Publication number: 20230144510Abstract: Disclosed is a joining element (10), especially a suture material for surgical use. The joining element (10) is composed of a first material (12) that is essentially rigid during impingement by a relatively short-lasting tensile load on opposite sides as well as a second material (11) which is connected to the first material. The second material is substantially rigid during impingement by said tensile load on opposite sides while contracting slowly during a second period of time that is longer than the first period of time.Type: ApplicationFiled: September 14, 2022Publication date: May 11, 2023Inventors: Joerg Mayer, Jochen Ganz, Beat Keller, Ralph Hertel

Patent number: 11471154Abstract: Disclosed is a joining element, especially a suture material for surgical use. The joining element is composed of a core having a length that extends along a longitudinal direction, the core including a polymer material and an osmotically active substance distributed within the polymer material, wherein the core has a volume capable of swelling along a transverse direction that is perpendicular to the longitudinal direction upon exposure to a fluid; and, a diffusion-controlling extendable membrane that surrounds at least a portion of the length of the core, wherein the membrane is configured to regulate hydration of the core by the fluid, and is further configured to expand along the transverse direction in response to swelling of the core.Type: GrantFiled: December 23, 2019Date of Patent: October 18, 2022Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Joerg Mayer, Jochen Ganz, Beat Keller, Ralph Hertel

Patent number: 9757120Abstract: The present disclosure is directed to a joining element elongate in a longitudinal direction including an inner core extending substantially in the longitudinal direction and an outer sleeve surrounding at least a portion of the inner core. The sleeve includes a lattice that defines at least one angle with respect to the longitudinal direction and the core is swellable against the sleeve along a direction perpendicular to the longitudinal direction to thereby increase the angle with respect to the longitudinal direction. The disclosure is further directed to a method of joining a first a second material including the joining element of the present disclosure.Type: GrantFiled: March 13, 2013Date of Patent: September 12, 2017Assignee: DePuy Synthes Products, Inc.Inventors: Joerg Mayer, Jochen Ganz, Beat Keller, Ralph Hertel
