Publication number: 20250241758Abstract: Methods for making surgical implants (or grafts) comprising tissue-derived pieces derived from cartilage, dermis, placenta, and combinations thereof, and which are shaped using a container or mold, or by compressing the tissue-derived pieces, into a first shape, including but not limited to a cylinder, a plug, or a sheet, and possibly also a secondary shape such as when the first shape is a sheet. Prior to shaping the tissue-derived pieces have one or more physical forms selected from fibers, flakes, particles, and powder. The implants are at least partially crosslinked by exposure to UV radiation, whereby the implants retain the first shape, as well as the secondary shape when present, when rehydrated, when compressed or subjected to cyclical loading. The implants stay in one piece and do not disperse when subjected to a load, during and after rehydration, during irrigation, or when placed in an aqueous environment.Type: ApplicationFiled: April 17, 2025Publication date: July 31, 2025Inventors: Michele Christine McAllister, David Wang, Michelle Bubear, Joed Canales, Amy Chang, Roman Shikhanovich, Mark Spilker, Eric Semler

Patent number: 12295848Abstract: Methods for making surgical implants (or grafts) for the repair of bone defects, and more particularly, surgical implants that include demineralized bone fibers, are disclosed. Also disclosed are methods for increasing the wettability and ensuring uniform density of such implants. The surgical implants have a wettability time of less than 5 minutes and a residual moisture content of less than 6% by weight, and they remain cohesive and retain their shape upon complete rehydration.Type: GrantFiled: October 14, 2022Date of Patent: May 13, 2025Inventors: Michele Christine McAllister, David Wang, Michelle Bubear, Joed Canales, Amy Chang, Roman Shikhanovich, Mark Spilker, Eric Semler

Publication number: 20230389911Abstract: The invention provides an applicator of a spongeous collagen membrane and a kit comprising such applicator and such membrane. The applicator comprises an applicator body having a guide extending in a direction from the proximal end to the distal end of the applicator body and a sliding element slidably comprising a shaft portion movable along the guide. The sliding element is provided at its distal end with a contact portion for contacting the spongeous collagen membrane, and the contact portion of the sliding element comprises mechanical fixation means configured to releasably hold the spongeous collagen membrane without substantially generating forces acting in the distal direction on the spongeous collagen membrane over its area extension. The distal end of the applicator body comprises a release surface configured to apply a release force to the spongeous collagen membrane releasing it from the mechanical fixation means for application to the wound site.Type: ApplicationFiled: October 14, 2021Publication date: December 7, 2023Applicant: GEISTLICH PHARMA AGInventors: Michael TRITTO, Niklaus STIEFEL, Raphael KAUFMANN, Mark SPILKER

Patent number: 11786637Abstract: Methods and compositions for preparing and priming a tissue graft for an accelerated therapeutic effect are provided herein. In one embodiment, the method includes obtaining a tissue containing viable cells from a donor, wherein the viable cells are endogenous to the tissue and remain resident in the tissue; and priming the viable cells with one or more stimuli comprising simulated hypoxia to produce a primed tissue, wherein when grafted to a recipient the primed tissue provides a benefit compared to non-primed tissue.Type: GrantFiled: March 1, 2021Date of Patent: October 17, 2023Assignee: Musculoskeletal Transplant FoundationInventors: Eric Semler, Mark Spilker, Kevin Wu, Yen-Chen Huang, Evangelia Chnari, Jeffrey Cartmell, Morris Jacobs, Alison Ling, Moon Hae Sunwoo
