subsidiary of Terumo Corp. based in Aliso Viejo, Calif., for its Flow Redirection Endoluminal Device (FRED) for the treatment of brain aneurysms. The flow diverter – Microvention’s third PMA approval in less than two years – is the first in the U.S. to utilize a self-expanding, braided nitinol mesh to aid in rerouting blood flow away from the weakened area and promote occlusion.
Jenavalve Technology Inc., of Irvine, Calif., has won an FDA breakthrough device designation for its namesake transcatheter aortic valve replacement device, but Jenavalve said it will file for a humanitarian device exemption in the second half of 2020, suggesting that the device won’t be commercially available for at least another year.
