Patent number: 5643251Abstract: A guide wire for a catheter has a tubular portion with a flexible body fixed to its distal end. The distal end of the body may be composed of a radiopaque material. Optical fibers are disposed within the assembly and terminate in a radiopaque tip at the distal end of the body. The guide wire may have a longitudinal marker wire or mandrel for providing stiffness and radioscopic tracking characteristics, as well as providing torsional control and tip shaping capabilities. The guide wire has a proximal end attached to the tube and a distal end that also terminates in the tip. The wire may be maneuvered in a vascular area like a conventional guide wire and may be used in conjunction with a support catheter to increase its maneuverability. Then, laser energy is conveyed to the vascular area by the optical fibers to ablate an obstruction. The proximal end of the guide wire is then removed and a larger catheter may then be slid over the guide wire to continue the ablation operation.Type: GrantFiled: October 4, 1995Date of Patent: July 1, 1997Assignee: Spectranetics CorporationInventors: Cecily M.

Patent number: 5352197Abstract: The present invention is a turn limiter for a catheter with a twistable tip. The catheter having a flexible wall for use in complex twisting anatomy contains a torque wire or a torquable guide wire lumen. The torque wire or torquable guide wire lumen extends through the length of the catheter and is attached to the catheter at or near the distal end thereof. The proximal end of the torque wire protrudes from the proximal end of the catheter and is attached to a turn limiter. Rotation of the turn limiter imparts a torque to the torque wire or torquable guide wire lumen. The turn limiter allows limited rotation of the proximal end of the torque wire or torquable guide wire lumen without axial dislocation. The turn limiter may have a feature for indicating the amount of torque applied to the torque element.Type: GrantFiled: March 12, 1993Date of Patent: October 4, 1994Assignee: The Spectranetics CorporationInventors: Dan J.
