RATCATH™ Rat Catheters


AVA Biomedical has a unique line of rat catheters designed to address issues associated with long-term catheterization.  All of our catheters are manufactured with the same thermoplastic polyurethane material as human catheters so you have continuity of materials between species. 


The RatCath Taper™  tapered  radio-opaque polyurethane catheters utilize a smooth tapered design to allow for small flexible catheter tips and thicker wall more manageable tubing at the exit site.  


The RatCath Taper™ features rounded tips to allows for vessel friendly insertion and the proximal end of the catheter has maximum wall thickness to decrease the likelihood of kinking.  This thicker wall proximal end allows for easier connection to ports, stub adaptors and tethers.
