Maker Halts Sale of Heart Implant Part Following 5 Deaths
WASHINGTON — Medtronic Inc. has suspended distribution of its Sprint Fidelis defibrillation leads after identifying five patient deaths in which a lead fracture may have been a contributing factor.
A defibrillator monitors a patient's heartbeat; if it senses an abnormal heart rhythm, it delivers an electronic shock to reset the heart to a normal beat. A defibrillation system consists of a device implanted near the shoulder with one or more leads connecting the device to the heart.
Medtronic said Monday it had discovered a "small chance of fractures in particular locations" on Sprint Fidelis models 6930, 6931, 6948 and 6949. The company is asking doctors to stop implanting the leads and return all unused leads to Medtronic.
