Abstract

A UV curing resin injection apparatus for treating an aneurysm, includes a catheter, a light transmission tube disposed at an inner side of the catheter to transmit UV light, and a connection tube disposed at the inner side of the catheter to be spaced from the light transmission tube and configured to transfer a UV curing resin, wherein the light transmission tube is formed independently from the connection tube.

Claims

1. A UV curing resin injection apparatus for treating aneurysm, comprising:

a catheter;

a light transmission tube extending inside the catheter and configured to transmit light beams therethrough; and

a resin transfer tube extending inside the catheter and configured to transfer uncured resin therethrough,

wherein the resin transfer tube and the light transmission tube are independently formed and spaced from each other inside the catheter

2. The apparatus of claim 1, wherein the light transmission tube comprises an optical fiber, wherein one end of the light transmission tube protrudes out of the catheter, wherein the other end of the light transmission tube is operably linked to a UV source for receiving UV light beams therefrom.

3. The apparatus of claim 2, wherein the catheter comprises a channel formed through the catheter, wherein the light transmission tube extends inside the channel.

4. The apparatus of claim 3, wherein the light transmission tube is movable relative to the channel of the catheter.

5. The apparatus of claim 1, further comprises a nozzle provided at one end of the resin transfer tube, wherein the other end of the resin transfer tube is in communication with a uncured resin supply.

6. The apparatus of claim 5, wherein the uncured resin supply comprises a pump.

7. The apparatus of claim 5, wherein the nozzle comprises a plurality of injection orifices.

8. The apparatus of claim 7, wherein at least part of the plurality of injection orifices have different diameters from each other.

9. The apparatus of claim 1, wherein the resin transfer tube is coated with a UV blocking material.

10. The apparatus of claim 1, further comprising:

a balloon connected to the catheter and

a balloon-inflating fluid tube extending inside the catheter and in communication with the balloon.

11. The apparatus of claim 1, wherein the light transmission tube comprises a distal end portion extending outside the catheter, the resin transfer tube comprises a distal end portion extending outside the catheter.

12. The apparatus of claim 11, wherein the distal end portions of the light transmission tube and the resin transfer tube are coupled by a coupling member disposed therebetween.

13. The apparatus of claim 11, further comprising a reflective surface provided in the distal end portion of the light transmission tube, wherein the reflective surface is inclined relative to a direction of elongation of the light transmission tube such that the light beams reaching the reflective surface are directed toward the distal end portion of the resin transfer tube.

14. The apparatus of claim 13, wherein the reflective surface comprises a reflective coating.

15. The apparatus of claim 13, wherein the distal end portion of the resin transfer tube is configured to receive light beams from the light transmission tube such that the uncured resin in the distal end portion of the resin transfer tube is exposed to the light beams and begin curing prior to being discharged from the distal end portion of the resin transfer tube.

16. The apparatus of claim 15, further comprising a light blocking member movably placed over an outer circumference of the distal end portion of the resin transfer tube, wherein the light blocking member is configured to block light beams from the distal end portion of the light transmission tube, wherein the light blocking member is configured to slide over the outer circumference of the distal end portion of the resin transfer tube such that exposure to the light beams of the uncured resin inside the distal portion of the resin transfer tube can be adjusted.

17. The apparatus of claim 11, further comprising a light blocking member disposed over an outer circumferential area of the distal end portion of the resin transfer tube where a nozzle is provided.

18. The apparatus of claim 11, further comprising a plurality of micro-protrusions formed on an outer circumferential surface of the distal end portion of the resin transfer tube.

19. A system comprising:

the apparatus of claim 1;

a stent to use with the apparatus, the stent comprising a plurality of wave-shaped modules, wherein the apparatus is to be placed at an inner side or an outer side of the stent.
