ABSTRACT:
A catheter has a handle and a guide tube enclosing an interior bore. The guide tube has a proximal end and a distal end. A friction sleeve joins the proximal end of the guide tube to the handle. The friction sleeve extends from the handle and grips a portion of the guide tube beyond the handle. The friction sleeve forms a hand grip for the user beyond the confines of the handle. It also serves to effectively transmit torque applied at the handle to the distal end of the guide tube.
