    摘要： A resection device includes an elongated probe shaft and a tissue resection member disposed at a distal end of the elongated probe shaft. The tissue resection member has a cutting surface configured for being placed in contact with tissue. In one aspect of the invention, at least one ejection port is located adjacent to the cutting surface of the tissue resection member, wherein the at least one ejection port is coupled to a source of a polymerizable hemostasis-promoting material that is delivered to the resection site of interest. In certain embodiments, polymerization of the hemostasis-promoting material may be accelerated by application of heat, radiofrequency energy, or ultra violet light.

    摘要： A method of treating a patient is provided. The method comprises delivering an electrically conductive material within a vascular network, wherein the electrically conductive material embolizes in a region of the vascular network to form a vascular electrode array that assumes a geometry of the embolized region of the vascular network. The method may optionally comprise delivering a containment agent within the vascular network proximal to the delivered electrically conductive material to stabilize the vascular electrode array. The method further comprises applying electrical energy (e.g., radio frequency (RF) energy) to the vascular electrode array to therapeutically conduct electrical energy into a region of the targeted tissue adjacent the embolized region of the vascular network.
