1. A method of fixing a graft in a selected region of an anatomy with an anchor member, comprising:
- connecting the graft to a graft connection region of the anchor member, wherein the anchor member includes a body extending from a first end to a second end and having a maximum exterior dimension transverse to a first axis between the first end and the second end, a lever arm is connected with the body near the first end of the body, and the graft connection region spaced a distance from the first end, 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;
forming a bore in the anatomy having an internal dimension where the at least one dimension of the graft connection region is less than the internal dimension of the bore to allow the graft to be moved through and positioned relative to the bore without substantially binding the graft in the bore;
holding the lever arm relative to the body with a holding mechanism in a non-activated position such that the lever arm is maintained to allow the anchor member to pass through the formed bore;
moving the anchor member through the formed bore in the anatomy with the lever arm held with the holding mechanism in the non-activated position; and
moving the lever arm around an axis of motion substantially at an end of the lever arm to an activated position such that a portion of a single end of the lever arm extends beyond the maximum exterior dimension to engage a selected portion of the anatomy;
wherein the lever arm is configured to contact a stop portion to limit rotation of the lever arm around the axis.

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.

7. A method of fixing a graft in a selected region of an anatomy with an anchor member, comprising:
-
connecting the graft to a graft connection region of the anchor member, wherein the anchor member includes a body extending along a central longitudinal axis from a first end to a second end and having a maximum exterior dimension transverse to a first axis between the first end and the second end, a lever arm is connected with the body near the first end of the body, and the graft connection region defined by 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; forming a bore in the anatomy having an internal dimension where the at least one dimension of the graft connection region is less than the internal dimension of the bore to allow the graft to be moved through and positioned relative to the bore without substantially binding the graft in the bore; holding the lever arm relative to the body with at least a portion of an elongated holding member in a non-activated position such that the lever arm is maintained substantially within the maximum exterior dimension to allow the anchor member to pass into the formed bore by positioning the elongated holding member between the lever arm and the body; moving the anchor member into the formed bore in the anatomy using the elongated holding member and with the lever arm held with the elongated holding member in the non-activated position; and moving the lever arm around an axis of motion substantially at an end of the lever arm to an activated position, limiting movement of the lever arm with a stop portion, such that a single end portion of the lever arm extends beyond the maximum exterior dimension to engage a selected portion of the anatomy. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A method of fixing a graft in a selected region of an anatomy with an anchor member, comprising:
-
connecting the graft to a graft connection region of the anchor member, wherein the anchor member includes a body extending from a first end to a second end along a body axis, a lever arm connected with the body near the first end of the body and able to rotate around a lever arm pin, and the graft connection region spaced a distance from the first end, wherein the graft connection region has at least one graft connection dimension that is transverse to the body axis and less than at least one maximum exterior dimension of the body; forming a bore in a femur of the anatomy having an internal dimension where at least one graft connection dimension of the graft connection region is less than the internal dimension of the bore to allow the graft to be moved through and positioned relative to the bore without substantially binding the graft in the bore; holding the lever arm relative to the body with at least a portion of an elongated holding member in a non-activated position such that the lever arm is maintained substantially within the at least one maximum exterior dimension of the body to allow the anchor member to pass into the formed bore; moving the anchor member into the formed bore in the femur using the elongated holding member and with the lever arm held with the elongated holding member in the non-activated position; and moving the lever arm around the lever arm pin that is substantially at a first end of the lever arm until the lever arm contacts a stop portion of the anchor member to resist rotation of the lever arm such that a single second end portion of the lever arm extends beyond the at least one maximum exterior dimension of the body in an activated position to engage a selected portion of the anatomy. - View Dependent Claims (17, 18, 19, 20, 21, 22)
