Abstract: A shielded male pin connector (10) includes a rigid, insulating body (14), an elongated contact pin (18a, 18b) extending from the body and a cable (20) extending into the body (14) and connected electrically to the pin. To electrically isolate the pin, a flexible, resilient, electrically insulating tubular shield (32) encircles the pin, the shield being longer than the pin. The shield is rotatably mounted to the body (14) coaxial to the pin so that when the connector is coupled to a mating female connector (13) having a locking cap (28a, 28b) received in the shield (32), the locking cap may be turned by squeezing and rotating the shield (32).

Abstract: An endocardial pacing lead has a fixator in the form of a thin, deeply scalloped, flexible and resilient skirt that flares out from the body of the lead away from the contact tip thereof. The skirt defines a continuous frustoconical skirt portion adjacent to the body and a plurality of elongated, relatively wide, thin leaves extending from the free edge of the skirt that constitute flexible resilient extensions of the skirt.
