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.

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： 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： Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool. Thus, over a first cutting portion, radio frequency current may help cut the tissue and over a second or over transition region, the RF current may initiate vaporization of the fluid or other liquid to propel the tissue from the cutting device.

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.
