Patent number: 7658746Abstract: A medical device that can be used to cut a cornea. The device may include a blade that is coupled to a head by a blade holder. The device may also have a retention spring that exerts a force on the blade and blade holder. The head and blade can be moved across a ring by a drive assembly that contains a lead screw. The ring may contain one or more openings which have a length that is greater than a width. The openings may be coupled to a vacuum source by a tube. The vacuum pressure of the tube can be displayed by a console. The console may also have switches that allow different operating parameters to be entered through a single knob.Type: GrantFiled: January 30, 2004Date of Patent: February 9, 2010Assignee: Med-Logics, Inc.Inventors: Rod Ross, Greggory Hughes

Publication number: 20040049217Abstract: A surgical cutting system. The cutting system includes a cutter which has an inner sleeve that moves adjacent to an aspiration port of an outer sleeve. The inner sleeve is coupled to a source of vacuum that pulls tissue into the outer port when the inner sleeve is moved away from the port. The inner sleeve then moves across the outer port and severs the tissue in a guillotine fashion. The tip of the inner sleeve may exert a spring force that assist in the cutting action of the cutter. The cutter includes a motor which creates an oscillating translational movement of the sleeve. The motor can be controlled by a controller that is coupled a foot pedal. The foot pedal and controller can be configured so that the motor decreases speed as the pedal is depressed by the operator. The inner sleeve is coupled to an aspiration line that pulls the severed tissue out of the cutter. The level of the aspiration vacuum pressure can be controlled by a variable regulator valve.Type: ApplicationFiled: September 2, 2003Publication date: March 11, 2004Inventors: Rod Ross, Greggory Hughes, James C. Boore, Thomas E. Reimer

Patent number: 6358260Abstract: A medical device that can be used to cut a cornea. The device includes a blade that is located within an opening of a ring. The ring can be placed onto a cornea. The device may further have a first drive mechanism that moves the blade in a first direction and a separate second drive mechanism that moves the blade in a second direction. The first drive mechanism may be controlled by a first input device. The second drive mechanism may be controlled by a second input device. The separate input devices and drive mechanisms may allow a surgeon to vary the shape and size of the corneal cut.Type: GrantFiled: April 20, 1998Date of Patent: March 19, 2002Assignee: Med-Logics, Inc.Inventors: Rod Ross, Greggory Hughes

Patent number: 5833643Abstract: A surgical tissue cutter. The cutter includes an inner sleeve that moves adjacent to an outer port of an outer sleeve. The outer port is coupled to a source of vacuum that pulls tissue into the outer port when the inner sleeve is moved away from the port. The inner sleeve then moves across the outer port and severs the tissue in a guillotine fashion. The inner sleeve is coupled to a rotating output shaft of a motor by a wobble plate which induces an oscillating translational movement of the sleeve in response to a rotation of the output shaft. The motor speed is controlled by a foot pedal which allows the surgeon to directly control the cutting speed of the device. The wobble plate can be replaced to vary the stroke and duty cycle of the inner sleeve. The inner sleeve is coupled to an aspiration line that pulls the severed tissue out of the cutter. The level of the aspiration vacuum pressure can be controlled by varying the speed of the motor and the movement of the inner sleeve.Type: GrantFiled: November 18, 1997Date of Patent: November 10, 1998Assignee: Scieran Technologies, Inc.Inventors: Rod Ross, Greggory Hughes, James C.
