Abstract
A catheter including fluoroscopic marker components disposed in the catheter distal end portion to provide enhanced fluoroscopic visibility of the catheter end portion. Various embodiments of the marker include a cylindrical plug disposed within the catheter tip, a half section catheter tip, a longitudinal stripe along a sidewall of the catheter end portion, and multiple combinations of marker plugs and marker stripes to provide enhanced in vivo fluoroscopically visible catheter disposition information to the physician. An enhanced embodiment of the present invention includes an orientation marker that is disposed on the steering handle, particularly on the control knob, to provide visual and tactile information to the catheter user regarding the direction to manipulate the control knob in order to maneuver the catheter distal end portion.
