Patent number: 11197663Abstract: Apparatus for securing an object to bone, the apparatus comprising an anchor comprising a body comprising a passageway; and a movable element comprising a deformable portion; wherein the deformable portion is configured so that, (i) at a first level of force, the deformable portion restricts proximal movement of the movable element, and (ii) at a second, greater level of force, the deformable portion deforms and permits proximal movement of the movable element.Type: GrantFiled: October 9, 2018Date of Patent: December 14, 2021Assignee: Stryker Puerto Rico LimitedInventors: Jeremy Graul, J. Brook Burley

Publication number: 20090299219Abstract: An apparatus for removing tissue and/or other material from a patient, particularly a breast of a patient, is provided. The apparatus generally includes a handpiece and a tissue removal mechanism connected thereto. The tissue removal mechanism includes a cannula having an open distal tip and an outer diameter of less than about 5 mm, or less than about 2 mm. The mechanism further includes a rotatable element having a distal portion with helical threading. The distal portion of the rotatable element extends beyond the open distal tip of the cannula in order to allow tissue to prolapse between turns of the helical threading. The apparatus is designed to draw soft tissue into the cannula upon rotation of the rotatable element and without the need for supplemental sources of aspiration.Type: ApplicationFiled: July 31, 2009Publication date: December 3, 2009Applicant: Stryker Puerto Rico LimitedInventor: D. Russell Pflueger
