Abstract
Abstract Abstract of the Disclosure Multipolar pacing conductor of drawn brazed strand wires of MP35N alloy in a silver matrix coiled around a diameter D and wires taken off at predetermined spatial locations. MP35N alloy is 35% nickel, 35% co-balt, 20% chromium and 10% molybdenum. The wires of the multipolar pacing conductor are insulated with a suitable insulation and handle separate currants for each wire or group of wires. A multipolar, multifilar pacing conduc-tor includes two or more wires wound in parallel on the coil.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
35 words
Multipolar pacing conductor comprising: at least two drawn brazed strand wires wound circumferentially in a coil, said at least two drawn brazed strand wires insulated from one another, providing two or more separate current paths.
Claim 2
Dependent Claim
35 words
Multipolar pacing conductor comprising: at least two drawn brazed strand wires wound circumferentially in a coil, said at least two drawn brazed strand wires insulated from one another, providing two or more separate current paths.
Claim 3
Dependent Claim
48 words
Multipolar pacing conductor comprising: at least two drawn brazed strand wires wound circumferentially in a coil wherein each wire takes off at a spatial predetermined location along a longitudinal axis of said coil for electrical connection to an electrode and a conductor at opposite ends of said wire.
Claim 4
Dependent Claim
48 words
Multipolar pacing conductor comprising: at least two drawn brazed strand wires wound circumferentially in a coil wherein each wire takes off at a spatial predetermined location along a longitudinal axis of said coil for electrical connection to an electrode and a conductor at opposite ends of said wire.
Claim 5
Dependent Claim
62 words
Multipolar, multifilar pacing conductor comprising: a. plurality of insulated and uninsulated wires wound on a diameter D along a longitudinal length, each of said wires taken off at spatial predetermined locations along the longitudinal axis of said coil; and b. at least one of said wires being uninsulated whereby said insulated wires handle separate currents and said uninsulated wire handles equal currents.
Claim 6
Dependent Claim
