Abstract
Wounds in lung tissue are closed in a two step method consisting essentially of applying fasteners to a region adjacent to the wound, wherein the fasteners may cause penetrations. The fasteners are present in a preformed layer of collagen, fibrin, fibrinogen, elastin, albumin, or a combination thereof, and energy is applied to the region to fuse the material to the tissue and seal perforations in the tissue.
Claims14
A method for closing a wound in tissue, said method consisting essentially of the following two steps performed sequentially:
- applying fasteners selected from the group consisting of staples, clips, pins, hooks, and suture to a region adjacent to the wound to close the wound, wherein the fasteners cause penetrations in the tissue and the fasteners are present in a preformed layer of a material selected from the group consisting of collagen, fibrin, fibrinogen, elastin, albumin, and combinations, thereof, which fuses to the tissue upon the application of energy;
- and
- applying energy selected from the heat, radiofrequency, laser, ultrasonic, and electrical energy to the region to fuse the material to the tissue and seal perforations in the tissue.
A method for sealing a resection line in lung tissue, said method consisting essentially of the following two steps performed sequentially:
- applying along the resection line fasteners selected from the group consisting of staples, clips, pins, hooks, and suture to close the lung tissue, wherein the fasteners are present in a preformed layer of a material selected from the group consisting of collagen, fibrin, fibrinogen, elastin, albumin, and combinations thereof, which fuses to the lung tissue upon the application of energy;
- and
- applying energy selected from the heat, radiofrequency, laser, ultrasonic, and electrical enerqy to the region to fuse the material to the tissue and seal perforations in the tissue.
