Patent number: 8579881Abstract: Catheter for use in biliary procedures, including a shaft having a proximal end and a distal end. A guidewire lumen is carried by the shaft extending from a location proximal the distal end of the shaft to a location proximate the distal end of the shaft. An opening is included for accessing the guidewire lumen from a location exterior the catheter shaft located distal the proximal end of the shaft. The guidewire lumen may be formed integral the catheter shaft. The catheter may be used in rapid exchange catheter procedures. The catheter may further include a port and channel design including a first opening into the guidewire lumen located proximal the distal end of the shaft, a second opening located proximal the first opening, and a channel extending longitudinally between the first opening and the second opening.Type: GrantFiled: February 28, 2011Date of Patent: November 12, 2013Assignee: Boston Scientific CorporationInventors: Mark Agro, Joseph Levendusky, Charles Warich, Ronald Paille

Patent number: 6436056Abstract: Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include medical guidewires, catheters, and driveshafts.Type: GrantFiled: July 13, 1998Date of Patent: August 20, 2002Assignee: Boston Scientific CorporationInventors: James C. Wang, Albert Chin, James B. Daigle, Douglas J. Daniels, Richard M. Demello, John F. Hartnett, Robert E. Reid, Christopher A. Rowland, Charles Warich, Thomas A. Svatek

Patent number: 6142957Abstract: In an aspect, the invention relates to an instrument for obtaining tissue samples from a site deep within the body. The instrument has an elongated proximal portion that is constructed to follow a long, torturous path to the site and has a distal end constructed to sever and remove a tissue sample from the body, including tissue specimens, polyps or the like. The improvement includes that the instrument is constructed to take multiple biopsy samples without being withdrawn from the body. The instrument includes a tissue sample retractor. The retractor is axially movable between an extended tissue-engaging position and a retracted position. There is an open passage into which the retractor moves when moving from the extended to the retracted position. The retractor has a distal end portion constructed to engage tissue and apply axial transporting force thereto while moving from the extended to the retracted position.Type: GrantFiled: January 27, 1997Date of Patent: November 7, 2000Assignee: Boston Scientific CorporationInventors: Bruce H. Diamond, Donald E. Robinson, Alyssa J. Dassa, Charles Warich

A guide wire lumen is carried by the shaft extending from a location proximal the distal end of the shaft to a location proximate the distal end of the shaft. A channel extending longitudinally between a first end and a second end is included for accessing the guide wire lumen from a location exterior the catheter shaft located distal the proximal end of the shaft. The catheter may be used in rapid exchange catheter procedures. The channel may be U-shaped, containing the guide wire yet allowing radial removal of the guide wire from the channel. The catheter may also be part of a device including an endoscope exchange sheath for constraining guide wire movement to the catheter channel while inside a large endoscope working channel.Type: GrantFiled: September 9, 1997Date of Patent: December 28, 1999Assignee: Boston Scientific CorporationInventors: Mark Agro, Charles Warich, Gary McAlister, Gordon Nelson, Daniel Brillo, Ronald Paille
