  • Patent number: 10179068
    Abstract: A surgical hand piece has a connecting body having first and second passages detachably connected to first and second lumens which are used in the eye for phacoemulsification procedures and/or cleanup of the eye capsule after the procedure. The lumens receive or discharge fluid from first and second fluid sources. A work tip supporting the first and second tubes can be rotated so as to change the function of the first and second tubes from aspiration to irrigation and vice versa. As an alternative, a sleeve holding the fluid sources can be rotated so as to change the function of the first and second tubes from aspiration to irrigation and vice versa.

  • Patent number: 10010340
    Abstract: An apparatus comprises a body, an ultrasonic transducer assembly, a shaft assembly, and a coupling assembly. The shaft assembly comprises an acoustic waveguide that is operable to selectively couple with the ultrasonic transducer assembly. The coupling assembly is operable to selectively transition between a first mode and a second mode. The acoustic waveguide is configured to rotate with the transducer assembly relative to the body when the coupling assembly is in the first mode. The acoustic waveguide is configured to rotate relative to the transducer assembly and relative to the body when the coupling assembly is in the second mode. The coupling assembly is further configured to prevent the transducer assembly from rotating relative to the body when the coupling assembly is in the second mode. The shaft assembly and the end effector are also together configured to transition between an operational mode and a cleaning mode.

  • Patent number: 10010447
    Abstract: A retinal treatment system for delivering therapeutic agents to a target location with a retina is disclosed herein. The retinal treatment system includes a console having a control system and a handheld device coupled to the control system. The handheld device includes an inner tube disposed within an outer tube and being axially moveable within the outer tube. The inner tube has a perforating tip that is configured to perforate an inner limiting membrane of the retina. The handheld device further includes a chamber coupled to a proximal end of the inner tube that is configured to receive a fluid containing therapeutic agents injectable from the perforating tip. The control system of the retinal treatment system permits a user to maintain a position of the handheld device relative to the retina and activate an injection of a portion of the fluid through the inner tube into the retina.

  • Patent number: 10004527
    Abstract: An apparatus comprises a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm comprises a clamp pad. The clamp arm is movable toward the ultrasonic blade to compress tissue between the clamp pad and the ultrasonic blade in two stages. During the first stage, the clamp arm is configured to compress tissue with only a distal portion of the clamp pad. During the second stage, the clamp arm is configured to compress tissue with the distal portion and a proximal portion of the clamp pad. Thus, the tissue compression begins at the distal portion and subsequently progresses toward the proximal portion.

  • Patent number: 9999709
    Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

  • Patent number: 9999466
    Abstract: Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool.
