09724191 · 2017-08-08 · ·

An intraocular lens inserter can include an energy storage portion, an actuator portion, and a lens support portion. The energy storage portion can include a compressible energy storage device, such as a compressible fluid, springs, and other devices. The inserter can include an actuator portion operating with a substantially incompressible fluid, such as liquids or other noncompressible fluids. The actuator can be configured to provide an operator with control over the release of energy from the energy storage portion so as to move a plunger for the discharge of a lens from an intraocular lens cartridge.

Plunger tip coupling device for intraocular lens injector
09763774 · 2017-09-19 · ·

The present disclosure is directed to devices, systems, and methods directed to mounting a plunger tip to a plunger of an IOL injection device. A plunger tip wrench that is operable to releasably retain a plunger tip may be coupled to a holder extending from an end of the IOL injection device to align the plunger tip with the plunger of the IOL injection device. In some instances, the IOL injection device may include a motor and use a back electromotive force (EMF) of the motor to detect a position of the plunger as it is extended to engage the plunger tip. The plunger tip may be positioned relative to the plunger such that the plunger will engage the plunger tip within the entire range of a negative error position and a positive error position.

Intraocular lens storage system
09763775 · 2017-09-19 · ·

An intraocular lens storage system for storing an intraocular lens. The intraocular lens storage system includes a storage container for storing the intraocular lens and an actuable transfer device, which is arranged in the storage container, with an intraocular lens receiver to receive the intraocular lens. The transfer device is movable between an intraocular lens storage position for storing the intraocular lens in the storage container and an intraocular lens transfer position to transfer the intraocular lens to an injection device.

GAS CANISTERS AND METHODS FOR MAKING THEM

Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.

HYDRAULIC DELIVERY OF SURGICAL IMPLANTS

An apparatus for delivering an implant to an eye using hydraulic fluid flow or pressure. An implant may be stored, advanced, and delivered to an eye using hydraulic fluid stored in a sterile container through a hollow advancement plunger. The plunger may rigidly advance the implant to a sealed position in a first phase, and then the implant may be advanced into the eye via hydraulic pressure or fluid flow in a second phase.

HYBRID POWER DELIVERY FOR SURGICAL IMPLANTS

A hybrid power system for delivering an implant to an eye using hydraulic fluid flow or pressure. An implant may be stored, advanced, and delivered to an eye using hydraulic fluid stored in a sterile container through a hollow advancement plunger. The plunger may rigidly advance the implant to a sealed position in a first phase, and then the implant may be advanced into the eye via hydraulic pressure or fluid flow in a second phase. The power system may provide a first cell having a first power density and a second cell having a second power density, wherein the second power density is greater than the first power density. A controller may use the first cell during the first delivery phase and the second cell during the second delivery phase.

HAPTIC MANAGEMENT FOR DELIVERY OF INTRAOCULAR IMPLANTS

An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, and an implant disposed in the implant bay. The implant may comprise an optic body, a leading haptic, and a trailing haptic. In some examples, the implant may be an intraocular lens. The apparatus may further comprise an actuator comprising a housing and a plunger disposed within the housing and a leading splay arm operable to splay the leading haptic within the implant bay. The plunger can be operable to advance the optic body from the implant bay to the delivery lumen after the leading splay arm straightens the leading haptic.

Cam-actuated optic lockout mechanism

Systems, methods, and devices, for delivery of a lens portion of a modular intraocular lens into an eye, may be provided. A device may include a housing; a nozzle positioned at an end of the housing, wherein an interior of the nozzle comprises a floor, the floor including an aperture; and a cam-actuated mechanism positioned within the housing, comprising: a lens stop comprising a base and a post, wherein the post is movably disposed within the aperture; and a slider configured to move in a direction toward the lens stop, wherein the lens stop is positioned at a distal end of the slider, the slider comprising a slot that is aligned with a portion of the base of the lens stop and configured to receive the portion of the base as the slider moves.

Cam actuated base folding mechanism

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. A device for delivery of the IOL into the eye may include a nozzle; a bay adjacent to the nozzle, wherein the bay is configured to contain the lens component and comprises a recess in a shape of a haptic extension; and a cam-actuated mechanism comprising a slider configured to move in a direction toward the nozzle; a side arm moveably disposed within the bay, wherein the side arm is positioned at an end of the slider, the end of the slider comprising a groove aligned with the side arm, wherein the groove extends from an outer edge of the slider into an interior portion of the slider, wherein the groove is angled to receive the side arm as the slider moves.

INTRAOCULAR LENS INJECTOR ASSEMBLY HAVING SHUTTLE ASSEMBLY RETAINING INTRAOCULAR LENS IN STORAGE VIAL AND OPERABLY PRESENTING INTRAOCULAR LENS IN INJECTOR ASSEMBLY

A shuttle, vial and injector are provided for storing and presenting an IOL to a patient. The shuttle includes operably engaged shuttle plates having a set of confronting surfaces that flex about a flexure interface between a storage configuration, with at least an optic of an IOL in a nominal state and a loading configuration, with at least an optic of an IOL in a deformed state. The vial engages the shuttle and maintains the shuttle in the storage configuration. The injector receives the shuttle from the vial and includes surfaces for flexing the portions of the shuttle plates to the loading configuration upon engagement with the injector, wherein the shuttle plates impart a predetermined curvature to at least a portion of the IOL.
