Provided is a biocompatible device which has been coated or sealed with a polyether or polyether/carbonate based urethane polymer that contains functional groups (e.g. carboxylic acid groups) which are capable of serving as anchor sites for protein binding.

Polyurethane-sealed biocompatible device and method for its preparation

The present invention provides a method for making an infection-resistant fabricated textile article which is suitable for any in-vivo usage either as a topical bandage, on an implantable configured construct, or as part of a prosthetic mechanical appliance. The method of manufacture applies broadly to any and all fabrics, cloths, gauzes, and/or films comprised in whole or in part of fibers; and provides an infection-resistant textile of valued use in a wide range and variety of medical applications.

Method for making infection-resistant fabricated textile articles for biomedical applications

Disclosed is a treated material including a base material such as an extrudate, a woven fabric, or unwoven fibers, a disperse dye-type molecule such as a dye or antibiotic dispersed within and non-covalently adhered to the base material, and a molecule-of-interest immobilized on the base material by way of a reactive group on the disperse dye-type molecule. Also disclosed are methods of producing the treated material.

Anthraquinone dye treated materials

Disclosed is a biocompatible, thromboresistant substance useful for implantable and extracorpeoreal devices in contact with the vascular system, and methods for producing the same. The biocompatible, thromboresistant substance comprises a synthetic, biocompatible material, at least one biocompatible base coat layer adhered to at least one surface of the material, and a thrombogenesis inhibitor immobilized on the base coat layer via a component capable of binding the inhibitor. The thrombogenesis inhibitor is hirudin, or an active analog or fragment thereof.

Hirudin-coated biocompatible substance

Disclosed is a biocompatible, thromboresistant substance useful for implantable and extracorporeal devices in contact with the vascular system, and methods for producing the same. The biocompatible, thromboresistant substance comprises a synthetic, biocompatible material, at least one biocompatible base coat layer adhered to at least one surface of the material, and the thrombogenesis inhibitor thrombomodulin immobilized on the base coat layer via a component capable of binding the inhibitor without affecting its thrombogenesis-inhibiting activity.

Thrombomodulin-coated bicompatible substance

Disclosed is a soluble, biocompatible, pharmacological agent for inhibiting thrombin generation and thrombus formation, and methods for producing the same. The pharmacological agent or conjugate includes a soluble, biocompatible carrier and a thrombogenesis inhibitor immobilized thereto via the carrier which binds the inhibitor. The thrombogenesis inhibitor is hirudin, or an active analog or active fragment thereof. The thrombogenesis inhibitor may be bound to the carrier via a bifunctional cross-linking reagent.

Soluble hirudin conjugates

Disclosed is a biocompatible, thromboresistant substance useful for implantable and extracorporeal devices in contact with the vascular system, and methods for producing the same. The biocompatible, thromboresistant substance comprises a synthetic, biocompatible material, at least one biocompatible base coat layer adhered to at least one surface of the material, and a thrombogenesis inhibitor immobilized on the base coat layer via a component capable of binding the inhibitor. The thrombogenesis inhibitor is streptokinase, urokinase, tissue plasminogen activator, ATPase, 5'-nucleotidase, and active fragments and active analogs thereof.
