Rat Catheters

Our tapered catheters combine features to give you “the best of both worlds” performance. They are thick-walled and heavy-duty where they exit the animal and soft and compliant in the vessel. Our catheters are available with rounded tips to decrease intravascular trauma. Rounded tips have been shown to increase patency, reduce histologic findings and offer less resistance while being inserted into the vessel.

大鼠鞘内导管(Rat Intrathecal Catheters)


Our Intrathecal Catheters are designed for implantation from the cisterna magna to the lumbar region. A reinforced tubing junction minimizes kinking at the exit point from the intrathecal space. A PTFE-coated stylet slides smoothly out of the catheter once in place. All catheters are ETO exposed.

Catheters for Intrathecal delivery or sampling in rodents. SAI offers a range of catheters and cannula for the collection of CSF or the administration of compounds to the intrathecal space in mice and rats. Our brand new Cisterna Magna cannula is made with non-reactive PEEK (instead of stainless steel) and utilizes a unique non-coring tip to guard against unnecessary trauma. Sample volumes of 50ul are easily collected and are repeatable for periods up to 12 weeks. For studies that require access to the CNS, look to SAI for the solution.

大鼠淋巴收集管(LYMT - Lymph Collection Catheters)


Lymph collection has long been considered a very difficult model for laboratory research. SAI has developed a new collection catheter for lymph that utilizes a unique catheter design. Lymph has the same clotting tendencies as blood. Coupled with its ultra-low production rate, catheter occlusion becomes a major limiting factor. SAI’s new innovation allows a micro infusion of a low concentration heparin solution to accompany the lymph collection, great reducing or eliminating this limitation.

Lymph Collection Tip: To prevent occlusionand optimize lymph collection, infuse a slow concentration heparin solution at a very low rate and keep your catheters open. Contact our Research Scientists on staff for details.
