Silicone is a preferred catheter material for two reasons: it is highly resistant to chemicals, and its pliability can reduce vessel trauma. Check out our entire line of pig catheters here.

  • Available with or without female luer
  • Designed to enhance patency
  • Listed lengths are 60cm with two suture beads
  • Custom lengths and suture bead placement available, contact us with questions

SAI lymph catheter has been designed to minimize clotting and increase catheter longevity. These items are not available for purchase online. Please use the Order Form to complete a purchase, or contact us for customizations.

Rounded Tip- Our most popular catheters are our rounded-tip catheters. Rounded tips reduce trauma during implant as well as during subsequent catheter manipulation leading to a longer lasting catheter with fewer patency issues. Not all rounded tips are formed in the same way see here for more details.

SAI offers a range of catheters and cannula for the collection of CSF and for the administration of compounds to the intrathecal space in mice, rats, canines, primates and sheep. Draw cerebrospinal fluid, or perform intrathecal infusion in the subarachnoid space with these reinforced catheters.

  • PTFE coated stylet slides smoothly out of catheter
  • Reinforced tubing junction minimizes kinking at exit point from intrathecal space
  • All catheters are supplied sterile (ETO exposed)
