Radial Artery Closure Device

摘要

A radial closure device has a compression element to place compression force against the radial access site. The invention further comprises an occlusion element that places an occlusion force against the ulnar artery to reduce blood pressure at the arteriotomy site and increase blood flow in the radial artery thereby reducing radial artery occlusion and reducing the time and compression force to achieve hemostasis. A radial restriction element can also be placed upstream of the access site to further reduce radial blood pressure at the arteriotomy site.

主权项

1. A radial artery closure device for providing hemostasis to a radial artery access site, said closure device comprising;
A. a first support plate having a compression surface attached thereto, said compression surface being attached to a compression element that supplies a compressive force to said compression surface to compress the radial artery access site without totally occluding blood flow in the radial artery, said compressive surface providing hemostasis at the radial access site, B. A holding strap to hold said first support plate such that said compression surface is adjacent the radial artery access site, C. a second surface attached to a second support plate, said second surface being attached to a second element that supplies a second force to said second surface to at least partially occlude blood flow in a second artery other than the radial artery, the second artery being connected to the radial artery via collateral arteries downstream of the access site.
