Abstract:
1. An apparatus for positioning a plug member within a passage through tissue communicating with a body lumen, comprising: an elongate member comprising a proximal end, a distal end, a lumen extending between the proximal and distal ends defining a longitudinal axis, and an outer surface; a threaded plug member coupled to the distal end of the elongate member, a periphery of a proximal-most end of the threaded plug member, at the coupling location of the threaded plug member and the elongate member, being disposed radially outwardly beyond the outer surface of the elongate member in both a pre-deployed configuration and a deployed configuration, the threaded plug member comprising a distal port therein in communication with the lumen and configured for sealing the passage; and a locator member extending from the threaded plug member, the locator member comprising an elongate deflectable element comprising a proximal end and a distal end, and a control element coupled to the distal end of the deflectable element, the control element being movable proximally for causing an intermediate portion of the deflectable element to transition from a first generally axial configuration to a second active configuration buckled substantially transversely with respect to the longitudinal axis.
