Publication number: 20100176535Abstract: A low profile, short, tapered distal tip catheter and methods for its manufacture are provided. The catheter tip is configured to have a taper over a relatively short length resulting in a low profile that is useful when navigating the catheter tip into tight passages such as the Papilla of Vater. The configuration of the tip and process for making it can be employed in any medical catheter but are found to be most useful in a multilumen papillotome catheter used in biliary procedures.Type: ApplicationFiled: December 4, 2009Publication date: July 15, 2010Applicant: Conmed Endoscopic Technologies, Inc.Inventor: Steven L. Jacques

Patent number: 7632241Abstract: A multi-lumen biliary catheter in which at least one of the lumens (14, 16) has a side opening port (24, 26) configured to guide a guidewire (32) out of that port at an angle to the longitudinal axis of the catheter. Radiopaque marker bands (34) having different lengths are placed on the distal end of the catheter adjacent the distal openings to facilitate fluoroscopic identification of the distal end orientation in the biliary tract.Type: GrantFiled: May 17, 2001Date of Patent: December 15, 2009Assignee: Conmed Endoscopic Technologies, Inc.Inventors: Isaac Raijman, John E. Dimitriou

Patent number: 7481800Abstract: A triple lumen stone balloon catheter (1) having a tapered distal end (9). A lumen (24) dedicated to transmitting contrast media is dimensioned and adapted to conform to the shape of a kidney in a main shaft of the catheter and conform to the shape of a crescent in a distal end of the catheter. The geometric shaping of the contrast media lumen (24) enables wall thickness to be maintained within acceptable ranges to sustain desirable mechanical characteristics while allowing for enhanced contrast media flow. A method for employing the balloon catheter (1) is also disclosed.Type: GrantFiled: February 2, 2001Date of Patent: January 27, 2009Assignee: ConMed Endoscopic TechnologiesInventor: Steven L. Jacques

Publication number: 20070265493Abstract: The present invention provides a ligating band dispenser that is mounted on the distal end of an endoscope. The ligator is configured to deliver multiple ligating bands to a plurality of internal sites in a patient. The ligating bands are carried on a tubular band carrier member that is retractable relative to the distal end of the endoscope in order to preserve visibility through the endoscope during navigation, then extendable to define a suction chamber for tissue aspiration during band delivery. A tubular band driver member is slidable over the band carrier member and engages bands individually to push them off the distal end of the band carrier and onto a selected treatment site. A single-hand operated control handle for selectively operating the extension of the band carrier and movement of the band driver to release a band is also provided and is slidably and removably mounted to the endoscope shaft.Type: ApplicationFiled: March 12, 2007Publication date: November 15, 2007Applicant: CONMED ENDOSCOPIC TECHNOLOGIES, INC.Inventors: Christopher Zirps, Timothy Membrino, Scott Reed, Ernest Corrao, Stephen Maguire, Eric Mears, David Copeland, John Murphy, Joseph Logan, Sean Silva, Stephen Yardan
