The New and Improved Therapeutic Option for Dogs & Cats to Bypass Ureteral Obstructions

Since the SUB™ system was first introduced in 2009, we have consistently strived to provide the best possible solution for cats and dogs worldwide. Redesigned to reduce some of the most common complications seen in prior SUB™ devices, the SUB™ 3.0 consists of one or two locking loop pigtail catheters placed in the kidney(s), one straight catheter placed in the bladder, a subcutaneous titanium SwirlPort™, and a “Y” or “X” Connector junction for securing the catheters.

The SUB™ is packaged as a sterile kit with surgical suggestions and instructions for use. A complete surgical video and SUB™ nephrostomy placement video that compliments the printed instruction guide are available on YouTube:
