Abstract: Novel scaffolds for tissue engineering muscle are provided that include copolymers of a polyalkylene glycol and an aromatic polyester in the form of a matrix. The scaffold can include autologous muscle cells and/or stem cells.

Abstract: A prosthetic repair fabric and method for repairing an inguinal hernia in the inguinal canal. The prosthesis including a layer of mesh fabric that is susceptible to the formations of adhesions with sensitive tissue and organs, and a barrier layer that inhibits the formation of adhesions with sensitive tissue and organs. The mesh fabric including a medial section and a lateral section that are configured to be positioned adjacent the medial corner and the lateral end of the inguinal canal, respectively, when the prosthesis is placed in the inguinal canal to repair the defect. The barrier layer is positioned on the mesh fabric to inhibit the formation of adhesions between the spermatic cord and the mesh fabric. At least a portion of the lateral section of the mesh fabric is free of the barrier layer on both of its sides to promote enhanced tissue ingrowth therein.

Abstract: New artificial muscles and actuators, that are operated by hydrogen gas as working fluid stored interstitially in metal hydrides as a hydrogen sponge. These artificial muscles and actuators are operated both electrically and thermally. The artificial muscles and actuators have fast response, are compact/light-weight, are noiseless, and produce high-power density. They can be used for biomedical, space, defense, micro-machines, and industrial applications.
