US Patent:

20220346876, Nov 3, 2022

Filed:

Jul 15, 2022

Appl. No.:

17/866111

Inventors:

- Chicago IL, US
William R. Voss - Hinsdale IL, US

International Classification:

A61B 18/20
A61B 17/00

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.

William R. Voss - Hinsdale IL, US

International Classification:

A61B 17/00
A61B 18/18
A61F 9/007

Abstract:

A device for applying a bubble of a substance to a tissue surface, the device comprising a cannula, a distal tip at the distal end portion of the cannula, the distal tip having a bubble support surface and an exit port extending through the bubble support surface, an expansion fluid passageway extending through the cannula to the exit port, a source of an expansion fluid and an actuator therefor. In some arrangements, the distal tip can be configured to support a layer of the substance thereon over the distal port and the device can be configured such that the advancement of the expansion fluid from the fluid source through the exit port causes at least one bubble of the substance to form on the distal tip, wherein the at least a portion of the bubble can be transferred to the tissue surface to treat a defect on the tissue surface.
