Non-invasive hemostatic closure devices: "patches and pads".

Initial device technologies developed to obtain hemostasis of percutaneous arteriotomy sites have used sutures or hemostatic plugs.

The purpose of this article is to review recent innovations using simple, but effective, hemostatic aids. Copyright 2003 Elsevier Inc. All rights reserved.
