1. A method of joining or reconstructing biological tissue, said method comprising the following steps:
- providing a solid filler material in the form of a preformed sheet, wherein the sheet comprises collagen, gelatin, or a mixture thereof;
placing the filler material over said biological tissue prior to applying energy, andapplying radiofrequency or optical energy to the filler material in an amount sufficient to melt or denature the filler material while said filler material is over the said biological tissue.

Abstract
A method for joining or reconstructing biological tissue comprises providing a solid filler material in the form of a preformed sheet, where the sheet comprises collagen, gelatin or a mixture thereof. The filler material is placed over tissue. Radiofrequency energy or optical energy is thereafter applied to the filler material in an amount sufficient to melt or denature the filler material.

5. A method of joining or restructuring biological tissue, said method comprising the following steps:
-
providing a filler material in the form of a preformed sheet which fuses to said biological tissue upon the application of energy, wherein the filler material comprises collagen, gelatin, or a mixture thereof; placing the filler material over said biological tissue to be joined or restructured prior to applying energy; and applying radiofrequency energy to the filler material in an amount sufficient to melt or denature the filler material and the said biological tissue after said filler material has been placed over the said biological tissue, wherein the radiofrequency energy is applied from an inert gas beam radiofrequency device. - View Dependent Claims (6, 7)

- 8. An improved method for joining or reconstructing biological tissue wherein a collagen- or gelatin-containing material is placed over the tissue and energy is thereafter applied to fuse the material and tissue together, wherein the improvement comprises the step of applying radiofrequency energy to the material and said tissue under conditions which result in about 20 to 1800 joules of energy being delivered to the collagen or gelatin-containing material and the said tissue.
