Electrical stimulation system with intraoperative cable and methods of making and using
First Claim
1. An operating room cable assembly for electrically coupling an 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 a first electrical stimulation lead or lead extension, the lead connector comprisinga connector body,a first lead channel defined within the connector body and configured and arranged to receive a first portion of the first electrical stimulation lead or lead extension,a first button defining a first button lead channel configured and arranged to receive a second portion of the first electrical stimulation lead or lead extension,a first spring disposed within the connector body and biasing the first button outwards from the connector body, wherein the first spring biases the first button so that the first button lead channel is misaligned with the first lead channel and so that the first button can be pushed to align the first button lead channel with the first lead channel so that the first and second portions of the first electrical stimulation lead or lead extension can be received in the first lead channel and the first button charnel, respectively, and so that when the first button is released the first spring biases the first button outward to hold the first electrical stimulation lead or lead extension within the lead connector,a plurality of first connector contacts disposed within the connector body and arranged along the first lead channel and configured and arranged to make electrical contact with terminals disposed on the first electrical stimulation lead or lead extension when the first electrical stimulation lead or lead extension is received in the first lead channel; and
a first side-loading lead aperture associated with the first lead channel and sufficiently sized so that the first portion of the first electrical stimulation lead or lead extension can be laterally loaded into the first lead channel.

Abstract
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.
