Canine Duct Occluder (ACDO)

The 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 as listed in the Sizes tab. The device should be 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 and can be accomplished only by arteriography.

* Device size refers to the waist of device as illustrated in Figure 1.
** Please note that a guiding catheter is sized by the outer diameter (OD) whereas a sheath is sized by the inner diameter (ID). This terminology accounts for the apparent difference in sizes between the guiding catheter and sheath required for a given size device.

Vascular Sheaths Vascular Sheath
This is a short sheath that is placed in the femoral artery to allow atraumatic and easy passage of catheters and other devices.
Marker Marker Catheter
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 aortogram for sizing of the ductus to allow for device selection and helps to overcome errors due to magnification.
Guide wires test (2) Guide Wire
Weasel Wire® and Rosen Wire are ideally suited to the unique requirements of this procedure. 
Sterile Pack (2) Sterile Pack
This pack contains all the equipment needed for an endovascular procedure including patient drapes, sterile gowns, syringes, and many other helpful accessories.
Dilators (1) Dilator
Constructed of polyurethane and tapered to Infiniti Medical’s guide wires, the dilator is used to serially dilate the femoral artery in cases where the placement of large sheaths is required.
