<p>PURPOSE:To provide a baloon catheter for measurement of blood pressure, wherein a catheter withstands the force-back action by blood flow and a catheter does not cause the body kink after insertion into blood vessel. CONSTITUTION:A baloon catheter 20 of the disclosure is composed of a baloon 22 having the auxiliary activity for cardiac function in aorta by expanding and contracting action, a catheter tube 24 through which a pressurized fluid can be introduced and discharged for the baloon action, a flexible inner tube 30 which is extending along longitudinal direction passing through a catheter tube 24 and a baloon end 22 where a tube 30 is connected to a blood liaison unit 23. At the other tip of a catheter tube 24, a connecter 26 is installed, where a gateway 28 for the pressurized fluid and a measurement unit 32 are devised. A metallic stylet 42 is passed through a flexible inner tube 30 from a unit 32 towards a blood liaison unit 23 after insertion of a catheter into blood vessel.</p> |
