Abstract
A flat hernia implant with a flexible fabric formed from at least two textile fabric structures constructed substantially independently of one another and firmly interconnected over the entire surface area of the hernia implant so as to form a composite structure, is made available for use in surgery.
Claims30
Hernia implant for use in surgery comprising a flexible fabric formed from at least two substantially independently constructed textile fabric structures, which are firmly interconnected over the entire surface of the hernia implant to form a composite structure;
- wherein the composite components are formed from monofilaments having a thickness of about 10 to about 500 μm;
- said textile fabric structures are formed as net structures with at least two net structures having a substantially different structure from each other and at least one of said textile fabric structures having a pore;
- and said textile fabric structures are interconnected by knitting and are associated in a way that their structure pores are not aligned;
- wherein said hernia implant is made of at least one material which is at least partly absorbable in vivo and where, by way of in vivo degradation of said absorbable material, pore sizes in said hernia implant increase;
- and
- wherein said hernia implant has a bursting pressure of 100 to 300 kPa.
Method for the manufacture of a hernia implant by forming at least two independent textile fabric structures and joining said textile fabric structures over their surface area to form a composite structure in the form of a flexible fabric;
- wherein the composite components are formed from monofilaments having a thickness of about 10 to about 500 microns;
- said textile fabric structures are formed as net structures with at least two net structures having a substantially different structure from each other and at least one of said textile fabric structures having an opening;
- and said textile fabric structures are interconnected by knitting and are associated in a way that their structure pores are not aligned;
- wherein said hernia implant is made of at least one material which is at least partly absorbable in vivo and where, by way of in vivo degradation of said absorbable material, pore sizes of openings in said hernia implant increase;
- and
- wherein said hernia implant has a bursting pressure of 100 to 300 KPa.
