原文（中文）

Devices and methods for providing a hemostatic valve fluid seal within a guide catheter are disclosed. A delivery apparatus can include a handle including a proximal segment including one or more fluid seals mounted within the proximal segment, an intermediate segment disposed adjacent and distal to the proximal segment, the intermediate segment including an inner surface defining a first lumen having a first inner diameter, and a distal segment disposed adjacent and distal to the intermediate segment, a shaft extending distally from the handle, the shaft including a second lumen extending between a distal end and a proximal end of the shaft, the second lumen including a second inner diameter that is smaller than the first inner diameter of the first lumen, and a fluid seal that is a circular elastomeric silicone comprising two perpendicular cross-hair cuts at the center of the seal and extending partially through the seal.
