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.
Claims14
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 surrounding the pusher, the lock nut 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;
- wherein the pusher includes first and second tabs extending radially from a body of the pusher, the first and second tabs of the pusher are positioned in first and second slots in the hub body, respectively;
- and
- a holder including first and second tabs extending radially from a body of the holder, wherein the first and second tabs of the holder are positioned in the first and second slots in the hub body, respectively.
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:
- an elastomeric seal proximal of and spaced apart from the compressible seal;
- a lock nut threadably engaged with the hub body such that rotation of the lock nut moves the compressible seal between an opening position and a closed position;
- a pusher engaged with the lock nut, such that rotation of the lock nut causes the pusher to axially move toward and/or away from the compressible seal;
- wherein the pusher includes first and second tabs extending radially from a body of the pusher, the first and second tabs of the pusher are positioned in first and second slots in the hub body, respectively;
- wherein an internal rim of the lock nut engages the first and second tabs;
- and
- a holder including first and second tabs extending radially from a body of the holder, wherein the first and second tabs of the holder are positioned in the first and second slots in the hub body, respectively.
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 having a distal surface juxtaposed with a proximal surface of the compressible seal;
- and
- a holder coupled to the valve hub;
- wherein a distal end region of the pusher extends into the hub body and is slidably movable relative thereto;
- and
- wherein a proximal end region of the pusher extends into the holder and is slidably movable relative thereto;
- wherein the pusher includes first and second tabs extending radially from a body of the pusher, the first and second tabs of the pusher are positioned in first and second slots in the hub body, respectively, and the first and second tabs of the pusher are axially movable in the first and second slots, respectively.
