Patent number: 6793674Abstract: A band that can be implanted into an eye to re-attach a retina. The implanted band exerts a pressure that presses the retina into a globe of the eye. The band has a length that is at least 100 degrees of the circumference of the globe of the eye. The band may be injected into the eye with a syringe type injector.Type: GrantFiled: October 14, 2003Date of Patent: September 21, 2004Assignee: Scieran Technologies, Inc.Inventor: Ulises Zertuche Zapata

Patent number: 6629986Abstract: 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: GrantFiled: August 9, 2000Date of Patent: October 7, 2003Assignee: Scieran Technologies, Inc.Inventors: Rod Ross, Greggory Hughes, James C. Boore, Thomas E. Reimer

Patent number: 6176853Abstract: A medical system that includes a foot pedal which can be used to actuate a surgical instrument. The surgical instrument may be coupled to an actuator assembly and inserted into a cornea. The actuator assembly may be coupled to the foot pedal by a cable. The foot pedal may include a platform that can be depressed by a surgeon to move the cable and actuate the surgical instrument.Type: GrantFiled: November 5, 1998Date of Patent: January 23, 2001Assignee: Scieran Technologies, Inc.Inventor: Georgie E.

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.
