Catheter with multiple visual elements
First Claim
Patent Images
1. A catheter assembly, comprising:
- a catheter handle coupled to an insertion tube, the insertion tube including at least one lumen extending at least partially through the insertion tube;
a first imaging element positioned at a distal end of the insertion tube for providing a first visual reference for a health care provider; and
a second imaging element configured to be extended out from and retracted into the lumen of the insertion tube, the second imaging element being movable with respect to the first imaging element so as to provide a health care provider a second visual reference or multiple visual references.

Abstract
A catheter assembly is provided with a first visual device and a second visual device. The second visual device is movable with respect to the first visual device to provide image feedback of a lesion from a different prospective than the first visual device. The second visual device can be moved before, contemporaneously with, or subsequent to a diagnostic or therapeutic procedure. The second visual device can include an elongated tube that can be extended into or retracted out from an insertion tube of the catheter assembly.

24. A method for diagnosing or treating a lesion, comprising
positioning a first catheter assembly in front of a designated lesion; -
capturing a first image of the lesion with a first visual device integrated at a distal end of the first catheter assembly;
extending a second catheter assembly through the first catheter assembly and past the first visual device;
capturing a second image of the lesion with a second visual device integrated near or at a distal end of the second catheter assembly. - View Dependent Claims (25, 26, 27, 28)
