Method of transradial catheterization, device for ulnar artery compression, and method of use

摘要

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.

主权项

1. 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) applying a first pressure to a homolateral ulnar artery at an ulnar pressure site while the sheath remains inserted in the radial artery, thereby increasing flow in the radial artery; (d) removing the sheath from the radial artery while maintaining the first pressure to the ulnar artery; and (e) applying a second pressure to the radial artery at the access site to obtain hemostasis at the access site, wherein step (c) precedes step (e).
