Patent number: 8172834Abstract: Illumination systems are described that can include one or more light sources, which can include LEDs, one or more lenses, and one or more optical fibers. A handheld, portable, and surgical intraocular illumination system is disclosed that is disposable, low-cost, and efficient. A surgeon can have direct control of turning the illuminator on and off and adjusting the intensity via a simple control ergonomically placed on the handpiece and/or voice activated control. A coupling is provided, such as through an endo-probe, which is coupled to the one or more light sources. A user input device can be included that is operable to transmit to a feedback controller a first signal based on a user-selected light intensity. The feedback controller can, in response to the first signal, transmit a second signal to the power source for altering the power provided by the power source to the illumination system.Type: GrantFiled: September 24, 2008Date of Patent: May 8, 2012Assignee: Doheny Eye InstituteInventors: Prashant R.

Patent number: 8172865Abstract: Apparatus, systems, and devices are described that utilize an adjustable biological tissue cutting handpiece that is based on selectable settings. The biological tissue cutting handpiece includes a cutter tip that allows multiple duty cycles as well as multiple port configurations. For example, when working next to the retina, the port could be adjusted to be a smaller size, allowing delicate membrane dissection. When working near or in less sensitive tissue, e.g. the center of the eye, the port could be wide open. The port aperture size can be independent of cut speed, allowing a surgeon to work at high speed both next to the retina and away from the retina. High speeds have been shown to have increased tissue (e.g., vitreous) removal, e.g., in 25 and 23-gauge instruments. Duty cycle is not necessarily dependent on cut speed, allowing high cutter performance and varied flow characteristics.Type: GrantFiled: September 29, 2008Date of Patent: May 8, 2012Assignee: Doheny Eye InstituteInventors: Charles DeBoer, Matthew McCormick, Prashant R. Bhadri, Aaron Barnes, Ralph Kerns, Mark S. Humayun

Publication number: 20120022434Abstract: Disposable handheld phacomorcellation devices and methods for removing lens fragments from an eye of a patient are disclosed. In one embodiment, the phacomorcellation device includes a stationary outer tubular cutting member and a rotatable inner cutting member positioned within the stationary outer tubular cutting member. The outer tubular cutting member and the rotatable inner cutting member each include at least one cutting port having at least one cutting edge. The at least one cutting edge of the outer tubular cutting member and the at least one cutting edge of the inner cutting member cooperate to form a bird beak cutting structure as the inner cutting member rotates with respect to the outer cutting member. The cutting port of the outer tubular cutting member can be substantially closed during rotation of the inner cutting member, thereby preventing lens fragments from floating toward a posterior region of the eye.Type: ApplicationFiled: April 7, 2010Publication date: January 26, 2012Applicant: DOHENY EYE INSTITUTEInventors: Jaw-Chyng Lormen Lue, Matthew McCormick, Ralph Kerns

Publication number: 20110276340Abstract: A personal surgical center embodied as a general purpose computer (e.g. laptop) with wireless technology for monitoring the operation of an independent surgical center and/or handheld instruments. The computer tracks procedures in the operating room and instruments used during those procedures, and accounts for billing, supply management, and payment options. The monitoring of the instruments used during the surgery is conducted by the personal surgical center while actual control of the settings of those instruments is via the independent surgical center or via controls included in the instruments themselves. The monitored information is stored in a log file which is then transmitted to a hospital server for generating reports, inventory control, billing, and the like. Other information generated during the procedure (e.g. doctor notes) is also stored in the log file.Type: ApplicationFiled: April 11, 2011Publication date: November 10, 2011Applicant: DOHENY EYE INSTITUTEInventors: Charles DeBoer, Matthew McCormick, Ralph Kerns, Prashant Bhadri, Lawrence Chong, Mark Humayun

Publication number: 20080208233Abstract: Electric vitrectomy handpieces are provided. The handpiece includes a motor, a clutch mechanism, an oscillating drive mechanism, a cutting tip and a handle. The motor is attached to the clutch, and the clutch is attached to the oscillating drive mechanism. When the motor is operational, the clutch expands to engage the oscillating drive mechanism and the oscillating drive mechanism converts the rotational motion of the clutch to the reciprocating motion of the cutting tip. When the motor is at rest, the clutch retracts to allow aspiration.Type: ApplicationFiled: December 21, 2007Publication date: August 28, 2008Inventors: Aaron Barnes, Charles De Boer, Matthew McCormick
