    摘要: A system and method for heating cells surrounding metallic implants in living beings. The system includes a metallic implant within the living being, surrounded by the cells to be heated, an induction coil having an aperture sufficiently large to accommodate a portion of the living being containing the metallic implant, and an RF generator coupled to the coil to apply an electric RF signal thereto, the RF signal ranging in frequency from 10 kilohertz to 10 megahertz. The metallic implant is inductively heatable by the application of the RF signal to the induction coil.

    摘要: The catheter device comprises a motor located at the proximal end of the catheter device and a drive shaft, extending from the proximal end section to the distal end section of the catheter device, for driving a rotating element located at the distal end of the catheter device. The catheter device also comprises a hose-like catheter body which encompasses the drive shaft and extends from the proximal end section to the distal end section of the catheter device. At the proximal end of the catheter device, the drive shaft is connected to a motor by a clutch. The clutch is a magnetic clutch with a proximal and a distal magnet unit. The proximal magnet unit is connected to the motor and the distal magnet unit to the drive shaft. The distal magnet unit is mounted fluid-tight in a clutch housing.

    摘要: A cardiac function variation evaluation apparatus includes: a continuous flow type auxiliary artificial heart 20 connected to a ventricle (10A); a pressure sensor 30 for detecting ventricle (10A) internal pressure; and means (a personal computer 40) for evaluating contractile variation of the ventricle, to which the auxiliary artificial heart 20 is connected, based on internal area APMp of a closed-loop of a relationship between the ventricle internal pressure detected by the pressure sensor 30 and a consumption power of the auxiliary artificial heart 20. Thus, the contractile variation of the ventricle, to which an auxiliary artificial heart is connected, can be continuously evaluated not by use of an ultrasonic echo apparatus or a conductance catheter but by use of a non-invasive method.

    摘要: Method and apparatus for fragmentation of a lung embolus. The apparatus includes a catheter that is introduced over a guide wire to the site of the lung embolism in the vascular system of a patient. When the guide wire is withdrawn from the distal end segment of the catheter, the distal end segment bends back proximally. An opening in the bend of the catheter is in line with the central axis of the catheter when the distal end segment is in a curved configuration. The guide wire is then advanced to extend distally from the catheter opening past the embolism and stabilize the longitudinal position of the catheter in the blood vessel. The apparatus also includes a thread for pulling the bent distal end segment into a generally oval-shaped loop condition and stabilizing the loop about the embolism. The looped catheter is then rotated and moved longitudinally back and forth for mechanically destroying the embolism. To return the catheter to a straight condition, the rigid guide wire is withdrawn from the catheter, and a guide wire with a resilient J-tip is advanced to the distal end segment of the catheter. The J-tip guide wire follows the catheter past the catheter opening, thereby straightening the catheter for removal from the body. The apparatus optionally includes a handle or motor positioned at the proximal end of the apparatus.
