Abstract

A radially ported bone graft needle, particularly useful in minimally invasive procedures, is provided. The bone graft needle delivers bone graft material to a bone defect area by extruding the bone graft material both axially and radially simultaneously.

Claims

1. A bone graft needle for delivery of bone graft material to a bone defect area in a patient'"'"'s body comprising

an elongate tubular delivery member having an open distal end for positioning at the bone defect area via a minimally invasive portal providing access to the bone defect area from externally of the patient'"'"'s body and having an open proximal end for being supplied with bone graft material from externally of the patient'"'"'s body, said open distal end being aligned with a central longitudinal axis of said delivery member for discharge of the bone graft material therefrom in an axial direction at the bone defect area, said delivery member comprising at least one radial port spaced proximally from said open distal end for discharge of the bone graft material therefrom in a radial direction at the bone defect area.

2. A method of delivering a bone graft material to a bone defect area in a patient'"'"'s body comprising the steps of

introducing an open distal end of a bone graft needle at a bone defect area in the patient'"'"'s body through a minimally invasive portal with the bone graft needle extending externally of the patient'"'"'s body;

supplying bone graft material to a passage through the bone graft needle communicating with the open distal end and with a radial port of the bone graft needle;

pressurizing the bone graft material within the passage;

is charging the bone graft material from the passage to the bone defect area in an axial direction through the open distal end and in a radial direction through the radial port; and

withdrawing the bone graft needle from the patient'"'"'s body through the portal.
