A Patient’s Guide to
Cannula and Circuit
PROCEDURE TERMINOLOGY
Cannula —a tube inserted into a vein
to either drain or return fluids from/to
the body
Centrifugal Pump—a pump used to
create suction for fluid removal
Percutaneous—a catheter is inserted
through the skin to allow for introduction
of the AngioVac Cannula into a vein
Open Surgery—the AngioVac Cannula
and Circuit can be used during open
surgery allowing the physician to view the
vein before and during the procedure
Procedure Overview
Getting Started
Patients are typically under general anesthesia
and are given blood thinner during a procedure
utilizing an AngioVac Cannula and Circuit.
Your physician can perform the procedure
percutaneous or open.
In either procedure there are two access
points required— an incision is made for the
AngioVac Cannula and an incision is made for
the Reinfusion Cannula. The access points may
include any combination of the femoral vein
(large vein that starts in the lower abdomen
and goes down into the thigh) and/or internal
jugular vein (located in the neck and drains
blood from the head, brain, face and directs it
toward the heart).

How It Works
An extracorporeal bypass circuit is created outside the body (shown above) consisting of an
outflow line, a centrifugal pump, a filter and an inflow line.
Once the AngioVac Cannula and the Reinfusion Cannula are inserted into the veins the centrifugal pump
is activated. This creates a one-way flow that provides suction at the tip of the AngioVac Cannula. The
AngioVac Cannula has a balloon activated tip. This unique tip enhances venous flow, prevents clogging
of the cannula and facilitates the removal of undesirable intravascular materials from the venous system
into the filter. At the same time, the circuit reinfuses the filtered blood back into the body to maintain
blood volume and keep the patient hemodynamically stable.
