Multiple Fluid Injections Cannulas
The Optical fiber Multiple Fluid Injection Cannula (OmFC) is used for light delivery and repeated drug or light-sensitive dye injections. Its continuous guiding tube path permits multiple insertions of a fluid injector pre-loaded with pharmacological agents, viruses, or plasmids. The user selects the cannula's optical fiber and guiding tube lengths to reach the targeted brain region. After the surgery and before fluid delivery, the fluid injector must be fully inserted into the cannula guiding tube. The liquid injector consists of a 1.25 mm ferrule and a corresponding sleeve connector. The cannula includes a plug for the guiding tube when the injector is not in place. The plug is 100 µm longer than the guiding tube protrusion to avoid clogging.Notes:
• A holder is available for implantation to secure the Multiple Fluid Injections Cannulas (SCH_OmFC).
• The Fluid Injector for the Multiple Fluid Injections Cannulas must be ordered separately (FI_OmFC).
• A 2-meter length of polyethylene tubing is sold separately to connect a fluid delivery system to the cannula (PT_OFC_2).
