    摘要： The present invention generally relates to a medical device and procedure for accurately positioning a catheter across a desired region within a patient's vasculature. In particular, the present invention provides a hub assembly unit that allows a physician to precisely position a stent within a vessel utilizing a stent delivery catheter. The hub assembly unit includes a fine adjustment mechanism. The fine adjustment mechanism extends or contracts the length of the hub assembly unit in controlled incremental units. These controlled fine displacements are then translated directly to the stent delivery or balloon dilation catheter.

    摘要： A vascular introducer sheath including a tubular shaft and a hemostasis valve assembly connected to the proximal end thereof. The hemostasis valve assembly includes a hub, a cap and a normally-flat gasket disposed therebetween. Both the hub and the cap include continuous curved contact surfaces facing the top and bottom surfaces of the gasket. The continuous contact surfaces may be flat or gently curved and may be smooth or include a means to grip the gasket. At least one of the contact surfaces is formed at an angle to cause the gasket to become convex or concave in response to compression between the hub and the cap. The continuous contact surfaces uniformly distribute forces onto the perimeter of the gasket to avoid stress concentration points that may compromise gasket integrity. In addition, the continuous contact surfaces reduce the amount of pressure necessary to impart the curved shape of the gasket.

    摘要： Disclosed is a manifold including a housing having multiple ports and multiple bores networking the ports. An actuatable valve, such as a slidable valve, including one or more bores may be positioned in the housing such that the valve is actuatable between a first position and a second position. Actuation of the valve may selectively establish a desired fluid pathway through the manifold. One or more seals may be interposed between the valve and the housing. The seal includes at least a first sealing element, a second sealing element, and a land extending between the sealing elements. The sealing elements are configured to provide a fluid tight seal between the housing and the valve when the valve is in either the first or second position, and the land is configured to provide a fluid tight seal between the housing and the valve when the valve is in an intermediate position.
