APPARATUS FOR TISSUE RESECTION

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 embodiment 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.
