    Abstract: A vitrector for performing a vitrectomy comprises a tubular shaft portion which is attached to a distal end of a vitrector hand piece. The shaft portion is provided with a sharply pointed needle tip portion for piercing the pars plana and sclera of the eye, and a pneumatically driven guillotine cutter is incorporated within the shaft portion of the vitrector at a location immediately adjacent to the sharply pointed needle tip portion. A source of pneumatic air is operatively connected to the proximal end of the vitrector hand piece and is pneumatically connected to the guillotine cutter so as to drive the same. In addition, an aspiration line is also operatively connected to the proximal end of the vitrector hand piece and is also fluidically connected to the region immediately adjacent to the pneumatically driven guillotine cutter so as to remove the floater particles, severed from the vitreous cavity by means of the pneumatically driven guillotine cutter, by means of aspiration.

  • Patent number: 11611307
    Abstract: A short-circuit fault-tolerant control method based on deadbeat current tracking for a five-phase permanent magnet motor with a sinusoidal back-electromotive force or a trapezoidal back-electromotive force (EMF) is provided. By fully utilizing a third harmonic space of a five-phase permanent magnet motor in a fault state, the method proposes a fault-tolerant control strategy for a five-phase permanent magnet motor with a sinusoidal back-EMF or a trapezoidal back-EMF in case of a single-phase short-circuit fault. The method enables the five-phase permanent magnet motor to make full use of the third harmonic space during fault-tolerant operation, thereby improving the torque output of the motor in a fault state and improving the fault-tolerant operation efficiency of the motor. The method achieves desirable fault-tolerant performance and dynamic response of the motor, and expands the speed range of the motor during fault-tolerant operation.

    Abstract: An apparatus for inhibiting tissue migration during a procedure comprises a deployment catheter defining at least one lumen therethrough and a non-inflatable hood projecting distally from the deployment catheter and defining an open area. The open area is in fluid communication with the at least one lumen. The apparatus also comprises a visualization element disposed within or along the non-inflatable hood for visualizing tissue adjacent to the open area. The apparatus also comprises a tissue grasping end effector positioned within the open area and configured to temporarily engage the tissue adjacent to the open area such that distal migration of the tissue relative to the barrier or membrane is inhibited.

  • Patent number: 11369810
    Abstract: An ultrasonic therapy system delivers ultrasonic therapy energy to a therapy site in the body which is infused with microbubbles. A system without an image guidance capability has an array transducer which delivers therapy energy, a therapy transducer driver which causes the array transducer to deliver therapeutic energy, a control for controlling the intensity of the therapeutic energy, and a display of the sonotherapy signal strength of the energy and the concentration of microbubbles at the therapy site. A system with ultrasonic imaging capability will display an ultrasound image for therapeutic guidance and a measure of the microbubble concentration. The method of the present invention is performed as an adjunct to a standard drug therapy or other treatment regimen, following such treatment with an infusion of ultrasound and delivery of ultrasound therapy energy.

  • Patent number: 11350963
    Abstract: An apparatus is configured to provide hemostasis with tissue removal in order to inhibit one or more of blood loss or tissue drainage. In many embodiments, a nozzle releases a liquid jet in a liquid medium in order to provide cavitation and a plurality of shedding pulses. The liquid jet, its cavitation and the plurality of shedding pulses can affect vascular tissue in order to promote clotting in order to inhibit bleeding. In many embodiments, vessels of the vascular tissue are affected at a distance from a region where cavitation of the water jet contacts the tissue. In many embodiments, the cavitation and plurality of shedding pules are related to a pulsatile shear wave propagating along the blood vessel that is related to clot promoting changes of the blood vessel.

  • Patent number: 11344375
    Abstract: Surgical assemblies, instruments, and related methods are disclosed that control tissue gripping force. A method for controlling grip force in a robotic surgical instrument includes actuating an input link of a spring assembly. An actuation force is transferred from the input link to an output link of the spring assembly. Relative movement is inhibited between the input link and the output link when the transferred actuation force is below a predetermined level with a preloaded spring of the spring assembly. The input link is moved relative to the output link by deforming the preloaded spring when the transferred actuation force increases above the predetermined level. A grip mechanism is actuated via the output link.

  • Patent number: 11331135
    Abstract: An energy delivery probe is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the energy can be applied with a vapor media. The energy delivery probe can include a vapor delivery member configured to extend into a transition zone prostate tissue. A condensable vapor media can be delivered from the vapor delivery member into the transition zone tissue, wherein the condensable vapor media can propagate interstitially in the transition zone tissue and be confined in the transition zone tissue by boundary tissue adjacent to the transition zone tissue. Methods associated with use of the energy delivery probe are also covered.

  • Patent number: 11324878
    Abstract: An irrigation system for anal or stomal irrigation includes a tubing system attachable between a reservoir and a catheter. The tubing system has a proximal portion attachable to the reservoir and a distal portion including a distal end that is attachable to the catheter, with the tubing system providing an irrigation flow path from the proximal portion attachable to the reservoir through the distal end attachable to the catheter. A pump is operable to move the liquid through the irrigation flow path to provide the anal or stomal irrigation out of the catheter. A pressure control device is attachable to the distal portion of the tubing system and communicates with the catheter. The pressure control device has a valve that is adapted to limit an irrigation pressure for the anal or stomal irrigation out of the catheter to a value less than a pre-determined pressure threshold.
