The subject invention provides devices and methods for closing and sealing an opening in a conduit. The subject devices consist of an implantable flexible member adapted to conform to and seal with an inner surface of a conduit and further adapted to utilize the internal conduit pressure exerted thereon to form a substantially fluid-tight seal with the inner surface of the conduit whereby substances are prevented from leaking from the opening under normal physiological conditions. In the subject methods, a subject device is provided and positioned inside a conduit, operatively aligned over an opening to be sealed. The device is conformed to and sealed with an inner surface of the conduit and a substantially fluid-tight seal is formed between the device and the inner surface of the conduit utilizing the internal conduit pressure whereby substances within the conduit are prevented from leaking from the opening under normal physiological conditions.

What is claimed is: 1. A device for connecting first and second tissue structures comprising:first and second substantially parallel and elongate flexible segments each having proximal and distal ends, wherein the first and second segments each comprise a compliant material configured to be constricted for implantation within the first and second tissue structures, respectively, and wherein the material has a natural tendency to return to an unconstricted state such that, when implanted in the tissue structures, the material utilizes an internal fluid pressure within the respective tissue structure to conform to a shape of an inner surface of the tissue structure to provide a sealing contact with the inner surface; anda flow opening extending between the first and second segments at a point along the elongate length of the segments at least a distance from each of the proximal and distal ends to fluidically couple the first and second tissue structures.
