Abstract
Described is a haemostatic device comprising a substrate and a surface formed on the substrate. The surface comprises at least one of micro- and nano-sized materials, the materials being partially embedded in a base, the surface substantially preventing wetting of the substrate. An embodiment of the device is carbon nano fibres embedded partially in a PDMS or PTFE base, on a substrate.
Claims18
A haemostatic device comprising:
- a substrate;
- and
- a surface formed on the substrate, the surface comprising at least one of micro- and nano-sized materials, the materials being partially embedded in a base, the surface substantially preventing wetting of the substrate, wherein the materials comprise hydrophobic nanofibers immobilized in the base, wherein the surface has a surface morphology that entrains air pockets between the surface and a liquid coming into contact with the surface.
A haemostatic coating dispersion comprising at least one of micro- and nano-sized materials, and a base in a dispersion, for depositing on a substrate to form a hydrophobic surface comprising the materials partially embedded in the base, the surface substantially preventing wetting of the substrate, wherein the materials, when at least partially embedded, are hydrophobic, and the materials comprise nanofibers immobilized in the base on formation of the hydrophobic surface, wherein the surface has a surface morphology that entrains air pockets between the surface and a liquid coming into contact with the surface.
