Patent number: 11554042Abstract: An apparatus for delivering therapeutic agent to an eye comprises a body, a cannula, a hollow needle, and an 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 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 that is obliquely oriented relative to the longitudinal axis of the cannula. The cannula may be inserted through a sclerotomy incision 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.Type: GrantFiled: November 8, 2018Date of Patent: January 17, 2023Assignee: Gyroscope Therapeutics LimitedInventors: Brendan J. Oberkircher, Daniel W. Price, Michael F. Keane, Saeed Sokhanvar, Daniel J. Yasevac, Michel G. Bruehwiler, Leah R. Soffer, Isaac J. Khan, Benjamin L. Ko, Christopher D. Riemann, Nathan D. Grubbs

Patent number: 11517773Abstract: An apparatus for operating on tissue includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body and includes an acoustic waveguide. The waveguide is configured to acoustically couple with an ultrasonic transducer. The end effector includes an ultrasonic blade, a clamp arm, and a clamp pad. The blade is in acoustic communication with the waveguide. The clamp arm is configured to pivot about a first pivot point toward and away from the ultrasonic blade and includes a coupling feature. The clamp pad is selectively attachable to the blade to acoustically isolate the clamp arm from the ultrasonic blade. The coupling feature of the clamp arm is configured to provide a snap fit between the clamp pad and the clamp arm and thereby permit manipulation of the clamp pad for removal of the clamp pad from the clamp arm.Type: GrantFiled: August 23, 2019Date of Patent: December 6, 2022Assignee: Cilag GmbH InternationalInventors: Benjamin D. Dickerson, Kristen G. Denzinger, Ryan M. Asher, Collin J. Loch, Nathan D. Grubbs, Daniel J. Prenger, Laura A. Boehm

Publication number: 20220240971Abstract: A surgical apparatus comprises a transducer assembly and a shaft assembly. The transducer assembly is operable to convert electrical power into ultrasonic vibrations. The shaft assembly comprises an ultrasonic waveguide, a sheath, a shroud, and a torque transfer assembly. The waveguide is configured to couple with the transducer assembly. The waveguide is disposed within the sheath. The sheath extends through the shroud. The torque transfer assembly is contained within the shroud. The torque transfer assembly is configured to transfer a predetermined range of torque from the shroud to the waveguide to thereby couple the waveguide with the transducer assembly. The torque transfer assembly is further configured to prevent transfer of torque from the shroud to the waveguide beyond an upper limit of the predetermined range.Type: ApplicationFiled: February 16, 2022Publication date: August 4, 2022Inventors: Cory G. Kimball, David A. Witt, William E. Clem, Nathan D. Grubbs, Daniel J. Prenger
