Patent number: 11439408Abstract: A hemostatic device includes a flexible band adapted to be wrapped around a patient's limb at a site on the limb where bleeding is to be stopped, a portion for securing the band in a wrapped state to the limb, a curved plate which is made of a material more rigid than the band and at least a portion of which is curved toward the inner peripheral side thereof, a main balloon which is provided on the inner peripheral side of the curved plate and which inflates when a fluid is introduced therein, and a pressing member which is provided between the curved plate and the main balloon so that at least a portion thereof overlaps with the balloon and which is adapted for pressing against the balloon. The device provides an excellent hemostatic effect and prevents numbness and poor circulation in areas peripheral to the site of attachment.Type: GrantFiled: February 21, 2020Date of Patent: September 13, 2022Assignee: TERUMO KABUSHIKI KAISHAInventors: Satoshi Wada, Shigeki Numata, Hiroshi Yagi

Patent number: 10058334Abstract: 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.Type: GrantFiled: April 13, 2018Date of Patent: August 28, 2018Assignee: TERUMO KABUSHIKI KAISHAInventors: Satoshi Wada, Shigeki Numata, Hiroshi Yagi
