Automated tissue welding system and method
View Patent ↗An automated energy irradiator guidance system is disclosed which reduces the potential for human error and improves the consistency and repeatability of tissue welding techniques. The system includes a mapper, a patternizer, an energy director and can additionally include an energy regulator. An interface is included, allowing pattern creation, selection and editing by a user. The system further provides control of energy irradiator parameters for use in tissue welding.
1. A method for automatically directing energy to a target site on a tissue of a living body, comprising:
generating a topographical target site image;
correlating an irradiation pattern with the topographical target site image; and
automatically introducing irradiation energy to the target site in the living body in accordance with the irradiation pattern to weld together native tissue of the living body.
2. The method of claim 1 wherein energy is automatically directed to a target site on a tissue of a living body to secure a graft to the tissue.
3. The method of claim 1 wherein correlating an irradiation pattern with the topographical target site image comprises correlating a two-dimensional irradiation pattern with the topographical target site image.
4. The method of claim 1 wherein correlating an irradiation pattern with the topographical target site image comprises correlating a plurality of irradiation pattern loci in the irradiation pattern with a corresponding plurality of target loci in the topographical target site image.
5. The method of claim 1 wherein automatically introducing irradiation energy comprises correcting for irradiating variables to deliver a selected irradiation dose to each target locus in the topographical target site image.
6. The method of claim 5 wherein automatically introducing irradiation energy includes correcting for an energy spot size of an energy irradiator.
7. The method of claim 5 wherein automatically introducing irradiation energy includes correcting for a distance from an energy transmitter to a target locus in the target site.
8. A method for welding tissue at a weld site in a patient, comprising:
generating a topographical image of the weld site;
correlating an irradiation pattern with the topographical image; and
automatically introducing irradiation energy to the weld site in the patient in accordance with the irradiation pattern.
9. The method of claim 8 wherein correlating an irradiation pattern with the topographical image comprises correlating a two-dimensional irradiation pattern with the topographical target site image.
10. The method of claim 8 wherein correlating an irradiation pattern with the topographical image comprises correlating a plurality of irradiation pattern loci in the irradiation pattern with a corresponding plurality of target loci in the topographical target site image.
11. The method of claim 8 wherein automatically introducing irradiation energy comprises correcting for irradiating variables to deliver a selected irradiation dose to each target locus in the topographical image.
12. The method of claim 11 wherein automatically introducing irradiation energy includes correcting for an energy spot size of an energy transmitter.
13. The method of claim 11 wherein automatically introducing irradiation energy includes correcting for a distance from an energy transmitter to a target locus in the weld site.
14. The method of claim 8 wherein energy is automatically directed to a target site on a tissue of a living body to secure a graft to the tissue.
