The GTI (Groove Tipped Injection) Cannula® is designed as to treat depressed cutaneous scars without needing to use a sharp needle. It’s has a grooved tip that allows it to pass through the tissue smoothly, only severing the scar or higher density tissue, reducing the risk of damage to important nerves or vessels.
This makes it safer than regular subscision methods that use a sharp needle. A side port then allows for the injection of filler into the cavity area to plump and fill out the depression. Any qualified practitioner can use the GTI cannula and it fits all regular filler syringes.
