An introducer sheath assembly comprises a tubular sheath member having a deflectable distal end portion and a sheath member lumen, a handle assembly including a steering mechanism for deflecting the distal end portion of the sheath member, and a hemostasis valve assembly. The hemostasis valve assembly includes a side port member configured to be connected to a fluid source for introducing fluid into the sheath member lumen. The side port member is axially rotatable relative to the handle assembly and the sheath member such that the side port member can remain rotationally fixed relative to the fluid source as the handle assembly and the sheath member are rotated relative to the fluid source. The side port member may also be made transparent to allow for easy visualization of air bubbles, and is also configured to allow for evacuation of any visualized air bubbles.

Handle having hub with rotating infusion sideport

Various embodiments concern an introducer sheath assembly comprising a tubular sheath member having a deflectable distal end portion and a sheath member lumen, and a handle assembly including a steering mechanism for deflecting the distal end portion of the sheath member. The distal end portion of the sheath member can deflect in different directions along a plane by selective tension in one of two pull wires. The selective tension can be caused by selective proximal or distal axial translation of a shuttle assembly relative to the tubular sheath member. The selective proximal or distal axial translation can be controlled by selective clockwise or counterclockwise rotation of a control knob.
