Robert Turcott: Method for monitoring patient using acoustic sensor. Pacesetter, Steven M Mitchell, March 4, 2003: US06527729 (572 worldwide citation)

A method for monitoring the progression of the disease of a heart failure patient is provided. An implantable or other ambulatory monitor senses acoustic signals including heart and lung sounds within the patient. Significant changes in the energy content of either the heart or lung sounds is indica ...

Robert Turcott: Method for monitoring heart failure. Pacesetter, Steven M Mitchell, November 12, 2002: US06480733 (414 worldwide citation)

A method for monitoring the progression of the hemodynamic status of a heart failure patient. An implantable or other ambulatory monitor senses the patient's electrocardiogram (ECG) and calculates R-R intervals. The R-R intervals are used to calculate a measure of heart rate variability (HRV). ...

Robert Turcott: Method for monitoring heart failure via respiratory patterns. Pacesetter, Steven M Mitchell, July 29, 2003: US06600949 (246 worldwide citation)

A method for monitoring the condition of a heart failure patient using respiration patterns is provided. An implantable or other ambulatory monitor senses the patient's respiratory patterns to identify the presence of periodic breathing or Cheyne-Stokes respiration. In a first embodiment, mecha ...

Eric S Fain, Mary E Bush: Double jaw apparatus for attaching implanted materials to body tissue. Ventritex, Steven M Mitchell, Mark J Meltzer, March 1, 1994: US05290299 (243 worldwide citation)

A system is provided for fastening an implantable medical device, for example a defibrillator lead, to the heart. A lead electrode is placed in a desired position against the pericardium, pericardial tissue is grasped with a fastening tool, and the pericardial tissue is drawn away from epicardium an ...

Mark J Meltzer: Conforming implantable defibrillator. Ventritex, Steven M Mitchell, Mark J Meltzer, July 8, 1997: US05645586 (208 worldwide citation)

An implantable device, such as a defibrillator, has a conforming housing that is adapted to follow to the contours of the patient's body at a device implantation site, while complying with pressures applied to the patient's body and with body flexion. In one form of the invention, the device housing ...

Timothy Scott Olson, April Catherine Pixley, Michael O Williams: System and method for waveform morphology comparison. Pacesetter, Steven M Mitchell, July 14, 1998: US05779645 (186 worldwide citation)

A ventricular tachycardia (VT) complex is distinguished from a sinus tachycardia or a supraventricular tachycardia. A template based on morphology of a normal sinus rhythm is collected. A test signal is compared against the template to determine how closely the test and template signals correspond b ...

Anne M Street, Matthew G Fishler: Method for monitoring heart failure via respiratory patterns. Pacesetter, Steven M Mitchell, July 8, 2003: US06589188 (166 worldwide citation)

Detection and monitoring of periodic breathing (PB) to provide an indication of changes in the hemodynamic status of a heart failure patient is accomplished by monitoring at least one of four independent physiologic parameters. The physiologic parameters are respiratory tidal volume, respiratory rat ...
