FOLDABLE ANCHOR BARBON PROBES FOR AN IMPLANT MEDICAL DEVICE, IN PARTICULAR FOR A CARDIAC STIMULATOR

摘要

P This probe comprises a cylindrical body (10) carrying the electrode (12) and a removable sleeve (16) which caps it. BR/ The sleeve comprises a retaining ring (18) removably mounted on the body for allow the subsequent dissociation of the sleeve from the body by axial traction of the latter, and deformable means (24) extending from the retaining ring and capable of taking two stable configurations. The passage from the first to the second configuration results from an external bias exerted axially on the sleeve. The means essentially not projecting radially in the first configuration, so as to allow the introduction of the probe in place, and substantially projecting radially in the second configuration so as to form anchoring barbs. BR/ Advantageously , the anchoring barbs of the deformable means are interconnected by a movable element (22) surrounding the body and sliding along it between an initial position and a final position corresponding to the two stable configurations of the deformable means, which connect the retaining ring (18) and the movable element (22). / P
