For the best results, dog internist practicing in the field will find a dog double cavity balloon catheter useful. Fluid management problems may be those that require more than one cavity of a catheter or even balloon catheter. During some practices when fluids have to be drained while drugs are being injected, the concept of dual cavities comes into play. Our dual cavity differentiation allows therapies to be carried out in the event of critical conditions. By incorporating the latest techniques and materials, our catheter performs well, is safe, and meets the demands of all veterinary clinics.
