Abstract
An areal implant, in particular for abdominal wall closure, has a flexible basic structure made from a knitted fabric comprising non-resorbable or slowly resorbable material or a combination of such materials. The knitted fabric of the basic structure is designed to stretch more than the tissue region destined to receive the implant below a critical force and stretch less than this tissue region above the critical force. The critical force lies below the highest load which is allowable for this tissue region. The basic structure is provided with a stiffening, synthetic resorbable material whose resorption time is less than that of the basic structure.
Claims16
An areal implant comprising:
- a flexible knitted fabric having an initial tearing strength which optionally has a resorption time of at least 60 days,
- wherein the flexible knitted fabric is designed to stretch more than a tissue region destined to receive the implant below a critical force and stretch less than the tissue region above the critical force, the critical force being below a highest load allowable for this tissue region, and
- a synthetic resorbable material, which stiffens the flexible knitted fabric, whose resorption time is less than that of the flexible knitted fabric, wherein the synthetic resorable material is selected from the group consisting of yarns, monoflaments, and combinations thereof.
