Publication number: 20190388096Abstract: Apparatus and methods for occluding hollow body structures, such as blood vessels, and for attaching tissue layers together by providing implantable elements on opposite sides of the structure or tissue layers and drawing the implants together to occlude the body structure and/or bring the tissue layers together. The implants are deliverable in a low-profile configuration and self-expand to an enlarged configuration. The implantable elements are delivered by transfixing the body structure, then releasing the implants on opposite sides of the anatomical structure to urge the layers together to effect an occlusion or attachment. The implants are configured to apply oppositely directed forces to opposite surfaces of the tissue layers at alternate, circumferentially spaced locations and may constrain the tissue in a serpentine pattern or in a direct clamping pattern. The implants grip the tissue in a manner that defines a pressure zone about the transfixion aperture that prevents leakage from the aperture.Type: ApplicationFiled: June 24, 2019Publication date: December 26, 2019Applicant: Amsel Medical CorporationInventors: Arnold Miller, Raanan Miller, Nir Lilach, William E.

Publication number: 20190388099Abstract: A method and system to align a pin or drill a tunnel along a single line in space with a two degree of freedom (2-DOF) surgical device in a patient is provided. A plane is defined relative to a desired location for an implant or tunnel on a bone, where the implant or tunnel has an axis. An end-effector of the 2-DOF surgical device is aligned coincident with the plane, and the 2-DOF surgical device is moved side-to until a first indicator signals when the end-effector aligns with an entry point for the desired location for the implant or tunnel on the bone. A tip of the end-effector is anchored into the bone at the entry point; and the 2-DOF surgical device is rotated about the anchored tip until a second indicator signals when the end-effector aligns with the axis of the implant or tunnel at the desired location.Type: ApplicationFiled: September 6, 2019Publication date: December 26, 2019Inventors: Joel Zuhars, Stan G.

Publication number: 20190388100Abstract: An apparatus and methods are provided for a trephine bone graft harvester for extracting morselized bone from patients. The trephine bone graft harvester includes a bone cutter affixed to an outer hub. The bone cutter comprises a hollow tube having cylindrical wall and a distal cutting edge. A bone graft collector is sheathed within the bone cutter. The bone graft collector includes a distal scoop adjacent to the distal cutting edge of the bone cutter. The distal scoop is configured to move morselized bone away from the distal cutting edge. An inner hub is affixed to the bone graft collector and coupled with the outer hub. The inner hub includes a proximal shank configured to be engaged with a rotary tool suitable for applying torque to the inner hub.Type: ApplicationFiled: February 26, 2019Publication date: December 26, 2019Applicant: ln2Bones USA, LLCInventors: Arley Perez, Rebecca Hawkins Wahl

Publication number: 20190388101Abstract: Medical devices for filing bones are described. A bone file has a kidney-shaped main body and a handle. The kidney-shaped main body has a leading recess that extends between first and second arm portions and a first surface that defines a kidney-shaped filing surface. A handle is continuous with the main body and extends away from the leading recess. The handle has a handle end portion opposite the leading recess that defines an aperture.Type: ApplicationFiled: April 9, 2019Publication date: December 26, 2019Inventor: Richard E. Grant

Publication number: 20190388104Abstract: A surface digitizing tool has a film of micro-sensor elements, with each micro-sensor element related in a network affected by a shape of the film. The film is flexible to conform to a shape of a selected surface of an object. A processing unit receives signals from the micro-sensor elements of the network. The processing unit has a model generator producing a model of the selected surface of the object from the signals of the network of resistive elements. A positioning frame aligns a position and orientation of a drilling tool with respect to a bone element.Type: ApplicationFiled: September 9, 2019Publication date: December 26, 2019Inventors: Louis-Philippe AMIOT, Eric SZMUTNY, Louis MALETTE
