METHOD IN A MEDICAL TELEMETRY SYSTEM AND MEDICAL TELEMETRY SYSTEM
First Claim
1. A method in a medical telemetry system for communication between an external monitoring device and an implantable medical device (4) of said medical telemetry system, said method comprising the steps of:
- segmenting, at a transmitting end, an implantable medical device frame layer packet into one or more data blocks of a radio packet, said data blocks being transmitted in the communication between said external monitoring device (3) and said implantable medical device,indicating a start of said implantable medical device frame layer packet by including in a first data block a segmentation and reassembly indicator having a first value,transmitting, at said transmitting end, said radio packet data blocks over a short-range medical radio link, andreassembling, at a receiving end, said data blocks into the originally transmitted implantable medical device frame layer packet.

Abstract
In a method and a medical telemetry system for communication between an external monitoring device and an implantable medical device of the medical telemetry system at a transmitting end, an implantable medical device frame layer packet is segmented into one or more data blocks of a radio packet. The data blocks are transmitted in the communication between the external monitoring device and the implantable medical device. A start of the implantable medical device is indicated in the frame layer packet by including in a first data block of the radio packet a segmentation and reassembly indicator having a first value. At the transmitting end, the data blocks are transmitted over a short-range medical radio link. At the receiving end, the data blocks are reassembled into the originally transmitted implantable medical device frame layer packet.

11. A medical telemetry system comprising:
-
an implantable medical device configured for implantation in a patient, said implantable medical device comprising a transmitter and a receiver; an external monitoring device located extracorporeally of the patient, said external monitoring device comprising a transmitter and a receiver; said transmitter and receiver of said implantable medical device being configured to wirelessly, bi-directionally exchange communications with the transmitter and the receiver of the external monitoring device; the transmitter of one of said implantable medical device or said external monitoring device being configured to segment an implantable medical device frame layer packet into at least one data block of a radio packet; said transmitter of said at least one of said implantable medical device and said external monitoring device being further configured to indicate a start of said implantable medical device frame layer packet by including, in a first data block, a segmentation and reassembly indicator having a first value; said transmitter of said one of said implantable medical device and said external monitoring device being configured to transmit said radio packet data block via a short-range medical radio link to the receiver of the other of said implantable medical device or said external monitoring device; and said receiver of said other of said implantable medical device and said external monitoring device being configured to reassemble said data block into said originally transmitted implantable medical device frame layer packet, using said segmentation and reassembly indicator.
