Wide-Aperture Catheter-Based Microwave Cardiac Ablation Antenna

View page
US Patent:
6699241, Mar 2, 2004
Filed:
Aug 8, 2001
Appl. No.:
09/924927
Inventors:
Carey M. Rappaport - Wellesley MA
Paul Wang - Chestnut Hill MA
Zeji Gu - Lexington MA
Assignee:
Northeastern University - Boston MA
International Classification:
A61B 1818
US Classification:
606 33, 607100, 607101, 607156, 606 41
Abstract:
A catheter-based microwave antenna cardiac ablation applicator has been developed which unlike previously-developed ablation catheters, forms a wide aperture that produces a large heating pattern. The antenna comprises a spiral antenna connected to the center conductor of a coaxial line, and which is insulated from blood and tissue by a non-conductive fluid filled balloon. The antenna can be furled inside a catheter for transluminal guiding. Once in place at the cardiac target, the balloon is inflated, and the coiled spiral antenna is ejected into the inflated balloon. The wide aperture antenna generates a ring-shaped power pattern. The heat generated from this deposited power is conducted through a volume larger than the spiral diameter, ablating diseased tissue. The resultant lesion profile is both wider and deeper than that of either conventionally-used RF catheter-based ablation electrodes, or that of other microwave applicators, and provides greater heating accuracy and controllability.

Multiple Wavelength Microwave-Enhanced Infrared Thermography

View page
US Patent:
6753529, Jun 22, 2004
Filed:
Jul 2, 2002
Appl. No.:
10/189340
Inventors:
Charles A. DiMarzio - Cambridge MA
Carey M. Rappaport - Wellesley MA
Taner Oktar - Boston MA
Gerhard O. Sauermann - Lexington MA
Assignee:
Northeastern University - Boston MA
International Classification:
G01N 2500
US Classification:
2503416
Abstract:
A microwave-enhanced infrared thermography technique for detecting buried objects exploits varying phase shifts experienced by different-frequency microwave signals reflected from objects back toward the surface, the phase shifts resulting in different interference patterns and therefore different temperature distribution patterns near the surface. Respective infrared images of an area are captured prior to microwave heating, after a first heating with a first frequency, and after heating with a second frequency different from the first. Pairs of the images are subtracted to form temperature rise images showing patterns of temperature rise in the two cycles, and the temperature rise images are subtracted to form a difference image which is analyzed to identify characteristics indicating the presence of buried objects.

Roaming Mobile Sensor Platform For Collecting Geo-Referenced Data And Creating Thematic Maps

View page
US Patent:
2013001, Jan 17, 2013
Filed:
Mar 21, 2011
Appl. No.:
13/636112
Inventors:
Ralf Birken - Somerville MA,
Ming-Liang Wang - Melrose MA,
Carey M. Rappaport - Wellesley MA,
Gregory J. McDaniels - Lexington MA,
International Classification:
G01C 21/32
G01S 13/89
US Classification:
701409, 701514
Abstract:
A roaming sensor system collects data on the condition of roads and bridge decks and identifies and maps defects, including cracks, potholes, debonding, tracking, delamination, surface ice, surface water, and rebar corrosion. Data are collected by a vehicle or a fleet of vehicles driven at normal traffic speeds. The vehicle is outfitted with sensors that collect data using acoustic surface waves, ground penetrating radar, mm wave surface radar, and/or video images. The data are transmitted to a control center for analysis and distribution.

Doubly Shaped Reflector Transmitting Antenna For Millimeter-Wave Security Scanning System

View page
US Patent:
2014005, Feb 27, 2014
Filed:
Aug 20, 2013
Appl. No.:
13/971430
Inventors:
Carey Rappaport - Wellesley MA,
Assignee:
Northeastern University - Boston MA
International Classification:
H01Q 15/16
US Classification:
343840
Abstract:
In some aspects, the disclosure is directed methods and systems for focusing millimeter-wave radiation to a line for scanning a target object. A source may provide millimeter-wave radiation, and may include a substantially point source. A reflector may include a surface with an elliptical cross-section within a first plane and a curved cross-section within a second plane perpendicular to the first plane. The curved cross-section may be shaped differently from the elliptical cross-section within their respective planes. The surface may focus the millimeter-wave radiation from the source at a line on a third plane parallel to or coinciding with the second plane. The line may be located at an approximate location where a target object is expected to be positioned. At least one sensor may measure the millimeter-wave radiation from the reflector scattered off the target object.

High Aperture Efficiency, Wide Angle Scanning Reflector Antenna

View page
US Patent:
5140337, Aug 18, 1992
Filed:
May 3, 1991
Appl. No.:
7/700083
Inventors:
Carey M. Rappaport - Boston MA
Assignee:
Northeastern University - Boston MA
International Classification:
H01Q 1912
US Classification:
343840
Abstract:
A microwave single reflector antenna is provided with a large field of view and high aperture efficiency. The antenna exhibits good lateral scanning while preserving excellent focusing capabilities. The high aperture efficiency yields higher antenna performance than a conventional reflector antenna of the same size, or the same performance as a conventional scanning antena of larger size. The antenna has an improved surface configuration defined by a fourth-order profile extended into a three-dimensional focusing surface.

Balloon Angioplasty Device

US Patent:
5470352, Nov 28, 1995
Filed:
Oct 29, 1993
Appl. No.:
8/145878
Inventors:
Carey M. Rappaport - Newton MA
Assignee:
Northeastern University - Boston MA
International Classification:
A61B 1736
A61N 502
A61M 2510
US Classification:
607101
Abstract:
A balloon angioplasty device includes a microwave antenna, a catheter and a transmission line disposed through the catheter and coupled to the antenna. The device further includes a balloon coupled to the catheter and a mode filter disposed about the antenna.

High Aperture-Efficient, Wide-Angle Scanning Offset Reflector Antenna

View page
US Patent:
5175562, Dec 29, 1992
Filed:
May 6, 1991
Appl. No.:
7/695738
Inventors:
Carey M. Rappaport - Boston MA
Assignee:
Northeastern University - Boston MA
International Classification:
H01Q 1912
US Classification:
343840
Abstract:
A single offset reflector antenna is disclosed which provides. +-. 30. degree. of horizontal scanning and 0. degree. to +15. degree. of vertical scanning without aperture blockage, while maintaining high aperture efficiency, and 0. degree. to -30. degree. of vertical scanning with moderate aperture blockage. The sufrace of the reflector antenna is described by a sixth order polynomial equation. Curvature of the horizontal cross-section of the surface taken through its center is determined by a fourth order even polynomial expression with coefficients that are found by a numerical minimization technique. Further terms, including terms of up to sixth order and their associated coefficients obtained by the numerical minimization technique, define the curvature of the vertical cross-sections of the surface to yield a three-dimensional unitary reflecting surface.
