METHOD AND APPARATUS FOR PROMOTING HEMOSTASIS OF A BLOOD VESSEL PUNCTURE

摘要

An apparatus for promoting hemostasis of a puncture formed in a blood vessel accessible through an incision tract. The apparatus includes a distal balloon having a contracted position and an expanded position. The apparatus also includes a proximal balloon spaced by a predetermined initial distance from the distal balloon and having a contracted position and an expanded position. The apparatus further includes at least one catheter coupling the distal and proximal balloons to a source of pressurized fluid to selectively actuate the distal and proximal balloons between the contracted and expanded positions. And, the apparatus includes at least one rigid positioner associated with the at least one catheter to facilitate movement of the distal and proximal balloons proximally through the incision tract. The catheter has a flexible wall portion extending proximally of the distal and proximal balloons to facilitate everting of the distal and proximal balloons as the catheter is proximally withdrawn from the incision tract.
