    摘要： A ventricle assist device comprises an inlet for receiving blood, an outlet for discharging blood, and a chamber disposed between the inlet and the outlet. There is also a means for actuating the ventricle assist device between an expanded configuration and a contracted configuration. In the expanded configuration blood flows into the inlet. In the contracted configuration blood flows out of the outlet. There may be a one-way valve at the outlet for preventing blood flow back into the chamber. The one-way valve is a diaphragm valve. The chamber may have a resilient outer wall. The chamber may have an ovoid shape.

    摘要： Embodiments of the disclosed technology are directed to a self-contained, totally implantable blood pump that replaces the whole heart. It is a small spherical device that encloses all of its blood propulsion dynamics. The dynamics are controlled by a built-in microcontroller that regulates the speed of the motor in response to hemodynamic changes like blood pressure fluctuations, level of body activity, and/or posture. The hemodynamic changes are detected using a plurality of sensors disposed around the body. An implantable transcutaneously rechargeable battery provides power to the microcontroller, motor and/or sensors.

    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： The present invention is thus directed to methods and apparatus for decreasing pressure in a first portion of a vessel of the cardiac structure of a patient by implanting a shunt communicating with an area outside said first portion, whereby a volume of blood sufficient to reduce pressure in said first portion is released. Preferably, the first portion comprises the left ventricle and the pressure reduced is the end diastolic pressure, which is accomplished by having the shunt communicate with the left ventricle so a small volume of blood is released from the left ventricle to reduce the end diastolic pressure. Most preferably, the shunt selectively permits flow when a pressure differential between the left ventricle and another chamber of a heart above a threshold pressure, whereby shunting is prevented during left ventricular systole, or, alternatively, selectively permits flow when a pressure differential between the left ventricle and another chamber of a heart is between a lower threshold and a higher threshold, whereby shunting is again prevented during left ventricular systole. In certain embodiments a semi-passive check-valve is controlled and actuated by an external signal, either using a signal generated by an intra-corporeal electrical battery or an externally coupled energy source. In certain embodiments, the shunt has a pump with an input connected to the left ventricle, or other portion with excessive pressure, and an output connected to a volume of lower pressure. The preferred method of implanting the shunt to effect the present invention is by deploying a tubular element having two ends and a tissue affixation element disposed at each of said ends via a catheter, preferably, the fixation element is a shape retaining metallic material that returns to its original shape as part of the retention aspect of its function. In preferred embodiments of the apparatus, the tubular element is comprised of a biologically inert non-metallic material.

    摘要： A ventricular assist system and a method of implanting the system are disclosed. The system can have a pump, an inflow conduit, an outflow conduit, attachment ring, ring clamp, and a valvular structure. The attachment ring can be attached to the apex of the heart. The valvular structure can have a flexible, one-way valve in a rigid housing. The inflow conduit can be passed through the valvular structure and the attachment ring into a beating heart with minimal loss of blood. Devices such as slitting tool, coring knife, and/or C-clamp and use of the devices can form part of the system and method for implanting the ventricular assist device.
