Medical lead fastener including integrated clamp

摘要

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.

主权项

1. 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 wherein the flexible clamp and the rigid body are formed from a unitary construction; and an actuator comprising a rotatable actuation member, wherein rotation of the rotatable actuation member is configured to actuate the clamp protrusion to change a perimeter of the clamp aperture, wherein the change of the perimeter of the clamp aperture by the rotatable actuation member 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.
