  • Patent number: 9368925
    Abstract: 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.

  • Patent number: 8929997
    Abstract: 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.

  • Patent number: 8414641
    Abstract: 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.

  • Patent number: 5611412
    Abstract: 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.

  • Patent number: 5490580
    Abstract: 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.
