Guidewire tipped laser fiber
View Patent ↗A device for application of energy within a tubular bodily structure including an optical fiber couplable to a source of laser energy and a guidewire tip. The optical fiber has a laser emitting portion remote from the source of laser energy and a distal end. The guidewire tip is operably secured to the optical fiber and extends distally outwardly away from the distal end of the optical fiber. The guidewire tip assists in advancing the device through the tubular bodily structure.
1. A device for application of energy within a tubular bodily structure, comprising:
an optical fiber couplable to a source of laser energy at a proximal end of the optical fiber, the optical fiber having a laser emitting portion that is located remotely from the source of laser energy and the optical fiber also having a distal end, the laser emitting portion and the distal end being enclosed in a tip sleeve having openings therein; and
a metallic guidewire tip operably secured to the optical fiber via the tip sleeve and extending distally outwardly away from and distally beyond the distal end of the optical fiber whereby the guidewire tip assists in advancing the device through the tubular bodily structure.
2. The device as claimed in claim 1 , wherein the tip sleeve is operably secured to and at least partially surrounding the distal end of the optical fiber.
3. The device as claimed in claim 2 , wherein the guidewire tip is operably coupled to the tip sleeve.
4. The device as claimed in claim 2 , wherein the tip sleeve comprises a generally cylindrical body having at least one opening therein.
5. The device as claimed in claim 1 , further comprising an insulative tip shield at least partially surrounding the laser emitting portion.
6. The device as claimed in claim 1 , wherein the guidewire tip is curved.
7. A method of insertion and advancement of a device for application of energy within a tubular bodily structure, comprising:
accessing the tubular bodily structure;
coupling an optical fiber to a source of laser energy, the optical fiber having a laser emitting portion remote from the source of laser energy and a distal end both enclosed in a tip sleeve having openings therein; and
advancing a guidewire tip operably secured to the optical fiber via the tip sleeve and extending distally outwardly away from and distally beyond the distal end of the optical fiber into and through the tubular bodily structure without use of a catheter.
8. The method as claimed in claim 7 , wherein accessing the tubular bodily structure further comprises cutting down surgically to the tubular bodily structure.
9. The method as claimed in claim 7 , wherein accessing the tubular bodily structure further comprises inserting a hollow needle into the tubular bodily structure.
10. A device for application of energy within a tubular bodily structure, comprising:
an optical fiber couplable to a source of laser energy, the optical fiber having a laser emitting portion remote from the source of laser energy and the optical fiber also having a distal end, the laser emitting portion and the distal end being enclosed in a tip sleeve having openings therein; and
means for guiding that are operably secured to the optical fiber via the tip sleeve and that extend distally outwardly away from the distal end of the optical fiber whereby the means for guiding assists in advancing the device through the tubular bodily structure.
11. The device as claimed in claim 10 , wherein the tip sleeve comprises a generally cylindrical body having at least one opening therein.
12. The device as claimed in claim 10 , further comprising means for insulating at least partially surrounding the laser emitting portion.
13. The device as claimed in claim 10 , wherein the means for guiding is curved.
14. A device for application of energy within a tubular bodily structure, comprising:
an optical fiber couplable to a source of laser energy, the optical fiber having a laser emitting portion remote from the source of laser energy and the optical fiber also having a distal end, the laser emitting portion and the distal end being enclosed in a tip sleeve having openings therein; and
a resiliently flexible guidewire portion operably secured to the optical fiber via the tip sleeve and extending distally outwardly away from and distally beyond the distal end of the optical fiber whereby the flexible guide portion assists in advancing the device through the tubular bodily structure.
15. The device as claimed in claim 14 , wherein the tip sleeve member is operably secured to and at least partially surrounds the distal end of the optical fiber.
16. The device as claimed in claim 15 , wherein the sleeve member comprises a generally cylindrical body having at least one opening therein.
17. The device as claimed in claim 14 , further comprising an insulative tip shield at least partially surrounding the laser emitting portion.
18. The device as claimed in claim 14 , wherein the resilient guidewire portion is curved.
