Abstract

A versatile, microprocessor-based stimulator for skeletal muscle cardiac assist (SMCA) has been designed, constructed, and used in several studies. The stimulator uses multiple bipolar electrodes to deliver arbitrarily specified electrical stimulus sequences to three nerve branches of the latissimus dorsi muscle. The electrodes are electrically isolated to effect regional stimulation of the muscle. The width, amplitude, and interpulse interval of each pulse in the stimulus sequence are independently variable, and the three channels are independently programmable, allowing a wide variety of stimulus patterns. Battery powered units have been used in studies for up to one year. In this paper, the stimulator and sample applications in SMCA are described.

摘要

一种用于骨骼肌心脏辅助（SMCA）的多功能、基于微处理器的刺激器已被设计、制造并用于多项研究中。该刺激器使用多个双极电极向背阔肌的三个神经分支传递任意指定的电刺激序列。电极通过电隔离来实现对肌肉的局部刺激。刺激序列中每个脉冲的宽度、幅度和脉冲间隔均可独立变化，并且三个通道可独立编程，从而允许产生多种刺激模式。电池供电的装置已在研究中使用长达一年。本文描述了该刺激器及其在SMCA中的示例应用。
