Abstract
A method for electrically attaching electrode wire to a conductor in a defibrillation lead is disclosed. The method comprises melting the end of the wire with a hydrogen torch to form a ball of metal, then crimping or welding the ball to the conductor or to a joining piece attached to the conductor. Also, a hydrogen torch (water welder) may be used to join two or more electrode wires to each other.
Claims4
An electrical connection comprising:
- one end of each of a plurality of coiled platinum iridium wires melted to form a ball of metal such that each of said coiled platinum iridium wires is attached to said ball, said ball crimped within or welded to a metal sleeve, and said sleeve electrically attached to a conductor.
An electrical connection produced by the steps of:
- melting one end of each of a plurality of coiled platinum iridium wires to form a ball of metal such that each of said coiled platinum iridium wires is attached to said ball;
- crimping or welding said ball to a metal sleeve;
- and
- electrically attaching said metal sleeve to a conductor.
