ABSTRACT:
The methods and apparatus of the present invention permit a stable body pocket to be formed utilizing multiple biocompatible sheets or using only a single biocompatible sheet positioned to create either a potential space or actual space stable body pocket. The sheets have one surface which permits tissue ingrowth and thereby stably secures the sheet in the desired position. The other sheet surface is non-adhering such that adherence to a facing surface does not occur thereby creating a stable body pocket. In addition, a stable body pocket can be formed by using a biocompatible sheet or sheets having a surface that is selectively capable of permitting tissue ingrowth such that some portions of the surface grows into the surrounding tissue and other portions of the surface do not adhere to the surrounding tissue. In this manner, the stable body pocket apparatus has flexible surface portions. Stable body pocket access channels can also be formed according to the methods and apparatus of the present invention. Such access channels can provide stable means for communicating between the exterior of the body and a natural or created internal body pocket. A method for forming a stable body pocket utilizing fluid pressure introduced into the space where a body pocket is desired is also in accord with the present invention.
