    • 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.

    • Medical device delivery systems and associated methods are provided. Delivery systems according to the invention include an elongated tubular member and a body member, such as a dilator, disposed therein. An intraluminal medical device is disposed on the dilator and within the tubular member prior to deployment. The delivery system includes a means for separating two or more portions of the distal end of the tubular member that aids in deploying the intraluminal medical device from the delivery system by separating two or more portions of the tubular member from each other to facilitate release of the intraluminal medical device from the body member. Various structures can be used for means for separating, including a cutting ring, activateable material on the tubular member, or other suitable structure. The provided devices and methods reduce friction occuring from relative movement between the sheath and dilator during deployment.
    • 提供医疗器械输送系统及相关方法。 根据本发明的递送系统包括细长管状构件和布置在其中的诸如扩张器的主体构件。 在展开之前,将管腔内医疗装置设置在扩张器上并在管状构件内。 递送系统包括用于分离管状构件的远端的两个或更多个部分的装置,其通过将管状构件的两个或更多个部分彼此分离来有助于将管腔内医疗装置从输送系统展开以便于释放 管腔内医疗器械从身体成员。 各种结构可以用于分离的装置,包括切割环,管状构件上的可激活材料或其他合适的结构。 所提供的装置和方法减少在展开期间由护套和扩张器之间的相对运动发生的摩擦力。
