Abstract
A non-over-the-wire catheter for use in angioplasty including a core wire which extends distally beyond a distal end of a tubular member. The tubular member defines an interior passage which is in fluid communication with a distal interior passage of a waist tube that extends about the core wire. An inflatable balloon member extends about the core wire and is in fluid communication with the distal interior passage of the waist tube. A torsionally soft component is coupled between the balloon member and the core wire. The torsionally soft component absorbs torque applied to the tubular member and conveyed along the core wire such that the torque is not readily transmitted to the balloon member from the core wire.
