Patent number: 11324395Abstract: An endoscopic imaging system includes a reusable control cabinet having a number of actuators that control the orientation of a lightweight endoscope that is connectable thereto. The endoscope is used with a single patient and is then disposed. The endoscope includes an illumination mechanism, an image sensor and an elongate shaft having one or more lumens located therein. A polymeric articulation joint at the distal end of the endoscope allows the distal end to be oriented by the control cabinet. The endoscope is coated with a hydrophilic coating that reduces its coefficient of friction and because it is lightweight, requires less force to advance it to a desired location within a patient.Type: GrantFiled: November 24, 2020Date of Patent: May 10, 2022Assignee: Boston Scientific Scimed, Inc.Inventors: Michael S. Banik, Dennis R. Boulais, Lucien A. Couvillon, Albert C. C. Chin, Ian W. Hunter

Patent number: 7947059Abstract: A medical device such as a tube or a balloon including wall structure with multiple layers. The wall structure can distribute stress, resulting in reduced defect propagation and failure.Type: GrantFiled: March 2, 2001Date of Patent: May 24, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Albert C. C. Chin, John Jianhua Chen, Yiqun Wang, David W. Lodin, Lixiao Wang, Ronald A. Sahatjian, Ismail Guler, Robert Burgmeier

Patent number: 6977103Abstract: An inflatable medical balloon comprises a polymer matrix material and a plurality of fibers distributed in the matrix material. The plurality of fibers operatively adhere to the matrix material and provide reinforcement thereof. The fibers may be parallel or angularly oriented relative to the longitudinal balloon axis, and may be helically disposed thereabout. The fibers may be composed of material which has a greater tensile strength than the matrix material. The fibers may be microfibers formed by phase separation of a melt blend material during extrusion or polymer cores coextruded with the matrix material and surrounded thereby. The balloon may be formed of alternating layers of fiber-free polymer and layers of fiber-containing polymer.Type: GrantFiled: June 20, 2001Date of Patent: December 20, 2005Assignee: Boston Scientific SciMed, Inc.Inventors: John Jianhua Chen, Lixiao Wang, Yiqun Wang, Albert C.

Patent number: 6905743Abstract: A medical balloon composed of a micro-composite material which provides for radial expansion of a balloon to a predetermined extent, but which has minimal longitudinal growing during balloon inflation. The micro-composite material includes a fibril component, a matrix component, and optionally, a compatibilizer. The fibril component may preferably be liquid crystal polymer fibers randomly scattered through out the balloon material. The liquid crystal polymers are created by extrusion at high speed. An alternative fibril component may be a PET fibers which are uniformly spaced about the balloon material and extend through out the length of the balloon material tube.Type: GrantFiled: October 25, 2000Date of Patent: June 14, 2005Assignee: Boston Scientific SciMed, Inc.Inventors: John Jianhua Chen, Lixiao Wang, Yiqun Wang, Albert C.

Publication number: 20020038140Abstract: A stent delivery system comprising a catheter. The catheter including a stent mounting region and a stent disposed thereabout. The stent having a distal end and a proximal end, and an unexpanded state and an expanded state. At least one stent retaining sleeve, having a first end and a second end, wherein the first end overlays an end of the stent when the stent is in the unexpanded state. The second end engaged to at least a portion of the catheter adjacent to the stent mounting region. The stent retaining sleeve(s) comprising a first material and at least one substantially longitudinally oriented fiber of a second material. The first material having a predetermined tensile modulus and the second material having a predetermined tensile modulus, wherein the predetermined tensile modulus of the second material is greater than that of the first material.Type: ApplicationFiled: December 29, 2000Publication date: March 28, 2002Inventors: Dachuan Yang, Paul J. Miller, Jan D. Seppala, Albert C. C. Chin, John Jianhua Chen, Daniel J. Horn
