Abstract:
1. A method of accessing and anchoring tissue in a patient which corresponds to a lesion site within the patient's body comprising: a) locating the approximate position of tissue which corresponds to a lesion site within the patient's body by detecting radiation from a radioactive material accumulated within the tissue corresponding to the lesion site with a radiation detector; and b) accessing the tissue corresponding to the lesion site with an accessing and anchoring device having an elongated shaft having a distal end with a transverse dimension, a proximal end, a longitudinal axis, at least one radially extending anchoring element, and a tissue cutting member at the distal end of the shaft having a transverse dimension greater than the transverse dimension of the distal end by activating the tissue cutting member to ablate tissue to facilitate passing the shaft into the patient's body through tissue until the distal end of the shaft is disposed adjacent the tissue corresponding to the lesion site; c) extending at least one anchoring element from the shaft and into the tissue corresponding to the lesion site; and d) securing the distal end of the device to the tissue corresponding to the lesion site.
