    摘要: The present invention relates to the field of electrosurgery, and more particularly to a system that produces a focused plasma for tissue ablation. The system includes a probe and a remote source of a conductive liquid media for providing a flow through the probe that functions as an electrode. A pressurized flow of the liquid media passes through a first larger diameter flow channel in the probe to then increases in velocity as it passes through a smaller diameter flow restriction channel in a working end surface. The flow restriction of the liquid electrode through the flow restriction channel when coupled with high frequency voltage causes instantaneous ignition of a plasma within media flow media within the flow restriction channel. The working end surface thus carries a plasma that when proximate to tissue will cause a controlled, focused ablation.

    摘要: An electrosurgical working end for automatic modulation of active Rf density in a targeted tissue volume. The working end of the probe of the present invention defines a tissue-engagement surface of an elastomeric material with conductive elements that extend therethrough. In one embodiment, the expansion of the elastomeric material can de-couple the conductive elements from an interior electrode based temperature to modulate current flow. In another embodiment, the elastomeric material can couple and de-couple the conductive elements from an interior electrode based on engagement pressure to modulate current flow

    摘要: An apparatus and method for distraction of tissue or bone in a surgery. A method comprises inserting into targeted tissue a distraction device configured with at least one phase transition extendable body. After deployment in a non-extended configuration, the physician applies a stimulus to the body or bodies to cause a liquid-to-vapor or solid-to-vapor phase transition within the body that extends the body in a fast event from the non-extended configuration to an extended configuration to thereby apply distraction forces to the targeted tissue. The extendable body is made of biocompatible materials having any suitable configuration. In one embodiment, the implant and system is used for reducing a vertebral compression fracture. The distraction system can be used to distribute forces over a selected region of strong cortical bone to restore vertebral height. Such a system can be dimensioned as a cylindrical, spherical, annular or part-annular construct for creating selected directional forces for moving apart cortical endplates.

    摘要: An electrosurgical medical device and method for creating thermal welds in engaged tissue. In one embodiment, at least one jaw of the instrument defines a tissue engagement plane carrying a conductive-resistive matrix of a conductively-doped non-conductive elastomer. The engagement surface portions thus can be described as a positive temperature coefficient material that has a unique selected decreased electrical conductance at each selected increased temperature thereof over a targeted treatment range. The conductive-resistive matrix can be engineered to bracket a targeted thermal treatment range, for example about 60° C. to 80° C., at which tissue welding can be accomplished. In one mode of operation, the engagement plane will automatically modulate and spatially localize ohmic heating within the engaged tissue from Rf energy application—across micron-scale portions of the engagement surface.

    摘要: The present invention relates in certain embodiments to medical devices for treating osteoplasty procedures such as vertebral compression fractures. More particularly, embodiments of the invention relate to instruments and methods for controllably restoring vertebral body height by controlling the geometry of fill material introduced into cancellous bone. An exemplary system utilizes Rf energy in combination a conductive bone fill material for polymerizing the surface of the inflow plume to control the geometry of the fill material and the application of force caused by inflows of fill material. In another embodiment, method of treating bone includes injecting a volume of fill material into a bone and selectively modifying a viscosity of a selected portion of the bone filler to control the direction of flow of the fill material within the bone. A system for treating bone using this method includes an introducer for delivering fill material into the bone and an energy source selectively coupleable to the fill material to alter the viscosity of the fill material as it flows out of the introducer.
