Patent number: 9357944Abstract: An implantable medical device performs impedance measurement and demodulation, such as for obtaining lead impedance measurements, or thoracic impedance measurements, such as for extracting respiration, cardiac stroke, or fluid status information. A 4-point FIR filter demodulator can be used to demodulate a two-phase current excitation waveform. The demodulator can also be used to measure noise for triggering a noise response. Among other things, an increased excitation current level can be used when noise is deemed to be present.Type: GrantFiled: January 8, 2009Date of Patent: June 7, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: Michael J.

Patent number: 8958877Abstract: An ambulatory or implantable device, such as a pacer, defibrillator, or other cardiac rhythm management device, can tolerate magnetic resonance imaging (MRI) or other noise without turning on an integrated circuit diode by selectively providing a bias voltage that can overcome an expected induced voltage resulting from the MRI or other noise.Type: GrantFiled: June 10, 2014Date of Patent: February 17, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Nicholas J.

Patent number: 8948866Abstract: During auto-threshold, autocapture, or other evoked response sensing, post-pace artifact is reduced by using a smaller coupling capacitor value than what is used when not in such an evoked response sensing configuration. This can be accomplished by borrowing another capacitor for use as the coupling capacitor. The borrowed capacitor can be a backup pacing capacitor from the same or a different pacing channel. The borrowed capacitor can also be a coupling capacitor from a different pacing channel.Type: GrantFiled: February 20, 2014Date of Patent: February 3, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Michael J.
