Patent number: 5716389Abstract: The catheter sensing and ablation arrangement allows location and cardiac abalation on a patient. The arrangement includes an electrically nonconductive catheter body, with a guide-wire lumen. The guidewire is electrically conductive, and, when the guidewire is assembled with the catheter, extends through the lumen, and is slideable therein. The guidewire has an enlarged distal end which, when retracted, blocks the guidewire lumen. The distal end of the catheter body has an exposed first electrode, which is connected to a terminal located near the proximal end. An action potential sensor is adapted for, in a sensing mode of operation, coupling to the proximal end of the guide wire and to the electrical terminal, for sensing action potentials appearing between the enlarged end of the guide wire and the first electrode, so the end of the guide wire may be moved to a cardiac location identifiable by the action potentials.Type: GrantFiled: November 13, 1995Date of Patent: February 10, 1998Inventors: Paul Walinsky, Arnold Jack Greenspon, Arye Rosen

Patent number: 5421727Abstract: Dental or endodontic instruments such as drills, files, rasps, broaches, reamers, and the like are arranged to allow radiation of electromagnetic energy into a man-made or natural cavity in the tooth under treatment. The energy may be in the form of microwave or radio-frequency (RF) radiation. The energy raises the temperature of the surrounding tooth material, which tends to disinfect the material as a direct consequence of the temperature. Also, if a disinfectant material is additionally introduced into the tooth cavity, the temperature of the disinfectant material itself may be raised, which enhances its activity. In the particular application to the removal of degenerated pulp, the instrument may be introduced, and electrical or electromagnetic power applied to coagulate the pulp about the instrument, allowing more complete removal of the pulp. The dental instrument may be used with an RF energy delivery system for application of particular amounts of energy per unit time (power).Type: GrantFiled: June 7, 1993Date of Patent: June 6, 1995Inventors: Barry H. Stevens, Arye Rosen, Kevin W. Choi

Patent number: 5295955Abstract: Fatty tissue involved in a liposuction procedure is treated with microwave energy (also known as RF). In a particular embodiment of the invention, the microwave energy is applied by means of a catheter including a suction lumen, an electromagnetic transmission line, and an antenna coupled to the distal end of the transmission line. A microwave generator coupled to the distal end of the transmission line causes radiation from the antenna into the fatty tissue adjacent to the distal suction port of the suction lumen, which tissue is thereby heated and softened. The softened fatty tissue is more readily detached from the adjacent tissue than in the absence of heat, and less mechanical force is required for removal. In another embodiment of the invention, the transmission line is formed so that the electromagnetic field extends into the suction lumen, so that the fatty tissue being removed therethrough continues to be heated.Type: GrantFiled: February 14, 1992Date of Patent: March 22, 1994Assignee: AMT, Inc.Inventors: Daniella Rosen, Arye Rosen

Patent number: 5129396Abstract: A multipurpose catheter apparatus for microwave aided balloon angioplasty includes a balloon capable of being filled with a lossy dielectric liquid, and bearing a metallization pattern. The catheter includes an electromagnetic transmission line. Radio frequency energy applied to the proximal end of the electromagnetic transmission line is radiated by an antenna within the balloon. The metallization pattern causes a portion of the energy applied to the proximal end of the transmission line to be reflected, which affects a characteristic such as impedance, return loss or time of reflection. A measurement apparatus measures the characteristic, and the distention of the balloon is determined from the measured characteristic. A guide filament may extend through the transmission line.Type: GrantFiled: September 18, 1990Date of Patent: July 14, 1992Inventors: Arye Rosen, Paul Walinsky

Patent number: 5099214Abstract: A waveguide having walls defining an opening. An optically transmissive aperture in one wall allows light from an optical illumination source such as a laser diode array to illuminate the opening in which is located a semiconductor slab positioned to be illuminated. When the array illuminates the slab, the propagation characteristics (phase velocity and attenuation constant) of the waveguide changes. A continuous wave signal passing through the waveguide is thus attenuated and phase shifted. The laser array may be pulsed on and off while still maintaining the altered propagation constant.Type: GrantFiled: September 27, 1989Date of Patent: March 24, 1992Assignee: General Electric CompanyInventors: Arye Rosen, Paul J. Stabile, Walter M. Janton
