摘要:
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.

Disclosed are vascular grafts including an expanded copolymer of tetrafluoroethylene (TFE) and perfluoropropylene vinyl ether (PPVE). In certain embodiments, the copolymer includes between about 0.01% and about 1.5% PPVE. Vascular grafts exhibit superior performance properties, e.g., radial strength, and suture strength, and manufacturing properties, e.g., sinter time. Methods of forming vascular grafts from the copolymer also are described.

A barrier layer and corresponding method of making provide anti-inflammatory, non-inflammatory, and anti-adhesion functionality for a medical device implantable in a patient. The barrier layer can be combined with a medical device structure to provide anti-adhesion characteristics, in addition to improved healing, non-inflammatory, and anti-inflammatory response. The barrier layer 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. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent.
摘要:
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.

摘要:
A non-polymeric or biological coating applied to a radially expandable interventional medical device in a collapsed, wrapped, or folded configuration. Properties of the coating material applied to the medical device are adjusted or varied to result in a desired combination of coverage of the surface of the medical device, drug loading, and coating thickness. The coating is sterile, and is capable of being carried by a sterile medical device to a targeted tissue location within the body following radial expansion. The therapeutic coating transfers off the medical device due in part to a biological attraction with the tissue and in part to a physical transference from the medical device to the targeted tissue location in contact with the medical device.
摘要:
A barrier device is formed of a barrier component that can exhibit anti-inflammatory properties, non-inflammatory properties, and/or adhesion-limiting properties, as well as generate a modulated healing effect on injured tissue. The barrier component can be a non-polymeric cross-linked gel derived at least in part from a fatty acid compound, and may include a therapeutic agent. The barrier device can have anchoring locations to provide an area on the barrier device to interface with an anchoring mechanism. The anchoring locations can include openings and/or anchor elements. The barrier device can also include truss structures that provide additional strength to the barrier component. The barrier device is implantable in a patient for short term or long term applications, and can include controlled release of the therapeutic agent.
摘要:
Fatty acid-derived biomaterials, methods of making the biomaterials, and methods of using them as drug delivery carriers are described. The fatty acid-derived biomaterials can be utilized alone or in combination with a medical device for the release and local delivery of one or more therapeutic agents. Methods of forming and tailoring the properties of said biomaterials and methods of using said biomaterials for treating injury in a mammal are also provided.
