Pacemaker connector system
First Claim
Patent Images
1. A pacemaker connector system comprising:
- a connector block attached to a pacemaker, said connector block having a first aperture therein, said aperture defining a generally circular bore adapted to accept a pacemaker lead;
a retainer mating with said connector block and having a second aperture therethrough, also adapted to accept a pacemaker lead and being aligned with said first aperture in said connector block; and
a generally annular unclosed ring spring member with a projecting generally straight end portion extending about and partially obstructing said bore when in a relaxed state but capable of being expanded to a size larger than said pacemaker lead by the application of force to an end of said generally straight end portion.

Abstract
A pacemaker connector system for the coaxial heart lead of a bipolar pacemaker consists of two connector block assemblies housing circular springs which circumferentially grip the central and outer terminals of the lead. Protruding ends of the springs are covered by rubber septum buttons which, when depressed, open the spring interiors to allow insertion of the heart lead. The problems associated with set screw systems are eliminated, and improved mechanical and electrical contact over other types of spring systems is provided.

7. A pacemaker connector system comprising:
-
a generally sigma-shaped spring having an open ring annular portion and a generally straight extension for expanding the annular portion upon the application of a generally tangential force along said extension; a connector attached to a pacemaker, said connector block block enclosing and connected to said spring, the block defining a first aperture therein sized to receive a pacemaker lead electrode for coupling to said spring, the annular portion of the spring being smaller than said electrode but expandable within said block to admit said electrode; and a retainer having an aperture therethrough corresponding to said first aperture and aligned therewith for retaining the spring within said connector block. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A pacemaker connector system for coaxial bipolar leads comprising:
-
a first circumferentially spring-gripping connector block assembly attached to a pacemaker, said connector block assembly adapted for accepting and holding the distal end of a center lead; and a second circumferentially spring-gripping connector block assembly adapted for accepting and holding an outer lead concentric with said center lead and spaced apart from the distal end thereof, both of said assemblies having means for establishing spring-releasable electrical connections from said pacemaker to said leads. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
