Publication number: 20180085564Abstract: A drug-impregnated sleeve for encasing a medical implant is provided. In one embodiment, the sleeve may include a body made of a biologically-compatible material that defines an internal cavity configured to receive the medical implant. In one embodiment, the biologically-compatible material is bioresorbable. The body may include a plurality of apertures, such as perforations or holes, extending from the cavity through the body. The sleeve may further include a first end, a second end, and a drug impregnated into the resorbable sheet. In one possible embodiment, the first end of the sleeve may be open for receiving the medical implant therethrough and the second end may be closed. The implant may be encased in the sleeve and implanted into a patient from which the drug is dispensed in vivo over time to tissue surrounding the implantation site.

Patent number: 9925055Abstract: An expandable implant includes an implant body defining an internal void, the implant body including a plurality of interconnected linkages. A first plurality of the linkages has an expansion characteristic that is different from a second plurality of the linkages. An expandable bladder is sized to be disposed in the internal void. The bladder defines a bore configured to receive an expansion material, such that the expansion material applies an expansion force against the bladder, which thereby applies the expansion force against the implant body so as to cause the first linkage to expand greater than the second linkage. The expandable implant can be placed in a fracture location so as to restore height to a fractured target bone.Type: GrantFiled: May 25, 2016Date of Patent: March 27, 2018Assignee: DePuy Synthes Products, Inc.Inventors: Konrad Schaller, Beat Lechmann, Robert Frigg
