1. A bone graft delivery system, comprising:
- an elongate tube;
a handle engaged to a proximal end of the tube, the handle comprising;
a trigger configured to be actuated to deliver bone graft material through the tube; and
a handle body having a lumen extending from a proximal end of the handle body to a distal end of the handle body, the distal end of the handle body being engaged with a proximal end of the elongate tube such that the lumen of the handle body is aligned with the elongate tube, wherein the handle body comprises a curved surface substantially parallel to a longitudinal axis of the lumen, the curved surface and the trigger configured to be gripped by a hand of the user when the hand of the user is wrapped around the handle body, wherein the lumen is positioned between the curved surface and the trigger; and
a plunger configured to be removably received in the handle and tube while the handle is engaged to the proximal end of the tube.

Abstract
A bone graft delivery system can include an elongate tube, a handle having a trigger, and a tip. The trigger is actuated to deliver bone graft material through the tube. The tip has one or more openings to deliver the bone graft material to a desired location and includes a surface suitable to act as a rasp for decorticating bone. A method for delivering bone graft material to a desired surgical location includes providing a bone graft delivery device, positioning the device adjacent the surgical location, decorticating bone, and delivering bone graft material to the surgical location.

15. A bone graft delivery system, comprising:
-
an elongate tube defining a first lumen section extending from a proximal end of the elongate tube to one or more openings at a distal end of the elongate tube; a handle configured to be actuated to deliver bone graft material through the tube, the handle comprising an outer housing that defines and completely circumferentially surrounds a second lumen section extending along a longitudinal axis of the handle from within the handle to a distal end of the handle, the outer housing comprising a curved gripping surface extending substantially parallel to the longitudinal axis of the handle configured to be held by a hand of a user such that the user'"'"'s hand wraps around the longitudinal axis, wherein the distal end of the handle is engaged to the proximal end of the tube such that the first lumen section and the second lumen section align to define a continuous, completely circumferentially enclosed lumen extending from within the handle to the one or more openings at the distal end of the tube, wherein the first lumen section and the second lumen section are each permanently circumferentially enclosed such that bone graft material is loadable into the lumen only along a longitudinal axis of a portion of the lumen being loaded; a plunger comprising a plurality of notches, the plunger configured to be removably received in the handle and tube while the handle is engaged to the proximal end of the tube; and a tip at the distal end of the elongate tube, the tip comprising; a tip distal end; and the one or more openings at the distal end of the elongate tube, wherein the one or more openings are positioned at least partially proximally and at least partially laterally from the tip distal end, wherein side surfaces of the tip on opposite sides of the longitudinal axis of the lumen taper medially and distally to the tip distal end. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
