  • Patent number: 11801163
    Abstract: A medical device for removing lens tissue from inside a capsular bag of an eye including a cam assembly operatively coupled to a vacuum generation source positioned within the housing. A first portion is operatively coupled to the vacuum generation source and a second portion is operatively coupled to the first portion and to the shaft. The first portion is capable of rotating about an axis to cause the vacuum generation source to generate vacuum through the lumen. The second portion is capable of rotating about the axis with the first portion to cause the shaft to oscillate. A first degree of actuation of a trigger causes the vacuum generation source to generate vacuum within the lumen of the shaft, and a second degree of actuation of the trigger causes the shaft to oscillate as the second portion rotates. Related systems, devices, and methods are provided.

  • Patent number: 11730625
    Abstract: A device for performing an ophthalmic procedure in an eye including a hand-held portion; an elongate member extending from a distal end region of the hand-held portion; and an aspiration pump within the hand-held portion. The elongate member includes a lumen and an opening near a distal end region of the elongate member. The aspiration pump is in fluid communication with the opening of the elongate member. The aspiration pump includes a camshaft extending along a longitudinal axis and having a plurality of lobed cams; tubing extending parallel to the longitudinal axis; and a plurality of cam followers driven by the cams of the camshaft to move in a plane perpendicular to the longitudinal axis to sequentially compress the tubing. Related devices, systems, methods are provided.

  • Patent number: 11723802
    Abstract: A hand-held aspiration device is provided which has a relatively small suction volume along a suction path to improve responsiveness of the aspiration device when the device is activated. The device may be manually powered and may be provided without electronic controls. The device has a suction path which may be purged into a disposal enclosure to reduce the volume of material under the influence of the suction pressure during the procedure. The suction source may also be part of the hand-held unit to further reduce the suction path and suction volume.

  • Patent number: 11723803
    Abstract: An exemplary surgical device includes a shaft with a lumen defined therethrough and an element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen; wherein motion from the stored position to the deployed position causes a first leg of the element to advance distally relative to the distal end of the shaft, and causes a second leg of the element to move proximally relative to the distal end of the shaft.

  • Patent number: 11638660
    Abstract: A system for extracting lens material from an eye including an instrument having a first aspiration pump driven by a drive mechanism having a motor, and an elongate member sized and configured to extend through an anterior chamber to a capsular bag of the eye. The elongate member configured to be oscillated by the drive mechanism includes an inner lumen fluidly coupled to the first aspiration pump and defining at least a portion of an aspiration waste line, and an open distal end having a distal cutting tip. The system can further include a fluid system remote from the surgical instrument including a second aspiration pump and a fluid line configured to deliver background aspiration from the second aspiration pump to the inner lumen of the elongate member to aspirate the lens material from the eye towards the inner lumen. Related devices, systems, and methods are also provided.

  • Patent number: 11622887
    Abstract: Devices, systems, and methods for performing an ophthalmic procedure in an eye are disclosed. The devices include a hand-held portion and a distal, elongate member coupled to the hand-held portion having a lumen operatively coupled to a vacuum source. A drive mechanism operatively coupled to the elongate member is configured to oscillate the elongate member. When in use, the device is configured to aspirate ocular material from the eye through the lumen. The drive mechanism retracts the elongate member with a retraction speed profile and advances the elongate member with an extension speed profile. The retraction speed profile is different from the extension speed profile.
