Abstract:
A controllable deployment system for a radially expandable frame utilized during catheterization comprising:a guide wire having a proximal end, a distal end and a stop near said distal end: a radially expandable frame having a closed, radially compact, elongated form and an open, radially expanded, longitudinally foreshortened form, said frame having distal and proximal frame ends; said guide wire extending through said expandable frame and said guide wire being freely movable, both rotatably and longitudinally, with respect to said expandable frame except distally beyond said stop; a releasable latch formed by said stop and a complementary latch lock, said complementary latch lock formed on the distal frame end, said releasable latch permitting radial deployment and radial closure of said frame based upon movement of said guide wire relative to said frame.
