Patent number: 8287484Abstract: In one aspect of the invention, a multi-purpose phacoemulsification needle comprises a needle body disposed about a centerline and has a lumen disposed therein. The lumen has a first cross-sectional area that is normal to the centerline. The needle further comprises a distal tip comprising an arcuate surface and a face with a port therein. The port has a second cross-sectional area in a plane generally parallel to the face and is in fluid communication with an internal cavity that has a third cross-sectional area normal to the centerline, the internal cavity being in fluid communication with the lumen. The needle is configured such that the third cross-sectional area is greater than either the first cross-sectional area or the second cross-sectional area. In another aspect of the invention, the needle comprises a plurality of fins projecting inwardly from the lumen.Type: GrantFiled: May 2, 2006Date of Patent: October 16, 2012Assignee: Abbott Medical Optics Inc.Inventor: Paul W.

Publication number: 20090118663Abstract: A method and apparatus for performing a surgical procedure is provided. The surgical procedure may be a phacoemulsification procedure but other procedures may employ the techniques disclosed. The design includes sensing, within the surgical site, for a material change in fluid flow relative to a predetermined threshold. Upon sensing the fluid flow materially differs from the predetermined threshold, the design temporarily increases aspiration vacuum pressure to the surgical site above a predetermined upper threshold toward a maximum vacuum level. The design applies electrically generated disruptive energy, including but not limited to laser and/or relatively low power ultrasonic energy, to the surgical site from a first point in time measured from when aspiration vacuum pressure is above the predetermined upper threshold to a second point in time where pressure falls below a predetermined lower threshold.Type: ApplicationFiled: January 24, 2008Publication date: May 7, 2009Applicant: Advanced Medical Optics, Inc.Inventors: Paul W.
