Patent ID: 8603136

Claim:
An apparatus for sealing a passage through tissue communicating with a body lumen, comprising: an elongate member having a proximal end, a distal end, and a lumen extending between the proximal and distal ends defining a longitudinal axis; a plug member disposed on the distal end of the elongate member, the plug member comprising a thread pattern on its outer surface, the plug member comprising a distal port therein in communication with the lumen; and a locator member extending distally from the distal port, the locator member comprising an elongate deflectable element comprising a proximal end and a distal end, and a control element fixedly connected to the distal end of the deflectable element, the deflectable element including a helically wound member having a proximal end spaced apart from a distal end in the longitudinal axis, the distal end of the helically wound member being the distal end of the elongate deflectable element, the control element being movable proximally and axially to buckle an intermediate portion of the deflectable element from an elongated delivery configuration to a buckled transverse configuration with respect to the longitudinal axis.
