Abstract: A surgical system for performing a capsulotomy of a lens capsule of an eye includes an elastic ring, a suction cup, an interface, a converter, and a control console. The elastic ring includes a conductive surface. The interface may be coupled to an air port and/or a fluid line of a phacomachine. The converter detects a pulse of air from the phacomachine via the interface, and produce an electrical signal in response. Fluid received from the phacomachine is delivered into the suction cup. The system is configured to remove the fluid from the suction cup and between the suction cup and a surface of the eye to form a suction seal. The control console is configured to, in response to receiving the electrical signal, drive a series of electrical pulses through the conductive surface of the elastic ring, causing the elastic ring to perform a tissue cutting operation.

Abstract: A design is described herein for rings and for cutting rings for a device used in capsulotomy procedures. A set of ring dimensions can describe a desired height of a ring at each location of the ring. The set of ring dimensions is also associated with an intended wall thickness, and thus is associated with an intended cross-sectional area at each ring location. A wall thickness at each portion of a can vary from the intended wall thickness specified by the set of ring dimensions at various locations of the ring. At these locations, the height of the ring can be varied such that the resulting cross-sectional area of the ring at these locations is substantially similar to the intended cross-sectional area of the ring at the locations.

Abstract: A device is described herein for performing capsulotomies that improves temperature uniformity and current flow around a cutting element of the device. The device includes a series of features whose geometries help remove cold and/or hot spots from the cutting element while maintaining the mechanical strength of the cutting element. In an embodiment, a device includes a cutting element and one or more electrical leads for providing an electrical discharge to the cutting element. The device further includes wire tabs configured to conductively couple an electrical lead to cutting element. Each wire tab includes a central conductive path and one or more conductive shunt paths conductively separated by one or more slots. The device further includes anchor tabs that are each associated with a slot disposed along the circumference of the cutting element and positioned to at least partially separate an anchor tab from a portion of the cutting element.

Abstract: Embodiments relate to a microsurgical device for concave topologies. The device enables operators to consistently cut uniform, circular, concentric concave and/or convex tissues. In an embodiment, a device for excising a tissue includes a stem, a suction cup connected to a distal end of the stem, and a cutting ring around an outer surface of the suction cup. The device further includes two suction tubes to provide suction to the suction cup and compress the outer surface of the suction cup against the tissue. The device may be connected to a control console configured to provide suction to the suction cup via the two suction tubes and electrical energy to the cutting element via one or more electrical leads. Through the control console, an operator of the device may control the depth of cut of the tissue by controlling the device parameters, such as the suction and electrical parameters.

Abstract: A device is described herein for performing capsulotomies that improves suction uniformity and produces rolled capsulotomy edges. The device includes a suction cup that forms a tapered circumferential suction chamber which enables suction to be applied to a tissue in a first direction. The tapered circumferential suction chamber decreases in cross-sectional area from a proximal end of the device towards a distal end of the device. The device further includes a stem coupled to the suction cup to provide suction to the suction cup. The stem forms a neck that enables fluid flow to the suction cup in a direction substantially perpendicular to the first direction. The device further includes a cutting element configured to excise the tissue.

Abstract: A surgical device and procedure are provided for performing microsurgery, including a capsulotomy of a lens capsule of an eye. The device has an elastically deformable cutting element mounted within an elastomeric suction cup. The suction cup is attached to an arm for manipulating the device. The device can be inserted into the anterior chamber of the eye, through a corneal incision, to cut a piece from the anterior portion of the lens capsule of the eye. The device is secured against the lens capsule using suction applied by one or more suction elements. The device is then removed from the eye, with the cut piece of membrane retained within the device by suction.

Abstract: A method for manufacturing a super elastic nitinol ring. The method includes compressing a nitinol wire on a first side and a second side to produce permanently flattened edges and cutting off a portion of the nitinol wire on a third side and a fourth side to produce flattened edges. The method includes producing a modified nitinol wire with a rectangular cross section formed by the flattened edges on the four sides, bending the modified nitinol wire into a ring shape such that a first end of the modified nitinol wire aligns with a second end of the modified nitinol wire; and permanently coupling the first end to the second end to produce a nitinol ring. The nitinol ring is coupled to a capsulotomy device such that the nitinol ring, upon receiving current flow from the capsulotomy device, produces heat sufficient to cut tissue in contact with the nitinol ring.

Abstract: A surgical device and procedure are provided for smoothly and easily accessing tissue to perform microsurgery, including a capsulotomy of a lens capsule of an eye. The device includes a handpiece with a tip for insertion into an incision in the cornea of the eye. A sliding element is disposed within the handpiece and a suction cup is mounted to the sliding element. The sliding element can be translated to move the suction cup into and out of the handpiece. A compression mechanism associated with the suction cup and the handpiece compresses the suction cup for deployment through the tip of the handpiece. The suction cup can expand inside the anterior chamber into a cutting position on the lens capsule. A cutting element mounted to the suction cup is used to cut a portion of the lens capsule and to remove the portion from the eye. The cutting element may be mounted to a cutting element support structure in a way that prevents heating of the device.
