Abstract:
1. An apparatus for promoting tissue growth comprising: a biocompatible matrix having a plurality of microstructures, each microstructure being constructed and arranged to apply a mechanical stimulus to a tissue surface, wherein the apparatus is configured such that an application of a first mechanical stimulus by a first microstructure of the plurality of microstructures is separately controllable from an application of a second mechanical stimulus by a second microstructure of the plurality of microstructures; and a chamber which is controllable via pneumatic actuation to effect macroscopic contraction of a tissue wound; wherein the chamber is compressible via pneumatic actuation such that when the biocompatible matrix is applied to the tissue wound and the chamber is compressed, at least two spatially separated regions of wound tissue are brought closer to each other.
