Lead implantable in the coronary veins for stimulating a left cavity of the heart

摘要

The end (34) of the probe auto-orientates, and the electrode is of a sector type with a lateral part extending in a radial plane only within one sector of the probe. Device comprises a probe body with an elastically deformable hollow casing, the end (34) of which holds a stimulation electrode (54). A detachable mandrel can be introduced into the hollow body and moved within the hollow tube with the mandrel relatively rigid compared with hollow tube. It is also locally plastically deformable. The end (34) of the probe naturally forms two distinct curves that are formed on each of its surfaces. A first surface (62) corresponds to one orientation curve, and a second surface (64) corresponds to a pressure surface.
