The proximal frame member (120) is positionable adjacent an external surface of tissue and has first and second frame portions (123, 143) movable between a contracted condition and an expanded condition to expand an opening (122) defined therethrough. The membrane (180) defines a loop disposed about at least a portion of the proximal frame member (120) at a proximal end (182) thereof and is engaged to the distal frame member (160) at a distal end (182) thereof. The membrane (180) is transitionable between a crumpled condition and an extended condition upon transitioning of the proximal frame member (120) between the contracted condition and the expanded condition.1/11 L
