| 20100185191 | METHOD AND APPARATUS FOR ALIGNING AN ABLATION CATHETER AND A TEMPERATURE PROBE DURING AN ABLATION PROCEDURE - Apparatus for aligning an ablation catheter and a temperature probe relatively for an ablation procedure includes an ablation catheter with a first antenna for ablating tissue at an ablation site in a patient's body and a temperature probe for placement in a body passage having a wall portion adjacent to the ablation site so that a second antenna in the probe is positioned opposite the first antenna. A microwave source provides a pulse modulated microwave signal to one of the antennas and a radiometer is in circuit with the other antenna. A synchronizing device in circuit with the microwave source and the radiometer enables the radiometer to synchronously detect the microwave signal so that the radiometer provides an alignment signal whose strength reflects the degree of alignment of the first and second antennas which signal may be used to control an alignment display. An alignment method using the apparatus is also disclosed. | 07-22-2010 |
| 20090012417 | Dual Mode Intracranial Temperature Detector - Apparatus for detecting thermal radiation emanating from two different intracranial depths in a patient includes a dual-mode transducer having a working surface for placement against a patient's cranium. The transducer includes a first antenna with an aperture adjacent the working surface that first antenna being tuned to a first frequency and producing a first output signal indicative of thermal radiation received within an antenna pattern extending a selected first distance from the working surface and a second antenna having a second aperture adjacent to the working surface within the first aperture The second antenna is tuned to a second frequency and produces a second output signal indicative of thermal radiation received within an antenna pattern extending a selected second distance from the working surface, the second distance being shorter than the first distance. The two output signals are coupled to a receiver/control unit which thereupon monitors and displays the temperature at the two intracranial depths. | 01-08-2009 |
| 20080277388 | In-Line Microwave Warming Apparatus - Microwave warming apparatus includes a housing defining a heating waveguide with a heating cavity. An integral internal electrically conductive ridge projects from one of the longitudinal waveguide walls and extends along the waveguide. A slot having opposite ends extends from the outside through the ridge into the heating cavity, the slot being adapted to receive a cartridge containing a tube so that the tube extends through the slot into the heating cavity. Electromagnetic energy is coupled into the heating waveguide to heat the contents of the tube. A transducer constituted by a first receiving waveguide inside the ridge is adjacent to the slot so that when a cartridge is received in the slot, the transducer can sense the thermal radiation emanating from a segment of the tube and produce a corresponding waveguide-generated signal. A radiometer in the housing is responsive to the waveguide-generated signal and produces a temperature indicating signal. | 11-13-2008 |
