    • A delivery system (10) for implanting a medical device (30) such as a venous valve into the vasculature of a patient. The delivery system includes a delivery catheter (11) having a device-containing portion (15) adjacent to the distal end (14) thereof, and an inner member (16) extending through the catheter and beyond the distal end thereof, to an atraumatic distal tip portion (17) forward of the catheter distal end. The inner member extends through the medical device in the device-containing region, includes a proximal portion (18) with sufficiently large diameter to prevent longitudinal movement of the device as the catheter is retracted during deployment, and centers the device upon release from the distal catheter end during deployment. The inner member is preferably radiolucent underlying the device for contrast with radiopaque markers (43) of the device. The inner member preferably includes a flat portion (35) extending from the device-containing portion to the proximal end (22) to form a passageway or lumen (21) with the delivery catheter to transmit hydrating fluid to a device such as a valve containing lyophilized tissue requiring hydration immediately prior to patient implantation.
    • 一种用于将诸如静脉瓣的医疗装置(30)植入患者脉管系统的输送系统(10)。 递送系统包括具有与其远端(14)相邻的装置容纳部分(15)的输送导管(11)和延伸穿过导管并超出其远端的内部构件(16)到无创伤 远端尖端部分(17)在导管远端的前方。 内部构件在包含装置的区域中延伸通过医疗装置,包括具有足够大直径的近端部分(18),以在导管在展开期间缩回时防止装置的纵向移动,并且使得装置在从远端 导管在部署期间结束。 内部构件优选地是设备下方的射线可透以与装置的不透射线标记(43)形成对比。 内部构件优选地包括从装置容纳部分延伸到近端(22)的平坦部分(35),以与输送导管形成通道或内腔(21),以将保湿流体传送到装置,例如包含 在患者植入之前立即需要水合的冻干组织。
