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) applying hemostatic pressure to the radial artery at the access site;
(b) providing an increased flow of blood in the radial artery; and
(c) maintaining simultaneously the hemostatic pressure and the increased flow of blood in the radial artery at least until hemostasis of the radial artery is achieved;
wherein step (b) comprises continuously applying an ulnar pressure to an ulnar artery at an ulnar pressure site whereby the ulnar pressure only partially compresses the ulnar 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.
