Abstract
A method of closing an incision includes inserting a catheter (32) and the first and second balloons (50, 58) through an introducer (48) to have the first balloon (50) located in the artery (24). Next, the catheter (32) and the first balloon (50), which has been inflated, are withdrawn to apply a first force (F.sub.1) to the puncture hole (22) and close the puncture hole (22). The method is distinguished by injecting a clotting agent (60) into a second balloon (58) to inflate the second balloon (58) and to create a cavity between the insertion hole (68) and the puncture hole (22). The slit (62) in the second balloon (58) expands into an open position as a result of a pressure (P) within the second balloon (58) to eject the clotting agent (60) therefrom. Next, the first balloon (50) is deflated, and the catheter (32) and the first and second balloons (50, 58) are removed from the insertion hole (68). Finally, a second force (F.sub.2) is applied to the insertion hole (68) to stop the flow of blood.
