Patent ID: 8518106

Claim:
A catheter for delivering an expandable prosthesis, the catheter comprising: a handle assembly including: a rotatable distal control knob; a rotatable proximal control knob; a distal guide wire shaft boss engaged with the distal control knob; a connecting bar attached to the distal guide wire shaft boss; and a proximal guide wire shaft boss operatively coupled to the first elongate member and the connecting bar; 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 second elongate member extending from the handle assembly, wherein the second elongate member has a proximal end and a distal end and the second sleeve is connected to the distal end of the second elongate member, wherein the rotatable distal control knob is connected to the first elongate member, and wherein the catheter is configured so that rotation of the rotatable distal control knob moves the first sleeve in an axial direction, and wherein the rotatable proximal control knob is connected to the second elongate member, and wherein the catheter is configured so that rotation of the rotatable proximal control knob moves the second sleeve in an axial direction.
