The MILA Retropulsion™ Catheter is a Short-Term Canine Urinary Drainage Catheter for sampling and drainage of the bladder in male dogs. The catheter allows for comprehensive retrograde hydropulsion of lodged urethral calculi into the urinary bladder. If clinically required, the catheter allows for rapid easy exchange to a Long-Term Foley using an open ended silicone Foley and guidewire.
