Publication number: 20190183674Abstract: A system for storing and delivering a predetermined amount of fluid includes a syringe including a barrel, a flange disposed at the proximal end of the barrel, and a plunger assembly configured to be received in the lumen of the barrel. The plunger assembly includes a piston and a plunger rod. The plunger rod is removably couplable to the piston at the distal end of the plunger rod and includes a thumb press flange at the proximal end of the plunger rod. The system further includes a stop feature that is removably couplable to the syringe or the plunger assembly. The stop feature is configured to arrest distal advancement of the plunger assembly relative to the syringe when the plunger assembly reaches a predetermined position relative to the syringe. The stop thus ensures that a predetermined amount of fluid remains in the barrel.Type: ApplicationFiled: February 25, 2019Publication date: June 20, 2019Inventors: Mark C. Tsai, Brian M. Gatton, JR., Michael F. Keane, Isaac J. Khan, Brendan J. Oberkircher, Daniel W. Price

Patent number: 10322028Abstract: An apparatus for delivering therapeutic agent to an eye comprises a body, a cannula, a hollow needle, an actuation assembly, and a detection/visualization system. 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 actuation assembly is operable to actuate the needle relative to the cannula to thereby drive a distal portion of the needle along an exit axis. The cannula may be inserted through a sclerotomy incision and advanced through the choroid to deliver the therapeutic agent adjacent to the potential space between the neurosensory retina and the retinal pigment epithelium layer. The detection/visualization system is operable to detect or visualize penetration of the choroid of a patient's eye and provide feedback to the operator and/or automatic control of the apparatus based on penetration of the choroid.Type: GrantFiled: September 1, 2015Date of Patent: June 18, 2019Assignee: ORBIT BIOMEDICAL LIMITEDInventors: Daniel W.

Publication number: 20180256394Abstract: A method includes inserting a flexible cannula between a sclera and a choroid of an eye. The needle is advanced from a distal end of the flexible cannula, such that the needle pierces the choroid to access a subretinal space of the eye. The needle is used to aspirate fluid from the subretinal space. The fluid may be present from a retinal detachment, a macular hemorrhage, or other condition present before the procedure begins. The method may further include injecting the fluid in the subretinal space via the needle, in which case the fluid may be a balanced salt solution or other bleb fluid. The method may further include injecting a therapeutic agent into the subretinal space after aspirating the bleb fluid. The volume of injected bleb fluid may be greater than the volume of injected therapeutic agent.Type: ApplicationFiled: March 5, 2018Publication date: September 13, 2018Inventors: Daniel W. Price, Brendan J. Oberkircher, Daniel J. Prenger, Geoffrey King, Isaac J. Khan, Michael F. Keane, Benjamin L. Ko
