Abstract
A minimally invasive pre-cardiogenic heart assist device has been developed. A method of increasing myocardial blood flow using a Subclavian Diastolic Augmentation Device (SDAD) includes grafting a subclavian vein to a first synthetic chamber, the first synthetic chamber located inside of a body of the patient; grafting a subclavian artery to a second synthetic chamber, the second synthetic chamber located inside of the body of the patient; and pumping blood from the first synthetic chamber to the second synthetic chamber with a pump located inside of the body of the patient.
Claims17
A method of increasing myocardial blood flow in a patient comprising:
- grafting a subclavian vein to a first synthetic chamber with a first liquid volume between 5 ml and 50 ml, the first synthetic chamber located inside of a body of the patient;
- grafting a subclavian artery to a second synthetic chamber with a second liquid volume equal to the first liquid volume of the first synthetic chamber, the second synthetic chamber located inside of the body of the patient;
- and
- pumping blood from the first synthetic chamber to the second synthetic chamber and from the second synthetic chamber towards an aortic valve using a pump located inside of the body of the patient during diastole.
An assistive heart device comprising:
- a first synthetic chamber, with a first liquid volume between 5 ml and 50 ml;
- a second synthetic chamber, with a second liquid volume equal to the first liquid volume of the first synthetic chamber;
- a third synthetic chamber connecting the first synthetic chamber to the second synthetic chamber, the third synthetic chamber housing a pump;
- a driver circuit for driving the pump;
- one or more pressure sensors;
- and
- wherein the driver circuit triggers the pump to eject blood into a subclavain artery from the second synthetic chamber towards an aortic valve during diastole based, at least partially, on a reading of the one or more pressure sensors.
