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 partially surrounding the pusher. The lock nut is threadably engaged with the pusher such that rotation of the lock nut moves the pusher axially toward and/or away from the compressible seal.
Claims20
An introducer sheath, comprising:
- a valve hub defining a main port and a side port;
- and
- an elongate shaft extending from the valve hub;
- wherein 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 partially surrounding the pusher, the lock nut threadably engaged with the pusher such that rotation of the lock nut moves the pusher axially toward and/or away from the compressible seal.
An introducer sheath, comprising:
- a valve hub defining a main port and a side port;
- and
- an elongate shaft extending from the valve hub;
- wherein the main port includes:
- a hub body defining an enclosure with one or more windows formed therein;
- a compressible seal disposed within the hub body;
- an elastomeric seal proximal of and spaced apart from the compressible seal;
- and
- a lock nut disposed within the enclosure and exposed through the one or more windows for accessing the lock nut, the lock nut being rotatable relative to the hub body such that rotation of the lock nut moves the compressible seal between an opening position and a closed position.
An introducer sheath, comprising:
- a valve hub defining a main port and a side port;
- and
- an elongate shaft extending from the valve hub;
- wherein the main port includes:
- a hub body defining an enclosure;
- a compressible seal disposed within the hub body;
- a pusher having a distal surface juxtaposed with a proximal surface of the compressible seal;
- and
- a lock nut disposed within the enclosure of the hub body;
- wherein a distal end region of the pusher extends into the hub body and is slidably movable relative thereto;
- and
- wherein rotation of the lock nut moves the pusher axially toward and/or away from the compressible seal.
