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.
Claims17
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 coupled 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;
- 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,
- wherein the cannula includes a connector and the delivery gun includes a hub with corresponding features that engage to couple the cannula to the delivery gun, and
- wherein the corresponding features include at least one track and at least one follower sized to fit within and ride along the track, one of the connector and the hub includes the at least one track, and the other of the connector and the hub includes the at least one follower, a first portion of the at least one track extending into the one of the connector and the hub along a first direction, and a second portion of the at least one track extending into the one of the connector and the hub within a plane that is normal to the first direction.

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 coupled 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;
- 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,
- wherein the delivery gun includes a trigger, a first circumferential engagement mechanism, and a second circumferential engagement mechanism, and
- wherein when the trigger is engaged the first circumferential engagement mechanism advances the flexible plunger within the first lumen toward the distal end, and when the trigger is disengaged the second circumferential engagement mechanism prevents movement of the flexible plunger toward the proximal end.

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 coupled 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;
- 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 deflector coupled to the proximal end of the delivery gun, the deflector positioned so as to deflect a portion of the flexible plunger that extends proximally from the proximal end away from the longitudinal axis.

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 coupled 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;
- 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 sled having an elongate body, the elongate body defining a channel extending through the sled, wherein the elongate body of the sled includes a collar extending away from the channel, the elongate body of the sled defining a collar track that extends into the collar toward the channel along a non-linear path;
- 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, wherein the elongate body of the push rod includes a handle extending from the rod portion, the handle including a projection shaped to follow the non-linear path of the collar track.
4 more elements
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.
