    摘要： An axial-flow blood pump for pumping blood includes a substantially cylindrical outer enclosure. A tubular housing concentric with and located within the outer enclosure has at one end an inlet and at an opposite end an outlet. A motor stator is concentric with and located between the outer enclosure and the tubular housing. An impeller is concentric with and located within the tubular housing. The impeller is suspended in operation by a combination of passive magnetic forces between magnets within the impeller or magnetized regions of the impeller and the motor stator and hydrodynamic thrust forces generated as blood flows between the tubular housing and a plurality of hydrodynamic thrust bearing surfaces located on the impeller. A volute may be in fluid-tight connection with the outlet of the tubular housing for receiving blood in the axial direction and directing blood in a direction normal to the axial direction. The volute has a flow-improving member extending axially from the volute and into and coaxially with the tubular housing.

    摘要： An axial-flow blood pump includes a housing having an inlet and an outlet opposite therefrom. An impeller located within the housing is suspended during operation by magnetic forces between magnets or magnetized regions of the impeller and a motor stator surrounding the housing, and hydrodynamic thrust forces generated by a flow of blood between the housing and a plurality of hydrodynamic thrust bearing surfaces located on the impeller. A volute may be in fluid-tight connection with the outlet of the housing for receiving blood in the axial direction and directing blood in a direction normal to the axial direction. The volute has a flow-improving member extending axially from the volute and into the housing in a coaxial direction of the housing.

    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： One aspect of an intravascular ventricular assist device is an implantable blood pump where the pump includes a housing defining a bore having an axis, one or more rotors disposed within the bore, each rotor including a plurality of magnetic poles, and one or more stators surrounding the bore for providing a magnetic field within the bore to induce rotation of each of the one or more rotors. Another aspect of the invention includes methods of providing cardiac assistance to a mammalian subject as, for example, a human. Further aspects of the invention include rotor bodies having helical channels formed longitudinally along the length of the body of the rotor where each helical channel is formed between peripheral support surface areas facing radially outwardly and extending generally in circumferential directions around the rotational axis of the rotor.
