Apparatus and method to stop bleeding
A hemostatic device is provided to stop bleeding at a puncture site on an artery 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 compression member 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 compression member and a second balloon provided on the inner peripheral side in the second half of the curved compression member. The bleeding from a first artery is stopped by compressing the first artery at the puncture site using inflation of the first balloon and blood flow in the first artery is increased by compression of a second artery using inflation of the second balloon.

Pulmonary artery banding device
Pulmonary artery banding device includes an inflating handing ring, to be installed around the patient's pulmonary artery, an extending tube, and an insufflating button, the extending tube connecting insufflating button to the banding inflating ring, the banding ring being configured as a C-shape hydraulic sleeve forming a support for an inflating balloon, whose external wall is formed by a thin rigid silicon layer, and whose inside wall is formed by a thin flexible silicon layer, at the apart ends of the banding ring two brims being disposed to facilitate the size banding adjustment according with the pulmonary artery caliber. The banding ring is provided with holes for passage of sutures fixating the ring on the pulmonary artery of the patient; the insufflating button being configured as a cylindrical reservoir and being provided with holes for sutures. Also a method of using the banding ring for performing a medical procedure on a patient who is an infant or neonate.

COMPRESSION BALLOON WITH A RIGID FOOT FOR HEMOSTASIS
This device is a combination of an expandable or inflatable bladder or balloon in conjunction with a rigid or semi-rigid skin contact surface or structure to reduce bleeding from a skin insertion wound site and a vascular wound site after a vascular intervention or surgical procedure is performed. The device may be held in contact or close contact with the skin by a circumferential band, a clamp or other mechanism and provides a more consistent and uniform surface area contact and compression force. The contact surface or foot provides a uniform surface area contact as compared to the ever-changing contact surface area from an inflatable bladder.

TOURNIQUET ASSEMBLIES AND SYSTEMS, AND METHODS FOR CONTROLLING TOURNIQUETS
A tourniquet for occluding blood flow to a limb is improved by the addition of proximal and distal strain gauges. The proximal strain gauge may be monitored under conditions of total blood flow occlusion for time-varying signals indicative of volumetric limb changes arising from the subject's blood flow in the proximal section of the limb. Upon a change in limb occlusion pressure, the signals from the proximal strain gauge can be observed to change also, and the working pressure in the tourniquet can be adjusted safely in response. Automated control systems may further use inputs from a distal strain gauge and/or from a sensor that detects induced pressure changes within the tourniquet to improve the control of the tourniquet working pressure during operation to avoid unwanted blood flow past the tourniquet.
Radial artery sheath assembly
A radial artery sheath assembly includes a cuff that is wearable around a patient's wrist and a receiver is integrated into the cuff. The cuff is inflatable to compress an incision in the patient's wrist to achieve homeostasis for stopping bleeding. A ring is removably attachable to the cuff and a radial sheath is extendable through the ring to retain the radial sheath in the incision in the user's wrist when the ring is attached to the cuff. The ring is inflatable for compressing the radial sheath in the ring to inhibit the radial sheath from being removed from the incision. A lock is coupled to the ring and the lock releasably engages the receiver in the cuff for attaching the ring to the cuff.

HEMOSTATIC DEVICE
A hemostatic device is disclosed that includes: a pressing member configured to compress a patient's first puncture site; a first band body configured to be connectable to the pressing member; a second band body configured to be connectable to the pressing member; and a third band body configured to be connectable to the pressing member. The first band body has a first one end portion connected to the pressing member and having a first rotation axis and a free first other end portion. The second band body has a second one end portion connected to the pressing member and having a second rotation axis and a free second other end portion. The first band body and the second band body are configured to be rotatable about the first rotation axis and the second rotation axis so as to rotate toward or rotate away from the third band body.
