  • Patent number: 9381367
    Abstract: This disclosure includes techniques for securing the proximal ends of a medical lead to the connector block of an IMD with a fastener device that incorporates a flexible clamp. A fastener device for a medical device comprising a flexible clamp forming a clamp aperture, wherein the flexible clamp includes a clamp protrusion configured to facilitate actuation of the flexible clamp, a rigid body, wherein the rigid body connects to and surrounds the flexible clamp, and an actuator configured to actuate on the clamp protrusion to change a perimeter of the clamp aperture, wherein the change of the perimeter of the clamp aperture by the actuator is configured to apply a compressive force about a perimeter of an electrical contact of a medical lead in the clamp aperture to electrically and mechanically connect the medical lead to the fastener device.

  • Publication number: 20160129267
    Abstract: Medical devices include deformable structures that contact a lead upon being compressed. A grip that a clinician may grasp and manipulate is engaged with a nose structure of a header block of the medical device, and manipulation of the grip causes compression of the deformable structure to ultimately create fixation of the lead within the header block.

  • Publication number: 20150375002
    Abstract: A one-piece electrical contact ring for use in a lead receptacle of an implantable medical device includes (i) a tubular body defining a cavity extending through the body and (ii) a plurality of resiliently deflectable elements extending from the tubular body into the cavity. The deflectable elements have a lead contacting portion configured to contact the lead when received by the cavity. The lead contacting portions of the deflectable elements in a relaxed state are located in a plane that intersects the tubular body and are configured to deflect along the plane towards the tubular body as the lead is inserted in the contact ring. The contact ring may further include a plurality of stops, each configured to (i) engage a stop portion of the elements when the elements are sufficiently outwardly deflected and (ii) inhibit further outward deflection of the elements when the stops engage the stop portions.

  • Patent number: 9162072
    Abstract: An implantable medical device with lubricious material permits implantable medical devices to have a reduced friction between the device and at least a portion of the surrounding tissue. The implantable medical device may have a housing or it may have a housing and a member for providing a smooth interface between the device and the tissue. The lubricious material may be provided on or impregnated in the housing or the member. In some embodiments, the device is configured for implantation in the head of a human body. In other embodiments, the device is configured for implantation between the cranium and the scalp. In some embodiments, the device includes a single module while in other embodiments a plurality of modules are coupled together to provide a smaller profile.
