Abstract
Provided herein are bone graft delivery systems comprising a flexible plunger, a delivery gun, and a detachable offset cannula. Methods of delivering bone graft material using the bone graft delivery systems are also provided.
Claims19
A bone graft delivery system comprising:
- a delivery gun comprising a proximal end, a distal end, and a body extending therebetween, the body defining a first lumen extending through the body from the proximal end to the distal end along a longitudinal axis;
- a cannula couplable to the distal end of the delivery gun, the cannula defining a second lumen extending through the cannula along a first portion that is aligned with the longitudinal axis, and a second portion that is angularly offset from the longitudinal axis, wherein the cannula is couplable to the delivery gun in a plurality of orientations;
- and
- a flexible plunger sized to be insertable into the first lumen through an opening defined by the proximal end, and the flexible plunger is movable to a position wherein a distal portion of the flexible plunger is within the second portion of the second lumen and a proximal portion of the flexible plunger is within the first lumen.

A method of delivering bone graft material, the method comprising:
- loading a bone graft material into a channel of a sled;
- inserting the sled into a lumen of a cannula such that the bone graft material is positioned within the lumen of the cannula;
- moving a push rod into and along the channel thereby pushing the bone graft material out of the channel and loading the bone graft material into the lumen of the cannula;
- inserting a follower coupled to the push rod into a track defined by the sled;
- moving the follower along a non-linear path defined by the track;
- exerting a force on a handle of the push rod thereby simultaneously removing the push rod and the sled from the lumen of the cannula without removing the push rod from the channel of the sled;
- attaching the cannula with the bone graft material inside the lumen to a distal end of a delivery gun;
- moving a distal tip of a flexible plunger through an opening formed in a proximal end of the delivery gun;
- moving the distal tip of the flexible plunger through a lumen of the delivery gun, toward the distal end of the delivery gun, along a longitudinal axis of the delivery gun;
- moving the distal tip of the flexible plunger through the distal end and into the lumen of the cannula;
- moving the distal tip through a first portion of the cannula along the longitudinal axis;
- moving the distal tip through a second portion of the cannula along a direction that is angularly offset from the longitudinal axis;
- and
- pushing the loaded graft material out of the lumen of the cannula with the distal tip of the flexible plunger.

A bone graft loader comprising:
- a sled having an elongate body, the elongate body including a tubular member defining a channel extending therethrough, the elongate body further including a collar extending from the tubular member, the collar defining a collar track extending into the collar toward the tubular member, the collar track including a non-linear portion;
- and
- a push rod having an elongate body with a rod portion shaped to correspond to the channel such that the rod portion is slidable within the channel, the elongate body of the push rod further including a handle extending from the rod portion, and a projection shaped to follow the non-linear portion of the collar track.
