Abstract
Abstract A coronary augmenter can affect blood flow in a patient. The augmenter has a timer and a stimulator. The timer can repetitively produce a trigger signal. The stimulator can repetitively apply to the patient a stimulating current sized to involuntary contract and relax at least one muscle of the patient in response to the trigger signal.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
80 words
A coronary blood flow augmenter for affecting blood flow in a patient, comprising: timing means for repetitively producing a trigger signal in response to a patient's heart beat; and stimulating means for repetitively applying to a patient a stimulating current size to involuntarily contract and relax at least one muscle in a patient in response to said trigger signal, and stimulating current being timed by said timing means to produce muscular contraction in a muscle excluding a heat during diastole.
Claim 2
Dependent Claim
80 words
A coronary blood flow augmenter for affecting blood flow in a patient, comprising: timing means for repetitively producing a trigger signal in response to a patient's heart beat; and stimulating means for repetitively applying to a patient a stimulating current size to involuntarily contract and relax at least one muscle in a patient in response to said trigger signal, and stimulating current being timed by said timing means to produce muscular contraction in a muscle excluding a heat during diastole.
Claim 3
Dependent Claim
38 words
A coronary blood flow augmenter according to claim 1 wherein said timing means is provided with a sensing means the actuate the timing means at a preselected repetition rate that is proportional to a heartbeat of a patient.
Claim 4
Dependent Claim
26 words
A coronary blood flow augmenter according to claim 2 where said stimulating means is provided with a means for controlling the duration of the stimulating current.
Claim 5
Dependent Claim
26 words
A coronary blood flow augmenter according to claim 3 wherein the sensing means comprises two monitoring electrodes externally secured to a patient to sense electrocardiac signals.
Claim 6
Dependent Claim
43 words
A coronary blood flow augmenter according to claim 4 wherein the electrocardiac signals of a patient have a repeating R-pulse corresponding to imminent systole, said stimulating means having a delay means for producing the stimulating current after a predetermined delay following the R-pulse.
Claim 7
Dependent Claim
45 words
A coronary blood flow augmenter according to claim 5 wherein said stimulating means is provided with a counter for counting the R-pulse whereby said stimulating means produces a stimulating current after the R-pulse is produced a predetermined number of times as counted by the counter.
Claim 8
Dependent Claim
28 words
A coronary blood flow augmenter according to claim 3 wherein said stimulating means is provided with a means for increasing the amplitude of the stimulating current with time.
Claim 9
Dependent Claim
29 words
A coronary blood flow augmenter according to claim 3 wherein said stimulating means comprises at least two stimulating electrodes adapted to be connected across a muscle of a patient.
Claim 10
Dependent Claim
22 words
A coronary blood flow augmenter according to claim 8 wherein said stimulating electrodes comprised two bands that are wrapped around a patient.
Claim 11
Dependent Claim
20 words
A coronary blood flow augmenter according to claim 9 wherein the two bands comprise two conductors with two electrolyte-absorbent covers.
Claim 12
Independent Claim
74 words
A method of augmenting coronary blood flow in a patient, comprising the following steps: monitoring a heart beat of a patient; developing a repetitive trigger signal in response to a heart beat of a patient; and repetitively stimulating, by a stimulating current, at least one muscle in a patient to contract and relax in response to the trigger signal, whereby muscular contraction is produced in at least one muscle, excluding the heart, during diastole.
Claim 13
Independent Claim
74 words
A method of augmenting coronary blood flow in a patient, comprising the following steps: monitoring a heart beat of a patient; developing a repetitive trigger signal in response to a heart beat of a patient; and repetitively stimulating, by a stimulating current, at least one muscle in a patient to contract and relax in response to the trigger signal, whereby muscular contraction is produced in at least one muscle, excluding the heart, during diastole.
Claim 14
Dependent Claim
37 words
A method of augmenting coronary blood flow in a patient according to claim 11 comprising the additional steps of counting the trigger signal and activating the stimulating current in response to a preselected number of trigger signals.
