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 study of 30 patients has demonstrated that embolization coils adequately seal the left atrial appendage after implant of LAA closure devices, but the author of an accompanying editorial expressed concerns regarding the absence of understanding of both the causes and implications of these leaks.
Device makers only can watch when cardiologists grapple with federal agency officials over device utilization. However, cardiologists are punching back hard against a rule used to judge whether a coronary artery stent is appropriately used, thus ensuring these devices won’t suffer a significant drop in utilization.
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.
Artificial intelligence (AI) health care startup Cardiologs Technologies SAS scooped up $15 million in a series A funding round led by Alven Capital Partners. The Paris-based company, which has an artificial intelligence-based platform to quickly diagnose cardiac arrhythmias, plans to use the money to grow its sales and marketing efforts across North America and Europe. The funds will also be used to advance the platform’s capabilities. Also participating in the financing were previous investors Bpifrance, Isai, Kurma Diagnostics, Idinvest Partners and Paris Saclay Seed Fund.
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.
