Patent number: 12232963Abstract: A bioactive filamentary structure includes a sheath coated with a mixture of synthetic bone graft particles and a polymer solution forming a scaffold structure. In forming such a structure, synthetic bone graft particles and a polymer solution are applied around a filamentary structure. A polymer is precipitated from the polymer solution such that the synthetic bone graft particles and the polymer coat the filamentary structure and the polymer is adhered to the synthetic bone graft particles to retain the graft particles.Type: GrantFiled: February 8, 2024Date of Patent: February 25, 2025Assignee: Howmedica Osteonics Corp.Inventors: Sonny Sheth, David Arazawa, J. Brook Burley, Sarah Elizabeth Smith, Matthew B. Havener, James San Antonio, Marc Gilles Long

Patent number: 11471302Abstract: A device for loading bone graft material into a delivery tube is provided herein. The device includes a housing defining a reservoir for receiving bone graft, a magazine at least partially disposed within the housing, and an actuation member coupled to the housing for discharging the bone graft material into the delivery tube. The magazine defines a first chamber and a second chamber and is moveable between a first position in which the first chamber is in communication with the reservoir and a second position in which the second chamber is in communication with the reservoir. The actuation member includes a plunger configured to slide into the first chamber and the second chamber to discharge bone graft material, when bone graft material is contained therein, into the delivery tube. Methods of loading bone graft material are also provided.Type: GrantFiled: November 20, 2020Date of Patent: October 18, 2022Assignee: Stryker European Operations Holdings LLCInventors: David Arazawa, Brian Sechrist, Oliver Buchert, Amir Ali Sharifi-Mehr
