Abstract:
Objective To find out a PPM-based transcutaneous wireless bidirectional communication system for implantable medical device.Methods The wireless communication system included device implanted in the body,controller and PDA outside the body.Pulse position modulation(PPM) was used for the wireless bidirectional communication between device implanted in the body and controller outside the body.Results A PPM-based transcutaneous wireless communication system was realized.Its wireless bidirectional communication distance between device implanted in the body with titanium container and controller outside the body was over two inches.This system was with good position availability.Conclusion Pulse position modulation is successfully used for transcutaneous wireless communication system,and average power consumption for communication device implanted in the body is lowered greatly compared with ASK modulation method.At the same time,the volume of communication device implanted in the body is decreased for antenna common-using idea.
