A method of forming a medical device contact element includes annealing an elongated rod of Ti-15Mo alloy material to form an annealed rod having a Young's Modulus of less than 13.5 Mpsi and an elastic range or strain of at least 0.7%. Then forming a contact ring element from the annealed rod and assembling the contact ring element into a medical device. Contact rings and lead receptacles including the same are also described.

Titanium alloy contact ring element having low modulus and large elastic elongation

A electrical contact for coupling a contact of a medical lead with electronics of a medical device including a contact member having a ring shaped wall defined by a ring inner diameter and ring outer diameter, a housing having a ring shape defining an opening therein, the opening configured to receive the medical lead therein, wherein the housing is defined in part by a housing longitudinal axis and a housing inner diameter, the contact member having at least one deflectable finger extending from the ring shaped wall into a contact opening defined by the ring inner diameter of the ring shaped wall, wherein the finger extends to a distal end and has side edges, the side edges of the finger disposed at respective angles relative to the housing longitudinal axis.

Electrical contact for a medical device lead

In some examples, the disclosure relates to a medical device such as an implantable medical lead. The medical lead may include: a lead body including an electrically conductive lead wire; an electrical contact on a proximal portion of the lead body, the electrical contact including a contact substrate; and an electrode on a distal portion of the lead body, the electrode including an electrode substrate, wherein the electrode substrate is electrically coupled to the contact substrate via the electrically conductive lead wire, wherein the lead wire is formed of a composition comprising titanium or titanium alloys, wherein the electrode substrate is formed of a first beta-titanium alloy, and wherein the contact substrate is formed of a second beta-titanium alloy.

Medical leads and techniques for manufacturing the same

A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Minimally invasive implantable neurostimulation system

A medical device system for delivering a neuromodulation therapy includes a delivery tool for deploying an implantable medical device at a neuromodulation therapy site. The implantable medical device includes a housing, an electronic circuit within the housing, and an electrical lead comprising a lead body extending between a proximal end coupled to the housing and a distal end extending away from the housing and at least one electrode carried by the lead body. The delivery tool includes a first cavity for receiving the housing and a second cavity for receiving the lead. The first cavity and the second cavity are in direct communication for receiving and deploying the housing and the lead coupled to the housing concomitantly as a single unit.

A medical electrical lead having a conductor assembly covered by an insulating layer, and a shield covering positioned adjacent or proximate to at least a portion of the insulating layer in order to shield the conductor assembly from one or more electromagnetic fields. The shield covering is formed of a polymer-matrix composite. The polymer-matrix composite includes a polymeric resin having discontinuous conductive fillers provided therein. The discontinuous conductive fillers include one or more of nano-sized metal structures and nano-sized non-metallic conductive structures. The nano-sized non-metallic conductive structures can have a coating formed of one or more metals. The nano-sized non-metallic conductive structures can be formed of carbon. In turn, the nano-sized non-metallic conductive structures can include one or more of carbon nanofibers, carbon filaments, carbon nanotubes, and carbon nanoflakes.

An implantable medical device (IMD) has a housing enclosing an electronic circuit. The housing includes a first housing portion, a second housing portion and a joint coupling the first housing portion to the second housing portion. A polymer seal is positioned in the joint in various embodiments. Other embodiments of an IMD housing are disclosed.

A temporary medical electrical lead includes a connector pin and a single conductor coil. The coil being close-wound and having no turns of the coil distal portion being mechanically coupled together. The coil distal portion translates a force of no greater than 0.1 lb(0.4 N) when strained 400%.

Implantable medical electrical lead construction and associated implant systems

A medical electrical lead having a conductor assembly covered by an insulating layer, and a shield covering positioned adjacent or proximate to at least a portion of the insulating layer in order to shield the conductor assembly from one or more electromagnetic fields. The shield covering is formed of a material that is electrically conductive, where the material is in a wrapped or woven form. The material is selected so as to have an effective combination of small size and high conductive surface area, e.g., as opposed to metal wire or coatings thinner than metal wire. As such, the shield covering exhibits sufficient conductivity in the presence of one or more high frequency electromagnetic fields so that interference to the operation of the conductor assembly is minimized. The material can have a coating formed of one or more metals. The material can include carbon. In turn, the carbon can be formed of one or more of carbon fiber, carbon nanofiber, and single or multi-walled carbon nanotube.
