Abstract
A process for the manufacture of a prosthetic sheet with improved tissue healing characteristics useful in reinforcing tissue defects is disclosed. Generally the prosthetic may be comprised of any material that does not promote fibrosis and inflammation. In particular, the prosthetic may be comprised of non-absorbable hydrogel reinforced with fiber, so that the fiber reinforcement is encapsulated and shielded from interaction with tissue. The prosthetic may contain pores that pass through it to encourage tissue through-growth. These pores may be made by removing material from a sheet of reinforced hydrogel or the reinforcement means may contain a porosity around which the hydrogel is formed and the porosity is maintained.
Claims20
An improved implantable prosthetic reinforcement device for tissue, the device comprising:
- a structural component providing reinforcement;
- a hydrophilic surface component providing tissue compatibility;
- and
- through-holes passing through the device and being of sufficient size to allow through-growth of the tissue that is being reinforced;
- wherein the spacing of the through-holes is selected to minimize fibrotic stimulation.
A method for the minimization of fibrosis-induced contracture in a reinforcing prosthetic, the method comprising:
- providing, as the outermost layer of said reinforcing prosthetic, a hydrophilic material, consisting essentially of a poloxamer-based polyurethane, wherein said hydrophilic material hydrates to a water content of at least about 4% upon contact with aqueous solutions or fluids.
