Cardiac lead with reduced inner crimp sleeve
First Claim
1. A cardiac lead, comprising:
- a connector for coupling to a cardiac stimulator;
an inner crimp sleeve;
an outer crimp sleeve crimped around the inner crimp sleeve;
a first conductor wire electrically coupled to said connector having at least a first loop and a second loop; and
a second conductor wire having a third loop, the first and second conductor wires being spiraled together so that the third loop is positioned between the first and second loops at least one of said first and second loops and said third loop being crimped between the inner crimp sleeve and the outer crimp sleeve.

Abstract
A cardiac lead includes a connector for coupling to a cardiac stimulator and a flexible insulating sleeve having a first end coupled to the connector. An inner crimp sleeve is coupled to the insulating sleeve and an outer crimp sleeve crimped around the inner crimp sleeve. A first conductor wire is provided that has at least a first loop and a second loop. A second conductor wire is provided that has a third loop. The first and second conductor wires are spiraled together so that the third loop is positioned between the first and second loops and is crimped between the inner crimp sleeve and the outer crimp sleeve. The arrangement eases the passage of a stylet past the union of two wires, reducing the potential for stylet buckling. An aperture is provided in the outer crimp sleeve.
