A connector assembly includes a connector body with an elongated shape and a longitudinal axis. The connector body defines a port at a first end configured to receive a proximal portion of a lead or lead extension. Contact assemblies are axially spaced-apart within the connector body and collectively form a lumen that extends from the port along the longitudinal axis of the connector body. Each contact assembly includes a spring contact disposed within a contact housing. The spring contact has a contact region that extends diagonally with respect to the longitudinal axis of the connector body. The contact region is positioned within the contact housing so that insertion of the proximal portion of the lead or lead extension into the contact housing results in a bending deflection of the contact region of the spring contact while maintaining contact between the contact region and the lead or lead extension.

A therapy lead has a distal header, a helix-shaft assembly, and a ring seal. The distal header has a cylindrical passage, and the helix-shaft assembly has a shaft and a helical anchor distally extending from the shaft. The shaft extends through the cylindrical passage. The ring seal circumferentially extends about the shaft and inside the cylindrical passage. The ring seal has a proximal face, a distal face, an outer circumferential surface, an inner circumferential surface, and a side wall. The distal face is opposite the proximal face. The outer circumferential surface extends between the proximal face and distal face. The inner circumferential surface is opposite the outer circumferential surface and extends between the proximal face and distal face. The inner circumferential surface defines a center hole of the ring seal that extends between the proximal face and distal face. A side wall extends in a continuous ring about the center hole and is defined by the proximal face, the distal face, the outer circumferential surface, and the inner circumferential surface. The side wall includes a radial cross section that is at least generally chevron-shaped.

Implantable therapy lead including bi-directional rotary blood ring seal

Methods of manufacturing implantable electrotherapy leads are disclosed herein. In one embodiment, the lead is manufactured by receiving a length of lead stock, forming an opening in a jacket at an intermediate location, interrupting a selected cable conductor, connecting a crimp connector to a proximal portion of the interrupted conductor at the opening, connecting a conductive element to the crimp connector, and removing at least a segment of a distal portion of the interrupted conductor from a lead body.

Method for manufacturing an implantable cardiac electrotherapy lead

An implantable lead assembly is provided that comprises a lead body having a proximal end portion and a distal end portion, and having a length extending there between. A plurality of electrodes are disposed along the lead body. A plurality of cable conductors are contained within the lead body, the conductors extending from the electrodes to the proximal end portion. A lead connector is provided at the proximal end portion. The lead connector includes a connector pin configured to mate with a corresponding header contact; a first termination pin coupled to one of the plurality of cable conductors; a collar coupler securely and electrically coupling the connector pin and first termination pin in an axially offset alignment with one another; and a body segment that is elongated along a longitudinal axis and extends between a header mating face and a lead mating end. The body segment is over-molded about the connector pin, the first termination pin and the collar coupler, the connector pin extending from the header mating face, the first termination pin extending from the lead mating end.

Implantable lead assembly

Example implantable cardiac electrotherapy leads are disclosed herein. In an example, a lead may include a plurality of cable conductors within an insulating jacket. A first one and a second one of the conductors include a proximal end at a proximal end of the jacket, the second conductor extends to at least the distal end of the jacket, and the first conductor includes a distal end at an intermediate location between the proximal end and the distal end of the jacket. The lead may also include a crimp connector connected to the first one of the cable conductors at the intermediate location, as well as a conductive element that may be connected to the crimp connector. A number of conductors along the proximal portion of the jacket may be greater than a number of conductors along at least a segment of the distal portion of the jacket.

Multiple-cable lead with interrupted cable and crimp configuration

A medical device configured to be secured to an individual may include a housing containing one or more electrical components, and one or more leads electrically connected to the housing. Each lead may include an insulating jacket that surrounds a central core including one or more conductors, and at least one pressure-resisting member integrally formed with one or both of the insulating jacket or the central core. The pressure-resisting member is configured to resist one or more forces exerted into the central core. For example, the pressure-resisting member may include one or more of a suture-anchoring member or a lead-strengthening member.

Medical device lead assembly having integrated pressure-resisting member

A method of manufacturing an implantable medical lead is disclosed herein. The method may include: providing a lead body including a proximal end, a distal end, and an electrode near the distal end; provide a conductor extending between the proximal and distal ends; providing a crimp including a ribbon-like member and extending the ribbon-like member around the conductor; and mechanically and electrically connecting the ribbon-like member to the electrode.

An implantable active fixation lead includes an outer sheath, a protector member having a peripheral surface extending between its distal and proximal end surfaces with a helical groove formed in the peripheral surface, and a fixation helix integral with the outer sheath. The fixation helix includes a tip end engageable with body tissue and slidably engaged with the helical groove for relative translation and rotation. A longitudinal force on the lead firmly engages the protector member's distal end surface with the body tissue. With the fixation helix initially retracted proximally of the protector member's distal end surface and disengaged from the body tissue, upon application of torque to the outer sheath, the distal end surface of the protector member is moved proximally with respect to the fixation helix which, simultaneously, is extended distally beyond the distal end surface of the protector member to an extended position into engagement with the body tissue.
