Abstract:
1. A method for receiving and processing telemetry of a block transmitted between an external component and an implantable medical device, comprising payload data and first error detection data relevant to at least the payload data, the method comprising: wirelessly receiving a plurality of packets transmitted from a sending device at a receiving device, each received packet comprising at least a portion of the block and second error detection data relevant to at least its associated block portion, the plurality of the received packets comprising the entirety of the block including the payload data and the first error detection data; assessing the second error detection data for each received packet, and, if valid, accepting the packet at the receiving device, and, if invalid, requesting that the invalid packet be resent to the receiving device; reconstituting the block at the receiving device using the accepted packets, the reconstituted block comprising the payload data and the first error detection data; computing a code for the payload data in the reconstituted block; and assessing the reconstituted block by comparing the code to the first error detection data, and, if valid, accepting the reconstituted block at the receiving device; wherein one of the external component and the implantable medical device comprises the sending device and the other comprises the receiving device.
