Method of transradial catheterization, device for ulnar artery compression, and method of use
First Claim
1. A method of obtaining patent hemostasis of a radial artery of a patient after performing a catheterization procedure using a sheath to access the radial artery wherein the sheath is inserted into the radial artery at an access site, comprising performing the following steps in sequence:
- (i) applying hemostatic pressure to the radial artery while simultaneously increasing radial artery flow by applying an ulnar pressure to an ulnar artery at an ulnar pressure site;
(ii) maintaining continued partial compression of the ulnar artery, thereby maintaining an increased flow of blood inside the radial artery, 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.

15. 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 while simultaneously increasing radial artery flow by applying an ulnar pressure to an ulnar artery at an ulnar pressure site; (b) maintaining continued partial compression of the ulnar artery while achieving cessation of bleeding at the access site of the radial artery; (c) attaining hemostasis of the radial artery; and (d) removing pressure to the ulnar artery, wherein steps (a) and (b) precede step (c). - View Dependent Claims (16, 17, 18, 19)
