摘要： The catheter device comprises a drive shaft connected to a motor, and a rotor mounted on the drive shaft at the distal end section. The rotor has a frame structure which is formed by a screw-like boundary frame and rotor struts extending radially inwards from the boundary frame. The rotor struts are fastened to the drive shaft by their ends opposite the boundary frame. Between the boundary frame and the drive shaft extends an elastic covering. The frame structure is made of an elastic material such that, after forced compression, the rotor unfolds automatically.

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 When the guide wire is withdrawn from the distal end segment of the catheter, the distal end segment bends back proximally.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 To return the catheter to a straight condition, the rigid guide wire is withdrawn from the catheter, and a guide wire with a resilient J-tip is advanced to the distal end segment of the catheter.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.
