Introducer assembly having a low-profile access sheath and a hub assembly

A hub assembly for an introducer assembly, comprising:

• a body defining an interior passageway, the body having a proximal end and a distal end;
• a valve assembly positioned within the interior passageway of the body, the valve assembly comprising,
• a valve collar positioned within the interior passageway of the body and defining an interior passageway;
• and
• a valve member connected to the valve collar, the valve member being at least partially movable from a first position to a second position with respect to the valve collar;
• and
• a vacuum chamber interconnected with the distal end of the valve collar and in fluid communication with the interior chamber of the body, the vacuum chamber including a vacuum port.

An introducer assembly, comprising:

• a multi-layer sheath comprising a proximal end, a distal end, and at least one lumen disposed therethrough, the multi-layer sheath having an inner layer having an outer diameter, an outer layer having an outer diameter, and at least one coil embedded between the inner layer and the outer layer;
• and
• a hub assembly interconnected with the proximal end of the multi-layer sheath and having a proximal end, a distal end, and a body defining an interior chamber in fluid communication with the lumen of the multi-layer sheath, the body having a proximal end and a distal end;
• a valve assembly positioned within the interior chamber of the body, the valve assembly comprising,
• a valve collar positioned within the interior chamber of the body and defining an interior passageway, the interior passageway being in fluid communication with the at least one lumen of the sheath;
• a valve member connected to the valve collar, the valve member being at least partially movable from a first position to a second position with respect to the valve collar;
• and
• a vacuum chamber positioned distal to the valve assembly and in fluid communication with the interior chamber of the body and the lumen of the sheath, the vacuum chamber including a vacuum port.
