Patent number: 11826061Abstract: An instrument for drilling a hole for a bone screw comprises a shaft having a primary drill fluted portion, a shank, and a middle portion there between. Part of an outer surface of the shaft's middle portion is non-curved. A sleeve surrounds the shaft. The sleeve has an inner surface that is complementary to the outer surface of the shaft's middle portion such that the sleeve slides with respect to the shaft. The sleeve's inner surface contacts the outer surface of the shaft's middle portion at the non-curved part such that the shaft can transmit torque to the sleeve. A countersink drill bit is provided at an end of the sleeve proximate the shaft's primary drill fluted portion. A locking mechanism selectively holds the sleeve in a fixed position with respect to the shaft, locating the countersink drill bit at a selected position with respect to the shaft's drilling end.Type: GrantFiled: May 19, 2021Date of Patent: November 28, 2023Assignee: Aristotech Industries GmbHInventors: Douglas Pacaccio, Jeremy Blair, Emmanuel Anapliotis

Publication number: 20130310835Abstract: Intramedullary medical devices (e.g., intramedullary nails) and methods for their use and manufacture are described herein. The intramedullary medical devices described herein may provide sustained compressive forces across a bone fusion site despite bone resorption processes. Through various embodiments, the intramedullary medical devices described herein may provide non-linear force curves relative to displacement. Intramedullary medical devices are described with multiple elements made of different materials. Examples of intramedullary medical devices are described with shape memory alloys.Type: ApplicationFiled: July 22, 2013Publication date: November 21, 2013Applicant: MedShape Inc.Inventors: Kenneth A. Gall, Kurt Jacobus, Heidi K. Waldman, Douglas Pacaccio, Mark Harrold

Patent number: 8118952Abstract: Bone fracture fixation devices, systems and methods of use and manufacture are provided. One such bone fixation device includes an elongate element having a responsive zone. The element is adapted to be coupled to the bone so that the responsive zone is positioned adjacent a fracture or fusion site in the bone. The responsive zone is adapted to apply a desired pressure to the bone when coupled thereto. In some embodiments, the responsive zone comprises a shape memory material, which may be nickel titanium or Nitinol, to apply compressive pressure across the fracture or fusion site for longer periods of time than standard bone screws.Type: GrantFiled: April 21, 2006Date of Patent: February 21, 2012Assignee: Medshape Solutions, Inc.Inventors: Kenneth A. Gall, Jeffrey A. Tyber, Douglas Pacaccio
