Cannula for subcutaneous implantation of pharmaceutical depots

Implantation cannula are specialized medical devices with a wide range of applications. This example is for patients with erythropoietic protoporphyria (EPP) whos’ skin experiences a phototoxic effect when exposed to sunlight. Also called, sun allergy, it can cause severe skin irritation.

The cannula provides a means to implant the rod-shaped pharmaceutical capsule under the skin. This implant slowly releases medication allowing the patient to spend longer periods of time in sunlight with less painful irritation. The procedure must be repeated at the end of each capsule’s effectiveness period.
