Abstract
Disclosed is a cardiac pacing lead comprising an electrical stimulating member (electrode) with a plurality of biodegradable fins adjacent to its tip and with or without a porous metal coating. After surgical introduction, temporary fixation of the device to the surface of the cardiac wall is supplied by the fins. The device achieves permanent fixation by ingrowth of viable tissue into the interstices of the porous electrode and/or by tissue ensheathment of the distal portion of the lead. The process of permanent fixation occurs over a period of weeks during which time the fins are gradually absorbed into the blood and/or adjacent tissue. The lead can also be used to stimulate tissue other than cardiac tissue, such as nervous system tissue.
