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) administering a dose of an anticoagulant to the patient during the catheterization procedure;
(b) applying an ulnar pressure on an ulnar artery at an ulnar pressure site by inflating at least a first bladder to compress the ulnar artery for a purpose of attaining patent hemostasis of the radial artery;
(c) applying a radial pressure on the radial artery by inflating at least a second bladder at the access site to stop bleeding at the access site;
(d) continuing to apply the radial pressure on the radial artery for a duration of time to attain patent hemostasis of the radial artery;
(e) continuing to apply the ulnar pressure simultaneously on the ulnar artery for the purpose of attaining patent hemostasis of the radial artery;
(f) testing patency of only the radial artery and not the ulnar artery;
(g) attaining patent hemostasis of the radial artery;
wherein step (a) precedes all other steps, and step (e) comprises compressing the ulnar artery for only a part of the duration of time.

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.
