Ophthalmic injection device |
abstract |
A device for controlled delivery of an injection material to tissue spaces of an eye that are not normally open, such as the subconjunctival space, the suprachoroidal space and the subretinal space. The device comprises an elongated body with a hollow cannula at the distal end, a slidable plunger at the proximal end, and a reservoir for the material to be injected residing between the cannula and the plunger. The plunger is mechanically coupled to a source of force such as a spring or pressurized gas reservoir such that an injection force is applied to the injection material within the device prior to delivery of the injection material into an eye. A valve that is normally closed to prevent flow of the injection material during application of the injection force is placed in the flow path between the cannula and reservoir. Due to the injection force placed on the injection material, actuation of the valve allows controlled flow from the reservoir through the cannula and into the tissue space. |
