What is a procedure like?
Patients are typically under general anesthesia and are given blood thinner during a procedure utilizing an AngioVac Cannula and Circuit. The procedure can be performed either percutaneously 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 veins and/or internal jugular veins.
An extracorporeal bypass circuit is created outside the body 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 self-expanding nitinol funnel shaped, angled tip available in either 20 degrees or 180 degrees. When the nitinol tip is deployed using the sheath, the funnel enables venous flow, prevents clogging of the cannula, and facilitates the removal of undesirable intravascular material, such as fresh, soft thrombi, emboli, or vegetation from the venous system into the filter. The circuit reinfuses the filtered blood back into the body to minimize blood loss and without causing hemodynamic instability. Click here for important risk information.
How does this compare to other therapies, like anticoagulants, catheter directed thrombolysis, mechanical thrombectomy, pharmacomechanical thrombectomy or open surgery?
The AngioVac Cannula and Circuit System offers an alternative to existing therapies that treat venous thromboembolism. While there are minimally invasive therapies available, the AngioVac System facilitates the en bloc removal of fresh, soft thrombi or emboli. The AngioVac System can be utilized in a wide range of areas from the neck to the groin and expands the treatment options available for patients.
Actual Procedure Results1
How common is this procedure?
The AngioVac System has been used for procedures in a growing number of hospitals nationwide since 2013.2 The AngioVac Cannula and Circuit are indicated for use during extracorporeal bypass for up to six hours. In addition, the AngioVac Cannula is indicated for the removal of fresh, soft thrombi and emboli. Please consult with your AngioDynamics representative for country-specific availability.
Will this work for me?
If you have a specific health concern, it is very important that you be an informed and active participant in your care. Whether the AngioVac System is appropriate for you is something which must be determined in consultation with your physician.
