Publication number: 20220117643Abstract: Implementations described herein include a hone cement mixing and delivery device including a cylindrical container defines a chamber and has an injection passage disposed at the distal end thereof. A plug can be removably disposable in the injection passage. The mixing screw is rotatably disposable in the chamber and has a screw thread extending along an outer surface of the mixing screw as well as a return passage extending through the mixing screw from the proximal end to the distal end thereof. In a mixing mode of the device, a mixing rod engages and rotates the mixing screw about the longitudinal axis of the cylindrical container causing material disposed in the chamber to be moved distally and return to the proximal end of the chamber through the return passage of the mixing screw. In an injection mode of the device, the plug can be removed from the injection passage and an injection rod occludes the return passage of the mixing screw.Type: ApplicationFiled: January 3, 2022Publication date: April 21, 2022Inventors: Sebastien Chaligne, Julie Mottet, Alexis Dupuy, Lenaic Giffard

Patent number: 11234749Abstract: In a bone cement mixing and delivery device, a plug can be removably disposable in an injection passage of a cylindrical container. A mixing screw can rotate in a chamber of the container and has a screw thread extending along an outer surface of the mixing screw as well as a return passage extending through the mixing screw from the proximal end to the distal end thereof. In a mixing mode of the device, a mixing rod engages and rotates the mixing screw about a longitudinal axis of the cylindrical container causing material disposed in the chamber to be moved distally and return to the proximal end of the chamber through the return passage of the mixing screw. In an injection mode of the device, the plug can be removed from the injection passage and an injection rod occludes the return passage of the mixing screw.Type: GrantFiled: November 21, 2017Date of Patent: February 1, 2022Assignee: Biomet SASInventors: Sebastien Chaligne, Julie Mottet, Alexis Dupuy, Lenaic Giffard

Patent number: 11229467Abstract: According to one example, a valve for an apparatus configured to mix bone cement is disclosed. The valve can include a base defining a first portion of a passage. The passage can be configured to allow a component of the bone cement through the valve. The valve can include a projection extending from the base to a base opposing end and forming a second portion of the passage that communicates with the first portion. The projection can have a frustoconically shaped surface that comprises one of an outer surface or an inner surface that forms a part of the second portion of the passage.Type: GrantFiled: April 4, 2019Date of Patent: January 25, 2022Assignee: Zimmer GmbHInventors: Alexis Dupuy, Sebastien Chaligne, Lenaic Giffard

Patent number: 10905485Abstract: An apparatus for mixing bone cement can comprise a receiving chamber, a mixing chamber, a cannula, a base, and a piston located within the mixing chamber. The receiving chamber defining a conduit. The mixing chamber in fluid communication with the receiving chamber. The mixing chamber configured to house a first component of the bone cement. The cannula located in the receiving chamber and in fluid communication with the conduit. The base including a bladder arranged to be punctured by the cannula, the bladder configured to house a second component of the bone cement. Upon puncturing of the bladder by the cannula the second component of the bone cement passes through the conduit and the cannula into the mixing chamber. The piston configured to seal the mixing chamber upon movement of the piston from a first position relative to the conduit to a second position relative to the conduit.Type: GrantFiled: July 26, 2017Date of Patent: February 2, 2021Assignee: Zimmer Biomet France SASInventors: Lenaic Giffard, Alexis Dupuy, Sebastien Chaligne, Julie Mottet

Patent number: 9889415Abstract: A device for storing and mixing bone cement components. The device includes a housing, a safety device, and a vacuum indicator. The housing defines a mixing chamber configured to store a first bone cement component therein. In a first safety position, the safety device prevents contact between the first bone cement component and a second bone cement component in the mixing chamber. In a second safety position, the safety device permits contact between the first and second bone cement components in the mixing chamber. The vacuum indicator restricts movement of the safety device from the first safety position to the second safety position when in a first vacuum indicator position. The vacuum indicator permits movement of the safety device from the first safety position to the second safety position when in a second vacuum indicator position.Type: GrantFiled: August 7, 2017Date of Patent: February 13, 2018Assignee: Biomet SASInventors: Lenaic Giffard, Cedric Cauquot, Alexis Dupuy
