Described is a medical device lead including a lead body having a conductor lumen including an inner surface. The lead also includes a conductor assembly extending through the conductor lumen; the conductor assembly comprising a conductor member and an outer insulative layer; and an electrode coupled to the conductor cable. The outer insulative layer includes a textured external surface that reduces the coefficient of friction between the outer insulative layer and the inner surface of the conductor lumen through which the conductor assembly extends. Methods of forming the conductor assembly are also described.

An implantable lead includes a flexible lead body, a plurality of conductor wires and a plurality of electrodes. The implantable lead also includes a terminal connector assembly coupled with a proximal end of the lead body. The terminal connector assembly is sized to be inserted into and received by a connector port of a pulse generator header. The terminal connector assembly includes a plurality of axially spaced terminal ring elements each electrically coupled to at least one of the conductor wires. The terminal ring elements are separated from one another by an electrically insulating material. Each of the terminal ring elements includes an outer surface having a first portion and a second portion, the first portion being electrically conductive and the second portion being electrically non-conductive.

One embodiment of the present invention relates to an implantable medical device ('IMD') that can be programmed from one operational mode to another operational mode when in the presence of electro-magnetic interference ('EMI'). In accordance with this particular embodiment, the IMD includes a communication interface for receiving communication signals from an external device, such as a command to switch the IMD from a first operation mode to a second operation mode. The IMD further includes a processor in electrical communication with the communication interface, which is operable to switch or reprogram the IMD from the first operation mode to the second operation mode upon receiving a command to do so. In addition, the IMD includes a timer operable to measure a time period from when the processor switches the IMD to the second operation mode. In accordance with this aspect of the invention, the processor is in electrical communication with the timer, and is further operable to switch the IMD from the second operation mode back to the first operation mode when the measured time period reaches a predetermined time period.

The present invention pertains to polyisobutylene urethane, urea and urethane/urea copolymers, to methods of making such copolymers and to medical devices that contain such polymers. According to certain aspects of the invention, polyisobutylene urethane, urea and urethane/urea copolymers are provided, which comprise a polyisobutylene segment, an additional polymeric segment that is not a polyisobutylene segment, and a segment comprising a residue of a diisocyanate. According to other aspects of the invention, polyisobutylene urethane, urea and urethane/urea copolymers are provided, which comprise a polyisobutylene segment and end groups that comprise alkyl-, alkenyl- or alkynyl-chain-containing end groups.

A medical electrical lead comprises a flexible, elongate lead body extending along a longitudinal axis and having a proximal end and a distal end. A protective distal tip structure is disposed on the distal end of the lead body. The tip structure includes a plurality of compliant projections each extending distally from the distal end of the body in the direction of the longitudinal axis. The projections are configured to contact and bear against cardiac tissue when the lead is implanted, and are deformable under the action of an axially or radially directed force. The projections optionally include a coating over a substrate. The coating can include a hydrogel material and/or a pharmaceutical agent such as a steroid for reducing inflammation at the implantation site.

A cardiac lead comprising a lead body extending from a proximal end portion to a distal end portion; a cardiac electrode disposed along the lead body; and a coating associated with at least a portion of the electrode, the coating comprises a conductive polymer.

Conductive polymeric coating with optional biobeneficial topcoat for a medical lead

A lead includes a lead body extending from a lead proximal end portion to a lead distal end portion and having an intermediate portion therebetween, one or more tissue sensing/stimulation electrodes disposed along the lead body, one or more terminal connections disposed along the lead proximal end portion. The lead further includes one or more conductors contained within the lead body extending between the tissue sensing/stimulation electrodes and the terminal connections, and a fibrous matrix coating is disposed onto at least a portion of the lead body and/or sensing/stimulation electrodes.

Lead with fibrous matrix coating and methods related thereto

One embodiment of the present invention relates to a telemetry device which is in communication with an MRI system, and which is operable to communicate with an implantable medical device (IMD). The telemetry device includes a controller and telemetry circuitry. In one embodiment, the telemetry device is operable to automatically detect the presence of an IMD, and determine if the IMD is in an MRI-safe mode. If the IMD is not in an MRI-safe mode, the telemetry device can initiate processing to prevent the MRI system from conducting an MRI scan while the IMD in not in an MRI-safe mode.
