Method to stop bleeding, with short hemostasis duration using a low dose of anticoagulant
First Claim
1. A method of attaining patent hemostasis of a radial artery of a patient when performing a catheterization procedure at an access site of the radial artery, comprising performing the following steps:
- (a) applying an ulnar pressure on an ulnar artery at an ulnar pressure site by compressing the ulnar artery at least partially for a purpose of attaining patent hemostasis of the radial artery;
(b) applying a radial pressure on the radial artery at the access site to stop bleeding at the access site;
(c) continuing to apply the radial pressure on the radial artery for a duration of time to attain patent hemostasis of the radial artery;
(d) continuing to apply the ulnar pressure on the ulnar artery at the ulnar pressure site to compress the ulnar artery at least partially for a first period of time for the purpose of attaining patent hemostasis of the radial artery, wherein the first period of time is at least several minutes;
(e) attaining patent hemostasis of the radial artery;
wherein the ulnar pressure is not applied on the ulnar artery for a second period of time up until and including the moment in which patent hemostasis of the radial artery is attained.

Abstract
Disclosed are methods and devices for obtaining patent hemostasis of the radial artery by compressing the uninstrumented ulnar artery to increase radial artery flow. The device comprises a band having an inflatable bladder for applying blunt pressure to the ulnar artery. The method comprises applying a pressure to the homolateral ulnar artery and applying a pressure to the radial artery at the access site to obtain hemostasis at the access site. The method further comprises administering an anticoagulant to a patient at a dose ranging from about 20 units per kg of body weight to about 30 units per kg of body weight.
