Medical electrical lead having a reinforced tine assembly
First Claim
1. A medical electrical lead comprising:
- a connector assembly;
a coiled conductor having a distal end and a proximal end, the proximal end electrically coupled to the connector assembly;
an electrode electrically coupled to the distal end of the coiled conductor;
a insulative sheath covering the coiled conductor;
a tine assembly coupled to the insulative sheath at a first location spaced apart from the electrode, the tine assembly having a lumen, the tine assembly having at least one tine, the tine assembly having a cylindrical wall, the tine assembly having a longitudinal reinforcement member mounted within the cylindrical wall for preventing stretching or elongation of the tine assembly, the longitudinal reinforcement member is a cylinder member which encircles the lumen of the tine assembly, the longitudinal reinforcement member extending from a first point proximal relative to the first location, across the first location, to a second point distal relative to the first location.

Abstract
A medical lead which has a reinforced tine assembly. In particular, the medical electrical lead of the present invention features an elongated lead body covered by an insulative sheath. Positioned upon the proximal end of the lead body is a terminal assembly. Terminal assembly permits the lead to be connected to a pulse generator. Positioned at the distal end of the lead body is an electrode. Also positioned proximate the electrode is a tine assembly. The tine assembly is preferably made from a insulative bio-compatible material, preferably silicone. The tine assembly further features a reinforcement to prevent the tine assembly from elongating. In the preferred embodiment, a polyester is used to provide reinforcement member.
