Patent number: 11039916Abstract: A radially expandable sheath is provided having a substantially closed distal end with at least two sidewalls extending proximally therefrom and defining a central lumen. Each sidewall can have a substantially concave outer surface adapted to seat a graft member, and each side wall is at least partially separated by a longitudinally oriented slot that extends from a proximal end along a substantial length of each sidewall. The slot preferably terminates at a position just proximal to the distal end. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel.Type: GrantFiled: March 27, 2019Date of Patent: June 22, 2021Assignee: DePuy Synthes Products, Inc.Inventors: Lisa M.

Patent number: 10085737Abstract: A suture anchor is provided including an elongate shank defining a longitudinal axis and having at least one bone-engaging thread formed thereon, and a drive head having a proximal end and a distal end mated to the elongate shank. The drive head has a substantially oval shape and includes at least one suture attachment member formed in a portion of the drive head. The configuration of the drive head is particularly advantages in that it provides a suture anchor having improved physical properties, including a high failure torque and a high stripping strength.Type: GrantFiled: October 29, 2015Date of Patent: October 2, 2018Assignee: DEPUY MITEK, LLCInventors: Robert Boock, Nathan S.

Patent number: 8585610Abstract: Devices and methods are provided for extracting and macerating tissue, and optionally for depositing the tissue onto a tissue scaffold. The device generally includes an outer tube having a substantially open distal end that is adapted to be placed on and preferably to form a seal with a tissue surface, and a shaft rotatably disposed within the outer tube and movable between a first, proximal position in which the shaft is fully disposed within the outer tube, and a second, distal position in which a portion of a distal end of the shaft extends through the opening in the distal end of the outer tube. The device also includes a tissue harvesting tip formed on the distal end of the shaft that is effective to excise a tissue sample when the shaft is moved to the distal position, and a cutting member that is coupled to the shaft at a position proximal to the tissue harvesting tip. The cutting member is effective to macerate a tissue sample excised by the tissue harvesting tip.Type: GrantFiled: June 28, 2011Date of Patent: November 19, 2013Assignee: DePuy Mitek, LLCInventors: Robert J.
