摘要： PROBLEM TO BE SOLVED: To provide a pump in which an impeller rotates on a wear-free hydrodynamic bearing and magnetic bearing, and the impeller in contact with only blood within the pump can move the blood from a pump inlet to a pump outlet.SOLUTION: A rotary blood pump includes a casing defining a pumping chamber. The pumping chamber has a blood inlet and a tangential blood outlet. One or more motor stators are provided outside of the pumping chamber. A rotatable impeller is within the pumping chamber and is adapted to cause blood entering the pumping chamber to move to the blood outlet. The impeller has one or more magnetic regions. The impeller is radially constrained by one or more magnetic coupling and is axially constrained by one or more hydrodynamic thrust bearing surfaces 34 on the impeller.

摘要： A connector for connecting an implant device to tissue of a person's body. The connector including a frame having first and second arms. The first and second arms define an opening, where at least a portion of the implant device is inserted through the opening. After insertion, an additional securing member is connected to the frame. The securing member is adapted to receive at least one suture to secure the frame to the tissue. The connector includes an adjuster that is movably connected to the first and second arms, where the adjuster is operable to cause the first and second arms to move toward each other and engage the implant device.

摘要： A rotary blood pump (10) is disclosed. The rotary pump comprises a housing (1) defining a pumping chamber with upper and lower interior surfaces and having a blood inlet (11) and a tangential blood outlet (13). The rotary pump further includes a rotatable impeller (20) within said pumping chamber and adapted to increase blood pressure within said pumping chamber to cause blood to move to said blood outlet, said impeller has at least one upper surface area spaced by a gap from said upper interior surface of said pumping chamber, said upper surface area having a first tapered region and a second tapered region, said first tapered region of said upper surface area having a leading portion and a trailing portion such that said gap decreases from said leading portion to said trailing portion to create a hydrodynamic thrust load to bias said impeller axially away from said upper interior surface of said housing when said impeller is rotating. The second tapered region of said upper surface area has a leading portion adjacent said trailing portion of said first tapered region and having a trailing portion such that said gap increases from said leading portion of said second tapered region to its trailing portion to relieve hydrodynamic pressure on blood when said impeller is rotating, whereby blood traverses said upper surface area without hemolysis.
