ABSTRACT:
According to an aspect of the present invention, a medical device is provided, which comprises the following: (a) a hollow elongate body (e.g., a elongate cylinder, such as a needle) having distal and proximal ends; and (b) a rotatable member comprising a tissue morselizer and an elongate shaft (e.g., an auger-like tissue-drilling bit). The device (i) advances material (e.g., morselated tissue) toward the proximal end of the hollow elongate body when the shaft is rotated in a first direction, and (ii) advances material (e.g., a therapeutic agent and/or a bulking agent) toward the distal end of the hollow elongate body when the shaft is rotated in a second direction that is opposite the first direction. The invention also provides a method of treatment for morselizing and removing tissue from within the patient and creating a void within the patient and introducing a therapeutic agent and/or a bulking agent into the void.
