Abstract
A method for closing a subcutaneous arterial wound is provided which utilizes a patient's whole blood by homogenously exposing the patient's whole blood to a porous matrix to initiate the clotting cascade of the patient's whole blood and situating the patient's whole blood at a position proximate to the arterial wound as the patient's whole blood is clotting. The method may include holding a subcutaneous mass comprising the patient's whole blood in position proximate the arterial wound as the patient's whole blood continues to clot, whereby a hemostatic closure comprising the patient's whole blood is formed.
Claims20
An apparatus for using a volume of a patient's whole blood to close a subcutaneous arterial wound in the patient, comprising:
- a syringe;
- a valve coupled to the syringe;
- a pulsatile indicator;
- a tube having a proximal end and a distal end;
- a porous matrix;
- and
- a cylindrical enclosure coupled to the tube and at least partially surrounding the porous matrix and configured to, in cooperation with the tube, effect homogenous exposure of the patient's whole blood to the porous matrix to initiate a clotting cascade in the patient's whole blood;
- wherein the tube and porous matrix are further configured to situate the patient's whole blood at a position proximate the arterial wound as the patient's whole blood is clotting in order to form a hemostatic closure comprising the patient's whole blood.
An arterial wound closure apparatus comprising:
- a syringe;
- a valve coupled to the syringe;
- a tube having a proximal end and a distal end;
- an introducer configured to receive the tube;
- a porous matrix;
- and
- an enclosure coupled to the tube and retaining the porous matrix and further configured to, in cooperation with the tube, effect homogenous exposure of a patient's whole blood to the porous matrix to initiate a clotting cascade in the patient's whole blood;
- wherein the tube, introducer and porous matrix are further configured to situate the patient's whole blood at a position proximate the subcutaneous arterial wound as the patient's whole blood is clotting in order to form a hemostatic closure comprising the patient's whole blood.
