First Claim
1. A system for in situ trimming of oscillators in a pair of implantable medical devices, comprising:
- an initiating implantable medical device, comprising;
an oscillator configured for regulating the timing of one or more operations performed by the initiating implantable medical device;
control circuitry configured to select at least one first oscillator frequency over a range of oscillator trim frequencies; and
an acoustic transducer configured to send a command in situ over each oscillator frequency selected over the range of oscillator trim frequencies;
a responding implantable medical device, comprising;
an oscillator configured for regulating the timing of one or more operations performed by the responding implantable medical device;
control circuitry configured to select at least one second oscillator frequency over the range of oscillator trim frequencies; and
an acoustic transducer configured to send a response to each of the commands received in situ over each oscillator frequency selected by each implantable medical device;
wherein the acoustic transducer of the initiating implantable medical device is configured to receive the responses from the responding implantable medical device; and
wherein the control circuitry of the initiating implantable medical device is further configured to evaluate the responses received by the initiating implantable medical device to identify a combination of oscillator trim frequencies from the at least one first oscillator frequency of the initiating implantable medical device and the at least one second oscillator frequency of the responding implantable medical device that together exhibit a strongest acoustic wave; and
wherein both implantable medical devices are configured to trim the oscillators to the identified combination of oscillator trim frequencies.

Abstract
A system and method for in situ trimming of oscillators in a pair of implantable medical devices is provided. Each frequency over a range of oscillator trim frequencies for an initiating implantable medical device is selected and a plurality of commands are sent via an acoustic transducer in situ over the frequency selected. Each frequency over a range of oscillator trim frequencies for a responding implantable medical device is selected and a response to each of the commands received is sent via an acoustic transducer in situ over the frequency selected. The responses received by the initiating implantable medical device are evaluated and a combination of the oscillator trim frequencies for both implantable medical devices that together exhibit a strongest acoustic wave is identified. Oscillators in both implantable medical devices are trimmed to the oscillator trim frequencies in the combination identified.
