1. A device for drilling a tunnel in a bone and forming expansion regions in the-tunnel having a given lateral dimension, comprising:
- an elongate body having an axis;
a head mounted at a distal end of the body;
a sleeve including an inner lumen adapted to accommodate the body with the head protruding from a distal end of the sleeve and adapted to fit through the tunnel; and
characterized by having two operational modes, a tunnel drilling mode in which the sleeve and the head are concentric and a reaming mode in which the sleeve and the head are eccentric;
wherein the drilling mode is suitable for drilling a tunnel in a bone and the reaming mode is suitable for forming expansion regions in a tunnel.

Abstract
A device for forming expansion regions in a bone, comprising, an elongate body having and axis and adapted to fit through a tunnel in a bone; and a head, provided on said body and having outer dimensions not substantially extending trans-axially to said body, wherein said head is rotatable and wherein said head is adapted to widen said tunnel in said bone by at least 10% in conjunction with said rotating.

32. A head adapted for drilling a tunnel and for widening an existing tunnel, comprising:
-
(a) at least one drill cutting edge arranged for cutting bone in a forward pointing direction; and
(b) at least one bone cutting edge arranged for cutting the bone transverse to the forward pointing direction and arranged in a general axial direction;
wherein the head can be set in a first configuration and a second configuration;
wherein the first configuration positions the head so that the bone cutting edge does not cut transverse to the forward pointing direction; and
wherein the second configuration positions the head so that the bone cutting edge cuts transverse to the forward pointing direction. - View Dependent Claims (33, 34, 35)

36. A method of fixating soft tissue to bone, comprising:
-
(a) forming a tunnel in said bone;
(b) forming a radial expansion region in an inner segment of said tunnel;
(c) inserting soft tissue into said expansion region via said tunnel; and
(d) employing a fixation material capable of setting to fixate said soft tissue in said expansion region of said tunnel. - View Dependent Claims (37, 52, 62, 82, 83, 84, 85)
