Abstract:
An inhibitor of FXII/FXIla for the prevention of the formation and/or stabilization of thrombi during and/or after a medical procedure performed on a human or animal subject comprising contacting blood of said human or animal subject with artificial surfaces, wherein said inhibitor of FXII/FXIla is administered before and/or during and/or after said medical procedure.
Abstract:
The present invention relates to immobilized biologically active entities that retain a significant biological activity following manipulation. The invention also comprises a medical substrate comprising a heparin entity bound onto a substrate via at least one heparin molecule, wherein said bound heparin entity is heparinase-1 sensitive.
Abstract:
Disclosed are optimized keratin preparations for use in medical applications. Methods to produce optimized keratin preparations are provided for use in biomedical applications, particularly for the treatment of bleeding, and for the treatment of wounds. Also disclosed are surgical or paramedic aids comprising a substrate with keratin preparations provided thereon, and kits comprising keratin derivatives packaged in sterile form.
Abstract:
Cardiovascular cell proliferation in a blood vessel subjected to trauma, such as angioplasty, vascular graft, anastomosis, or organ transplant, can be inhibited by contacting the vessel with a polymer consisting of from 6 to about 30 amino acid subunits, where at least 50 % of the subunits are arginine, and the polymer contains at least six contiguous arginine subunits. Exemplary polymers for this purpose include arginine homopolymers 7 to 15 subunits in length.
Abstract:
Ion-implanted protein-coated occlusion coils are described which have essentially the same dimensions as untreated coils and exhibit altered surface properties, e.g., thrombogenicity, endothelial cellular migration and adhesion, relative to untreated coils thus making them particularly useful in treating wide-necked brain aneurysms.
Abstract:
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 a component of 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 component of the carrier via a bifunctional cross-linking reagent.
Abstract:
The present invention relates to immobilized biologically active entities that retain a significant biological activity following manipulation. The invention also comprises a medical substrate comprising a heparin entity bound onto a substrate via at least one heparin molecule, wherein said bound heparin entity is heparinase-1 sensitive.
Abstract:
Restenosis in a subject can be treated by administering to a tissue, e.g., a blood vessel, of the subject an agent that increases SERCA activity. For example, a stent that is coated with the agent can be introduced into a blood vessel.
Abstract:
The invention relates to hemocompatible surfaces, characterized in that they contain materials and that components of the outer layer of blood cells and/or mesothelial cells are deposited on and/or introduced into the surface of said materials. The invention also relates to a method for preparing hemocompatible surfaces and to their use in numerous areas of the health sector, such as medicine, dentistry, surgery, cosmetics or in fields relating to blood, tissue and/or other body fluids.
Abstract:
The present invention is related to a method for preventing the clogging of medicinal drainage or ventilation tubes, comprising coating the surface of said ventilation tubes with anticlogging substances, especially human serum albumin. The medicinal ventilation tubes are rigid, semirigid and/or elastic tubes, such as tympanostomy tubes, paranasal sinus drainage tubes, thracheostomy tubes, gastric tubes, urinary catheters, wound drains and voice prosthesis tubes made of plastics, silicons, metals, hydroxylapatits, etc. The use of the anticlogging substances for manufacturing surface coated medicinal ventilation tubes for treatment of diseases requiring ventilation and/or drainage is also described.
