Abstract
An introducer sheath including a valve hub and an elongate shaft extending from the valve hub. The valve hub defines a main port and a side port. The main port includes a hub body, a compressible seal disposed within the hub body, a pusher at least partially positioned within the hub body and slidably movable relative thereto, and a lock nut surrounding the pusher. The lock nut is threadably engaged with the hub body such that rotation of the lock nut moves the pusher axially toward and/or away from the compressible seal.
