1. An introducer for insertion of a medical device into a patient's vasculature, the introducer comprising:
an elongate introducer body having a longitudinal axis, a proximal region, a distal region, and an inner lumen;
a hub coupled to the proximal region of the introducer body;
a hemostatic valve disposed within the hub and forming a liquid-tight seal across the inner lumen,
wherein the hub and the hemostatic valve are configured to part together,
wherein the hemostatic valve includes a proximal surface and a distal surface and a sloped region that is disposed in the proximal surface and is angled relative to a plane perpendicular to the longitudinal axis of the introducer body, wherein the sloped surface is configured to direct an object toward a central region of the hemostatic valve,
wherein the hemostatic valve includes a central void disposed between the distal surface and the proximal surface that reduces a stiffness of the central region of the hemostatic valve,
wherein the central void is enclosed by material of the hemostatic valve.
