Abstract
A glaucoma drainage device has a housing with an open outlet end. A tube is in fluid communication with the housing. An actuator is located in the housing. An actuation arm is located at least partially in the housing and is coupled to the actuator. A tapered arm is rigidly coupled to the actuation arm. A needle head is located opposite the tapered arm. A tapered end of the tapered arm is located at least partially in the tube. When the tapered arm is moved, it can clear an obstruction from the tube. When the needle head is moved, it can disperse aqueous or clear fibers from the drainage location.
