Abstract:
1. An implantable device configured for placement at the opening of a physiological cavity and adjustable from a generally small diameter delivery condition to a deployed condition in which it assumes a larger diameter configuration, wherein the implantable device, in the deployed condition, comprises a substantially inverted U-shaped framework structure curving angularly away from a central longitudinal axis with at least two anchoring legs extending directly from the U-shaped framework structure, wherein the framework structure has at least one lateral area sized and configured to be positioned in proximity to the opening of the physiological cavity, wherein the at least two anchoring legs extend from the U-shaped framework structure generally opposite one another and along substantially parallel, opposed planes in the deployed arrangement, and further wherein the anchoring legs are sized and configured to contact tissue surface areas generally opposite one another on a neighboring lumen, and wherein the implantable device further comprises a membrane associated with at least a portion of the framework structure.
