Vascular Access Buttons™ and Harnesses™ are built around miniature externalized ports that simply and cleanly connect an implanted catheter to a syringe for direct access or to a tether for continuous access. Buttons are implanted subcutaneously and offer great long-term patency and the option of group housing. Harnesses can be installed after surgery but must be checked frequently so that they do not become too tight or loose.
Legacy tethers, including head block tethers for microdialysis, connect the animal to a fluid swivel, but catheters or tubing must be threaded up through the protective spring by the researcher.
Excellent patency and the ability to group house. Available in up to four channels for rats, and two channels for mice.
