Japanese Patent JPH10500584
Kind Code:

Abstract:
A catheter system includes a catheter sheath and a flexible working shaft within a working lumen of the sheath. The sheath includes a monorail-type guidewire lumen at its distal end, and a stiffening member is provided adjacent a side port of the monorail guidewire lumen to inhibit prolapse of the catheter as it is introduced past a bend or curve over a guidewire. In a first embodiment, the stiffening member may be secured directly within a working lumen of the catheter body. In a second embodiment, the stiffening member may be attached to a distal end of the working shaft, typically an imaging core.
