Envigo offers several procedures to access catheterized vessels for injection or sample withdrawal in the mouse and rat models. While each method of catheter access and closure offers unique advantages, our standard catheterization closure is the subcutaneous pouch with fixed exteriorization.

Other exteriorizations include, but are not limited to, use of a harness, PinPort™, or Dacron mesh button. Envigo is also able to offer our catheterization models implanted with a Culex™ catheter, hydro-coated catheter, heparin-coated catheter, or silicone or polyethylene catheter. For complete descriptions of exteriorization options for catheterized rodents, please reference catheter exteriorization options.
