Filed:

Jun 15, 2011

Appl. No.:

13/161093

Frazier Frantz - Chesapeake VA, US

International Classification:

G09B 23/28

US Classification:

434262

Abstract:

Computer systems and methods are provided for training surgeons to perform the Nuss procedure, a surgery for correcting pectus excavatum (PE), and for planning such procedures. PE is a congenital chest wall deformity, and the Nuss procedure is a minimally invasive surgery that involves implantation of a corrective bar. A surgical trainer and planner may be based on one or more of the biomechanical properties of the PE ribcage, deformable models, and visualization techniques.

International Classification:

A61N 1368

US Classification:

607 15

Abstract:

A method and system for applying therapeutic electrical pulses to the heart includes a plurality of spaced apart electrodes. Each electrode in electrical communication with a pulse generator and are operative to deliver at least one energy pulse to a patient's heart. Sensors and electrical communication with a controller are operative to detect an abnormal rhythm in the patient's heart and transmit a signal to a controller to indicate an abnormal rhythmic condition. The controller is configured to receive the abnormal rhythmic signal from the sensor and cause the pulse generator to emit a sequence of spatially and temporally distinct pulses through the electrodes, each pulse passing through at least one of the electrodes.

Abstract:

An electrode terminal is described for delivering a stimulation pulse to the heart or other tissues containing a linear array of fibers. The electrode terminal is elongated and adapted for orientation in a direction parallel to the tissue fibers. The device of the present invention further includes a power source for electrically energizing the terminal such that the energization of the terminal reduces the nonuniformity of the transmembrane voltage change in the tissue proximate the electrode which is produced during the stimulation pulse. Nonuniform transmembrane voltage changes are associated with arrhythmic conditions. The linear electrode of the present invention can be used for cardiac pacing, defibrillation, and the termination of tachycardia.
