Patent number: 11801163Abstract: 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.Type: GrantFiled: May 15, 2020Date of Patent: October 31, 2023Assignee: Carl Zeiss Meditec Cataract Technology Inc.Inventor: Michael Schaller

Patent number: 11723802Abstract: 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.Type: GrantFiled: March 6, 2020Date of Patent: August 15, 2023Assignee: Carl Zeiss Meditec Cataract Technology Inc.Inventors: Luke W.

Patent number: 11638660Abstract: 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.Type: GrantFiled: June 4, 2019Date of Patent: May 2, 2023Assignee: Carl Zeiss Meditec Cataract Technology Inc.Inventors: Casey Balkenbush, Peter Bentley, Luke W.

Patent number: 11622887Abstract: 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.Type: GrantFiled: June 10, 2019Date of Patent: April 11, 2023Assignee: Carl Zeiss Meditec Cataract Technology Inc.Inventors: Scott Chamness, Luke W.
