- LOW-SWELLING HYDROGEL SEALANTS FOR WOUND REPAIR
-
One aspect of the present invention relates to a sealant comprising dendrimeric macromolecules that form a hydrogel. In certain instances, the sealants of the invention comprise a hydrogel that swells less than about 400 wt% upon hydration. In certain instances, the sealants of the present invention further comprise a pharmaceutical agent, such as an antibiotic, antimicrobial agent, or antiinflammatory agent. The sealants of the present invention may be used to treat a wound on a patient that is topical or in vivo. In addition, the sealants of the present invention can act as a barrier to bacteria and other organisms. Another aspect of the present invention relates to a method of sealing a wound on a patient comprising the steps of applying an effective amount of a dendrimeric compound to a wound on a patient and treating the dendrimeric compound with a polymerization agent. Another aspect of the present invention relates to a method of sealing a wound on a patient comprising the steps of treating a dendrimeric compound with a polymerization agent to form a repair agent, and applying the repair agent to a wound on a patient. Another aspect of the present invention relates to a kit for sealing a wound comprising a polymerizable dendrimeric compound that forms a hydrogel and a system for delivering the polymerizable dendrimeric compound to a wound on a patient.

- DENTRITIC POLYMERS, CROSSLINKED GELS, AND THEIR USES IN ORTHOPEDIC APPLICATIONS
-
The present invention provides compositions, kits, and methods for repairing cartilaginous tissue. Certain methods of the invention utilize dendritic macromolecules formed by treating a dendritic compound with light or a linking compound. In certain instances, the dendritic compounds have a lysine, cysteine, isocysteine residue or other nucleophilic group attached to their peripheries. Addition of a compound containing two or more electrophilic groups, such as aldehydes, activated esters, or acrylates, to the lysine-capped, cysteine-capped, or isocysteine-capped dendrimers produces a polymeric compound that can repair a cartilage defect.

- DENDRITIC POLYMERS, CROSSLINKED GELS, AND THEIR USES AS OPHTHALMIC SEALANTS AND LENSES
-
The present invention provides compositions and methods for sealing a wound and preparing a lens. The methods of the invention utilize dendritic macromolecules formed by treating a dendritic compound with light or a linking compound. In certain instances, the dendritic compounds have a lysine-, cysteine-, isocysteine-residue or other nucleophilic group attached to the periphery of the dendrimer: Addition of a compound containing two or more electrophilic groups such as aldehydes, activated esters, or acrylates to the lysine-, cysteine-, or isocysteine-capped dendrimers produces a polymeric compound that can form a seal or a lens. Another aspect of the invention relates to a method of treating disease using the pharmaceutical compositions of the invention. Other aspects of the invention relate to kits for sealing a wound or preparing a lens, delivery devices, and methods for controlling the polymerization of a hydrogel system.

- Dendritic macromers as in situ polymerizing biomaterials for securing cataract incisions
-
Dendritic macromers are attractive macromolecules for hydrogel formation since high cross-linking densities at low polymer concentration can be obtained, varied physical properties can be observed based on the macromer structure, and low viscous aqueous s
