Abstract: Drug eluting vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. The devices and methods rely on a combination of the body's own natural mechanism to achieve hemostasis with chemical and/or biological agents to accelerate the hemostatic process. One method includes the steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A chemical and/or biological sealing member disposed proximal the expansible member is then displaced so as to expose a chemical and/or biological region or release region of the device. At least one chemical and/or biological agent is thereafter released from the device and into the tissue tract to accelerate the occlusion process in the tract.

Abstract: The present invention relates to therapeutic methods for preventing or reducing neurological events utilizing a glycosaminoglycan and a serpin, including complexes and conjugates thereof. Methods of the present invention may be advantageous for preventing or reducing neurological events prior to, or during medical or surgical procedures, and after a neurological event. In particular, the present invention deals with neurological events associated with the generation of emboli that can lodge in the brain and/or cerebral circulation during cardiac surgery.

Abstract: The present invention provides compositions and methods for the treatment of cardiovascular diseases. More particularly, the present invention relates to modifying thrombus formation by administering an agent which, inter alia, is capable of (1) inactivating fluid-phase thrombin and thrombin which is bound either to fibrin in a clot or to some other surface by catalyzing antithrombin; and (2) inhibiting thrombin generation by catalyzing factor Xa inactivation by antithrombin III (ATIII). The compositions and methods of the present invention are particularly useful for preventing thrombosis in the circuit of cardiac bypass apparatus and in patients undergoing renal dialysis, and for treating patients suffering from or at risk of suffering from thrombus-related cardiovascular conditions, such as unstable angina, acute myocardial infarction (heart attack), cerebrovascular accidents (stroke), pulmonary embolism, deep vein thrombosis, arterial thrombosis, etc.

Abstract: The present invention relates to compositions and methods for the treatment of diseases or conditions characterised by excess thrombin generation or activity. In particular, the invention provides combination compositions comprising low molecular weight heparin (LMWH) and low molecular weight dermatan sulphate (LMWDS). Such compositions are well suited for the treatment of said diseases or conditions, and they exert an effect which is greater than sum of the effects of LMWH and LMWDS if dosed as single agents, i.e. the combination composition exerts a synergistic effect.
