Heat cured gel and method of making
First Claim
1. A method of forming a non-polymeric gel, comprising:
- providing an oil or oil composition to be cured;
determining an amount of non-polymeric cross-linking desired within the oil or oil composition as a result of curing;
applying heat at a selected temperature for a selected time period based on the determination of amount of non-polymeric cross-linking desired to achieve the desired amount of non-polymeric cross-linking within the oil or oil composition to form the non-polymeric gel;
wherein the oil or oil composition comprises one or more of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), or alpha-linolenic acid (ALA);
wherein the gel further comprises at least one therapeutic agent; and
wherein release of the therapeutic agent from the gel occurs at a predetermined rate.

Abstract
A method of curing and corresponding resulting non-polymeric cross-linked gel are provided. The cross-linked gel can be combined with a medical device structure. The cross-linked gel can provide anti-adhesion characteristics, in addition to improved healing and anti-inflammatory response. The cross-linked gel is generally formed of a naturally occurring oil, or an oil composition formed in part of a naturally occurring oil, that is at least partially cured forming a cross-linked gel derived from at least one fatty acid compound. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent. The curing method can vary the application of heat in both temperature and duration to achieve a desired amount of cross-linking forming the gel.

18. A heat cured non-polymeric gel, comprising:
- a plurality of non-polymeric cross-links resulting from application of heat at a selected temperature for a selected duration to an oil or oil composition to achieve a desired amount of cross-linking to form the non-polymeric gel, wherein the gel further comprises at least one therapeutic agent and the amount of non-polymeric cross-links is controlled by the application of the heat so that the release of the therapeutic agent in the gel occurs at a predetermined desired rate, and wherein the oil or oil composition comprises one or more of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), or alpha-linolenic acid (ALA).

36. A heat cured non-polymeric gel, comprising:
- a plurality of non-polymeric cross-links, wherein the non-polymeric cross-links result from application of heat at a selected temperature for a selected duration to an oil or oil composition to achieve a desired amount of cross-linking to form the non-polymeric gel, wherein the desired amount of cross-linking is selected based on a desired rate of degradation of the gel after the gel is implanted, and wherein the oil or oil composition comprises one or more of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), or alpha-linolenic acid (ALA).
