US Patent 10058334 Method to stop bleeding

A method to stop bleeding at a puncture site of an artery on a patient's arm includes wrapping a flexible band of a hemostatic device around at least a portion of the patient's arm, wherein the hemostatic device also comprises a more rigid member that is more rigid than the flexible band, a balloon, and a visually identifiable marker. The method also involves wrapping the flexible band around at least the portion of the patient's arm while the balloon is in an uninflated state and while an introducer sheath is in place at the puncture site. The visually identifiable marker is used to position the balloon in overlying relation to the puncture site while viewing the puncture site through the balloon and through the more rigid member. Fluid is introduced into the balloon to inflate the balloon to apply a compression force against the puncture site.
