Autonomous (leadless) intracardiac implantable medical device with releasable base and fastener element

摘要

A leadless autonomous intracardiac implantable medical device having a releasable fastener system. This autonomous intracorporeal active medical device has two distinct elements connectable together and reversibly separable from one another, with a sealed capsule body (100) housing electronic circuitry (110), and a base (200) comprising a plate (202) having an outer face and an anchoring system on said outer face to anchor the base to a wall of an organ of a patient, and an inner face forming a support for the capsule body and having a fastening system to couple releasably the capsule body to the base. The capsule body comprises on its face turned towards the base at least one projection support (108) on an electrode surface for coming into contact with the wall of the organ of the patient when the capsule body is mounted on the base.
