摘要： A tunneling device for creating a pathway in subcutaneous tissue of a person's body. The tunneling device includes a member having two ends, where each of the ends defines an insertion surface that facilitates the insertion of the ends into the subcutaneous tissue of the person's body. The tunneling device includes an interchangeable handle connectable to each of the ends. The handle defines a grasping surface and an opening. The opening is configured to receive either of the ends. The grasping surface enables a user to securely hold the handle with one hand to forcibly move the member through the subcutaneous tissue of the person's body to create the pathway in the subcutaneous tissue, and pull a cable of an implant device through the created pathway .

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： A system, comprising an implantable electrical device adapted for mounting within the body of the patient, and an implantable power unit adapted for mounting within the body of the patient, the power unit having a receiving coil, a power circuit connected to the receiving coil so that power applied to the receiving coil can be transmitted to the implantable device. The system further comprising an external power supply having a transmitting coil adapted for transcutaneous inductive coupling with the receiving coil to define a system having a resonant frequency varying in relation to a distance between the transmitting and receiving coils, a drive circuit operable to apply an alternating current to the transmitting coil at a variable drive pulse width. A control circuit is operable to (i) monitor a parameter related to mutual inductance between the transmitting and receiving coils; and (ii) adjust the variable transmission frequency to a value having a predetermined difference from the resonant frequency, so as to maintain the transmission frequency with a predetermined difference from the resonant frequency. The power circuit further includes a battery and a routing circuit arranged to route power from the receiving coil to the implantable device to the battery or both when power is received through the receiving coil and from the battery to the implantable device when power is not received by the receiving coil, the control circuit being operable to vary the current in the transmitting coil so as to maintain the monitored parameter within the desired range during the charging operation and during operation when the battery is fully charged

摘要： A blood pump is provided which comprises a cross-flow pump head having an elongated generally cylindrical housing portion. The housing portion defines a blood inlet port on a surface thereof and a blood outlet port on an opposite surface thereof. An impeller within the housing portion provides cross-flow of the blood from the inlet port around and/or across the rotational axis of the impeller to the outlet, and a motor is provided for driving the cross-flow pump head. The blood pump may be small enough to permit percutaneous insertion of the pump into a patient's blood vessel, and thus may be utilizable as a left ventricular assist device. To this end, a collapsible polymeric outflow tube is coupled to the blood flow outlet and is adapted for directing the blood from the left ventricle to the aorta through the aortic valve.
