ELECTRICAL STIMULATION SYSTEM WITH INTRAOPERATIVE CABLE AND METHODS OF MAKING AND USING

摘要

An operating room cable assembly for electrically coupling at least one implantable electrical stimulation lead to a trial stimulator includes an elongated body; a trial stimulator connector disposed at one end of the elongated body; and a lead connector disposed at another end of the elongated body. The lead connector can include one or more buttons that can be pushed to load a lead into the lead connector and released to retain the lead. Alternatively, the lead connector can include a lever that can be operated to load the lead. A further alternative is a slider with a lead engagement element that can be slid between positions allowing loading of a lead and engagement of the lead. Other alternatives include a lead connector with doors that can swing open to allow loading of a lead or a collet/sleeve that can be tightened on the lead.

主权项

1. An operating room cable assembly for electrically coupling at least on electrical stimulation lead to a trial stimulator, the operating room cable assembly comprising:
an elongated body having a first end portion and an opposing second end portion; a trial stimulator connector disposed along the second end portion of the elongated body; and a lead connector disposed along the first end portion of the elongated body and electrically coupled to the trial stimulator connector, the lead connector configured and arranged to mechanically receive a proximal end portion of at least one electrical stimulation lead or lead extension, the lead connector comprising
a connector body,at least one lead channel defined within the connector body and configured and arranged to receive a portion of the at least one electrical stimulation lead or lead extension,at least one button, each button defining at least one button lead channel configured and arranged to receive a portion of the at least one electrical stimulation lead or lead extension,at least one spring disposed within the connector body and biasing the at least one button outwards from the connector body, wherein the at least one spring biases the at least one button so that the at least one button lead channel is misaligned with the at least one lead channel and so that the at least one button can be pushed to align at least one of the at least one button lead channel with one of the at least one lead channel so that a portion of one of the at least one electrical stimulation lead or lead extension can be received therein and so that when the at least one button is released the at least one spring biases the at least one button outward to hold the at least one electrical stimulation lead or lead extension within the lead connector, anda plurality of connector contacts disposed within the connector body and arranged along the at least one lead channel and configured and arranged to make electrical contact with terminals disposed on the at least one electrical stimulation lead or lead extension when the at least one electrical stimulation lead or lead extension is received in the at least one lead channel.
