Connector arrangement for a lead for an implantable stimulation device
First Claim
1. In an implantable stimulation device having an electrode lead with a proximal end and a terminal portion of said device having a socket in which said proximal end of said lead is received, the improvement being a connector arrangement comprising:
- means for fixing said proximal end of said lead in said socket to make a rigid mechanical and electrical connection, said means for fixing having a longitudinal axis; and
means in said terminal portion of said device for receiving said means for fixing such that the longitudinal axis thereof is tangential relative to said proximal end of said lead and substantially normal to the direction of insertion of said lead into said socket.

Abstract
A connector arrangement for a lead for an implantable stimulation device, such as a heart pacemaker, has a receptacle in which a proximal end of a lead is received and a fixing element which is disposed tangentially relative to the proximal end of the lead. The fixing element can assume a first position which provides enough clearance in the receptacle to permit insertion of the proximal end of the lead, and a second position wherein the fixing element forces the proximal end of the lead tightly against a portion of the wall of the receptacle, so that the proximal end is held tightly in the receptacle to make a reliable mechanical and electrical connection. The arrangement permits the housing of the stimulation device to have a small thickness dimension.

8. In an implantable stimulation device having an electrode lead with a proximal end and a terminal portion of said device having a socket in which said proximal end of said lead is received, the improvement being a connector arrangement comprising:
-
a deformable sleeve mounted in said terminal portion of said device tangentially to said proximal end of said lead in said socket, said sleeve initially having an underformed first position which does not interfere with insertion of said proximal end of said lead into said socket; and means for expanding said sleeve to a second position in contact with said proximal end of said lead in said socket to fix said proximal end of said lead in said socket so that said lead and said socket are in rigid mechanical and electrical connection. - View Dependent Claims (9)
