  • Patent number: 10492873
    Abstract: A system and method for medical spatial orientation is disclosed including a robotic arm; an image sensor coupled to the robotic arm; a visualization headset; and a computing subsystem coupled to the robotic arm and the visualization headset. The computing subsystem includes a processor; a non-transitory machine-readable medium communicatively coupled to the processor; and instructions stored on the non-transitory machine-readable medium that, when loaded and executed by the processor, cause the processor to create a first image of a first portion of a surgical field at an image sensor coupled to the robotic arm; detect a movement of a visualization headset indicating a second portion of the surgical field; determine a movement of the robotic arm to position the image sensor at the second portion of the surgical field; move, based on the determination, the robotic arm; and create a second image of the second portion of the surgical field.

  • Patent number: 10292783
    Abstract: An ophthalmic illumination system includes a light source generating a source light beam and a beam splitter splitting the source light beam into first and second light beams. A first attenuator is located in a path of the first light beam and a second attenuator is located in the path of the second light beam, the first and second attenuators operable to change the intensities of the first and second light beams, respectively. A first optical fiber port is configured for connection to a first optical fiber for delivering the first light beam to a patient's eye and a second optical fiber port is configured for connection to a second optical fiber for delivering the second light beam to the patient's eye. A control unit is communicatively coupled to the first and second attenuators and is operable to adjust the attenuators to control the intensities of the light beams delivered to the patient's eye.

  • Patent number: 8109937
    Abstract: A surgical system includes a surgical instrument, an aspiration flow rate measurement device, a vacuum force measurement device, and an indicator. The surgical instrument has an aspiration portion and is located in a media type. The aspiration flow rate measurement device is configured to measure the flow rate generated by the aspiration portion. The vacuum force measurement device is configured to measure the vacuum force generated by the aspiration portion. The indicator provides an indication of the media type in which the surgical instrument is located. The indication is based on aspiration flow rate measurement information, vacuum force measurement information, and an operation and configuration of the surgical instrument.

  • Publication number: 20110288525
    Abstract: Aspects of forming a wound-conforming pressure seal in the eye, such as upon completion of an ocular surgical procedure, are described herein. Forming the seal includes introducing a plug member into an opening formed in the eye to block vitreous from exiting from the eye through the opening. Consequently, the seal is operable to substantially reduce or eliminate hypotony (i.e., lowering of intraocular pressure below safe levels) and/or endophthalmitis (i.e., infections to the eye).

  • Publication number: 20100106083
    Abstract: The present invention is a method of operating an ophthalmic hand piece. A connection between a tip segment and a limited reuse assembly is recognized. A type of tip segment connected to the limited reuse assembly is determined. Dosage information is received. A first input is received. In response to the first input, a heater is activated to heat a substance contained in a dispensing chamber. After the substance has reached a desired temperature range, the dosage information is used to control a distance a plunger travels. A second input is received. In response to the second input a motor is activated, and the drug is delivered into the eye.

  • Publication number: 20080021419
    Abstract: A method of injecting a substance into an eye is disclosed. A connection between a disposable tip segment and a limited reuse assembly is recognized. A temperature control device is activated to alter the temperature of a substance contained in a dispensing chamber. Dosage information is read. In response to the dosage information, a mechanical linkage interface is advanced to advance a plunger to expel the substance from the dispensing chamber. The mechanical linkage interface is retracted without substantially retracting the plunger to prevent reflux of the substance. Reuse of the disposable tip segment is prevented. The removal of the disposable tip segment from the limited reuse assembly is recognized.

  • Patent number: 6863073
    Abstract: Featured is a device for puncturing tissue of a body, such as the lamina cribosa and methods for treating a CVRO with such a puncturing device. The puncturing device includes a puncture member being generally configured and arranged to locally disrupt tissue proximal an area of the puncture site, to minimize the potential for damage to body parts or tissue immediately adjacent to this area of the puncture site and to facilitate perforation of the tissue at the puncture site. When the lamina cribosa is being punctured, the puncture member is more particularly configured and arranged to locally disrupt connective tissue of the lamina cribosa proximal to and surrounding the central retinal vein while minimizing the potential for structural damage to the central retinal vein. In an exemplary embodiment, the lamina cribosa is repeatedly punctured to strip/locally disrupt connective tissue surrounding the central retinal vein.
