Abstract
Abstract An apparatus for ultrasonic irradiation of the heart either when the chest is open after surgery or through the chest wall. It may also be used in conjunction with electrical defibrillation equipment or alone. The apparatus includes an EKG for detecting the heart beat, an ultrasonic generator and timing and pulsing circuits for providing timed pulses of ultrasound to coincide with selected events in the cardiac cycle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
51 words
An apparatus for ultrasonic enhancement of cardiac contractility, comprising: - means for detecting or programming a heart beat cycle, - means for generating ultrasound, - means for providing pulses of said ultrasound, and - means to time each said pulse to coincide with a selected event in the cardiac contraction cycle.
Claim 2
Independent Claim
51 words
An apparatus for ultrasonic enhancement of cardiac contractility, comprising: - means for detecting or programming a heart beat cycle, - means for generating ultrasound, - means for providing pulses of said ultrasound, and - means to time each said pulse to coincide with a selected event in the cardiac contraction cycle.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 wherein said means for detecting a heart beat cycle is an electrocardiograph.
Claim 4
Dependent Claim
22 words
The apparatus of claim 1 wherein said means for generating ultrasound is combined with one electrode of a pair of defibrillator electrodes.
Claim 5
Dependent Claim
40 words
The apparatus of claim 1 wherein a focussing element is provided on said ultrasound generating means, for directing the ultrasound to pass between adjacent ribs in a patient's chest and then diverge to contact a greater area of the heart.
Claim 6
Dependent Claim
19 words
The apparatus of claim 1 wherein the ultrasound generating means is located in, or feeds into, a catheter probe.
Claim 7
Dependent Claim
49 words
The apparatus of claim 1 wherein a signal is acquired by EKG electrodes and said means for providing timed pulses includes a discriminator circuit, a delay circuit, a-ultrasound gating pulse circuit, and a radio frequency pulse module circuit for providing pulsed radio frequency to said means for generating ultrasound.
Claim 8
Dependent Claim
27 words
The apparatus of claim 1 wherein the ultrasound generator is adapted to generate ultrasound of frequency within the range of about 20 KHz to about 25 MHz.
Claim 9
Independent Claim
27 words
An apparatus for heart defibrillation and ultrasonic enhancement of cardiac contractility comprising means for generating ultrasound combined with one electrode of a pair of electrical defibrillator electrodes.
Claim 10
Independent Claim
27 words
An apparatus for heart defibrillation and ultrasonic enhancement of cardiac contractility comprising means for generating ultrasound combined with one electrode of a pair of electrical defibrillator electrodes.
