Abstract
An electrode assembly for use with a catheter, is made of a plurality of insulated wires. The wires are bound together in a bundle by fine insulated wire for almost their entire lengths. At one end of the bundle are free wire ends of different lengths on which are electrically conductive ferrules. The ferrules are spaced apart axially when aligned with the bundle inside the catheter. The wires are made of springy material so that the free wire ends separate widely outside the catheter. Other cylindrical ferrules are mounted in axially spaced position on bared portions of the other end of the bundle, and encircle all the wires, but each ferrule is in direct electrical contact with only one of the wires.
Claims10
An electrode assembly for insertion into a catheter and establishing an electrical connection to an electronic circuit, said assembly comprising:
- a plurality of wires, each of said wires insulated from each other and each of said wires being electrically conductive and extending together side-by-side and having different lengths at one end thereof;
- an insulated other wire binding said plurality of wires together for substantially their entire length except for a free end at said one end of each of said wires;
- an end portion of each of said free ends being bared of insulation;
- an electrically conductive ferrule positioned on each of said bared portions on each of said free ends of said wires, said ferrules being spaced apart axially of each other when axially aligned with said free ends of said wires inside said catheter;
- and
- a conductive means for connecting the other ends of each of said wires to said electronic circuit.
