摘要： A miniature plastic gripper actuated by inflation of a miniature balloon and method of fabricating same. The gripper is constructed of either heat-shrinkable or heat-expandable plastic tubing and is formed around a mandrel, then cut to form gripper prongs or jaws and the mandrel removed. The gripper is connected at one end with a catheter or tube having an actuating balloon at its tip, whereby the gripper is opened or closed by inflation or deflation of the balloon. The gripper is designed to removably retain a member to which is connected a quantity or medicine, plugs, or micro-components. The miniature plastic gripper is inexpensive to fabricate and can be used for various applications, such as gripping, sorting, or placing of micron-scale particles for analysis.

The gripper is connected at one end with a catheter or tube having an actuating balloon at its tip, whereby the gripper is opened or dosed by inflation or deflation of the balloon. The gripper is designed to removably retain a member to which is connected a quantity or medicine, plugs, or micro-components.

摘要： Electromechanical microstructures (microgrippers), either integrated circuit (IC) silicon-based or precision machined, to extend and improve the application of catheter-based interventional therapies for the repair of aneurysms in the brain or other interventional clinical therapies. These micromechanisms can be specifically applied to release platinum coils or other materials into bulging portions of the blood vessels also known as aneurysms. The "micro" size of the release mechanism is necessary since the brain vessels are the smallest in the body. Through a catheter more than one meter long, the micromechanism located at one end of the catheter can be manipulated from the other end thereof. The microgripper (micromechanism) of the invention will also find applications in non-medical areas where a remotely actuated microgripper or similar actuator would be useful or where micro-assembling is needed.
摘要翻译： 机电微结构（microgrippers），集成电路（IC）硅基或精密加工，以扩展和改进基于导管的介入治疗在脑或其他介入性临床治疗中的动脉瘤修复的应用。 这些微机制可以专门用于将铂线圈或其他材料释放到也被称为动脉瘤的血管的隆起部分。 释放机制的“微”尺寸是必要的，因为脑血管在体内是最小的。 通过超过一米长的导管，位于导管一端的微机构可以从其另一端被操纵。 本发明的微夹持器（微机构）也将在非医疗领域中得到应用，其中远程致动的微爪或类似的致动器将是有用的或者在需要微组装的地方。
