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.

Claims (23)

1. A system for processing a tubular member comprising:

a hollow tubular member including a wall having a proximal end, a distal end, an inner surface, an outer surface, and a lumen therein;

a laser source for transmitting laser energy onto the outer surface of the hollow tubular member;

an inner tubular member positioned within the lumen of the hollow tubular member, the inner tubular member having a proximal end, a distal end, an inner surface, an outer surface, and a lumen therein, wherein the proximal and distal ends of the inner tubular member are oriented in a same direction as the proximal and distal ends of the hollow tubular member;

a first media flow disposed in an annular lumen defined between the inner surface of the hollow tubular member and the outer surface of the inner tubular member, the first media flow flowing from the proximal end to the distal end; and

a second media flow disposed in the lumen of the inner tubular member flowing from the proximal end to the distal end.

2. The system of claim 1 , wherein the first media flow comprises a gas.

3. The system of claim 1 , wherein the first media flow comprises a liquid.

4. The system of claim 1 , wherein the second media flow comprises a gas.

5. The system of claim 1 , wherein the second media flow comprises a liquid.

6. The system of claim 2 , wherein the second media flow comprises a liquid.

7. The system of claim 3 , wherein the second media flow comprises a gas.

8. The system of claim 1 , wherein the first media flow includes a solution having a degree of energy reflecting characteristics.

9. The system of claim 1 , wherein the first media flow includes a solution having a degree of energy absorbing characteristics.

10. The system of claim 1 , wherein the laser energy is transferred through a column of fluid.

11. A system for processing a tubular member comprising:

an outer tubular member including a wall having an inner surface, an outer surface, and a lumen therein;

an inner tubular member disposed in the lumen of the outer tubular member, the inner tubular member including a wall having an inner surface, an outer surface, and a lumen therein;

an annular lumen defined between the inner surface of the outer tubular member and the outer surface of the inner tubular member;

a laser source for transmitting laser energy through a fluid stream onto the outer surface of the outer tubular member, the laser source being configured to form a predetermined pattern through at least a portion of the wall of the outer tubular member;

a first fluid column disposed in the annular lumen; and

a second fluid column disposed in the lumen of the inner tubular member, and wherein the second fluid column comprises a gas.

12. The system of claim 11 , wherein the second fluid column comprises a liquid.
