Abstract:
1. A method of promoting hemostasis of a puncture in a blood vessel accessible through an introducer sheath inserted in an incision tract, the method comprising: positioning distal and proximal balloons in the incision tract by advancing the distal and proximal balloons through the introducer sheath until the distal balloon is disposed within the blood vessel and the proximal balloon is disposed outside of the blood vessel; inflating the distal and proximal balloons; pulling the distal and proximal balloons in a proximal direction until the distal balloon engages an inner wall of the blood vessel; everting the distal balloon until it is withdrawn from the blood vessel; holding the proximal balloon in place for a period of time sufficient to at least initiate formation of thrombus; everting the proximal balloon; and withdrawing the distal and proximal balloons from the incision tract.
