摘要： 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. The engagement surfaces are capable of highly localized modulation of Rf energy application to engaged tissue to provide high and low temperatures, voltage and current in the tissue to create high strength welds.

摘要： A working end of a surgical instrument that carries first and second jaws for delivering energy to tissue. In a preferred embodiment, at least one jaw of the working end defines a tissue-engagement plane that contacts the targeted tissue. The cross-section of the engagement plane reveals that it defines a surface conductive portion that overlies a variably resistive matrix of a temperature-sensitive resistive material or a pressure-sensitive resistive material. An interior of the jaw carries a conductive material or electrode that is coupled to an Rf source and controller. In an exemplary embodiment, the variably resistive matrix can comprise a positive temperature coefficient (PTC) material, such as a ceramic, that is engineered to exhibit a dramatically increasing resistance (i.e., several orders of magnitude) above a specific temperature of the material.

摘要： Apparatus and methods for treating tissue at or near a sphincter provide for transluminal introduction of an energy delivery device. The device includes a tissue compression member to compress target tissue at or near the sphincter. A radiofrequency energy source is coupleable to the delivery device to deliver radiofrequency energy to the target tissue. Energy is delivered to heat the tissue to a desired temperature. The desired temperature is selected to induce an injury-healing response or to inducing shrinkage of collagen fibers in the target tissue to thereby reduce laxity in the target tissue.

摘要： 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.

摘要： 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.

摘要： A bone cement injector used for treating vertebral compression fractures has diamond-like coatings or amorphous carbon based coatings with a high hardness and a low coefficient of friction on an interior flow channel thereof. Such a bone cement injector includes a sensor system for sensing retrograde bone cement flows that can migrate along a fractured path toward a pedicle and risk leakage into the spinal canal. An energy delivery system can be coupled to the injector for applying energy to tissue and/or to bone cement that migrates in a retrograde direction, wherein the energy polymerizes the cement and/or coagulates tissue to inhibit further retrograde cement migration.

摘要： A modular implant device and method for dynamic stabilization of a spine segment that can be implanted in a minimally invasive posterior approach. The implant device has superior and inferior body portions configured for engaging two spaced apart spinous processes to limit extension and, optionally, flexion while off-loading a spine segment. The implant device can stabilize a spine segment, re-distribute loads with the spine segment and still allow spine lateral bending and torsion. Implantation of the device is reversible and adjustable post-implantation.
