Method to stop bleeding, with short hemostasis duration using a low dose of anticoagulant
First Claim
1. A method to attain patent hemostasis of a radial artery during a catheterization procedure involving the radial artery that is punctured at an access site, comprising:
- (a) increasing a flow of blood in the radial artery;
(b) administering an anticoagulant, wherein a dosage of the anticoagulant is less than an equivalent of 50 units of unfractionated heparin per kg of body weight;
(c) applying hemostatic pressure to the access site; and
(d) attaining patent hemostasis of the radial artery.

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.

16. A method to attain patent hemostasis of a radial artery during a catheterization procedure involving the radial artery that is punctured at an access site, comprising:
-
(a) increasing a flow of blood in the radial artery; (b) administering an anticoagulant at a dosage that is less than an equivalent of 50 units of unfractionated heparin per kg of body weight, wherein the anticoagulant is selected from a group consisting of heparin, dalteparin, danaparoid, enoxaparin, unfractionated heparin, other low molecular weight heparin, direct thrombin inhibitors including hirudin, argatroban, bivalirudin and all substances derived from and/or related to the foregoing substances; (c) applying hemostatic pressure to the access site; and (d) attaining patent hemostasis of the radial artery. - View Dependent Claims (17, 18, 19)
