US Classification:

600459, 607 4

Abstract:

An apparatus comprising an implantable acoustic transducer, an acoustic transducer interface circuit communicatively coupled to the acoustic transducer, and a controller circuit communicatively coupled to the acoustic transducer interface circuit. The controller is configured to, in response to receiving an indication of a patient condition associated with a development of a blood vessel obstruction, initiate delivery of acoustic energy that mitigates the blood vessel obstruction. Other systems and methods are described.

International Classification:

A61N 1/00

US Classification:

607 60, 607 32

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.

International Classification:

A61B 5/0205

US Classification:

600484

Abstract:

Systems and methods for reducing power consumption in implantable medical devices (IMDs) in which an IMD implantable in an artery monitors blood pressure. A master device monitors a physiological signal, such as respiratory cycle, and instructs the IMD to take blood pressure measurements over a sampling interval, the duration of which is determined by the master device based on the monitored physiological signal. The master device may determine an end-expiration point of the respiratory cycle and send synchronization information to the IMD to further shorten the sampling interval by coinciding the sampling interval with the end expiration point of the respiratory cycle. The IMD may further conserve power by including processing abilities to collect and/or transmit only a subset of data representing the blood pressure signal, for example, systolic, diastolic, and/or mean blood pressure signal values. The blood pressure readings, once taken, may be transferred to the master device.
