Abstract:
1. A catheter assembly for delivering an expandable prosthesis, the catheter having a proximal end and a distal end, the catheter comprising: a handle assembly on the proximal end of the catheter, the handle assembly including a rotatable distal control knob and a rotatable proximal control knob; a distal tip assembly including a first sleeve and a second sleeve; a first elongate member extending from the handle assembly, wherein the first elongate member has a proximal end and a distal end and the first sleeve is connected to the distal end of the first elongate member; and a safety button on the handle assembly; wherein the rotatable distal control knob is movably connected to the first elongate member, wherein the catheter is configured so that rotation of the rotatable distal control knob advances the first sleeve in a distal direction, wherein the safety button is configured to lock the rotatable distal control knob in place after the first sleeve has been advanced, wherein the safety button is configured to be radially moveable from a first position to a second position, and wherein the safety button is configured to prevent rotation of the distal control knob when the safety button is in the second position.
