First Claim
1. An apparatus comprising:
- a head, the head being rotatable about a first axis and configured to effectuate a medical procedure;
a pushrod attached at a distal end to the head and configured to translate along a second axis substantially perpendicular to the first axis, where translation of the pushrod along the second axis rotates the head about the first axis;
a handle attached to the proximal end of the pushrod, the handle including;
a base, a lever coupled at a rotation point on a first end thereof to the base and rotatable at the rotation point about a third axis substantially perpendicular to the second axis, where the lever is coupled at the first end to the pushrod and pivoting the lever about the third axis translates the pushrod along the second axis; and
a locking mechanism configured to lock the lever into one or more locked positions, where each locked position of the lever corresponds to a locked position of the head.

Abstract
A method and apparatus for creating or enlarging a cavity in a patient'"'"'s body are provided. One implementation of the apparatus includes a head, a pushrod and a handle. The head is rotatable about a first axis and is configured to effectuate a medical procedure. The pushrod is attached at a distal end to the head and attached at a proximal end to a handle. The pushrod is configured to translate along a second axis substantially perpendicular to the first axis, where translation of the pushrod along the second axis rotates the head about the first axis. The handle includes a lever coupled at one first end to the pushrod and pivoting the lever about the third axis translates the pushrod along the second axis.

11. An apparatus comprising:
-
a head including one or more cutting portions and attached at a proximal end to a pushrod;
the pushrod attached at a proximal end to a handle, the pushrod configured to translate along a first axis, where translation of the pushrod along the first axis translates the head along the first axis;
the handle including;
a base, a lever coupled at a rotation point on a first end thereof to the base and rotatable at the rotation point about a second axis substantially perpendicular to the first axis, where the lever is coupled at the first end to the pushrod and pivoting the lever about the second axis translates the pushrod along the first axis; and
a locking mechanism configured to lock the lever into one or more locked positions, where each locked position of the lever corresponds to a locked position of the head. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method comprising:
-
establishing an access path to a location in a patient'"'"'s body;
introducing a head of a medical device through the access path to the location, the medical device comprising;
the head, the head being rotatable about a first axis and configured to effectuate a medical procedure;
a pushrod attached at a distal end to the head and attached at a proximal end to a handle, the pushrod configured to translate along a second axis substantially perpendicular to the first axis, where translation of the pushrod along the second axis rotates the head about the first axis;
the handle including;
a base, a lever coupled at a rotation point on a first end thereof to the base and rotatable at the rotation point about a third axis substantially perpendicular to the second axis, where the lever is coupled at the first end to the pushrod and pivoting the lever about the third axis translates the pushrod along the second axis; and
a locking mechanism configured to lock the lever into one or more locked positions, where each locked position of the lever corresponds to a locked position of the head; and
pivoting the lever about the third axis to translate the pushrod along the second axis thereby rotating the head about the first axis from an initial position substantially collinear to the pushrod to an expanded position non-collinear to the pushrod. - View Dependent Claims (19, 20, 21, 22)
