摘要： An implantable medical lead configured for active fixation in the vasculature of a patient includes an elongated lead body having a central lumen and a distal tip. Disposed within the central lumen are a fixation helix and an elongated member, such as a lead coil, coupled to the fixation helix. The elongated member is adapted to rotate the fixation helix, thereby causing it to advance or retract within the central lumen of the lead body. The lead body includes a window along a portion of its length through which the fixation helix may be affixed to a blood vessel of the patient's vasculature.

摘要： A connector sleeve includes a lumen adapted to receive a medical lead connector wherein a retention element engages a retention edge formed at a distal end of a connector element included on the lead connector. The connector sleeve further includes a contact element adapted to electrically engage the lead connector element within the lumen and an external conductive surface electrically coupled to the contact element and adapted for electrical engagement within the connector bore of an implantable medical device.

摘要： A distal tip coupled to a body of an implantable medical device includes a canted passageway extending distally from a lumen of the body and an opening terminating the passageway and positioned in proximity to a distal end of the distal tip; a helical fixation element coupled to an elongated member extending within the lumen of the body is adapted to deflect along the canted passageway of the distal tip. The elongated member is adapted to move the helical member through the passageway of the distal tip and out from the opening and to rotate the helical element thereby affixing the helical element into an implant site.
