US Patent:

7974687, Jul 5, 2011

Filed:

Jan 21, 2008

Appl. No.:

12/017234

Inventors:

Taraneh Ghaffari Farazi - San Jose CA, US
Ruth Lyons - Glendale CA, US

Assignee:

Pacesetter, Inc. - Sunnyvale CA

International Classification:

A61B 5/04

US Classification:

600515, 607 5

Abstract:

Embodiments of the present invention are for use with implantable cardiac devices that discriminate between ventricular tachycardia (VT) and supraventricular tachyarrhythmia (SVT). Discrimination between VT and SVT can be based on: a detected absence, presence or degree of T-wave alternans leading up to the onset of a detected tachycardia; a detected absence, presence or degree of T-wave variability leading up to the onset of the detected tachycardia; and/or a detected cardiac electrical stability leading up to the onset of the detected tachycardia.

11/555166

Inventors:

Martin Cholette - Valencia CA, US
Ruth Lyons - Glendale CA, US

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 1/00

US Classification:

607 40, 607 2, 607115, 607133

Abstract:

An exemplary method for treating an eating or metabolism disorder includes calling for delivery of energy to the stomach using a pulse train that includes use of pulses with a pulse width less than approximately 20 ms, a duty cycle greater than approximately 20% and a pulse train duration of less than approximately 10 seconds and calling for delivery of energy to a vagal nerve. Various other methods, devices, systems, etc. , are also disclosed.

Appl. No.:

10/765625

Inventors:

Michael Benser - Valencia CA, US
Ruth Lyons - Glendale CA, US
Eric Falkenberg - Simi Valley CA, US

Assignee:

Pacesetters, Inc. - Sylmar CA

International Classification:

A61N 1/36

US Classification:

607 42, 607 2, 600529, 600538

Abstract:

An exemplary method includes sensing respiratory information related to tidal volume, based at least in part on the respiratory information, determining if the tidal volume is less than a limit and, if the tidal volume is less than the limit, calling for diaphragm activation at a stimulation power based on a nonincreasing monotonic relationship with respect to decreasing difference between the tidal volume and the limit. Various other technologies are also disclosed.

International Classification:

A61N 1/00

US Classification:

607 17

Abstract:

An implantable cardiac device is programmed to promote intrinsic rhythm of a patient's heart to alleviate orthostatic hypotension. In one implementation, the cardiac device is set in a reduced rate mode while the patient is in a less upright position, such as when resting in a supine position. If the patient is in intrinsic rhythm when transitioning to a more upright position, the cardiac device disables administration of any increased pacing rate for a programmed duration. In this manner, the patient will experience a more natural variation in heart rate during transition from the less upright posture to the more upright posture (e. g. , from supine to sitting or standing). On the other hand, if the patient is being paced during the transition, the cardiac device administers an increased base rate or triggers an orthostatic response algorithm.
