Manufacturers are finding it harder to innovate in the vascular interventional devices as market and regulatory pressures take their toll. New coronary drug-eluting stents face a difficult challenge with the high bar now set by existing devices, and there have been several recent disappointments in renal denervation, drug-coated balloons, and renal artery stenting; still there are some promising areas, with bioresorbable stents offering perhaps the best prospect among vascular therapies for future blockbuster status.

Biotronik also announced that it has moved into the second phase of an MRI-compatibility trial of its Entovis pacemaker. More research news.
