Abstract:
1. A tissue cutting device comprising: an elongate shaft having a proximal portion, a distal portion and a lumen defined therein, wherein the distal portion includes an opening for receiving tissue; wherein the distal portion 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, wherein the manipulated distal portion is 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, 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 can access a variety of anatomical locations during a procedure; a cutting mechanism positioned within the distal portion of the elongate shaft, wherein the cutting mechanism is configured to be actuated within the distal portion of the elongate shaft and past the opening to cut tissue in the opening, and wherein manipulation of the distal portion causes manipulation of the cutting mechanism and the opening; and a chamber coupled to the proximal portion of the elongate shaft, the chamber having a cutting mechanism driver assembly positioned therein.
