    摘要： A connector assembly mounted on an implantable cardiac stimulation device has an actuator mechanism for fixing and sealing electrical leads inserted into lead receptacles within the connector assembly without the use of setscrews. Fixing and sealing of the leads is accomplished by compressing resilient lead lock seals of O-ring shape, disposed in annular recesses, with lip portions of a plunger drawn toward the molded support by the actuator mechanism. In a first embodiment of the actuator mechanism, rotation of a cam actuator transversely journaled within the support, using a torque wrench or similar tool, moves a cam slide attached to the plunger through a fixed displacement between lock and unlock positions as an offset camming portion of the actuator engages the surfaces of a slot within the cam slide. In a second embodiment, constant-force compression of the lead lock seals by the plunger is provided by using a torque wrench to rotate a screw actuator having one end coupled to the plunger and an opposite threaded end received within a screw block transversely disposed within the support. In a third embodiment, a rotatable toothed pinion engages a toothed slot within a slidable rack to provide incremental advancement of the rack, and thereby stepped displacement and force, with a resulting increased resolution. In a fourth embodiment, compliance provided by either a spring formed within the cam slide, or a spring nut mounted thereon, prevents excessive force from being exerted on leads of larger diameter.

    摘要： An external infusion device that infuses a fluid into an individual's body includes a housing, a reservoir, a drive system, a power supply, electrical elements, and a tab. The reservoir contains the fluid, and the drive system forces the fluid from the reservoir. The electrical elements control the power to the drive system to regulate the rate that fluid is forced from the reservoir. The tab mates with the housing, and contains at least one electrical element. The tab is removable, and may be replaced with a different tab. The different tab may change the rate fluid is forced from the reservoir. A tab may be removed from one external infusion device and installed in a different external infusion device. The tab may be limited to use in a predetermined number of external infusion devices and may include a power supply.

    摘要： A connector block assembly for electrically connecting a proximal ring electrode of a bipolar pacemaker lead to the pacemaker. The connection is made in a way that maintains secure electrical contact and that prevents the delicate proximal ring electrode from being damaged or deformed. The pacemaker includes a connector block having a channel therethrough into which the proximal ring electrode is inserted. A C-ring is sandwiched between the ring electrode and an inner wall of the connector block's receiving channel. A setscrew adjustably forces the C-ring against the ring electrode. Mechanical stop means limit the transverse movement of the C-ring, thereby preventing the ring electrode from being deformed, while still maintaining a firm grasp of the ring electrode between the C-ring and the connector block. An alternative embodiment employs a resilient spring to firmly hold the ring electrode in electrical contact with the connector block.
