    摘要： An actuator that includes an enclosure having a wall impermeable to a first solute and permeable to a solvent and containing, at least temporarily, a catalyst capable of promoting the transformation of at least one second solute into the first solute to vary the osmotic pressure in the enclosure; and a deformable chamber connected to the enclosure, the chamber being capable of increasing in volume under the action of the solvent moving from the enclosure into the chamber by osmosis or the enclosure being designed to be arranged in contact with the solvent, the chamber being capable of increasing in volume under the action of the solvent penetrating into the enclosure by osmosis.

    摘要： The present disclosure provides a biocompatible composite and method for its use in repairing tissue defects, including defects in cartilage. The biocompatible composite includes a fibrous polymeric component and a polymerizable agent, which is capable of forming the biocompatible composite in situ at the site of a tissue defect. In embodiments, the repair site at which the biocompatible composite is to be applied may be treated with a priming agent, permitting polymerization of the polymerizable agent to the tissue located at the repair site.
