A slotted introducer cannula includes an introducer sheath insertable into a patient's tissue. The cannula has an open distal end and an open proximal end, and an inner lumen therethrough. The introducer cannula may include at least one aperture in a side wall thereof, which allows fluid communication between the inner lumen and the area outside the cannula. The introducer cannula may also be in communication with a vacuum source, which may remove fluid near the distal end of the introducer cannula.
