Patent number: 9233021Abstract: In various embodiments, a phacoemulsification cutting tip with a straight shaft and an angled portion off of the straight shaft may include a hook on the angled portion to move an axis of rotation of the cutting tip closer to alignment with an extended centerline of the shaft. The cutting tip may be configured to torsionally rotate back and forth on an axis perpendicular to a centerline of the shaft (e.g., rotation around a y-axis). In some embodiments, lateral vibrations (e.g., side to side along an x-axis or z-axis perpendicular to the y-axis) that result from torsional rotation around the y-axis in a cutting tip without the hook may be reduced through use of the hook to balance the otherwise eccentrically weighted hook.Type: GrantFiled: October 24, 2013Date of Patent: January 12, 2016Assignee: Alcon Research, Ltd.Inventors: Alexander N. Artsyukhovich, Mikhail Boukhny, James Y. Chon, Ramon Carsola Dimalanta, Jr.

Patent number: 8631831Abstract: In various embodiments, aspiration tubing connecting a handpiece to a surgical console may include a high compliant section, a transition section, and a low compliant section. In some embodiments, the high compliant section may have a lower durometer and/or different geometry than the low compliant section. The transition section may take a number of forms, including a connector or a continuous section of tubing that gradually increases in durometer and/or changes geometry through the length of the tubing. In the various embodiments, the high compliant section may provide flexibility near the handpiece to make the handpiece easier to hold and maneuver while the low compliant section may reduce the effects of occlusion break surge. In some embodiments, the high compliant section may include, for example, ribs, stiffening rings, a stiffening sleeve, or a stiffening sock to increase the stiffness of the high compliant section.Type: GrantFiled: August 12, 2009Date of Patent: January 21, 2014Assignee: Alcon Research, Ltd.Inventors: Ramon Carsola Dimalanta, Jr., Grace Chuang Liao, Robert Harry Peterson

Publication number: 20110144641Abstract: A high-intensity pulsed electric field (HIPEF) vitrectomy apparatus is disclosed. An exemplary apparatus includes a HIPEF probe comprising at least one electrode disposed at a distal end of the HIPEF probe, such that the distal end is configured for insertion into an eye. Various embodiments include a probe shaft assembled from a modular end segment and one or more additional modular shaft segments, each of the modular end segment and one or more modular shaft segments in turn comprising at least two longitudinal channels adapted to accommodate an electrode unit. In some of these probe shafts, each of the modular end segment and one or more modular shaft segments has a central longitudinal channel, and the probe shaft further comprises an aspiration tube disposed within the central longitudinal channel.Type: ApplicationFiled: December 14, 2010Publication date: June 16, 2011Applicant: ALCON RESEARCH, LTD.Inventors: Ramon Carsola Dimalanta, JR., Tammo Heeren, John Christopher Huculak, Steven W.

Publication number: 20110112466Abstract: In various embodiments, a phacoemulsification tip may be configured with a proximal end configured to be secured to a phacoemulsification hand piece and a distal end shaped as a five-sided polygon with five corners. In some embodiments, at least two of the five corners of the five-sided polygon may form a right angle and one of the five corners may form a dominant point spaced further from an axis of rotation of the five-sided polygon than any of the other four corners. For example, the distal end may be shaped in a home base configuration. The displacement of the dominant point from the axis of rotation may improve cutting and/or improve the removal of lens material. In some embodiments, the dominant point may form a sharper edge than at least one of the other four corners (e.g., the other four corners may be rounded).Type: ApplicationFiled: November 11, 2009Publication date: May 12, 2011Inventor: Ramon Carsola Dimalanta
