Publication number: 20120150178Abstract: An integrated catheter assembly for enabling diverse endoscopic in situ therapies. The assembly includes a catheter with an irrigation fluid lumen, a distal electrode tip portion that acts as a hemostat, and a cutting wire for making incisions in or ablating tissue. A cutting wire hub provides a sealing entrance for a cutting wire. An operator enables the physician to displace the cutting wire between extended and retracted positions. The cutting wire and electrode are electrically isolated. In addition, the catheter assembly may include a planar tip which, when extended outside the distal end of the assembly, assumes a substantially flat unbiased configuration for use. The apparatus of the present invention allows the physician to make incisions in or ablate tissue using electrosurgery, irrigate tissue, and cauterize or coagulate tissue without having to remove the apparatus from the working channel of the endoscope.Type: ApplicationFiled: February 17, 2012Publication date: June 14, 2012Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Russell Francis Durgin, Stephen F.

Publication number: 20060069306Abstract: The present invention is an integrated and automated irrigation and aspiration system for use in an endoscopic imaging system. The system provides for the automated cleaning of poorly prepared patients during a colonoscopy procedure as well as automated cleaning of an imaging system of an endoscope. The invention analyzes images obtained from an image sensor to detect the presence of an obstructed field of view, whereupon a wash routine is initiated to remove the obstruction. The wash routine may be adjusted in accordance with environmental conditions within the patient that are sensed by one or more sensors within the endoscope. In another embodiment, insufflation is automatically controlled to inflate a patient's colon as a function of one or more sensor readings obtained from one or more environmental sensor(s) on the endoscope.Type: ApplicationFiled: September 30, 2004Publication date: March 30, 2006Inventors: Michael Banik, Lucien Couvillon, Anh Nguyen, William Stahley

Patent number: 6856811Abstract: A portable communication network comprises plural portable communications units, each providing a unit code identifier, a wave energy transceiver, preferably using RF energy which is enabled for direct communication with any other of the communications units over a limited range, a device for assigning a target code to each signal transmission, a device for detecting the target code in each signal reception, a device for processing a received signal when the target code of the received signal equals the unit code, and a device for retransmitting a received signal when the target code of the received signal differs from the unit code. In this manner, through signal repeating, communication is enabled between any two of the communications units when their separation is greater then the limited range. Automatic routing through the communication network is established between two members of the network. Alternate routes are established as background tasks to be switched in if the current route is interrupted.Type: GrantFiled: February 1, 2002Date of Patent: February 15, 2005Inventors: Warren L.

Patent number: 6771821Abstract: This invention is directed to the transferring of information in two-dimensional form. The form may be an image or may be printed word. The information is converted to a digital bit map. The bit map information is compressed by any compression technique (JPEG, MPEG, WAVELET, FRACTAL, etc.) and at the same time a first forward error-correcting code is generated of the bit map. The compressed information and the first forward error-correction code is formed into a data packet. These packets are transmitted with a second forward error-correcting code of the packet in order to correct any transmission errors. After correcting any transmission errors found at the receiving end as a result of the second forward error correction code, the data stream is decompressed, and an image bit map is regenerated. The first forward error-correction code is applied, and the bit map is corrected.Type: GrantFiled: November 22, 1999Date of Patent: August 3, 2004Assignee: Keystone InternationalInventor: William Stahley

Patent number: 5157408Abstract: A radio system for determining the range and bearing of mobile equipment, such as an aircraft, relative to reference equipment such as an aircraft carrier, with low probability of interception (LPI). The aircraft remains equipped with high power range and bearing determination equipment, such as TACAN equipment. Reference equipment transmits a LPI beacon, such as a pseudo noise code spread spectrum signal through a rotating beam antenna to amplitude modulate the beacon as a function of antenna orientation. The PN code is inverted as the antenna passes through a reference bearing. Mobile LPI equipment determines bearing and generates a high power signal, such as an emulated TACAN beacon signal. High power range and bearing equipment extracts bearing information from the emulated signal and display it. Range can be determined in a cooperative mode. Mobile LPI equipment transmits a LPI interrogation signal. Reference LPI equipment returns a LPI reply signal.Type: GrantFiled: May 25, 1990Date of Patent: October 20, 1992Assignee: NavCom Defence Electronics, Inc.Inventors: Kenneth M.
