The precise pitch of the Dual Optofluid Cannula with interchangeable injectors guarantees an optimal bilateral implantation where both light and fluid injection can be used. The interchangeable configuration saves space and weight and can be used with multiple lengths of optical and fluid injector.

Each cannula ships with two plugs to prevent the guiding tubes from being clogged at implantation and between uses. Since both the optical and fluid injectors do not stay inside the brain for a long time, this cannula has the additional benefit of keeping them free of biological debris.

Depending on the pitch between the two optical fibers, two receptacle types are offered: small (S) and large (L). The model S is required when the pitch is equal to or smaller than 1.7 mm.  The minimum possible distance between the tubes is the guiding tube diameter. For pitch more than 1.7 mm, the model L is needed.
 

Notes:
• Optical Injector and Fluid Injectors for Dual Optofluid Cannulas must be ordered separately. Be careful to order the right amount of injectors.
• The tubing internal diameter must match the optical injector fiber core diameter (see tables in section GUIDING TUBE CODES).
• Polyethylene tube to connect a fluid delivery system is sold separately.
