Abstract: An extraction device can include a delivery shaft having a lumen and a distal end, a first wire forming a first arc and being positionable distal to the distal end of the delivery shaft while ends of the first arc are at a distalmost end of the delivery shaft, and a second wire forming a second arc and being positionable distal to the distal end of the delivery shaft while ends of the second arc are at the distalmost end of the delivery shaft. A distalmost extent of the first wire is distal to a distalmost extent of the second wire. The first wire and the second wire are separately retractable relative to the delivery shaft.

Abstract: An intraocular drainage device may include a monolithic silicone body having a flap, a rigid bottom plate having a portion configured to contact a corresponding portion of the flap, and a tube having a proximal end disposed between the flap and the rigid bottom plate. The corresponding portion of the flap may be configured to separate from the portion of the rigid bottom plate responsive to a fluid pressure in aqueous humor received from the tube. A plurality of parallel microgrooves may be formed on one or more portions of one or more outer surfaces of the intraocular drainage device.

Abstract: Intraocular drainage devices and methods of making intraocular drainage devices are disclosed. A disclosed intraocular drainage device includes a tube having a distal end and a body disposed proximal to the tube. A central inlet port is disposed on the distal end of the tube and extends lengthwise internally through the tube. A central outlet port is disposed on the proximal end of the body and extends lengthwise internally through the body. Multiple transverse inlet and outlet ports are coupled to the central inlet and outlet ports, respectively. The central and transverse inlet ports are configured to receive influent fluid from an anterior chamber of an eye and the central and transverse outlet ports are configured to output the influent fluid external to the anterior chamber of the eye. Intraocular drainage and core assemblies and methods of making intraocular drainage devices are also disclosed.

Abstract: Apparatus and methods for cataract extraction are disclosed. An extraction device may include a delivery shaft having a lumen and a distal end. The lumen may include a first channel and a second channel diverging at the distal end. A wire may form a loop and extend from the first channel and the second channel. The wire may be movable within the lumen.

Abstract: Intraocular drainage devices, intraocular implantation procedures, and inserter devices for intraocular implantation procedures are disclosure. A disclosed intraocular drainage device includes a tube having a distal end and a body disposed proximal to the tube. An inlet port is disposed on the distal end of the tube and configured to receive an influent fluid from an anterior chamber of an eye. An inlet fluid pathway is coupled to the inlet port and extends at least partially through the tube. A plurality of outlet fluid pathways extend at least partially through the body and branch from the inlet fluid pathway. A plurality of outlet ports are disposed on the body and coupled to the plurality of outlet fluid pathways. A disclosed inserter device for an ocular implantation procedure includes a handle, a needle, and a plunger. The needle is disposed on a distal end of the handle and configured to hold an intraocular drainage device. The plunger is coupled to the needle and disposed in the handle.
