20080312594 | VACUUM SURGE SUPPRESSOR FOR SURGICAL ASPIRATION SYSTEMS - An apparatus and method to suppress vacuum surges in a surgical aspiration system is disclosed and claimed. A vacuum surge suppressor includes a first fluid path for coupling to a surgical instrument, and a filter attached to the first fluid path. A flow restrictor is coupled to the filter with the filter disposed upstream of the flow restrictor. The vacuum surge suppressor also includes a second fluid path for coupling to a vacuum pump. The second fluid path is connected to the flow restrictor and disposed downstream of the flow restrictor. The second fluid path defines a path internal pressure. A third fluid path is coupled to the filter and is connected to the second fluid path, bypassing the flow restrictor. A valve in the third fluid path obstructs flow in the third fluid path in response to the path internal pressure. | 12-18-2008 |

A shaft distal end has a driver face facing away from an interior of the C-shape, and defining a driver face diameter that is preferably no less than 50% of the pin cap diameter. | 06-21-2012 |
20130253557 | SURGICAL INSTRUMENT RINGING A TITANIUM NEEDLE WITH A NODE OF MINIMUM AMPLITUDE IN A SUBSTANTIALLY CYLINDRICAL PORTION OF THE NEEDLE - A surgical instrument and method, for example to accomplish phacoemulsification, are disclosed. The surgical instrument includes a handpiece that has a piezoelectric transducer, and a titanium needle having a free distal tip and a supported end that is attached to the handpiece. The titanium needle has a substantially cylindrical portion with an outer diameter in the range 0.5 mm to 1.5 mm and a length in the range 12 mm to 37 mm. A circuit drives the piezoelectric transducer to periodically longitudinally expand and longitudinally contract at a driving frequency. The driving frequency is selected to ring the titanium needle with a standing wave that is characterized by longitudinal expansion and longitudinal contraction, the standing wave having a distal node of minimum amplitude in the substantially cylindrical portion. | 09-26-2013 |

20140261445 | RECTOCELE AND CYSTOCELE DEVICE - A recto-cystocele device to address rectocele and cystocele disorder is described. The device generally comprise a handle and a paddle that are distinguished from one another by a bend in the recto-cystocele device which forms essentially an L-shaped unit, the bend possessing a sufficient radius to avoid contact with a pelvic region of the woman and the recto-cystocele device. The device further comprises an expandable sheath located on the paddle that after being inserted in a vagina of the woman and is expanded therein is in contact with at least an upper portion of the vagina that includes a posterior fornix of the vagina and a lower portion of the vagina that does not include the posterior fornix. The handle, which does not go into the vagina, is adapted to be manually manipulated by the woman to translate directional pressure against the posterior fornix and the lower portion of the vagina via the expandable sheath when expanded. | 09-18-2014 |
