  • Patent number: 10278754
    Abstract: Systems and methods for treating bone, such as vertebral compression fractures are disclosed. A method includes controllably applying energy to a bone cement volume outside of a patient's body to selectively accelerate the polymerization rate of the bone fill material volume prior to introduction into a bone. The method further includes sequentially introducing a plurality of cement carrying structures with the accelerated polymerization rate bone cement volume into the bone. A system for use in the method includes at least one elongated cement-carrying structure sized to carry a bone cement volume therein and an energy source operatively coupleable to the cement-carrying structure. The energy source applies energy to the bone cement volume to selectively accelerate a polymerization rate thereof. An elongated injector insertable into the bone has a passageway that removably receives the elongated cement-carrying structure to allow delivery of the accelerated polymerization rate bone cement into the bone.

  • Publication number: 20180147003
    Abstract: An electrosurgical device comprises an elongated shaft having an axis with an interior channel extending along the axis to an opening in a distal end of the shaft. The channel is configured to be coupled to a negative pressure source, and an electrode with a conductive, usually hook-shaped, distal portion is coupled to the shaft and moveable between a first position in which a distal tip of the electrode is disposed proximate to a periphery of the opening of and a second position in which the distal electrode tip is exposed and spaced apart from the opening.

  • Patent number: 9821085
    Abstract: The present disclosure relates to bone cement formulations that have an extended working time for use in vertebroplasty procedures and other osteoplasty procedures together with cement injectors that include energy delivery systems for on-demand control of cement viscosity and flow parameters. The bone cement formulations may include a liquid component having at least one monomer and a non-liquid component including polymer particles and benzoyl peroxide (BPO). The non-liquid component may be further configured to allow controlled exposure of the BPO to the liquid monomer so as to enable control of the viscosity of the bone cement composition.

  • Patent number: 8562620
    Abstract: Systems, bone cements and methods for treating vertebral compression fractures can utilize a bone cement comprising of a mixable liquid monomer component and a non-liquid component including polymer particles, wherein the non-liquid component is configured for controlled exposure to the liquid monomer over a setting interval of the bone cement. In a method of use, liquid and non-liquid components are mixed, and the bone cement is injected into bone wherein a lengthened setting interval is provided in which the mixture is configured for a flowability that prevents unwanted extravasation.

  • Publication number: 20120271300
    Abstract: An instrument for thermally-mediated therapies in targeted tissue volumes or for volumetric removal of tissue. In one embodiment, the instrument has an interior chamber that includes a diffuser structure for diffusing a biocompatible conductive fluid that is introduced under high pressure. The interior chamber further includes surfaces of opposing polarity electrodes for vaporizing the small cross-section diffused fluid flows created within a diffuser structure. In one embodiment, the diffuser structure includes a negative temperature coefficient of resistance material between the opposing polarity surfaces. The NTCR structure can self-adjust the lengths of current paths between the opposing polarities to insure complete vaporization of the volume of flow of conductive fluid.

  • Patent number: 8075558
    Abstract: An electrosurgical working end and method for sealing and transecting tissue. An exemplary working end provides curved jaw members that are positioned on opposing sides of the targeted anatomic structure. The working end carries a slidable extension member having flange portions with inner surfaces that slide over the jaw members to clamp tissue therebetween. The working end carries an independent slidable cutting member that is flexible to follow the curved axis of the jaws. The electrosurgical surfaces of the jaws include partially-resistive bodies for carrying a current or load which modulates ohmic heating in the engaged tissue to prevent charring and desiccation of tissue to create a high strength thermal seal.

  • Publication number: 20110004208
    Abstract: Various embodiments provide an electrosurgical instrument with a disposable electrosurgical cartridge. In one embodiment, the cartridge has first and second energy-delivery surfaces that carry first and second opposing polarity conductors coupled to a voltage source, together with first and second temperature-responsive variable impedance bodies exposed partly in the respective-delivery surfaces. The cartridge further carries a slidable blade member. The temperature-responsive variable impedance bodies are coupled to the voltage source by series and parallel circuitry. In use, the variable impedance bodies are adapted to modulate current flow and ohmic heating in engaged tissue by providing controlled current paths in the tissue and through the variable impedance bodies as the temperature-responsive bodies sense the temperature of adjacent engaged tissue.
