CABLE CONDUCTOR FITTING

摘要

Various embodiments concern a lead comprising a cable conductor and a coil electrode having one or more filars, the one or more filars wound in a helical pattern. The lead can further include an inner fitting axially aligned with the coil electrode. The inner fitting can comprise external threading and a slot extending along the inner fitting. The slot can receive a portion of the cable conductor. The lead can include an outer tubular fitting having a lumen with internal threading. Each of the coil electrode and the inner fitting can be partially received within the lumen, both of the external threading and the one or more filars threadedly engaged with the internal threading. The cable conductor can be pinched in the slot to mechanically connect the cable conductor to the inner fitting. The pinching can be supported by the outer tubular fitting.

主权项

1. A method for assembling an implantable lead, the method comprising:
placing a cable conductor within a slot of an inner fitting, the inner fitting comprising external threading that extends over at least a portion of the inner fitting; axially aligning a coil electrode with the inner fitting, the coil electrode having one or more filars, the one or more filars wound in a helical pattern; and inserting the coil electrode and the inner fitting into a lumen of an outer tubular sleeve, the lumen having internal threading, wherein one or more of the outer tubular fitting, the coil electrode, and the inner fitting are rotated during the insertion such that the internal threading threadably engages both of the one or more filars and the external threading, the cable conductor is pinched within the slot as the inner fitting is inserted into the lumen, and the pinching mechanically connects the cable conductor to the inner fitting.
