Rodent Cathethers and Cannulaes

Instech’s rodent catheters are designed and manufactured in collaboration with ReCathCo, a leading supplier of catheters for laboratory animal research.​

Instech and ReCathCo developed these catheters around three principles: first, that each model should be designed for the indi-cated species and vessel; second, that the catheter should have an ideal fit with the external device to which it will be attached; and, third, that customization should be sim-ple enough that every researcher can afford to have the insertion lengths and features that match his or her surgical techniques.

These catheters are made of medical-grade tubing, assembled and packaged in a clean-room and sterilized by ethylene-oxide gas. 


 

  1. Rounded tips reduce trauma to vessel lining, which can improve patency compared to cut tubing.
  2. Collars, or suture beads, near the distal tip hold the catheter in place in the vessel. Proper tip placement is critical for long-term patency.
  3. Perfusion holes are an option when the standard opening is likely to become obstructed.
  4. Spool collars are often used to hold the catheter in place where it exits the skin.

 

Two-piece catheters join small anatomy to practical connectors. The distal end can be as small as 1Fr (0.35mm) for mouse vessels or even 32ga (0.25mm) for intrathecal catheterization, while the proximal end fits 22ga or 25ga connectors.
