Abstract
A hemostatic plug for sealing wounds in blood vessels comprising a tubular or spring-like body capable of buckling or collapsing upon application of a threshold axial force and having a fretted distal end. A collapsed portion of the plug lodges into the tissue tract and thus acts as a foothold allowing the plug to maintain continuous pressure on the puncture site necessary for a quick effective closure of the wound. Furthermore, collapse of the plug minimizes the chance of arterial penetration.
Claims1
A method for sealing a punctured blood vessel having a puncture site comprising the steps of:
- inserting a hemostatic plug having proximal and distal ends comprising at least one collapsible portion between said proximal and distal ends capable of collapsing upon application of a threshold force;
- applying a force to the plug causing the collapsible portion to buckle;
- forcing the proximal end of the plug towards the distal end;
- and lodging the collapsed portion between the blood vessel and surrounding tissue so as to fix the plug against the blood vessel.
