Abstract

Introduction: Gastric electrical stimulation (GES) is an effective treatment for gastroparesis. However, the available devices are equipped with bulky batteries that need to be replaced regularly by surgery.

Methods: Our new implantable system consists of only 6 passive components in addition to a diode and does not require a battery. Two acute porcine experiments were carried out with a robotic surgical system for placement of the prototypes. The stimulation parameters were set with an extracorporeal unit and GES was performed. The recorded electromyography (EMG) signal was subjected to a multiresolution analysis.

Results: The robot-assisted placement of the prototypes was successful. The inductive energy transfer was confirmed to be functional and EMG analysis revealed changes in gastric electrical activity.

Conclusions: Further technological and rapid regulatory solutions are being sought in order to start a clinical trial with the next generation devices in the near future.

机器人放置无线胃电刺激实验原型。

胃电刺激（GES）是治疗胃轻瘫的有效方法。然而，现有的设备都配备了笨重的电池，需要通过手术定期更换。方法：我们的新型植入式系统除了一个二极管外，仅由6个无源元件组成，并且不需要电池。两个急性猪实验进行了机器人手术系统的原型放置。用体外装置设置刺激参数，并进行GES。对记录的肌电信号进行多分辨率分析。结果：机器人辅助放置原型是成功的。感应能量传递被证实是功能性的，肌电图分析显示胃电活动的变化。结论：为了在不久的将来启动下一代设备的临床试验，正在寻求进一步的技术和快速监管解决方案。

期刊介绍： Langenbeck''s Archives of Surgery aims to publish the best results in the field of clinical surgery and basic surgical research. The main focus is on providing the highest level of clinical research and clinically relevant basic research. The journal, published exclusively in English, will provide an international discussion forum for the controlled results of clinical surgery. The majority of published contributions will be original articles reporting on clinical data from general and visceral surgery, while endocrine surgery will also be covered. Papers on basic surgical principles from the fields of traumatology, vascular and thoracic surgery are also welcome. Evidence-based medicine is an important criterion for the acceptance of papers.
