Abstract
Disclosed is a system provided with cooling fluid for interstitial laser therapy that limits and/or provides control of the laser ablation zone produced by a device for interstitial laser therapy, which allows for better control of the laser ablation zone and more predictive and accurate interstitial laser therapy. The device for interstitial laser therapy includes an optical waveguide having an optical output end and an optical diffuser optically coupled to, optically associated with, or positioned about the optical output end. An irrigation tube directs cooling fluid to flow out of a distal end of the irrigation tube which directs cooling fluid to flow inside of and/or outside of the optical diffuser.
Claims26
A system for interstitial laser therapy comprising:
- a device for interstitial laser therapy comprising:
- an optical waveguide having an optical output end;
- and,
- an optical diffuser positioned over the optical output end of the optical waveguide, wherein the optical diffuser is provided with one or more optical diffuser apertures;
- and,
- an irrigation tube positioned over at least part of the optical waveguide, the irrigation tube able to direct a cooling fluid to flow out of an end of the irrigation tube, wherein the optical diffuser is positioned internal to at least part of the irrigation tube.
A system for interstitial laser therapy comprising:
- a device for interstitial laser therapy comprising:
- an optical waveguide having an optical output end;
- and
- an optical diffuser positioned over the optical output end of the optical waveguide, wherein the optical diffuser is provided with one or more optical diffuser apertures;
- and
- an irrigation tube positioned over at least part of the optical waveguide, the irrigation tube able to direct a cooling fluid to flow out of an end of the irrigation tube, wherein a fixed power of laser light is transmitted in the optical waveguide and a rate of ablation is controlled by controlling a flow of the cooling fluid.
A system for interstitial laser therapy comprising:
- a device for interstitial laser therapy comprising:
- an optical waveguide having an optical output end;
- and
- an optical diffuser positioned over the optical output end of the optical waveguide, wherein the optical diffuser is provided with one or more optical diffuser apertures;
- an irrigation tube positioned over at least part of the optical waveguide, the irrigation tube able to direct a cooling fluid to flow out of an end of the irrigation tube;
- and
