Abstract

An apparatus includes a body, an outer cannula, and an inner cannula slidably disposed in the outer cannula. The inner cannula includes an open proximal end, an open distal end configured to pierce a retina, and a lumen for delivering first and second fluids into a subretinal region of the eye. The apparatus also includes a first supply conduit configured to supply the first fluid to the lumen, and including a first distal conduit end fixedly secured relative to the inner cannula such that the first distal conduit end is configured to translate longitudinally together with the inner cannula. The apparatus also includes a second supply conduit configured to supply the second fluid to the lumen, and including a second distal conduit end fixedly secured relative to the inner cannula such that the second distal conduit end is configured to translate longitudinally together with the inner cannula.
