Abstract:
A method for hemostasis of an artery having a puncture after arterial catheterization, said catheterization using an introducer sheath, the method comprising the steps of:inserting into an artery a catheter introducer having a forward end and a balloon adjacent said forward end prior to arterial catheterization;following arterial catheterization and removal of a catheter from the catheter introducer, introducing an inflatable anchor into the artery via the catheter introducer;inflating the inflatable anchor inside the artery;retraction of the anchor, until it engages the forward end of said catheter introducer and further engages an inner wall surface of a wall of the artery, whereby the catheter introducer is also retracted such that the forward end thereof lies in the vicinity of the wall of the artery, whereby the anchor blocks blood flow from the artery at the catheter introducer and the balloon adjacent the forward end of the catheter introducer lies outside an outer surface of the wall of the artery;inflating the balloon adjacent the forward end of the catheter introducer sufficiently to cause the forward end of the catheter introducer to be withdrawn completely from the wall of the artery and simultaneously to prevent blood flow from the artery through the artery wall;deflating the inflatable anchor and withdrawal thereof from the artery; andfollowing hemostasis, deflating of the balloon adjacent the forward end of the catheter introducer and removal of the catheter introducer from the patient.
