Abstract
An introducer for insertion of a medical device into a patient's vasculature includes an elongate introducer body, a hub, and a hemostatic valve. The elongate introducer body includes a longitudinal axis, a proximal region, a distal region, and an inner lumen. The hub is coupled to the proximal region of the introducer body. The hemostatic valve is disposed within the hub and forms a liquid-tight seal across the inner lumen. The introducer includes a guide configured to guide an object towards the center of the valve during insertion of the object.
Claims13
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;
- and
- a hemostatic valve disposed within the hub and forming a liquid-tight seal across the inner lumen,
- wherein the hemostatic valve is a unitary structure comprising a valve portion and a guide portion, the guide portion configured to direct an object toward a central region of the hemostatic valve,
- wherein a rigidity, toughness, or hardness of the guide portion is greater than a rigidity, toughness, or hardness of the valve portion,
- wherein the valve portion comprises a central void that reduces a stiffness of the central region of the hemostatic valve, wherein the central void is disposed between a distal surface and proximal surface of the valve portion, and
- wherein the central void is enclosed by material of the valve portion.
