Abstract: Disclosed herein is an implantable medical lead. In one embodiment, the lead includes a tubular body, a sensor module, and a distal crimp sleeve. The tubular body includes a distal end and a proximal end. The sensor module includes a sensor and a housing enclosing the sensor. The housing is operably coupled to the tubular body and includes a distal end cap. The distal crimp sleeve is operably coupled to the distal end cap and extends proximally therefrom. The longitudinal axis of the distal crimp sleeve is generally parallel to a longitudinal axis of the housing.

Abstract: An electrical lead in which a transitional coil conductor near a proximal end of the lead is electrically connected to a wire conductor distal of the coil conductor. The transitional coil is connected to an electrical connector at the proximal end of the lead. The electrical connector may be a standard ring and pin connector such as an IS-1 standard electrical connector often used in implantable medical devices. A second coil conductor runs substantially the entire length of the lead from its proximal to its distal end. The transitional coil is connected to the wire conductor through a coupling. The coupling includes a channel configured to receive the second coil conductor to allow it to run through the coupling. The coupling further includes a coil receiver configured to receive the distal end of the transitional coil to hold it in electrical contact with the electrically conductive body of the coupling.

Abstract: An electrode assembly for a body implantable lead comprises a longitudinally extending dispenser housing having an internal cavity with opposed longitudinally extending openings for storing a drug to be dispensed. A tip electrode integral and axially aligned with the dispenser housing has a face adapted for positioning adjacent the desired body site, a transverse channel formed into and transversely across its face, and an orifice extending between the channel and the internal cavity for elution of the drug to the desired body site. A weld sleeve integral and axially aligned with the dispenser housing distant from the tip electrode has an outer peripheral surface for engageably receiving one end of an elongated electrical conductor, and a collar spaced from the dispenser housing. The electrical conductor is welded to the collar to obtain a welded connection for electrical continuity between the tip electrode and the electrical conductor.
