Abstract
A cutting device includes an elongated shaft that extends between a proximal end and a distal end. A distal arm extends from the distal end of the elongated shaft. The distal arm includes an inner surface defining a cavity and an outer surface defining a blunt tip. At least one proximal arm extends from the distal end of the elongated shaft at a position proximal to the distal arm. The at least one proximal arm has an inner surface defining a cavity including a cutting portion configured to cut tissue.

A cutting device comprising:
- an elongated shaft extending between a proximal end and a distal end;
- a distal arm extending from the distal end of the elongated shaft, the distal arm including an inner surface defining a cavity and an outer surface defining a blunt tip;
- and
- at least one proximal arm extending from the distal end of the elongated shaft at a position proximal to the distal arm, the at least one proximal arm having an inner surface defining a cavity including a cutting portion configured to cut tissue.

A device for cutting tissue comprising:
- an elongated shaft extending between a proximal end and a distal end;
- a distal arm extending from the distal end of the elongated shaft, the distal arm including an inner surface defining a cavity and an outer surface defining a blunt tip;
- two proximal arms extending from the distal end of the elongated shaft at a position proximal to the distal arm, each of the proximal arms having an inner surface defining a cavity including a cutting portion configured to cut tissue;
- and
- an attachment to a vacuum disposed at the proximal end of the elongated shaft to produce suction so as to remove tissue from the cavity.

A method of cutting tissue comprising:
- inserting a cannula to form a hole in the tissue;
- inserting a cutting device through the cannula, the cutting device comprising:
- an elongated shaft extending between a proximal end and a distal end;
- a distal arm extending from the distal end of the elongated shaft, the distal arm including an inner surface defining a cavity and an outer surface defining a blunt tip;
- two proximal arms extending from the distal end of the elongated shaft at a position proximal to the distal arm, each of the proximal arms having an inner surface defining a cavity including a cutting portion configured to cut tissue;
- and
- an attachment to a vacuum disposed at the proximal end of the elongated shaft to produce suction to remove tissue from the cavity;
- pulling the cutting device in a proximal direction such that the cutting portion cuts the tissue with a single slice;
- capturing cut tissue with the distal arm and directing the cut tissue into the cavity of the distal arm;
- and
- removing the cutting device and the cannula.
