| 6066325 | Fragmented polymeric compositions and methods for their use Cross-linked hydrogels comprise a variety of biologic and non-biologic polymers, such as proteins, polysaccharides, and synthetic polymers. Such hydrogels preferably have no free aqueous phase and may be applied to target sites in a patient's body by extr... | 05/23/2000 |
| 6063061 | Fragmented polymeric compositions and methods for their use Molecular cross-linked gels comprise a variety of biologic and non-biologic polymers, such as proteins, polysaccharides, and synthetic polymers. Such molecular gels may be applied to target sites in a patient's body by extruding the gel through an orifice... | 05/16/2000 |
| 6007613 | Bioadhesive; preparation procedure and device for the application of a bioadhesive; and hardeners for a bioadhesive The present invention relates to a bioadhesive that includes at least two constituents that are intended to be combined, for simultaneous, separate, or time-shifted use, i.e.: 1) a semi-liquid constituent (A) that includes, at a minimum, gelatin in an aqu... | 12/28/1999 |
| 5957166 | Method and apparatus for dispersing fluid into a material A fluid dispersion and delivery assembly (16) includes first and second syringes (18,20) containing a first, fluid material (32) and a second material (34), fluidly coupled together at their distal ends (22,24) by a fluid transfer assembly (2). The fluid ... | 09/28/1999 |
| 5931165 | Films having improved characteristics and methods for their preparation and use Gelatin film compositions are useful for immobilization over tissue, usually by the application of energy to the films. Exemplary films comprise cross-linked and non-cross-linked granular and non-granular gelatin sheets, typically including a plasticizer.... | 08/03/1999 |
| 5908054 | Fluid dispersion and delivery assembly and method A fluid dispersion and delivery assembly (49) includes first and second syringes (28,50) containing a hemostatic solution (38) and a flowable gel material (58), fluidly coupled together by a fluid transfer assembly (2). The fluid transfer assembly include... | 06/01/1999 |
| 5895412 | Device and method for sealing tissue An apparatus and method for effecting and enhancing wound closure in tissue is disclosed. Wounds and tissue are sealed by heating a sealant material, such as collagen, in an applicator (10) to a temperature sufficient to melt the sealant. The melted seala... | 04/20/1999 |
| 5824015 | Method for welding biological tissue 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. Radiofreque... | 10/20/1998 |
| 5791352 | Methods and compositions for inhibiting tissue adhesion Tissue adhesions are inhibited by applying and immobilizing a solid preformed matrix material over a target region, such as a surgical site, in a first tissue surface. The matrix material may be any continuous solid material, such as a sheet or film. Afte... | 08/11/1998 |
| 5749895 | Method for bonding or fusion of biological tissue and material Biological materials are joined, repaired or fused by heating the material in proximity to a mechanical support. Preferably, the mechanical support comprises a patch or bridge structure. In the most preferred embodiment, the patch is formed from collagen ... | 05/12/1998 |
| 5690675 | Methods for sealing of staples and other fasteners in tissue 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, fibrino... | 11/25/1997 |
| 5669934 | Methods for joining tissue by applying radiofrequency energy to performed collagen films and sheets A method for joining or restructuring tissue consists essentially of providing a preformed film or sheet of a solid filler material which fuses to tissue upon the application of energy. The material comprises collagen, gelatin, mixtures thereof, optionall... | 09/23/1997 |
