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.
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.
While the disappearing drug-eluting stent seems to have faded from view for the time being, several manufacturers have invested in fabrication of drug-eluting stents with polymers that absorb once the drug of elution has done its work. A new study indicates that patients who have already had a myocardial infarction fare better on stents made with these biodegradable polymers, an outcome that may soon push second-generation DES devices into med-tech history.
