Publication number: 20180036032Abstract: A medical device assembly for incising a stenosis in a blood vessel which includes an incising device, a tubular sheath, and a catheter having an inflatable balloon mounted thereon. The incising device includes a self-expanding scaffold having a plurality of cutting elements projecting radially outward therefrom, and an elongate member extending proximally from the self-expanding scaffold to be manipulated by a user. The self-expanding scaffold is positionable in the lumen of the sheath in a contracted configuration and deployed out of the lumen of the sheath to permit the self-expanding scaffold to expand to an expanded configuration. The inflatable balloon of the catheter is configured to be advanced distally into an interior of the self-expanding scaffold through a proximal opening of the self-expanding scaffold, and inflation of the inflatable balloon urges the cutting elements radially outward to incise a stenosis.Type: ApplicationFiled: September 13, 2017Publication date: February 8, 2018Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: STEVEN SPENCER, RICHARD GUNDERSON

Patent number: 9194734Abstract: A liquid replenishment system includes a reservoir, a first temperature sensor positioned in the reservoir at a full level, a second temperature sensor positioned in the reservoir at an add level, and a controller. The controller is connected to both the first and second sensors. The controller receives temperature signals from the first and second temperature sensors at first and second times. The controller sends an add liquid signal if temperature sensed by the first temperature sensor is substantially different at the first and second times and if temperature sensed by the second temperature sensor is substantially different at the first and second times. The controller sends a full signal if temperature sensed by the first temperature sensor is substantially the same at the first and second times and if temperature sensed by the second temperature sensor is substantially the same at the first and second times.Type: GrantFiled: July 9, 2012Date of Patent: November 24, 2015Assignee: United Technologies CorporationInventors: Michael E. Mehrer, Richard Gunderson, Wagdy Wahba

Patent number: 8747456Abstract: A catheter assembly may include a main balloon arranged to reside within the main vessel, and a branch balloon configured to extend from the main vessel into the branch vessel. A stent may be situated around the main balloon and may include a branch aperture at a location between proximal and distal open ends of the stent. The branch balloon may extend from within the stent, through the branch aperture, and into the branch vessel. The branch balloon, when inflated, may extend into the branch vessel. The main balloon, when inflated, may also expand the stent within the main vessel. In some arrangements, the branch balloon, when inflated, can function as an anchor within the branch vessel that resists radial and axial movement of the stent relative to the branch vessel and main vessel during expansion of the stent by the main balloon.Type: GrantFiled: December 31, 2008Date of Patent: June 10, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Donald Baim, David L. Friesen, Richard Gunderson, Andrzej Malewicz, Michael Meyer, Daniel Quillin

Patent number: 7473271Abstract: A method and apparatus for reducing the longitudinal aspect of the catheter to stent force comprises at least one grip member for use with a stent delivery system. The grip engages a stent in the unexpanded state prior to delivery of the stent by retracting a stent retaining sheath. The grip comprises a body region having an outer diameter, a first end and a second end. The outer diameter of the first end is greater than the outer diameter of the second end. The grip is at least partially constructed from a polymeric material.Type: GrantFiled: April 11, 2003Date of Patent: January 6, 2009Assignee: Boston Scientific Scimed, Inc.Inventor: Richard Gunderson

Publication number: 20070282420Abstract: Medical device delivery systems, and related methods and components, are disclosed. In some embodiments, an implantable medical endoprosthesis delivery system includes a catheter, a sheath at least partially surrounding the catheter, and a tip coupled to a distal end portion of the catheter. The tip can cooperate with a distal end surface of the sheath to form a gap therebetween so that there is fluid communication between an interior region of the sheath and an exterior region of the sheath.Type: ApplicationFiled: August 14, 2007Publication date: December 6, 2007Inventor: Richard Gunderson
