Apparatus and method to stop bleeding
First Claim
1. A method directed at attaining hemostasis of a radial artery of a patient after performing a catheterization procedure at an access site of the radial artery, comprising performing the following steps:
- (a) applying a first pressure on an ulnar artery at an ulnar pressure site by inflating at least a first balloon for a purpose of reducing risk of post-instrumentation radial artery occlusion;
(b) applying a second pressure on the radial artery by inflating at least a second balloon at the access site to stop bleeding at the access site;
(c) continuing to apply the second pressure on the radial artery to attain hemostasis of the radial artery;
(d) continuing to apply the first pressure simultaneously on the ulnar artery for the purpose of reducing risk of post-instrumentation radial artery occlusion;
(e) reducing the first pressure on the ulnar artery to zero before attaining hemostasis of the radial artery, whereby the first pressure is not applied up until and including the moment in which hemostasis of the radial artery is attained;
(f) attaining hemostasis of the radial artery.

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.

12. A method directed at attaining hemostasis of a radial artery of a patient after performing a catheterization procedure at an access site of the radial artery, comprising the steps of:
-
(i) placing at least a first balloon on an ulnar artery at an ulnar pressure site; (ii) placing at least a second balloon at the access site on the radial artery where bleeding is to be stopped; (iii) applying a radial pressure on the radial artery at the access site by inflating at least the second balloon; (iv) applying an ulnar pressure on the ulnar artery at the ulnar pressure site by inflating at least the first balloon for a purpose of reducing risk of post-instrumentation radial artery occlusion; (v) continuing to apply the radial pressure on the radial artery at the access site for a duration of time to attain hemostasis of the radial artery; (vi) continuing to apply the ulnar pressure simultaneously on the ulnar artery at the ulnar pressure site for the purpose of reducing risk of post-instrumentation radial artery occlusion; (vii) attaining hemostasis of the radial artery, wherein step (iii) precedes step (iv) and the radial pressure is applied while a sheath or a catheter remains inserted in the radial artery or after the sheath or the catheter is removed from the radial artery; and
wherein step (vi) comprises reducing the ulnar pressure on the ulnar artery to zero before attaining hemostasis of the radial artery, whereby the ulnar pressure is not applied up until and including the moment in which hemostasis of the radial artery is attained. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method directed at attaining hemostasis of a radial artery after performing a catheterization procedure using a sheath at an access site of the radial artery on a wrist of a patient, comprising performing the following steps:
-
(a) applying a first pressure on an ulnar artery at an ulnar pressure site by inflating at least a first balloon to compress the ulnar artery while the sheath remains inserted in the radial artery for a purpose of reducing risk of post-instrumentation radial artery occlusion; (b) removing the sheath from the radial artery while maintaining the first pressure on the ulnar artery; (c) applying a second pressure on the radial artery by inflating at least a second balloon at the access site to stop bleeding at the access site; (d) continuing to apply the first pressure on the ulnar artery for the purpose of reducing risk of post-instrumentation radial artery occlusion; (e) continuing to apply the second pressure on the radial artery for a duration of time to attain hemostasis of the radial artery; (f) reducing the first pressure on the ulnar artery to zero before attaining hemostasis of the radial artery, whereby the first pressure is not applied up until and including the moment in which hemostasis of the radial artery is attained; (g) attaining hemostasis of the radial artery, wherein step (a) precedes step (c). - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
