摘要:
Devices including, but not limited to, a self-expandable member having a proximal end portion and a main body portion. The self-expandable member is movable from a first delivery position to a second placement position, in the first delivery position the expandable member being in an unexpanded position and having a nominal first diameter and in the second position the expandable member being in a radially expanded position and having a second nominal diameter greater than the first nominal diameter for deployment within a vessel or duct of a patient. The expandable member includes a plurality of cell structures with the cell structures in the main body portion extending circumferentially around a longitudinal axis of the expandable member and the cell structures in the proximal end portion extending less than circumferentially around the longitudinal axis of the expandable member.
