The present invention is generally directed to materials, gels, coatings and films prepared using a biomaterial (e.g., a fatty acid-based material comprising a network of cross-linked fatty acids) and a fixating material, layer or film (e.g., a fixating material comprising Na-CMC). The materials, gels, coatings and films disclosed herein can be used to facilitate the delivery of one or more therapeutic agents to a targeted tissue and a desired rate of release.

Cured oil-hydrogel biomaterial compositions for controlled drug delivery

The present invention is generally directed to materials, gels, coatings and films prepared using a biomaterial (e.g., a fatty acid-based material comprising a network of cross-linked fatty acids) and a fixating material, layer or film (e.g., a fixating material comprising Na&#x2014;CMC). The materials, gels, coatings and films disclosed herein can be used to facilitate the delivery of one or more therapeutic agents to a targeted tissue and a desired rate of release.

Methods and devices for the provision of a coating on an implantable medical device. The coating includes a bio-absorbable carrier component. In addition to the bio-absorbable carrier component, a therapeutic agent component can also be provided. The methods and devices provide a coating having improved uniformity and coverage which in turn allow for greater control of the amount and dosage of the coating.

Application of a coating on a medical device

A bio-absorbable stand-alone film is derived at least in part from fatty acids. The bio-absorbable stand-alone film can have anti-adhesive, anti-inflammatory, non-inflammatory, and wound healing properties, and can additionally include one or more therapeutic agents incorporated therein. The stand-alone film has one or more perforations or depressions formed therein. Corresponding methods of making the bio-absorbable stand-alone film with one or more perforations or depressions include molding, cutting, carving, puncturing or otherwise suitable methods to create the perforations or depressions in the bio-absorbable stand-alone film. The resulting stand-alone film is bioabsorbable.

Perforated fatty acid films

A method, a kit, and an apparatus provide a coating on an implantable medical device. The apparatus includes housing, a sealed reservoir chamber disposed in the housing, a reducing template, and a reservoir access port. The sealed reservoir contains the coating material. The reducing template is sized to receive a medical device therethrough for application of the coating material. A seal breaching mechanism can be provided and adapted to breach the sealed reservoir upon activation of the apparatus. The reservoir access port, which is disposed in the housing, is adapted to fluidly couple the reducing template with the reservoir chamber upon activation of the apparatus for coating the medical device.

Method and apparatus for application of a fresh coating on a medical device

Devices for the provision of a coating on an implantable medical device are provided. The coating includes a bio-absorbable carrier component. In addition to the bio-absorbable carrier component, a therapeutic agent component can also be provided. The devices provide a coating having improved uniformity and coverage which in turn allow for greater control of the amount and dosage of the coating.

A biomimetic approach utilizing biomolecular self-assembly is described to form nanometer particle size composites for uses, such as, nonlinear optical media. Yeast tRNA was utilized as an ion-exchange/nucleation site within a polymeric matrix (polyacrylamide). Cadmium ion-exchange and subsequent sulfide precipitation resulted in formation of nanometer particle size composites. Illumination of samples with an Argon laster (514 nm) utilizing the Z-scan measurement method resulted in third order nonlinearity &khgr; values of &plus;2.7&times;10 esu.
