    摘要: A bipolar electrosurgical scraper device is provided comprising a handle, a blade having a thickness and a beveled distal end with the beveled distal end terminating distally in a scraping edge. The beveled distal end includes a first electrode and a second electrode with the first electrode and the second electrode provided along a width of the blade and spaced apart with respect to the thickness of the blade. The device also comprises a fluid passage at least one fluid outlet in fluid communication with the fluid passage.

    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.
