1. A method of fixing a member in a selected region of an anatomy with an anchor member, comprising:
- providing the anchor member including;
providing a body extending along a first axis including a first end and a second end and having an exterior dimension;
providing a lever arm interconnected with the body a distance from the first end of the body, movable between an activated position and a non-activated position; and
providing a connection region spaced a distance from the first end towards the second end of the body;
providing a holding mechanism that selectively holds the lever arm relative to the body;
holding the lever arm substantially within the exterior dimension with the holding mechanism;
releasing the lever arm to move relative to the body;
moving the lever arm about an axis of motion substantially at an end of the lever arm to the activated position such that a portion of the lever arm moves from within the exterior dimension to extend beyond the exterior dimension to engage a selected portion of the anatomy; and
contacting a stop portion that extends from the body but is within the exterior dimension;
wherein the body receives a portion of the lever arm in the non-activated position such that the exterior dimension is substantially maintained.

Abstract
An apparatus and method for fixing a selected graft relative to a selected anatomical portion. An anchor may be provided that may be interconnected with a selected graft portion that is operable to pass through a selected bore and then moved into an operable position to engage a selected portion of the bore to substantially eliminate the possibility of the graft moving in an unselected direction through the bore.

6. A method of fixing a member in a selected region of an anatomy with an anchor member, comprising:
-
providing the anchor member; engaging a holding member with the anchor member to assist in maintaining the anchor member in a first configuration, including positioning the holding member between a wall that forms a depression in a body of the anchor member and an exterior wall of a lever arm; moving the anchor member to the selected region of the anatomy at least with assistance of the holding member; disengaging the holding member from the anchor member to configure the anchor member to a second configuration, including removing the holding member from the depression; and engaging the selected region of the anatomy with the anchor member to fix the anchor member in the selected region of the anatomy wherein the anchor member includes the body and the lever arm; rotating the lever arm relative to the body; providing a lever arm stop portion; and engaging a body stop portion with the lever arm stop portion to stop rotation of the lever relative to the body, wherein the body stop portion extends over the depression. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A method of fixing a member in a selected region of an anatomy with an anchor member, comprising:
-
providing the anchor member including; providing a body extending along a first axis including a first end and a second end and an exterior dimension; providing only a single lever arm interconnected with the body near the first end of the body, movable between an activated position and a non-activated position where the single lever arm is in a depression formed by the body; and providing a holding member to selectively interconnect the single lever arm and the body and hold the single lever arm substantially within the exterior dimension; providing an actuating member operably associated with the anchor member; moving the anchor member relative to the selected region of the anatomy with the actuating member; after moving the anchor member, releasing the single lever arm to extend a distance beyond the exterior dimension at least by disconnecting the holding member from the single lever arm; and moving the single lever arm around an axis of rotation positioned substantially at an end of the single lever arm such that a portion of the single lever arm extends beyond the exterior dimension to engage a selected portion of the anatomy; wherein the body receives a portion of the single lever arm such that the single lever arm is substantially maintained within the exterior dimension in the non-activated position. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method of fixing a member in a selected region of an anatomy with an anchor member, comprising:
-
preparing the anchor member including; providing a body extending along a first axis including a first end and a second end and having a maximum exterior dimension transverse to the first axis; providing a lever arm connected with the body a distance from the first end of the body, movable between an activated position and a non-activated position; providing a graft connection region spaced a distance from the first end generally along the first axis towards the second end of the body, wherein the graft connection region has at least one graft connection dimension that is also transverse to the first axis and less than the maximum exterior dimension; and connecting a graft portion with the graft connection region; providing a holding mechanism that selectively holds the lever arm relative to the body; holding the lever arm in the non-activated position substantially within the maximum exterior dimension with the holding mechanism; forming a bore in the anatomy wherein the at least one dimension is less than an internal dimension of the bore formed in the anatomy, wherein the at least one dimension allows for the graft to be moved through and positioned relative to the bore without substantially binding the graft in the bore; releasing the lever arm to move relative to the body; and moving the lever arm around an axis of motion substantially at an end of the lever arm to the activated position such that a single end portion of the lever arm extends beyond the maximum exterior dimension to engage a selected portion of the anatomy; wherein the body receives a portion of the lever arm such that the exterior dimension is substantially maintained in the non-activated position. - View Dependent Claims (22)
