Abstract
A method for hemostasis of an artery having a puncture after arterial catheterization, the catheterization using an introducer sheath, the method including the steps of inserting into an artery a catheter introducer having a forward end and a balloon adjacent the forward end prior to arterial catheterization, following arterial catheterization and removal of a catheter from the catheter introducer, retracting the catheter introducer such that the forward end thereof lies exterior of the artery adjacent a puncture in the wall of the artery, inflating the balloon, thereby causing inward collapse of the forward end of the catheter introducer, thereby defining an enhanced surface area surrounded by the balloon adjacent the puncture for hemostasis, and following hemostasis, deflating the balloon and removing the catheter introducer from the patient.An introducer sheath suitable for use in the method is also described and claimed.
