Structure having fibres which are adhesively bonded to one another in locations
The invention relates to a structure having fibers which are adhesively bonded to one another in locations and have a permeability for air of between 0.5 ml/min*cm 2 and 1.5 ml/min*cm 2 , wherein said structure has an at least one-sided coating which reduces the permeability of the structure to below 0.2 ml/min*cm 2 .
1. An implant structure with fibers which are adhesively bonded to one another in locations, which have a permeability for air of between 0.5 ml/min*cm 2 and 1.5 ml/min*cm 2, wherein said structure with fibers has at least a one-sided coating, which reduces the permeability of the structure to less than 0.2 ml/min*cm 2.
2. The implant structure according to claim 1 , wherein the fibers are made of polyurethane.
3. The implant structure according to claim 1 , wherein the structure is a fleece material.
4. The implant structure according to claim 1 , wherein the fibers are adhesively bonded to form a cylinder and the coating is disposed on the inside surface of the cylinder.
5. The implant structure according to claim 1 , wherein the coating comprises gelatine.
6. The implant structure according to claim 1 , wherein the coating comprises collagen.
7. The implant structure according to claim 1 , wherein the coating comprises fibrin.
8. The implant structure according to claim 1 , wherein the coating comprises a medical drug.
9. The implant structure according to claim 1 , wherein the coating is reabsorbed after one to 30 days to no more than 10% of the original amount.
10. The implant structure according to claim 9 , wherein the coating is reabsorbed after 2 to 14 days to no more than 10% of the original amount.
