1. A sheath comprising:
a hub forming a chamber and comprising:
a side port in fluid communication with the chamber, and
an introducer bore with a seal to maintain hemostasis of the introducer sheath while allowing a medical instrument to be introduced through the introducer bore into the chamber; and
a shaft coupled to the hub at a proximal end, the shaft forming a lumen that is in fluid communication with the chamber of the hub, the shaft comprising:
a braided wire frame with an annealed distal portion preventing the braided wire frame from unraveling at a distal end during assembly, an annealed proximal portion, and a middle portion of the braided wire frame being unannealed between the anneal distal portion and the anneal proximal portion, the middle portion maintaining physical properties of spring temper wire;
a jacket encompassing the braided wire frame, and
a liner forming an inner wall, the liner encompassed by the braided wire frame.
