摘要： Catheter for delivery of a medical device such as a stent or filter includes an inner tubular member and an outer tubular member movable relative to the inner tubular member. The outer tubular member is disposed at the distal end of the inner tubular member. The inner tubular member includes a fluid lumen defined therein, the fluid lumen having a fluid flow port directed to the exterior surface of the inner tubular member, A pressure chamber is defined by the inner tubular member, the outer tubular member, a proximal seal and a distal seal, and is in fluid communication with the fluid flow port, wherein fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to move the outer tubular member in a proximal direction allowing the medical device constrained by the outer tubular member to be released.

摘要： Catheter including an inner tubular member having a fluid lumen defined therein and an exterior surface. The exterior surface defining a first distal flow port and a second distal flow port. An outer tubular member is movable relative to the inner tubular member in a proximal direction and having an interior surface. A first pressure chamber is defined between the exterior surface and the interior surface, and between a first distal seal assembly and a first proximal seal assembly. A second pressure chamber is defined between the exterior surface and the interior surface, and between a second distal seal assembly and a second proximal seal assembly. Fluid introduced through the fluid lumen pressurizes the first pressure chamber and the second pressure chamber to generate a respective force at the first proximal seal assembly and to the second proximal seal assembly to urge the outer tubular member in the proximal direction.
摘要翻译：导管包括具有限定在其中的流体腔的内部管状构件和外部表面。所述外表面限定第一远端流动端口和第二远端流动端口。外部管状构件可以在近端方向上相对于内部管状构件移动并且具有内部表面。第一压力室被限定在外表面和内表面之间以及在第一远端密封组件和第一近端密封组件之间。第二压力室限定在外表面和内表面之间以及在第二远端密封组件和第二近端密封组件之间。通过流体腔引入的流体对第一压力室和第二压力室加压，以在第一近侧密封组件和第二近端密封组件处产生相应的力，以沿近侧方向推动外部管状构件。
