Abstract
Systems and methods for applying targeted force to a radial access puncture site to provide hemostasis and close the puncture site. The system may include a cuff for placement over a wrist, a fluid source from which an inflation fluid may be delivered into an inflatable balloon associated with the cuff during use, and an inflatable balloon attached to the cuff. The balloon is disposed over the puncture site and inflated during use. The system may include one or more features configured to focus or target the applied force to the puncture site. For example, the balloon may include varying wall thickness, with a thinner-walled portion that applies a focused pressure to the puncture site, two balloons where one applies focused force, or an outer sheath with a hole placed over the balloon so that a portion of the balloon protrudes through the hole and applies focused force.
