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.
