Abstract
Devices, systems and methods for applying a bioadhesive substance to an internal surface of the eye, such as the retina, can include an outer sleeve having a proximal end, a distal end, a passageway extending along a length of the elongate body and an opening at the distal end of the elongate body, an applicator tip including an elongate body having a proximal end and a distal end, an applicator portion coupled with the distal end of the elongate body, and a substance supply lumen extending along a length of the device through which a bioadhesive substance can pass so that the bioadhesive substance can be applied to at least the applicator portion of the applicator tip. Some embodiments of the device can also have a source of the bioadhesive substance in fluid communication with at least the substance supply lumen.
