Description

ABSTRACT:
A fitting which serves to connect the bare proximal end of the conductor in an implanted or implantable lead with a cardiac pacemaker has a deformable tubular socket with a proximal end insertable into a pacemaker and a distal end received in the proximal end of an insulating sleeve the distal end of which contains the tubular liner of an extractible guide serving to facilitate insertion of proximal end of the insulating tube for the conductor. The bare proximal end of the conductor is first slipped onto the tip of a stylet which extends through the axial passage of the socket as well as through the axial hole of the sleeve, and the proximal end of the conductor is then introduced into and through the sleeve and the socket until the front end face of the proximal end of the insulating tube strikes an internal shoulder of the sleeve. The proximal end of the socket is then deformed against the adjacent portion of confined proximal end of the conductor by screws which are mounted in a holder separably surrounding the proximal end of the socket. The stylet props the proximal end of the conductor from within during deformation of the socket. The stylet is then extracted and the holder is detached from the socket.
