Benefits of technology
[0018] The present invention is directed to a variety of embodiments. In at least one embodiment the invention is directed to a system for cutting and / or processing a hollow tube. The system of the present embodiment utilizes a hybrid laser / water jet mechanism to direct laser energy to the tube. The system also employs an mechanism for injecting a media such as gas, fluid, etc, through the hollow tube in order to disrupt and / or prevent the formation of the water column within the tube. Such a disruption, results in deflection of the laser energy, thereby preventing the laser energy from reaching, and thus damaging, the opposite inside wall of the tube.
Problems solved by technology
Such a disruption, results in deflection of the laser energy, thereby preventing the laser energy from reaching, and thus damaging, the opposite inside wall of the tube.

Abstract
A system and method for processing a tubular member comprises a hollow tubular member, a laser and a media flow. The laser is constructed and arranged to transmit laser energy to the tubular member. The laser energy is transmitted to the tubular member through a fluid column according to a predetermined pattern. The media flow is injected into the lumen of the hollow tubular member.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Not Applicable STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH [0002] Not Applicable BACKGROUND OF THE INVENTION [0003] A stent is a radially expandable endoprosthesis which is adapted to be implanted in a body lumen. Stents are typically used in the treatment of atherosclerotic stenosis in blood vessels and the like to reinforce body vessels and to prevent restenosis following angioplasty in the vascular system. They have also been implanted in urinary tracts, bile ducts and other bodily lumen. They may be self-expanding or expanded by an internal radial force, such as when mounted on a balloon. [0004] Delivery and implantation of a stent is accomplished by disposing the stent about a distal portion of the catheter, percutaneously inserting the distal portion of the catheter in a bodily vessel, advancing the catheter in the bodily lumen to a desired location, expanding the stent and removing the catheter from the lumen. In the case of...
