SoloPort catheters are also available coated with CBAS heparin coating for optimal hemocompatibility. The plastic port is designed specifically for rodent access. See the Catheter Page for complete information on catheters. There is little concern about the animal disturbing the port thereby obviating the need for a jacket or other protective apparatus. Because there is no chronic exit site wound, infection risks associated with ports are considerably lower than with external catheters.
Ports also allow for common housing.
The use of ports has provided many new research opportunities, and it represents a refined technique which has reduced animal use and minimized stress. The port was originally intended for intermittent bolus infusions and periodic sampling and access, but it is now widely used in protracted and continuous infusions.
