One-to-one wireless communication method between implantable medical device and external controller

Abstract

The invention discloses a method for one-to-one wireless communication between an implantable medical device and an external controller. The receiving address of the implantable medical device and the receiving address of the external controller are distributed before communication is carried out, an address header is added to each communication data frame and is used for determining the communication address of the implantable medical device and the communication address of the external controller, and the address header comprises a destination address dst and a source address src. In the receiving process, the implantable medical device or the external controller only receives the communication data frame with the destination address dst which is the same as the receiving address of the implantable medical device or the external controller, one-to-one binding between the implantable medical device and the external controller is achieved, it is ensured that the implantable medical device and the external controller can only receive the data frames from each other, binding transmission is achieved, and communication interference is prevented.

Description

technical field [0001] The invention relates to an implantable medical system, in particular to a one-to-one wireless communication method between an implantable medical device and an external controller. Background technique [0002] Implantable medical systems usually include implantable electrical nerve stimulation systems (including deep brain electrical stimulation DBS, implantable cerebral cortex stimulation CNS, implantable spinal cord electrical stimulation SCS, implantable sacral nerve electrical stimulation SNS, implantable Vagus nerve stimulation VNS, etc.), implantable cardiac electrical stimulation system (commonly known as cardiac pacemaker), implantable drug infusion system (IDDS), etc. [0003] Taking the implantable electrical nerve stimulation system as an example, it mainly includes a pulse generator implanted in the body, electrodes and an external controller. Among them, the pulse generator is connected to the electrode through an extension wire, so tha...

Problems solved by technology

Since the radio is open, the following conflicting paths also result: path P1B between IMD 1 and ICD B, path P2A between IMD 2 and ICD A, IMD 1 and the path P12 of the implantable medical device 2, the path PAB of the external controller A and the external controller B, these conflicting paths will interfere with normal communication
