Abstract

Biocompatible compositions are provided which may include at least one polysaccharide, at least one salt, and at least one reactive component. The at least one polysaccharide, at least one salt, and at least one reactive component may be in a single solution or multiple solutions and combined utilizing means within the purview of those skilled in the art. The compositions of the present disclosure experience delayed gelation, permitting their manipulation after application to tissue, which may be desirable for certain surgical and/or medical procedures, including cosmetic surgery.

Claims

1. A composition comprising:

at least one polysaccharide, optionally in solution;

at least one salt, optionally in solution; and

at least one reactive component, optionally in solution,

wherein at least one of the polysaccharide, salt and reactive component are in a solution, and wherein the composition forms a gel from about 3 hours to about 5 hours after the at least one polysaccharide, at least one salt, and at least one reactive component have been combined.

2. The composition of claim 1, wherein the at least one polysaccharide is selected from the group consisting of alginates, sulfates, celluloses, and combinations thereof.

3. The composition of claim 1, wherein the at least one polysaccharide is in a solution at a concentration of from about 0.1% by weight to about 10% by weight.

4. The composition of claim 1, wherein the at least one salt is selected from the group consisting of carbonates, bicarbonates, sulfites, phosphates, sulfates, and combinations thereof.

5. The composition of claim 1, wherein the at least one salt is in a solution at a concentration of from about 0.1% by weight to about 10% by weight.

6. The composition of claim 1, wherein the at least one reactive component comprises genipin.

7. The composition of claim 1, wherein the at least one reactive component is in a solution at a concentration of from about 0.001% by weight to about 10% by weight.

8. The composition of claim 1, wherein the at least one polysaccharide comprises sodium alginate, the at least one salt comprises calcium carbonate, and the at least one reactive component comprises genipin.

9. The composition of claim 1, further comprising at least one bioactive agent selected from the group consisting of anti-adhesives, antimicrobials, anti-infectives, anti-thrombotics, analgesics, antipyretics, anesthetics, antiepileptics, antihistamines, anti-inflammatories, anti-proliferatives, cardiovascular drugs, diagnostic agents, chemo agents, telomerase inhibitors, polymer drugs, anti-platelet drugs, platelet activating drugs, angiogenic agents, gene therapy agents, protein therapeutics, sympathomimetics, cholinomimetics, antimuscarinics, antispasmodics, hormones, growth factors, muscle relaxants, adrenergic neuron blockers, antineoplastics, immunogenic agents, immunosuppressants, gastrointestinal drugs, diuretics, steroids, lipids, lipopolysaccharides, polysaccharides, enzymes, and combinations thereof.

10. A method comprising:

contacting tissue with at least one polysaccharide, at least one salt, and at least one reactive component; and

allowing the at least one polysaccharide, at least one salt, and at least one reactive component to form a gel,

wherein the gel forms from about 3 hours to about 5 hours after the at least one polysaccharide, at least one salt, and at least one reactive component have been combined.

11. The method of claim 10, wherein the at least one polysaccharide is selected from the group consisting of alginates, sulfates, celluloses, and combinations thereof.
