ANTI-THROMBOGENIC COATING
An example medical device includes a vascular device, such as a catheter, and an anti-thrombogenic coating on a surface of the vascular device, such as a surface likely to contact blood. The anti-thrombogenic coating includes one or more peptides configured to interact with fibrinogen in the blood, such as a first type of peptides configured to bind to fibrinogen a second type of peptides configured to inhibit conversion of fibrinogen to fibrin. The anti-thrombogenic coating also includes a polymer, such as a hydrocolloid polymer, a tunable polyethylene glycol (PEG), or other controlled release polymer configured to control release of the one or more peptides and maintain a concentration of the peptides at the surface of the anti-thrombogenic coating above a minimum inhibitory concentration, thereby inhibiting thrombin formation on the intravascular medical device.
Method for use of a double-structured tissue implant for treatment of tissue
A method for use of a double-structured tissue implant or a secondary scaffold stand-alone implant for treatment of tissue defects. The double-structured tissue implant comprising a primary scaffold and a secondary scaffold consisting of a soluble collagen solution in combination with a non-ionic surfactant generated and positioned within the primary scaffold. A method of use of a stand-alone secondary scaffold implant or unit for treatment of tissue defects.
Polytetrafluoroethylene co-polymer emulsions
The present disclosure is directed to a class of fluorinated copolymers, such as PTFE copolymers, that can be dissolved in low toxicity solvents, such as Class III Solvents, and that enable the creation of stable water-in-solvent emulsions comprising the fluorinated copolymers dissolved in a low toxicity solvents and a hydrophilic agent (e.g., a therapeutic agent) dissolved in an aqueous solvent, such as water or saline.
BIO-FILM RESISTANT SURFACES
The present invention relates to methods and compositions for rendering a surface resistant to bio-film formation by a combination of an antimicrobial agent, an organic hydroxy acid, lubricious biomedical polymer and solvent. The invention provides for compositions which may be used to render surfaces bio-film resistant, articles having bio-film resistant surfaces, and methods for their preparation. The present invention may be advantageously applied to medical articles as well as articles used in non-medical contexts, such as child care or food preparation.

Further a method for treating proliferative diseases by delivering a combination of at least two pharmaceutically active agents to a diseased area or tissue comprising: a coating layer of two hydrophobic drugs applied to an exterior surface of a medical device or substrate and a polymer blend carrier for the pharmaceutically active agents.
Porous orthopedic materials coated with demineralized bone matrix
A biomaterial including a porous biocompatible structure having interconnected pores, wherein the pores have interior walls and are interconnected by passageways, the interior walls and passageways being coated with an osteoinductive aqueous demineralized bone extract solution, the aqueous demineralized bone extract solution including growth factors, proteins, a demineralized bone matrix and at least one of a weak acid and a guanidine hydrochloride, wherein the demineralized bone matrix is present per 100 g of the solution in an amount of from about 2 g to about 10 g.
Operating room coating applicator and method
The present disclosure provides a coating applicator operable to apply a coating of a therapeutic agent upon an object comprising an openable and sealable device compartment, a therapeutic agent positioned in communication with the device compartment, an atomizer operable to atomize the therapeutic agent, and a source of vacuum in communication with the device compartment. The coating applicator may further comprise a drier, and the drier may comprise an arrangement to operate the source of vacuum for a time sufficient to promote drying of applied therapeutic agent. Deposition of the atomized therapeutic agent may be promoted by contacting the atomized therapeutic agent while the object is in a chilled condition and by contacting the object with atomized therapeutic agent while the atomized therapeutic agent is in a heated condition. Related methods are also disclosed.
COATED BALLOON CATHETER AND COMPOSITION FOR COATING SAID BALLOON CATHETER
The invention relates to a coated balloon catheter with a catheter substrate and a coating on the catheter substrate. The coating comprises a pharmaceutically active ingredient embedded in a binder matrix.
