A device for cutting and damaging a tissue specimen in surrounding tissue comprises an elongated wand with a proximal end and a distal end, means at the distal end for inserting the wand into tissue, an operational portion at a distal portion of the wand, a tissue cutting tool which is disposed at the operational portion configured to at least partially isolate a desired tissue specimen from surrounding tissue at the tissue site adjacent to the operational portion by cutting at least a partial peripheral channel about the tissue specimen, and having a tissue specimen damager, disposed within the operational portion to damage the isolated tissue specimen in order to necrotize the severed tissue specimen, wherein the tissue specimen damager comprises
a. a plurality of outlets that permit the flow of a chemical into the isolated tissue specimen in order to necrotize the isolated severed tissue specimen; or
b. an ionizing radiation director; or
c. a thermal damaging means selected from the group consisting of a laser device, means to deliver hot fluid, means to delivery cryogenic fluid, means to deliver radio frequency energy, means to deliver focused ultrasound, means to delivery mechanical ultrasound, means to deliver shock waves and means to deliver a heated object; or
d. a means to morcellate tissue of the isolated tissue specimen; or
e. a plurality of tissue damaging elements. |
