Abstract: A system and method of receiving a cassette to a console of a phacoemulsification system. The system and method may include receiving the cassette in close proximity to a cassette receptacle comprising a receiving surface, sensing variations in at least two variable resistances mounted respectively diagonally about the receiving surface, and comparing the variations as between the at least two variable resistances to assess an attitude of the cassette. The system and method may optionally include clamping the cassette responsively to the comparing step.

Abstract: A surgical system includes a replaceable surgical cassette that is configured to be received by a surgical console, the surgical cassette permitting fluid flow through the cassette, the surgical system controlling the flow of fluid through the cassette via one or more flexible valves actuated by one or more actuation plungers located on the surgical console. The one or more flexible valves of the surgical cassette and the one or more actuation plungers of the surgical console include a positioning feature configured to assist with positioning the one or more actuation plungers to apply uniform and symmetric pressure to the one or more valves during actuation.

Abstract: A surgical cassette for use with a phacoemulsification system having a front housing; and a fluid manifold having an at least partially unibody construction and being removably coupled to at least the front housing. The fluid manifold having molded fluid channels. A surgical system, having a console, a handpiece, and a cassette that couples the handpiece with the console, wherein the cassette has a front housing, a fluid manifold and a drain bag assembly; wherein the fluid manifold has a unibody construction and is removably coupled to at least the front housing and drain bag assembly.

Abstract: Eliminating leaks of molded fluid channels by providing a front housing, rear housing, and a gasket, wherein the front housing has one or more molded fluid channels and one or more seal channels, and wherein at least a portion of the gasket is located between the front and rear housing; molding the gasket onto the rear housing to create a single unit, wherein the gasket has one or more seal lips configured and dimensioned to couple with the one or more seal channels; and assembling the front housing to the rear housing having the gasket, wherein the one or more seal lips couple with the seal channels. A surgical cassette manifold having a front and rear housing, and a gasket therebetween. The front housing having molded fluid channels that mate with the gasket and the gasket having multiple valves and a sensor/diaphragm accessible through the rear housing.

Abstract: A phacoemulsification surgical console, and a related system and method. The console, system and method may include a cassette receiver suitable for receiving a surgical cassette, a controller suitable for controlling provided aspects of the phacoemulsification; and a pre-alignment feature along a lower portion under and proximate to the cassette receiver, extending outwardly from the lower portion, and suitable for aligning the surgical cassette to the cassette receiver. The pre-alignment feature may comprise a shelf.

Abstract: A tray assembly includes an articulatable arm assembly coupled with a tray and selectively held in place by a locking mechanism (e.g., a locking gas spring). A release mechanism coupled with the tray selectively activates and deactivates the gas shock mechanism and is coaxial with and free rotating with respect to an axis of rotation of the tray. The tray may rotate between a horizontal position and a stored position substantially orthogonal to the horizontal position. The arm assembly may include at least one frictional hinge comprising a tapered pin, a tapered bushing in rotational frictional contact with the tapered pin, and an adjustment mechanism coupled to the tapered pin to provide adjustable contact force between the tapered pin and the tapered bushing.

Abstract: An interface for coupling an eye to a surgical laser is disclosed. A lens cone includes a base ring opposite an apex ring. The base ring defines a first plane and is adapted to couple to the delivery tip of the laser such that the first plane has a predetermined position relative to the delivery tip. An applanation lens is affixed to the apex ring and has a surface disposed in a second plane such that the second plane is parallel to and has a predetermined position relative to the first plane. A gripper is engagable with the lens cone. An attachment ring is affixed to the gripper and is adapted to couple to the anterior surface of the eye. When the lens cone and gripper are engaged, the applanation lens contacts the anterior surface of the eye, placing the anterior surface in spatial registration with the delivery tip.

Abstract: A method for applanating an anterior surface of a cornea and coupling the eye to a surgical laser is disclosed. A interface is provided which has a central orifice and top and bottom surfaces. A suction ring is removably coupled to the bottom surface of the interface. The interface is positioned over an operative area of an eye, such that the suction ring comes into proximate contact with the surface of the eye. A suction is applied to the suction ring to stabilize the position of the interface relative to the operative area of the eye. An applanation lens is positioned in proximate contact with the operative area of the eye. Finally, the applanation lens is coupled to the interface to stabilize the position of the lens relative to the operative area of the eye.

Abstract: A disposable stabilization and applanation device for reconfiguring the cornea of an eye for ophthalmic laser surgery, includes an applanation lens that is disposed in a particular spatial position with respect to an incident laser beam. The applanation lens is inserted into the central opening of an attachment ring and applanates the eye in response to pressure from a lens cone. The attachment ring is coupled to the eye and includes a skirt which surrounds the applanation lens and extends outwardly therefrom to define a chamber. The skirt is formed with a groove which defines a suction channel between the attachment ring skirt and the corneal surface of an eye. A vacuum source is connected and fluid communication with the suction channel and is selectively activated to create a partial vacuum in the channel.
