1. A method comprising:
- transmitting a series of synchronization signals during a communication sequence, wherein each synchronization signal includes an echo code, wherein the echo code corresponds to a request for a number of duplicate data units to be sent in response to detecting an error in a data unit received during the same uninterrupted communication sequence; and
for each synchronization signal, receiving a new data unit and receiving the number of requested duplicate data units from an implantable medical device (IMD), wherein the number is selected using a value of the echo code, and wherein a duplicate data unit corresponds to a data unit previously transmitted by the IMD during the same uninterrupted communication sequence.

Abstract
This document discloses, among other things, a telemetry system for requesting and receiving redundant data. A synchronization frame transmitted by an external device includes an echo code. The implantable device responds to the synchronization frame by sending real time data and echo data selected as a function of the echo code.

13. An apparatus comprising:
-
a transceiver configured to communicate wirelessly with an IMD; a processor communicatively coupled to the transceiver, wherein the processor is configured to; detect an error in a data unit received from the IMD; transmit via the transceiver, during a communication sequence, a series of synchronization signals wherein each synchronization signal includes an echo code, wherein the echo code corresponds to a request for a number of duplicate data units to be sent in response to detecting the error in the data unit received during the same uninterrupted communication sequence; and receive via the transceiver, for each synchronization signal, a new data unit and the number of requested duplicate data units from the IMD, wherein the number of duplicate data units corresponds to a value of the echo code, and wherein a duplicate data unit corresponds to a data unit previously transmitted by the IMD during the same uninterrupted communication sequence. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
