Quick summary
This Biotronik Corox OTW-L85-BP is an implanted lead that delivers drug-eluting therapy to the heart's left ventricle. The 73 reports mostly describe the lead not working as expected — the wire moving out of position, failing to pace the heart, needing unusually high energy to capture a beat, and one case where the lead fractured and a piece was left in the patient during removal. Reports also mention infections and unwanted nerve or muscle stimulation. There were 27 injuries and no deaths, and no recalls name this device.
