We have designed, built and tested a novel device for placing intradural neurmodulator implants directly on the pial surface of the spinal cord. This applier tool is designed for ergonomic handling of delicate electro-mechanical devices such as the Iowa-Patch™ spinal cord stimulator implant, which is aimed at overcoming certain shortcomings in the performance of standard epidural stimulator devices. The applier is approximately 14 cm long, 6 mm in diameter, made of stainless steel components, and has simple and reliable mechanisms for the attachment and release of the implant from it. We describe the design of the device, details of its construction, and its performance during in vivo testing of somatosensory evoked potentials in an ovine model of intradural spinal cord stimulation.
我们设计、制造并测试了一种新型装置，用于将硬脊膜内神经调节植入物直接放置在脊髓的软膜表面。这种应用工具专为人体工程学操作设计，可用于操作像爱荷华贴片™脊髓刺激器植入物这样的精密机电设备，旨在克服标准硬膜外刺激器设备在性能上的某些缺点。该应用工具长约14厘米，直径6毫米，由不锈钢部件制成，并且具有简单可靠的机制，用于植入物的附着和从其上释放。我们描述了该装置的设计、其构造细节以及在硬脊膜内脊髓刺激羊模型中体感诱发电位的体内测试期间它的性能。
