摘要:
A method for passivating a biomaterial surface includes modifying proteinaceous material disposed at the biomaterial surface. The passivation may be effectuated by exposing the biomaterial surface to therapeutic electrical energy in the presence of blood or plasma.

摘要:
The invention provides a combination comprising thrombin, fibrinogen, and lipidated tissue factor, as well as sealant compositions comprising thereof, and their use as a sealant agent as well as in the treatment of hemorrhages. The combination and compositions of the invention shows improved hemostatic properties and, at the same time, the quality of the clot formed is so consistent that the sealant efficiency is improved over those sealant compositions of the prior art.

摘要:
The invention relates to a device for the removal of foreign objects and thrombi from body cavities and blood vessels (12) using at least one guide wire (6, 7) provided with a distal element (2), said distal element (2) being provided with fibers (3) projecting radially outward and the device being provided with a cage (1) or tubular structure (16) which is suitable to be flatly collapsible under the external strain exerted by a micro-catheter (13) and transported inside the micro-catheter (13) and unfolds to its full cage (1) or tubular (16) structure when said external strain caused by the micro-catheter (13) is omitted, with said distal element (2) and the cage (1) or tubular (16) structure being designed so as to be longitudinally movable in relation to each other and the cage (1) or tubular structure (16) having an opening at the distal end through which the distal element (2) can be introduced into said cage (1) or tubular (16) structure. With the help of the inventive device thrombi (5) can be safely eliminated from blood vessels (12) in a simple manner.
摘要:
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.
摘要:
Surfaces of polymeric materials are coated with a layer of thermally denatured fibrinogen. The fibrinogen may be treated with thrombin to produce fibrin, and additional fibrinogen and factor XIII added to produce a cross-linked fibrin coating. The resulting coated surface is stable, anti-thrombotic and resistant to platelet adhesion. Polymeric materials coated in this way are useful in constructing vascular grafts and prosthetic devices, and provide test systems useful in the study of thrombogenesis.
