Abstract
The radially expandable frame utilized during catheterization includes a guide wire, a radiopaque radially expandable frame with distal and proximal frame ends wherein the guide wire freely passes through the proximal frame end, an elongated actuation sleeve having a flexible distal end piece (coil strain relief) through which freely passes the guide wire, and a friction locking mechanism located at the proximal end of the system which is defined by the proximal ends of the actuation sleeve and guide wire. The expandable frame includes radiopaque frame struts and has a closed, radially compact form and an open, radially expanded form. The actuator flexible end piece is a coil which enables the system to flex in excess of 90 degrees. The actuator sleeve, at its proximal end, includes a friction locking mechanism having locking members with respective locking surfaces.
