Patent number: 9566069Abstract: A ligating instrument is provided, including an elongate member, such as a tube, having a lumen, the elongate member extending from a proximal actuator member to a distal ligating band dispenser. A pull line may extend through the lumen of the elongate member, with a proximal end of the pull line connected to the actuator member and a distal end of the pull line connected to the ligating band dispenser, wherein actuation of the actuator member draws the pull line in a proximal direction through the elongate member to deploy the ligating bands. The ligating band dispenser may be adapted to be mounted on the distal tip of an endoscope, and the elongate member may be adapted to be positioned outside of the endoscope from the ligating band dispenser to the actuator member.Type: GrantFiled: July 23, 2014Date of Patent: February 14, 2017Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventor: M. Kevin Richardson

Patent number: 9215970Abstract: A steerable imaging catheter is provided, including an elongated catheter tube, at least one steering cable extending along the catheter tube to control the movement of the distal end thereof, and a fiber optic cable extending along the catheter tube. The fiber optic cable transmits illumination light from its proximal end to its distal end and transmits an image from its distal end to its proximal end. In one embodiment, two or more steering cables are used, and the catheter tube is configured to have greater flexibility near its distal end than its proximal end so as to concentrate the movement (flexing) of the catheter tube at its distal end. The use of two or more steering cables, together with the catheter tube having varying flexibility, permit better control of the distal end of the catheter tube while reducing undue twisting of the remainder of the catheter tube.Type: GrantFiled: October 16, 2013Date of Patent: December 22, 2015Assignee: Boston Scientific Scimed, Inc.Inventors: Michael P. Boutillette, David Micky Graves, M. Kevin Richardson, David I. Freed, Paul M. Scopton

Publication number: 20080132990Abstract: A stent delivery system includes a catheter shaft defining two lumens, for respectively receiving a guidewire and a fiber optic cable having a viewing capability. Specifically, the fiber optic cable has a first (e.g., proximal) end and a second (e.g., distal) end, and is adapted for transmitting illumination light from its first end to its second end while transmitting an image from its second end to its first end. The system further includes a stent positioned over the catheter shaft, and may also include means for deploying the stent. The stent may be of a self-expanding type or of an inflation type.

Publication number: 20040098105Abstract: Method for draining pseudocysts and stent delivery system for use therein. In one embodiment, the system comprises an inner catheter provided with a pair of longitudinal lumens. A guide wire is slidably disposed in one lumen, and a retractable needle is slidably disposed in the other lumen. A self-expandable stent is coaxially mounted around the inner catheter near its distal end, and an outer catheter is coaxially mounted around the inner catheter and the stent, the outer catheter being adapted for axial movement relative to the inner catheter and being dimensioned to maintain the stent in a compressed state. In use, an endoscope is intraorally introduced into a patient's stomach, and the distal end of the system is inserted therethrough. The needle is advanced to form perforations in the stomach and pseudocyst. The inner catheter is then inserted through the perforations, and the outer catheter is retracted, allowing the stent to expand and interconnect the stomach and pseudocyst.Type: ApplicationFiled: September 15, 2003Publication date: May 20, 2004Inventors: Jonathan S.
