Abstract
The present invention discloses a mesh like fabric for implantation beneath or within the dermis to control formation of scar tissue; the fabric being aligned such that its axis having the greatest resistance to distension is aligned parallel to the predominant stresses to which a wound is thought to be subject these being principally parallel to the wound line; axes of the fabric having lesser resistances to distension serving to control other stresses within the dermis transverse to the predominant longitudinal stresses; the fabric being provided with a binder in order to maintain the mesh structure in a known pre-stressed orientation.
Claims16
A soft, fine, bio-compatible, long term bio-degradable mesh-like fabric fixed by a bio-compatible binder in a pre-stressed state such that the fabric is relatively resistant to distension along one axis of its surface as compared to at least one other such non parallel axis;
- wherein the binder is adapted to lose its rigidity soon after, but not immediately upon, contact with body fluids.
A method for sub-dermally or intradermally implanting a fabric to control formation of scar tissue which comprises implanting a bio-compatible, long-term bio-degradable mesh-like fabric which is fixed by a temporary bio-compatible binder in a pre-stressed state, said fabric being non-distensible along one axis as compared with its distensibility along at least one other non-parallel axis, into or just under the dermis proximate the wound in such a manner that the relatively non-distensible axis of the fabric is parallel to the suspected primary stress carrying axis within the dermis.
