Abstract
A surface is covered with microstructures that extend from the surface, and are made of a resilient material that allows the microstructures to bend or articulate. The microstructures are generally columnar and can have fingers on their distal or top end that is opposite the base from which the microstructures extend. In addition to the ordinary roughness presented by the microstructures, the articulation further discourages biofouling and bioadherence. The articulation of the microstructures can be oriented, and the orientations can be mixed or varied among the microstructures so that adjacent ones of the microstructures have different orientations of articulation.
Claims19
A wound dressing, comprising:
- a base having a major surface;
- and
- a plurality of articulating microstructures extending from and covering the major surface, wherein the articulating microstructures are generally columnar in shape, and provide a trough between microstructures.
A structure, comprising:
- a base;
- a plurality of columnar microstructures extending from the base, wherein the plurality of microstructures are made of a resilient material such that a distal end of each of the plurality of microstructures will articulate in response to a force being exerted on the microstructure;
- and
- each one of the plurality of microstructures has a plurality of fingers disposed in the distal end of the microstructure.
A wound dressing, comprising:
- a base having a surface, the base made of a resilient material;
- a plurality of microstructures that each extend from, and away from, the surface of the base, and wherein the plurality of microstructures are made of the same resilient material as the base and wherein each one of the microstructures are configured to articulate in response to cellular movement of tissue in contact with the microstructures in a wound during healing of the wound;
- wherein each one of the plurality of microstructures has a height of not more than 1000 micrometers, and wherein a spacing between adjacent ones of the plurality of microstructures is not more than 200 micrometers;
- wherein each one of the plurality of microstructures includes at least two fingers extending from a distal end of the microstructure;
- wherein each one of one of the plurality of microstructures has a non-regular cross section that defines an orientation of articulation of the microstructure;
- and
- wherein, among the plurality of microstructures there are at least two different orientations of articulations of different ones of the plurality of microstructures.
