    摘要： A medical for removing tissue from a patient includes an elongated probe with a working end. A pair of jaws is provided at the working end. The jaws may be closed for cutting and treatment of the tissue. Cutting may be effective through a sharpened cutting blade, and RF cutting blade, and similar cutting edges. The tissue may be remodeled using heat generated from passive heating elements on the jaws, active heating elements on the jaws, a PTCR heating element carried by the jaws, or resistive heaters on the jaws.

    摘要： Systems and methods for delivering bone cement into a bone can include a handle body defining a flow path, a thermal emitter in the handle body to apply energy to bone cement passing through the flow path, a source of bone cement and an injection cannula. The cannula can be in communication with the flow path such that inserting the cannula into a bone can allow a flow of bone cement therethrough to an opening at a distal end of the cannula. Other systems and methods for delivering bone cement into a bone can include an injector body with a handle portion, and a cannula, a bone cement container, a low pressure drive mechanism configured to effect a flow of bone cement from said container to the injector body and a high pressure drive mechanism configured to effect a flow of bone cement through the injector body into the bone.

    摘要： Embodiments of the invention provide an electrosurgical jaw structure comprising first and second opposing jaws one or both of which include 3D variable resistance bodies. The jaw structure can be part of the working end of a surgical instrument. In one embodiment, the jaws can comprise first and second energy-delivery jaw surfaces having first and second 3D variable resistance bodies, with the jaw surface configured to be coupled to an Rf source. The 3D variable resistance bodies can define different temperature-resistance curves. The 3D bodies can be configured to control ohmic heating of tissue by modulating the delivery of Rf energy to tissue. Jaw structures having the 3D bodies can be used to engage and produce high strength tissue welds in targeted tissue including tissue volumes having varying tissue types. Such jaw structures can be configured to simultaneously apply different energy levels to each tissue type within the tissue volume.

    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： An orthopedic implant comprising a deformable, expandable implant body configured for treating abnormalities in bones, such as compression fractures of vertebra, necrosis of femurs and the like. An exemplary implant body comprises a small cross-section threaded element that is introduced into a bone region and thereafter is expanded into a larger cross-section, monolithic assembly to provide a bone support. In one embodiment, the implant body is at least partly fabricated of a magnesium alloy that is biodegradable to allow for later tissue ingrowth.
