Abstract
A device positionable in an opening in a flexible membrane or in the lumen of a vessel having a flexible sidewall. The device distends or biases opposite portions defining the opening or forming the vessel sidewall outwardly in the plane of the device. The outward biasing draws opposing portions of the opening or sidewall inwardly in a direction perpendicular to the plane of the device and into apposition or contact.
