“Willi”, our male catheterization trainer, is specifically designed to fit our catheterization stand as well as older style Laerdal Manikins and is made with soft, supple silicone rubber for a realistic feel. "Willi" includes a removable foreskin and prostate band to simulate an enlarged prostate. Our proprietary bladder system, which can be used with an IV bag or a pressure infuser bag, confirms successful catheterization with urine flashback.
