Claims3
A tool for filling tubes with bone graft material comprising:
- (a) a pneumatic cylinder and plunger constructed and arranged to travel within a housing that includes an access port into which bone graft material may be tamped into a channel that the plunger reciprocates within;
- and
- (b) a fill tube attached to said housing and in fluid communication with said channel such that movement of said plunger causes material within said channel to fill said fill tube.
An elongated hollow cylindrical tube of less than about 12 inches (30.5 cm) in length and having an internal bore diameter of between about 0.01″ (0.25 mm) to about 0.03″ (0.76 cm), said tube having a distal end and a proximal end, said distal end including a coupling member for attaching the tube in line within a filling device, said tube being filled with a bone graft material.
