摘要： A percutaneous implanted device for temporarily sustaining a patient awaiting a heart transplant. The device includes a radially expandable stent mounted upon the balloon section of a balloon catheter. A venous biological valve is mounted at each end of the stent and an inflatable annular-shaped diaphragm is secured to the stent between the valves, which permit the flow of blood in one direction and prevent the flow of blood in the opposite direction. The diaphragm is attached to a pump which inflates the diaphragm after the stent is implanted in a blood vessel in relation to the heart's rhythm to assist the heart in moving blood through the patient's circulatory system.

摘要： A ventricular assistive device (VAD) based on a progressive cavity pump includes a pump housing having an inlet and an outlet, a pump stator contained within the pump housing, a pump rotor rotatably disposed within the pump stator, a motor including a motor rotor contained within the pump housing and a direct drive means connected between the motor rotor and an axial shaft of the pump rotor for rotating the pump rotor. The motor rotates the motor rotor, which in turn rotates the pump rotor through the direct drive means. The rotation of the pump rotor within the pump stator forms a plurality of cavities that carry blood forward through the pump housing from the inlet to the outlet as the motor drives the direct drive means.

摘要： A system for improving heart muscle response during a pre-ejection phase in the heart muscle pumping cycle requires a catheter having a pressure transducer and a fluid device mounted at its distal end. Also included is a pump connected to the proximal end of the catheter in fluid communication with the fluid device. A computer will activate the pump in response to a predetermined signal from the pressure transducer to inject and maintain an increased fluid volume in the pumping chamber of the heart for a predetermined time interval Δt during the pre-ejection phase. This supplements the isometric pressure in the heart's pumping chamber in preparation for a subsequent ejection of blood from the pumping chamber.

摘要： A prosthetic blood valve comprises a base body having a hollow, opposing props extending from the body to partition opposing inclined ridges of the body to allow the inclined ridges and each top of the props to define the hollow and to form an upper surface of the body, and a singular leaflet attached to and along the inclined ridges and the prop tops to cover the hollow. The singular leaflet has a substantially central opening between the props and formed of a flexible material so a forward or outward blood flow passes through the opening and a reverse flow or backflow of blood leads to opposing leaflet portions around the opening being abuttingly pulled to each other to thereby prevent the blood backflow.

摘要： Fluid transfer device configured as a vacuum pump particularly suited for nondestructive transfer of fluids, including blood and blood constituents. Fluid transfer device used for assisting in the pumping of blood through a patient's heart for reducing the load on the heart, reducing forces and blood pressure on the inner walls of the heart is reduced. Examples are aortic assist device, a ventricular assist device, or artificial heart. Industrial applications include the pumping of fluids, including destructible fluids such as foodstuff with or without food constituents of various sizes within the foodstuff. Food and other fluids may be stored until they are dispensed. By use of a vacuum, the device is operated at no more than atmospheric pressure. A pre-charged pressure tank may be used, such as where fluid pressure of the pumped fluid, including backpressure of body fluids, where pressure greater than atmospheric is required to expel pumped fluid.

摘要： A pump especially designed for pumping blood comprises a bladder, the interior surface area and volume of which is changeable, i.e., it stretches and expands during the filling phase, and elastically contracts to its normal relaxed size during the ejection phase. The bladder has a fluid inlet and a fluid outlet. A device, such as a vacuum pump, alternately expands and contracts the interior surface area and volume of the bladder. Most of the interior surface area of the bladder expands and contracts in each cycle. One or more check valves or other means for causing substantially one-way fluid flow through the bladder are also provided. The pump of the invention decreases the likelihood of blood clots forming in the pump, decreases the risk of damage to blood cells, improves the pumping characteristics of the device, and decreases or eliminates the chance of foreign fluids passing into the blood stream should a tear or break occur in the bladder.
