| Number | Title | Issue Date |
| 5370644 | Radiofrequency ablation catheter A cardiac ablation apparatus including a solenoidal antenna, monitoring electrodes, and a coupling network at a distal end of a catheter transmission line, and another coupling network at the proximal end of the catheter transmission line to connect the c... | 12/06/1994 |
| 5257635 | Electrical heating catheter The invention provides a thermal design of a catheter where the active electrode is partially covered by a heat conducting and electrically insulating heat-sink layer for localizing and controlling an electrical heating of tissue and cooling of the active... | 11/02/1993 |
| 5248312 | Liquid metal-filled balloon Liquid metal gallium-filled balloon catheter is connected to a source of heating power. An improved method of hyperthermia and ablation is made possible by ease of insertion and conformity to complex intracavitary geometry by liquid metal. Closeness of ga... | 09/28/1993 |
| 5246438 | Method of radiofrequency ablation A cardiac ablation apparatus including a solenoidal antenna, monitoring electrodes, and a coupling network at a distal end of a catheter transmission line, and another coupling network at the proximal end of the catheter transmission line to connect the c... | 09/21/1993 |
| 5230349 | Electrical heating catheter The invention provides a thermal design of a catheter where the active electrode is partially covered by a heat conducting and electrically insulating heat-sink layer for localizing and controlling an electrical heating of tissue and cooling of the active... | 07/27/1993 |
| 5199437 | Ultrasonic imager The invention provides an intracavitary ultrasonic scanner with a helical scan. Mechanical and electronic steerable array implementations of the helical scan are described. A plastic cover sheath, filled with coupling fluid, covers the probe of the scanne... | 04/06/1993 |
| 4985925 | Active noise reduction system Improvement in active noise reduction based on a negative feedback electro-acoustical system which consists of an Electronic Earplug seated in the concha fossa combining active and passive noise reduction in the quiet zone at the ear, a bilateral transduc... | 01/15/1991 |
| 4945912 | Catheter with radiofrequency heating applicator Radiofrequency (RF) heating applicator, located at the distal end of a coaxial line catheter, produces deeper and more uniform heat dissipation. The active applicator element is a conductor helix fed via the coaxial line. The applicator has provisions for... | 08/07/1990 |
| 4879698 | Piezopolymer actuators Piezopolymer actuator, wound in a bifilar fashion on two pins, is operated in a compressive mode without buckling. In addition to constraining motion of the winding along the surface of the pins, the pins also provide wide area electrical contacts with co... | 11/07/1989 |
