An access device for a heart chamber, a removable hemostatic valve unit, and a system including a cardiac assist unit are disclosed. In examples, the access device) includes an apical base plate and a sealing unit configured to provide a separation of a wet zone from a heart chamber and a dry zone with a gaseous environment outside of said heart chamber inside a patient body at the same time.

Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.

Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

A smart cardiac assist device which may aid in ventricular recovery. The device proactively assists the left and the right ventricular chambers to contract and relax better. The device includes a plurality of sensors to understand the native cardiac function in real time and assist the heart as per its requirement and support required in real time.

A first drive unit, in a state where a top end of a tubular joint is interposed into a chest of a target person and is located at a lower heart part, pushes a diaphragm out from the top end of the tubular joint while pressing a gas into the diaphragm, and simultaneously causes the diaphragm to start flexing to cover and wrap the lower heart part, and then stops pressing the gas into the diaphragm at a time point where compression balloons are positioned at atriums and ventricles of a heart, respectively; and second drive units support a pumping function of the heart by alternately repeating an ejecting operation to fill each of the compression balloons with a fluid and cause each compression balloon to expand and an absorbing operation to cause each compression balloon to discharge the fluid and contract.
