A61B018/18

US Classification:

606/004000, 606/015000

Abstract:

An ophthalmic illumination device () includes a source of light () that has a spectrum primarily in a red spectrum and is substantially devoid of spectra in any other color, including a blue spectrum and a green spectrum. The red light is provided by a red light emitting diode () and may be used in combination with known ophthalmic illumination devices that provide a white light (). A surgeon controls the device and can switch () between the red light () and the white light ().

International Classification:

A61F 9/007

US Classification:

606166

Abstract:

An injector for performing a capsulotomy on a capsular bag, comprising an injector body, an injector nozzle coupled to the injector body, the injector nozzle having a lumen extending therethrough ending in an open tip, a strand of shape-memory material adapted to achieve a predetermined shape when ejected from a tip through an opening, a heating unit coupled to the strand to cause the strand to achieve an elevated temperature.

International Classification:

A61F 9/007
A61M 1/00

US Classification:

604 31, 604 66

Abstract:

An ophthalmic surgical apparatus for use with an eye including a tube adapted to be in fluid communication with the eye, a pressure sensor adapted to measure an intraocular pressure value of the eye, a fluid reservoir comprising a moveable wall, the fluid reservoir adapted to be in fluid communication with the eye through the tube, and at least one processor coupled to the pressure sensor to receive the measured intraocular pressure value, the at least one processor operable to position the moveable wall in response to a difference between the measured intraocular pressure value and a target intraocular pressure value.

Assignee:

BAUSCH & LOMB INCORPORATED - Rochester NY

International Classification:

A61F 9/007

US Classification:

604 22, 604264

Abstract:

An ophthalmic surgical device includes a housing having a distal end and a proximal end . A cannula is attached to the housing distal end and has a distal tip with at least one port in communication with a lumen extending through the cannula and in communication with an aspiration path in the housing . A vibration source is held within the housing for vibrating the distal tip for assisting in vitreous and other tissue removal. An aspiration source connected to the aspiration path for applying a negative pressure to the lumen and the at least one port for removing fluids and the vitreous and other tissue from the eye. The vibration source and the aspiration source together create a periodic bi-directional flow of tissue through the port without creating cavitation externally of the distal tip

International Classification:

A61F 9/007

Abstract:

A phacoemulsification transducer assembly includes a reflector and a driver connected to the reflector. The driver has a known driver vibration frequency range. A horn is connected to the driver opposite the reflector. A needle is connected to the horn opposite the driver. The needle has a known free shaft length. To maximize a desired stroke length of the needle for a minimal amount of power applied to the driver, a material forming the needle is chosen such that a speed of sound through the material results in a quarter-wavelength distance at the driver vibration frequency range substantially equal to the needle free shaft length.

Matthew J. Fitzgerald - St. Louis MO, US

International Classification:

A61F 9/007

Abstract:

A phacoemulsification needle includes a hub for connection to an ultrasonic handpiece. An elongated shaft is formed with the hub and extends from the hub. A distal end of the shaft breaks-up tissue when the distal end is caused to be vibrated by the handpiece. At least a distal portion of the shaft is formed of a material that has properties providing advantages compared to a metal needle. Example properties include a substantially lower density, a substantially higher electrical resistivity, a substantially lower thermal conductivity, a substantially lower mechanical lateral stiffness, a substantially higher efficiency of converting electrical energy powering the handpiece into motion of the distal end, a substantially lower acoustical impedance, a substantially higher Poisson's ratio, and a substantially higher mechanical gain.
