Filed:

Sep 28, 2020

Appl. No.:

17/034707

Inventors:

- STEVENAGE, GB
Benjamin L. Ko - Cincinnati OH, US
Robert H. Roth - Cincinnati OH, US
Daniel J. Abbott - Maple Valley WA, US
Thomas E. Meyer - Philadelphia PA, US
Paul D. Gordon - Shreve OH, US

International Classification:

A61F 9/00
A61M 25/06
A61M 25/02

Abstract:

An apparatus includes a body, a needle, a catheter, and an actuator assembly. The needle extends distally from the body. The needle has an inner wall defining a needle lumen. The needle lumen is in fluid communication with a fluid port of the body. The catheter is slidably disposed in the needle lumen. The catheter has a catheter lumen. The first actuator assembly is configured to translate the catheter within and relative to the needle. The apparatus may also include an actuator assembly that is configured to rotate the needle relative to the body. The apparatus may be used to first deliver a leading bleb of fluid to the subretinal space in a patient's eye via the needle. The apparatus may then be used to deliver a therapeutic agent to the subretinal space in the patient's eye via the catheter.

International Classification:

A61F 9/00
A61B 17/34
A61F 9/007

Abstract:

An apparatus for delivering therapeutic agent to an eye comprises a body, a cannula, a hollow needle, a cannula actuation assembly, and a needle actuation assembly. The cannula extends distally from the body and is sized and configured to be insertable between a choroid and a sclera of a patient's eye. The cannula actuation assembly is operable to actuate the cannula relative to the body. The needle actuation assembly is operable to actuate the needle relative to the cannula. The cannula may be inserted through a sclerotomy to position a distal end of the cannula at a posterior region of the eye, between the choroid and sclera. The needle may be advanced through the choroid to deliver the therapeutic agent adjacent to the potential space between the neurosensory retina and the retinal pigment epithelium layer, adjacent to the area of geographic atrophy.
