Publication number: 20160015411Abstract: Rotator cuff tears (complete and partial) are surgically repaired without needing more dermal access than percutaneous punctures. The surgeon is afforded a range of options for where to place a second tunnel in the bone, and selection by the surgeon of a desired bone bridge size is provided in advance of tunnel construction. Also, stitching in rotator cuff surgery can be accomplished without the need for suture anchors or added cost of secondary suture passers. Multiple stitch configurations including X-patterns are possible with combinations of preloaded loops and or sutures passed simultaneously through tissue and bone. Fixation is achieved without the use of suture anchors, buttons or other rigid implants.Type: ApplicationFiled: July 15, 2014Publication date: January 21, 2016Inventors: Douglas Keller, Ryan Vanleeuwen, Brian D.

Patent number: 8196237Abstract: A movable patient support includes a frame, a patient support surface supported at the frame, a base supporting the frame and having a plurality of bearing assemblies for moving the base along a floor surface. The support also includes a brake, a brake actuator for actuating the brake of at least one bearing assembly, and a brake bar coupled to the brake actuator. The brake bar is movable between a non-braking position and a braking position wherein the actuator causes the brake to move to its braking position. Further, the brake bar extends between the head end and the foot end of the frame and further has a portion extending outwardly from the brake actuator to at least close proximity to the bearing footprint defined by the bearing assemblies but within the frame footprint to thereby provide relatively easy access to the brake bar to an attendant standing adjacent one of the longitudinal sides of the frame.Type: GrantFiled: May 21, 2009Date of Patent: June 12, 2012Assignee: Stryker CorporationInventors: Cory Herbst, John Zerbel, Eugene L.
