Patent number: 9368925Abstract: An IS-4 terminal connector assembly includes three terminal electrodes positioned over an inner tubular member such that they are radially offset from one another. Each of the terminal ring electrodes are configured such that they can withstand both tensile and cyclical bending loads with minimal compromise in their outer geometry. Additionally, each of the terminal electrodes is configured such that they have both an inner and outer geometry that facilitates adequate insulation between a select terminal electrode and an adjacent conductor. Additionally, each of the terminal ring electrodes is configured such that they facilitate an external approach to staking a cable conductor.Type: GrantFiled: November 18, 2013Date of Patent: June 14, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: Lily Lim, Ronald W. Kunkel, Joseph C. Walker, Peter C. Hall, Steven E. Schultz, Devon N. Arnholt, Angelo Fruci

Patent number: 8929997Abstract: An active fixation lead may have a lead body formed at least in part from an inner member and an outer sheath. The inner member may include a pace/sense lumen and one or more cable lumens. The inner member may include one or more longitudinally extending crumple zones that are configured to reduce stress within the pace/sense lumen that could otherwise be caused by compressive forces applied to the lead.Type: GrantFiled: December 16, 2013Date of Patent: January 6, 2015Assignee: Cardiac Pacemakers Inc.Inventors: David R. Wulfman, Douglas D. Pagoria, Joseph C. Walker

Patent number: 8414641Abstract: A valve for use in a body lumen, where the valve includes a valve leaflet with delayed leaflet deployment relative an in vivo implant time. The valve includes a valve frame, a valve leaflet coupled to the valve frame. The valve leaflet includes a commissure that can reversibly seal for unidirectional flow of a liquid through the valve, and a biodegradable adhesive between the valve leaflet and the valve frame to hold at least the commissure of the valve leaflet in a static relationship relative the valve frame for a predetermined time once implanted in vivo.Type: GrantFiled: March 2, 2012Date of Patent: April 9, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Patrick J. Stocker, Joseph C. Walker

Patent number: 5611412Abstract: A hitch assembly is disclosed for an elevator car suspended by hoist ropes and driven by a drive sheave. The hitch assembly having a hitch plate with openings for thimble rods, wherein geometrical planes bisecting the openings for the thimble rods are substantially coplanar with geometrical planes bisecting hoist rope grooved recesses in the drive sheave. Another feature of the present invention is a vibration isolation assembly for fastening the hitch plate to a mounting plate fixed to the elevator car, wherein the vibration isolation assembly isolates vibrations transmitted to the elevator car from the hoist ropes. Still another feature of the hitch assembly is a rope tension equalization assembly for fastening the hoist ropes to the hitch plate, wherein the rope tension equalization assembly equalizes tensions among the hoist ropes.Type: GrantFiled: July 7, 1995Date of Patent: March 18, 1997Assignee: Otis Elevator CompanyInventors: Young S. Yoo, Joseph C. Walker

Patent number: 5490580Abstract: An automated arrangement selects one of a plurality of load weight bypass thresholds for an elevator car. The selection depends, for example, upon the car direction and the time of day. Alternative embodiments of the arrangement utilize in the selection either actual or estimated elevator car floor space. Fuzzy logic is used to estimate available floor space.Type: GrantFiled: April 17, 1995Date of Patent: February 13, 1996Assignee: Otis Elevator CompanyInventors: Bruce A. Powell, Joseph C. Walker
