Abstract
The construct described herein allows opposing tissues to form adhesions with either side of the construct, as part of the natural healing process. The construct however is multi-layered, wherein the space between the layers provides the protection from unwanted adhesions forming between and bonding separate tissues. In one embodiment, this space between layers of the construct may be developed spontaneously, that is the multiple layers are released by design after a finite time and the opposing tissues are free to move independent of each other, free of adhesions.
Claims27
A method for preventing the formation of adhesions following a surgical procedure comprising the step of placing a device between two tissues, said device comprising a plurality of layers, wherein said plurality of layers comprises at least an anterior layer and a posterior layer, said anterior and posterior layers each having an outer and inner surface, said outer surfaces serving to resist adhesion to tissue, said plurality of layers having at least one releasable attachment means arranged between said layers and attaching said layers together, wherein after implantation, said releasable attachment releases, whereupon said plurality of layers are completely releasably separate.
The method of claim 10 wherein said biologically active agent is released at a controlled rate.
