摘要： An apparatus and method for a centrifugal fluid pump for pumping sensitive biological fluids, which includes (i) an integral impeller and rotor which is entirely supported by an integral combination of permanent magnets and electromagnetic bearings and rotated by an integral motor, (ii) a pump housing and arcuate passages for fluid flow and containment, (iii) a brushless driving motor embedded and integral with the pump housing, (iv) a power supply, and (v) specific electronic sensing of impeller position, velocity or acceleration using a self-sensing method and physiological control algorithm for motor speed and pump performance based upon input from the electromagnetic bearing currents and motor back emf--all fitly joined together to provide efficient, durable and low maintenance pump operation. A specially designed impeller and pump housing provide the mechanism for transport and delivery of fluid through the pump to a pump output port with reduced fluid turbulence.

摘要： An inventive blood pump in accordance with this invention includes a housing that has inlet and outlet ports for receiving and discharging blood. A rotor is positioned in the housing's interior for pumping blood between the housing's inlet and outlet ports, with the rotor being capable of motion in three translational and three rotational axes. An assembly for magnetically suspending and rotating the rotor in a contact-free manner with respect to the housing includes only one electromagnetic bearing that actively controls motion of the rotor with respect to one axis selected from the rotor's three translational and three rotational axes, an electromagnetic motor that actively drives motion of the rotor with respect to one of its three rotational axes, and magnetic bearings for passively controlling motion of the rotor with respect to the remaining four of its translational and rotational axes. The inventive blood pump can also be incorporated into an artificial heart.

摘要： There are disclosed apparatus and methods for replacing a percutaneous cable in connection with a vascular device. In an embodiment, the apparatus includes a distal disconnect coupler, a distal connector portion of the cable configured for removable connection with the distal disconnect coupler, and a connector cap configured for removable connection with the distal disconnect coupler and for tunneling through skin and tissue. In one embodiment, a method of repositioning a percutaneous cable in connection with a vascular device includes providing the cable with a distal disconnect coupler, disconnecting the cable at the distal disconnect coupler, attaching a connector cap to the distal disconnect coupler, removing the percutaneous cable from a first exit site, tunneling the connector cap together with the distal disconnect coupler through skin and tissue to form a new exit site, disconnecting the connector cap, and connecting the cable to the distal disconnect coupler.
