Abstract:
1. A vacuum powered tissue cutting device comprising: an elongate shaft having a proximal portion, a distal portion and a lumen defined therein, wherein the distal portion has an opening for receiving tissue; a cutter positioned within the distal portion of the elongate shaft, wherein the cutter is configured to be actuated within the distal portion of the elongate shaft and past the opening to cut tissue in the opening, wherein the distal portion of the elongate shaft with the cutter positioned therein includes at least a section which is adjustable and is configured to be manipulated into a first configuration by hand without the use of a separate tool prior to inserting the distal portion of the elongate shaft into a patient's body, wherein the elongate shaft is configured to retain the manipulated first configuration of the distal portion and cutter while positioned in the patient's body, and wherein the manipulated distal portion and cutter are configured to be hand adjusted into a second configuration, wherein the elongate shaft is configured to retain the manipulated second configuration of the distal portion and cutter, wherein the at least a section of the distal portion is configured to be manipulated in a range including a straight configuration and a curved configuration in an arc of up to 180 degrees such that the elongate shaft and cutter can access a variety of anatomical locations during a procedure; and a chamber coupled to the proximal end of the elongate shaft, the chamber having a mechanism positioned therein, wherein the mechanism is powered by suction created by a vacuum source such that the mechanism produces an actuating motion which causes the cutter to actuate.
