Appl. No.:

13/746818

Inventors:

Robert M. Ecker - Lino Lakes MN, US
Kaustubh R. Patil - Blaine MN, US
Michael B. Terry - Camas WA, US
Jonathan P. Roberts - Coon Rapids MN, US
Robert A. Corey - Arden Hills MN, US

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 1/36
A61N 1/378

US Classification:

607 60, 607 2, 607 32

Abstract:

This disclosure is directed to the synchronization of clocks of a secondary implantable medical device (IMD) to a clock of a primary IMD. The secondary IMD includes a communications clock. The communications clock may be synchronized based on at least one received communications pulse. The secondary IMD further includes a general purpose clock different than the communications clock. The general purpose clock may be synchronized based on at least one received power pulse. The communications clock may also be synchronized based on the at least one received power pulse.

International Classification:

A61B 5/0205

US Classification:

600484, 600529

Abstract:

An apparatus for determining a respiration parameter in a medical device in which a pressure sensor senses pressure signals, and a signal processor, coupled to the pressure sensor, receives the sensed pressure signals and generates corresponding sample points. A microprocessor continuously adjusts a breath detection threshold in response to the generated sample points to generate a current adjusted breath detection threshold, compares a current generated sample point to the current adjusted breath detection threshold, suspends the continuous adjusting of the breath detection threshold and sets the breath detection threshold equal to the most current adjusted breath detection threshold generated prior to the suspending, and determines the respiration parameter in response to a comparing of a next generated sample point to the set breath detection threshold

Appl. No.:

13/455264

Inventors:

Robert A. Corey - Arden Hills MN, US

International Classification:

A61N 1/365
A61N 1/39

US Classification:

607 4, 607 17

Abstract:

The accuracy of data processing operations in an electronic device is improved through reductions in errors associated with data acquisition, reading, and transmission. In one embodiment, two or more modules of an integrated circuit are operated at different clock speeds and a voting scheme is utilized to obtain a valid data value from one of the modules. The disclosure describes methods, devices and systems that utilize the voting schemes to eliminate errors induced by race conditions in obtaining valid data values during data transfer by obtaining a plurality of data samples while the communicating modules are operating at the different clock speeds and selecting from among the data samples the valid data value.

International Classification:

A61N 1/378
A61N 1/372

Abstract:

An example medical device includes a battery configured to provide power to the medical device and stimulation circuitry configured to generate an electrical stimulation signal. The medical device includes hibernation control circuitry configured to cause the medical device to enter a hibernation mode in response to a hibernation trigger and exit the hibernation mode in response to a wake-up trigger. The medical device includes a switch configured to open in response to the hibernation control circuitry causing the medical device to enter a hibernation mode and close in response to the hibernation control circuitry causing the medical device to exit the hibernation mode and isolation interface circuitry configured to prevent power leakage from the hibernation control circuitry to the stimulation circuitry when the medical device is in hibernation mode. The stimulation circuitry is not powered by the battery when the medical device is in the hibernation mode.
