The system further provides a connector separator for maintaining electrode receiving connectors in a fixed relationship relative to each other to avoid contact between electrically exposed regions of the electrodes. The extension cable system comprises electrically conductive leads electrically connected to a plug adapted to an electrical socket of a medical device, dielectrically shrouded electrode receiving connector(s) that form an electrical connection with a filamentous electrode or electrically conductive wire, and a connector separator for gripping and maintaining the electrode receiving connectors in a predetermined and rigid relationship relative to each other. The electrode receiving connectors comprise outer shrouds that can be threadably rotated to operate wire receiving chucks to receive electrode wires.

  • Patent number: 7003351
    Abstract: An electrical contact for use in the header assembly of an implantable tissue stimulator includes a metal housing having a base and a sidewall where the opening in the base is adapted to receive the terminal of a medical lead therethrough. An electrical contact support member is welded to the edge of the sidewall and affixed to the support member are a plurality of spring members that are tangent to an imaginary circle whose diameter is slightly less than the outside diameter of the lead terminal contact rings. When the contacts are axially aligned in the device header, the terminal of an electrical lead may be longitudinally inserted into the header to establish electrical contact with device feedthrough wires that are joined to the electrical contacts in the header.

  • Patent number: 6984145
    Abstract: A connector assembly releasably affixes a lead on an implantable medical device. The lead includes a lead body. The connector assembly comprises a support, a side clamp defining with the support confronting surfaces configured to receive a proximal end portion of the lead body. A fastener is adapted to be received by the support for urging the side clamp toward the support and for clamping the proximal end portion of the lead body between the confronting surfaces. The fastener may extend through the side clamp and may be threadedly received by the support. Further, the support may carry a retainer for inhibiting the removal of the fastener from the support. The side clamp and the support may define additional confronting surfaces configured to receive a proximal end portion of an additional lead body, the fastener being adapted to urge the side clamp toward the support to clamp the proximal end portion of the additional confronting surfaces.

  • Patent number: 6915169
    Abstract: A lead having an extendable and retractable fixation mechanism has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring disposed at the distal end of the lead provides information during the implantation process.

  • Patent number: 6910906
    Abstract: A connector connects a silicone or other radially expandable catheter to a catheter that does not expand radially. The catheter includes a hollow first connection part, a hollow second connecting part and a locking sleeve. The hollow second connecting part is threadably connected to the first connection part. The second part has a rib protruding from an external surface thereof. The rib has a recessed notch. A locking sleeve has a lip projecting radially inwardly therefrom at each end. The lip at the second end is fixedly received within the recessed notch. The lip at the first end is disposed about the external surface of the connection part. The locking sleeve is axially movable with respect to the first connection part. Axial movement of the locking sleeve in one direction is limited, thereby preventing disassembly of the first connecting part and the second connecting part.

  • Patent number: 6907292
    Abstract: The invention relates to a locking device (1) for a female connector part for cooperation with an elongate, male connector part (30), said female connector part being intended for use in a pacer housing. Said female connector part comprises a longitudinal bore defining a longitudinal space for said locking device. Said locking device comprises one or several tongues (19, 19?) being swingable between two positions, a first position in which the tips of the tongues (19, 19?) can engage said male elongate connector part (30) and a second position in which the tips of the tongues (19, 19?) will not engage the male elongate connector part (30). Said tongues are biased towards said first position by means of a spring force. A pivot (9) is associated with each tongue and each tongue has a first part engaging said connector means (30) and being located on one side of said pivot and a second part being located on the other side of said pivot.

  • Patent number: RE39233
    Abstract: A consolidated monitoring cable arrangement allows multiple cables extending between a surgical gurney, or other type of patient support platform, and a peripheral monitoring stand to be consolidated into a single cable. The present use of multiple cables has the disadvantage that the region between a gurney and a monitoring stand is cluttered. This can present a hazard to medical personnel, particularly when an emergency situation requires that concentration be focused on the needs of the patient. In a primary form, the subject cable arrangement uses two boxes, one on the gurney and another on the monitoring stand; a detachable cable connects the two boxes. Shorter cables of uniform length are used to connect a patient on the gurney and equipment on the monitoring stand to a respective box. Besides the aforementioned safety advantage, this cable arrangement reduces the expense of frequent replacement of damaged cables.
