Abstract
The disclosure relates to a device for use in removing undesired material, e.g., an occlusion or plaque, from a duct or blood vessel within a patient's body. The device comprises a catheter adapted to be disposed within a duct and having a distal end portion with a tip and a tapered surface extending from the tip to the side of the catheter. The catheter has a lumen extending through the length thereof. The intersection of the lumen and the tapered surface forming an elongated opening. Pulsed laser energy is applied by an optical fiber extending through the lumen to the elongated openings and thereby the undesired material. An inflatable bladder is provided for positioning the distal end portion of the catheter adjacent the inner surface of the duct to position the elongated opening adjacent the undesired material to be removed. A filament extending through the catheter and connected to the distal end portion can be rotated at the proximal end of the catheter to rotatably position the distal portion thereof.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
