1. A method of obtaining hemostasis of a radial artery of a patient after performing a catheterization procedure at an access site of the radial artery, comprising performing the following steps:
- (a) continuously applying a hemostatic pressure to the radial artery at the access site;
(b) continuously applying an ulnar pressure to an ulnar artery at an ulnar pressure site, wherein the ulnar pressure only partially compresses the ulnar artery;
(c) maintaining simultaneously the hemostatic pressure and the ulnar pressure at least until hemostasis of the radial artery is achieved.

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.

14. A method of catheterization of a radial artery of a patient, directed at minimizing occurrences of radial artery occlusion, comprising the steps of:
- (a) inserting a sheath into the radial artery at an access site;
(b) performing a catheterization procedure using the sheath to access the radial artery;
(c) continuously applying a first pressure to an ulnar artery at an ulnar pressure site, wherein the first pressure only partially compresses the ulnar artery;
(d) removing the sheath from the radial artery;
(e) continuously applying a second pressure to the radial artery at the access site and (f) maintaining simultaneously the first pressure and the second pressure at least until hemostasis of the radial artery is achieved. - View Dependent Claims (15, 16, 17)
