Abstract:
A hemostatic device is provided to stop bleeding at a puncture site on the wrist of a patient, the device comprising a transparent flexible band to be wrapped at the site where the bleeding is to be stopped, a curved frame having an inner peripheral side and possessing a first curved portion in its first half and a second curved portion in its second half, a first balloon provided on the inner peripheral side in the first half of the curved frame and a second balloon provided on the inner peripheral side in the second half of the curved frame. The bleeding from a first artery is stopped by compressing the first artery at the puncture site using inflation of the first balloon and the blood flow in the first artery is increased by compression of a second artery using inflation of the second balloon.

Claim (Index 1):
A method directed at obtaining hemostasis of a radial artery after performing a catheterization procedure on a wrist of a patient at an access site of the radial artery, comprising performing the following steps:\n (a) wrapping and securing a band around the wrist of the patient at the access site where bleeding is to be stopped, said band comprising a first balloon and a second balloon; (b) positioning the first balloon to provide a first compressive force on an ulnar artery, wherein the first balloon is located substantially in a palmar aspect of the band proximate to a base of a palm whereby the first compressive force is focal at a Guyon's canal, and wherein a width of the first balloon is less than 70% of the width of the band whereby inflation of the first balloon does not influence perfusion of the radial artery; (c) positioning the second balloon to provide a second compressive force on the radial artery at the access site that is about 2 cm from the base of the palm, wherein the band is configured to locate a substantial part of the second balloon distal from the base of the palm, whereby when the band is wrapped around the wrist positioning the first balloon to provide a focal compressive force at the Guyon's canal, the second balloon positions itself to cover the access site; (d) applying the first compressive force on the ulnar artery at the Guyon's canal by inflating the first balloon; (e) applying a second compressive force on the radial artery at the access site by inflating the second balloon; (f) continuing to apply the first compressive force to the ulnar artery at the Guyon's canal; (g) continuing to apply the second compressive force for a duration of time until at least hemostasis of the radial artery is obtained, wherein the first compressive force on the ulnar artery and the second compressive force on the radial artery are maintained simultaneously.
