OVER-THE-WIRE INTERLOCK ATTACHMENT/DETACHMENT MECHANISM

摘要

The over-the-wire interlock attachment/detachment mechanism includes a cylindrical lock receiving section (16) of a small attached to an implantable medical device (20) such as a blood clot filter, a stent, or a septal occluder. This cylindrical lock receiving section (16) has a plurality of spaced, curved cutouts (40) to receive both the guide fingers (26) and contoured locking fingers (34) formed on a cylindrical locking section (14). The locking fingers (34) are angled outwardly from the cylindrical body (22) of the cylindrical locking section (14), and are moved inwardly into engagement with the curved cutouts (40) of the cylindrical lock receiving section (16) by a sheath (18) which slides over the cylindrical locking section (14) or other suitable operator.
