Abstract:
1. An apparatus for positioning a closure device within a passage, comprising: an elongate member comprising a proximal end, a distal end, and a lumen extending between the proximal and distal ends defining a longitudinal axis; a clip deliverable from the elongate member for sealing the passage; and a selectively expandable locator member extending through the lumen, the locator member comprising a distal portion extending distally beyond the distal end of the elongate member, the distal portion comprising an elongate deflectable element comprising a helically wound wire extending between a proximal end and a distal end, and having an intermediate portion therebetween, and a control element fixedly connected to the distal portion of the deflectable element and extending along an outer surface of at least one coil of the helical wound wire and passing through at least one coil of the helical wound wire in a pre-deployed configuration, the control element extending from the distal portion to the proximal end of the expandable locator member and being movable axially to buckle an intermediate portion of the deflectable element substantially transversely with respect to the longitudinal axis.
