The single microinfusion cannula consists of a guide cannula, cannula cap, injection inner tube, locking nut, and compatible tubing.
Medical-grade stainless steel is used as the fluid delivery pathway and implanted directly into tissue to ensure excellent biocompatibility. During long-term implantation, a steel wire inside the cannula cap prevents tissue from entering the base opening.

For drug administration or electrode insertion, the cannula cap can be removed directly. For ultra-low flow applications, drug delivery can be achieved via the injection inner tube.
To minimize tissue damage, different main cannula base diameters are designed according to animal body weight:

• Rodents: 400–650 μm

• Dogs / Monkeys: 650–800 μm
