Appl. No.:

10/695110

Inventors:

Paul J. Wang - Saratoga CA, US

Assignee:

New England Medical Center - Boston MA

International Classification:

A61B 18/04

US Classification:

606 32, 606 41, 606 51, 607 99

Abstract:

A medical device, and related method, use epicardial ablators and detectors for intraoperative epicardial approaches to ablation therapy of cardiac conduction pathways. An epicardial gripper is sized to grasp the cardiac circumference or smaller structures on the epicardial surface of the heart. Ablators are disposed on the arms of the gripper for epicardial ablation of cardiac conduction tissue. In another embodiment of the invention, an electrode system includes a flexible, adjustable probe forming a loop for epicardial ablation. Ablators are provided on one or multiple surfaces of the probe for epicardial ablation of cardiac conduction tissue. In yet another embodiment of the invention, an endocardial ablator detection system provides an indicator adjacent an ablator on an endocardial catheter, and a detector on an epicardial probe. The epicardial probe detects signals transmitted by the indicator on the endocardial catheter to localize the position of the endocardial ablator relative to the epicardial surface. The surgeon uses this information for guidance in adjusting the position of the endocardial ablator according to therapeutic objectives of cardiac ablation.

International Classification:

G01S 7/36

US Classification:

342 13, 342 40, 342 59, 342159

Abstract:

A method of classifying radar emitters includes the steps of: (a) receiving pulses from multiple radar emitters; (b) categorizing received pulses based on pulse data descriptors (PDWs); (c) forming clusters of received pulses based on the PDWs; and (d) de-interleaving pulses from the cluster using one of a differential time of arrival (DTOA) histogram technique, a spectrum estimation technique, or a Hough transform technique. Step (a) includes receiving the pulses during a predetermined time interval and storing the received pulses as a snapshot representing the pulses present during the predetermined time interval.

International Classification:

A61B 5/00

US Classification:

600573, 604 73, 604 74, 604 75, 604315, 604316

Abstract:

The invention is an apparatus () for treating inverted nipples and/or the collection of NAF. The invention includes an assembly which creates an airtight seal upon attachment to at least an areola () of an inverted nipple () and by rotation of a part thereof draws a partial vacuum to apply an outward force to the nipple; and a syringe () including a curved longitudinal axis (), the syringe being carried by the assembly and being in fluid communication with a chamber () of the assembly upon attachment of the assembly to at least an areola of an inverted nipple, the syringe including a plunger () which is sealed against an inner surface () of the syringe and is rotatable to move along the longitudinal axis relative to the chamber which moves the plunger within a syringe body to expel air from the syringe body away from the chamber upon rotation of the plunger in a first direction and to aspirate air from the chamber upon attachment of the apparatus to the breast surrounding the nipple upon rotation in a second direction opposite to the first direction to create a partial vacuum within the chamber to evert the nipple.

International Classification:

G01S 7/40

US Classification:

342 13, 342 90, 342195

Abstract:

A method of classifying radar emitters includes the steps of: (a) receiving pulses from multiple radar emitters over a plurality of consecutive first time intervals; (b) identifying pulses in each of the plurality of consecutive first time intervals corresponding to one or more first pulse trains using a first algorithm and de-interleaving the identified pulses from the plurality of first time intervals; (c) associating received pulses not identified and de-interleaved using the first algorithm with a plurality of consecutive second time intervals; and (d) identifying further pulses in each of the plurality of consecutive second time intervals corresponding to one or more second pulse trains using a second algorithm different from the first algorithm and de-interleaving the identified further pulses from the pulses associated with the plurality of consecutive second time intervals. Each consecutive second time interval is formed from two or more consecutive first time intervals.

International Classification:

A61B 18/14
A61B 18/02

US Classification:

606 41, 606 20

Abstract:

The system of the preferred embodiments includes a first rotational element, a second rotational element, and a therapeutic source coupled to the rotational elements. The system permits simultaneous attachment to and movement around a surface of tissue, preferably during an ablation procedure (either during lesion creation or between lesion creation events), or during any other suitable procedure. The therapeutic source functions to translate along the path of tissue and deliver therapy as the first and second rotational elements rotate and roll along the path of tissue. The therapeutic source preferably delivers contiguous doses of therapy along the path of tissue. The system is preferably designed for delivering therapy to tissue and, more specifically, for delivering therapy to cardiac tissue. The system, however, may be alternatively used in any suitable environment and for any suitable reason.
