Emergency Energy Transfer System for Implantable Ventricular Assist Devices

In order to use a transcutaneous energy transmission system safely, we have devised the emergency energy transfer system which is used when the electric power supply is stopped. Emergency port through the skin consists of two copper meshes arranged coaxially and filler silicones and the electric power is supplied to the embedded devices when the continuity needle of double pipe structure is stuck in the emergency port. We determined the dimensions of the emergency port and performed the continuity test. The emergency port was connected to light emitting diode and continuity was confirmed by turning on the light emitting diode. The continuity needle was stuck in the other three places in the emergency port. As a result of the experiment, we checked the current was flowed once. In the current structure, the continuity needle is easy to come off due to the elasticity of filler silicones. So that we will improve the structure of emergency port to prevent the continuity needle coming off.
