Abstract: An operating room cable for electrically coupling a lead to a trial stimulator includes a trial stimulator connector electrically coupleable with the trial stimulator and a lead connector for receiving the lead. The lead connector includes a housing. A first lead aperture is defined in a second end of the housing in proximity to a first side of the housing. A first inner passage extends along an interior of the housing from the first lead aperture to the second end of the housing. A first stylet slit is defined along the first side of the housing and extends from a first end of the housing to the second end of the housing. The first stylet slit is formed between upper and lower casings of the housing. The first stylet slit is continuous with the first lead aperture and the first inner passage.

Abstract: Circuitry for generating a compliance voltage (V+) for the current sources and/or sinks in an implantable stimulator device in disclosed. The circuitry assesses whether V+ is optimal for a given pulse, and if not, adjusts V+ for the next pulse. The circuitry uses amplifiers to measure the voltage drop across active PDACs (current sources) and NDAC (current sinks) at an appropriate time during the pulse. The measured voltages are assessed to determine whether they are high or low relative to optimal values. If low, a V+ regulator is controlled to increase V+ for the next pulse; if not, the V+ regulator is controlled to decrease V+ for the next pulse. Through this approach, gradual changes that may be occurring in the implant environment can be accounted for, with V+ adjusted on a pulse-by-pulse basis to keep the voltage drops at or near optimal levels for efficient DAC operation.
