The Amplatz Canine Duct Occluder (ACDO) is a self-expanding device made from a Nitinol wire mesh and is used to close patent ductus arteriosus (PDA) in dogs. A distal flat disk on the pulmonary artery side of the ductal ostium provides secure positioning in the pulmonary artery. As the device is implanted, the proximal cupped disk expands to conform to the shape of the ductal ampulla. The waist of the device spans the pulmonic ostium of the ductus and the dense nitinol mesh occludes the communication.


The device is available in several waist diameters from 3mm to 14mm. It is sized relative to the true diameter of the pulmonic ostium of the ductus as measured by arteriography in a ratio between 1.5 and 2. Appropriate sizing is crucial to the success of the procedure.

Client Case

Echocardiogram and arteriography showing flow through patent ductus arteriosus followed by succesful treatment with an ACDO.


The safe and accurate implantation of the AMPLATZ® Canine Duct Occluder requires the use of the products listed below.

Vascular introducers are placed in access vessels to allow atraumatic and easy passage of catheters and other devices.

This 5 Fr catheter has a non selective pigtail type distal configuration with metallic markers spaced 1 cm apart. This is used to perform the arteriogram for sizing of the ductus and device selection.

Infinti offers a variety of guide wires ideally suited to the unique requirements of this procedure.

This pack contains all the equipment needed for an endovascular procedure including patient drapes, sterile gowns, syringes, and many other helpful accessories.

Constructed of polyurethane and tapered to Infiniti’s guide wires, the dilator is used to serially dilate the femoral artery in cases where the placement of large sheaths is required.
