  • Patent number: 10912571
    Abstract: A smooth mating surface model defining a mating surface of a customized arthroplasty jig is generated. For example, sagittal slices of a volumetric image of a patient bone are segmented with segmentation splines. An anatomically accurate model of the patient bone is generated from the segmentation splines. The anatomically accurate model includes anatomically accurate segmentation splines. The anatomically accurate segmentation splines are transformed into mating surface contours. Any inadequate segments of the mating surface contours are modified to obtain modified mating surface contours. A mating surface model of the patient bone is generated based on the mating surface contours and the modified mating surface contours. Three-dimensional cross-sections of the mating surface model are smoothed to generate the smooth mating surface model.

    Abstract: A surgical instrument including housing having a shaft extending distally therefrom, an outer sleeve disposed about the shaft and selectively translatable relative to the shaft, a first drive shaft disposed within the shaft and translatable relative to the shaft independently of the outer sleeve, a second drive shaft disposed within the first drive shaft and coupled to the outer sleeve to translate in conjunction with the outer sleeve, and a rotatable nose wheel. The rotatable nose wheel is mounted about a distal end of the housing and is rotatably coupled to each of the outer sleeve, the shaft, the first drive shaft, and the second drive shaft such that rotation of the rotatable nose wheel effects corresponding rotation of the outer sleeve, the shaft, the first drive shaft, and the second drive shaft in conjunction with one another and relative to the housing.

  • Patent number: 10912602
    Abstract: An electrosurgical device can be delivered to a tissue site to provide supplemental sealing of vessels and/or vascular tissue that include suturing, stapling, or the like. The electrosurgical device is generally in the form of forceps, and includes an end effector assembly including opposing movable jaws. Each jaw includes a deformable pad or cushion including an electrode array positioned thereon. Each deformable cushion is configured to deliver a fluid, such as saline, during activation of the electrode array, thereby creating a virtual electrode which couples radiofrequency (RF) energy emitted from the electrode array into tissue in which the RF energy is converted into thermal energy. The deformable cushion and electrode array provide a controlled degree of compression upon the target tissue or vessel to maintain integrity of a suture, staple, or clip, as well as controlled energy emission for sealing, cauterizing, coagulating, and/or desiccating the target tissue or vessel.

  • Patent number: 10912603
    Abstract: A surgical instrument including a handle assembly and an end effector, including a first jaw pivotably coupled to a second jaw, is disclosed. The handle assembly may comprise a jaw position sensor comprising a switch, a closure trigger, and a clamp spring actuatable by the closure trigger. The closure trigger may be configured to: rotate between a first position and a second position, wherein the first position corresponds to the first and second jaws in an open position and the second position corresponds to the first and second jaws in a closed position, and activate the switch of the jaw position sensor at a predetermined rotated position. The clamp spring may be configured to: cause the first and second jaws to transition between the open position and the closed position, and apply a force to the first and second jaws.

  • Patent number: 10912606
    Abstract: Systems and methods for endometrial ablation. The systems include a handle and elongated introducer sleeve extending to an expandable working end having a fluid-tight interior chamber. A thin dielectric wall surrounds at least a portion of the interior chamber and has an external surface for contacting endometrial tissue. The thin dielectric wall surrounds a collapsible-expandable frame and receives an electrically non-conductive gas. First and second polarity electrodes are exposed to the interior and exterior of the chamber, respectively. A radiofrequency power source operatively connects to the electrode arrangement to apply a radiofrequency voltage across the first and second electrodes, wherein the voltage is sufficient to initiate ionization of the neutral gas into a conductive plasma within the interior chamber, and to capacitively couple the current in the plasma across the thin dielectric wall to ablate endometrial tissue engaged by the external surface of the dielectric structure.

  • Patent number: 10912607
    Abstract: The invention relates to an ablation catheter which controls the temperature and reduces the coagulation of biological fluids on an electrode of a catheter, prevents the impedance rise of tissue in contact with the electrode, and maximizes the potential energy transfer to the tissue, thereby allowing an increase in the lesion size produced by the ablation. The electrode includes passages positioned to allow saline flow out of an inner cavity of the electrode. This fluid flow is pulsatile to increase turbulence, reducing areas of stagnant flow, and produces a desired cooling effect.

  • Patent number: 10912608
    Abstract: A device is designed to remove blockages in a lumen such as a thrombus, blood clot, or embolus. The device comprises a manipulating wire and a structure that can conduct electrical current to a lumen blockage. The electrical current is preferably in radio frequency (RF). The RF electric current in the blockage can excite the contents such as proteins of the blockage, so that cross-linking density and interfacial adsorption of the entire blockage is enhanced. The enhanced cross-linking density can result in increased fracture resistance of the blockage such that fracture of the blockage during the removal process is unlikely. The enhanced interfacial adsorption results in increased interfacial fracture resistance between the device and blockage so that the blockage can be securely captured during the removal process without using radially applied force.

    Abstract: An aesthetic treatment device uses multiple light sources, lasers or LEDs focused on the treatment area from different directions. The multiple light sources for treatment purposes could have the same wavelength or different wavelengths each optimized for a different application. Target selection is performed by a dual wavelength smart illumination system combined with an imaging system, a smart processor for target recognition and a scanning system that directs the focused light from laser sources to an automatically selected treatment area. A motorized optical system performs a dual role of: focusing the laser sources and also steering the focused light to specific locations as designated by the imaging and processing systems.
