Abstract
A method, system and external instrument are provided. The method initiates a communication link between an external instrument (EI) and an implantable medical device (IMD), established a first connection interval for conveying data packets between the EI and IMD and monitors a connection criteria that includes at least one of a data throughput requirement. A battery indicator or link condition of the communications link is between the IMD and EI. The method further changes from the first connection interval to a second connection interval based on the connection criteria.
Claims16
A method, comprising:
- initiating a communications session between an external instrument (EI) and an implantable medical device (IMD), the communications session including an interrogation phase and an interaction phase, the interrogation and interaction phases having first and second connection interval (CI) schemes, respectively, the first and second CI schemes having corresponding different first and second connection intervals;
- during the interrogation phase, utilizing the first CI scheme and first connection interval for conveying data packets between the EI and IMD during the interrogation phase;
- during the interaction phase, utilizing the second CI scheme and second connection interval for conveying data packets between the EI and IMD during the interrogation phase;
- and
- changing between the first CI scheme and the second CI scheme in response to changing between the interrogation phase and the interaction phase.
An implantable medical device (IMD), comprising:
- a sensing circuit to collect sensed data;
- a memory;
- and
- a radio frequency (RF) circuit configured to:
- initiate a communications session between an external instrument (EI) and the IMD, the communications session including an interrogation phase and an interaction phase, the interrogation and interaction phases having first and second connection interval (CI) schemes, respectively, the first and second CI schemes having corresponding different first and second connection intervals;
- during the interrogation phase, utilize the first CI scheme and first connection interval for conveying data packets between the EI and IMD during the interrogation phase;
- during the interaction phase, utilize the second CI scheme and second connection interval for conveying data packets between the EI and IMD during the interrogation phase;
- and
- change between the first CI scheme and the second CI scheme in response to changing between the interrogation phase and the interaction phase.
