CATHETER STRUCTURES FOR REDUCING FLUOROSCOPY USAGE DURING ENDOVASCULAR PROCEDURES

摘要

A catheter structure, such as a balloon catheter (30), guidewire, or the like, with markings (32) perceptible outside of the vasculature is for use in determining at a location external to the body the position of the catheter structure relative to a treatment area. Related kits are also disclosed.

主权项

1. A kit for treating a treatment area in a vasculature of a patient, comprising:
a guidewire having a first distal portion adapted for positioning at or near the treatment area and a first proximal portion including a plurality of first markings perceptible by the clinician external to the vasculature without the use of fluoroscopy, each of the plurality of first markings being representative of a length from a first predetermined starting point on the guidewire; and a catheter having a shaft including second distal portion adapted for positioning at the treatment area and a second proximal portion including a plurality of second markings perceptible by the clinician external to the vasculature without the use of fluoroscopy, each of the plurality of second markings being representative of a length from a second predetermined starting point of the catheter; wherein a distance between the first predetermined starting point and each of the first markings corresponds to a distance between the second predetermined starting point and each of the second markings.
