A liquid excipient is added to a lock solution formulation containing a lower alcohol and an anti-coagulant, antibiotic, and/or anti-microbial, such as the ethanol and tri-sodium citrate lock solution formulation, to prevent citrate from crystallizing in catheters made from silicone. The locking solution could include a liquid excipient, such as glycerol, polysorbate-20, or polyethylene glycol (PEG)-400, along with a lower alcohol, such as ethanol, and an anti-coagulant, such as tri-sodium citrate, antibiotic, and/or anti-microbial.

A multi-layer device is provided that is useful in tissue regeneration, for example, for vascular regeneration, e.g., for use in treatment of a coronary vascular disease, such as for treatment of myocardial infarction. A method of making the device also is provided.

The invention describes novel coating agents that include a polymer, one or more latent reactive groups and one or more noncovalent linking groups, the noncovalent linking groups selected to interact with a substrate to which the coating agent is applied. The coating agents are useful for providing a coating that can be further functionalized (for example, by application of additional coating layers), or for providing desirable properties to a surface.

A cardiovascular graft is provided with highly reduced thrombogenicity. The cardiovascular graft is an electrospun non-woven mesh produced from supramolecular polymers with large diameter fibers. The cardiovascular graft can be implemented as a vascular graft into the human body to allow vascular bypass/reconstruction, or repeated venous access for dialysis treatment, as well as other disorders of small-diameter blood vessels.

A coating composition comprises an aqueous solution comprising at least one vinyl carboxylic acid monomer and at least one neutral monomer, wherein the at least one neutral monomer has a glass transition temperature of less than about 100? C. in homopolymeric form. A device comprises a protonated polyacrylate coating, wherein the device is inherently antimicrobial, anti-thrombogenic, flexible, and/or sheds few to no particulates.

A method and device for local delivery of a water-insoluble therapeutic agent to the tissue of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with a non-durable coating which comprises poly(HEMA) complexed with iodine and has a substantially water-insoluble therapeutic agent dispersed therein. The medical disposable device is inserted into a body lumen, and expanded to contact the non-durable coating against the body lumen and deliver the substantially water-insoluble therapeutic agent to the body lumen tissue.
