Delivery catheter having a proximal SOLVED] and distal (21) and (20) end, and is suitable for deploying self-expanding, hollow tubular member (9), self-expanding tubular member (9) ( provided with a 10), of a medical device for delivering a therapeutic fluid to a body vessel. The present invention also relates to an organ perfusion method. By configuring so as to form a central part which is surrounded both sides by an annular ridge of the two by extending radially (11), [MEANS FOR SOLVING PROBLEMS] The tubular member (9), the vessel and through the vascular I produce in situ, the annular lumen therapeutic fluid can be applied in the local of passage that can maintain the flow of blood was. Minimally invasive and this particular device is suitable for repeatable organ perfusion. [Selection] Figure Figure 1【課題】遠位(21)および近位(20)端部を有し、自己拡張性、中空管状部材(9)、および自己拡張性管状部材(9)を配備するのに適した送達カテーテル(10)を備えた、体内脈管へ治療用流体を送達するための医療デバイスの提供。また本発明は、器官灌流方法にも関する。【解決手段】前記管状部材(9)を、放射状に拡張して2つの環状隆起部によって両側面を包囲された中央部(11)を形成するように構成することにより、脈管および脈管を通じた血液の流れを維持できる通路の局所で治療用流体が適用可能な環状管腔をin situで生み出す。このデバイスは、特に最小侵襲性および反復可能な器官灌流に適している。【選択図】図1
