Infiniti’s Vet Stent-Cava is the key component in the minimally invasive treatment of intrahepatic portosystemic shunts. The stent was designed explicitly for this purpose and is laser cut from a nitinol tube. It features a closed cell design that is optimized to facilitate passing catheters from the caval side while trapping coils on the shunt side.


The Vet Stent-Cava is available in diameters from 14mm to 26mm as well as in custom configurations.

If you are uncertain about the size to choose, Infiniti’s telemedicine consult service can review images and assist with the planning of the procedure and post procedure management.


The percutaneous attentuation of intrahepatic portosystemic shunts requires a variety of devices in addition to the Vet Stent-Cava

Embo Coils™ are stainless steel embolization coils intended to be used in conjunction with the Vet Stent Cava and other Infiniti Medical catheters and accessories in the treatment of portosystemic shunts. The coils are designed to be compatible with Infiniti Medical catheters, guide wires and the Vet Stent-Cava™.

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

A 5 Fr catheter with metallic markers spaced 1 cm apart. is used to perform the angiogram for sizing of the caudal vena cava and stent selection. Selective catheters (Cobra and Berenstein configurations) are used to place coils into the shunt vessel.

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 Medical’s guide wires, the dilator is used to serially dilate the femoral artery in cases where the placement of large sheaths is required.

This radiopaque tape with calibrated markers is useful in both calibrating x-ray systems to measure vessels and in guiding stent placement.
