INTERBODY IMPLANTS AND GRAFT DELIVERY SYSTEMS

摘要

According to some embodiments, a method for promoting spinal fusion using a spinal implant comprises providing a spinal implant, wherein the spinal implant comprises at least one internal chamber being is adapted to receive at least one graft and/or other fill material. In some arrangements, one or more walls of the spinal implant comprise at least one opening or hole that places the internal chamber in fluid communication with an exterior area or portion of the spinal implant. The method additionally includes positioning the spinal implant between two adjacent vertebrae of a patient and directing at least one graft and/or other fill material into the internal chamber of the spinal implant through the access port.

主权项

1. A spinal implant configured for placement within an intervertebral space of a subject, comprising:
a distal end and a proximal end, the distal end being configured to be placed within the intervertebral space using a TLIF approach; a medial wall and a lateral wall generally opposite of the medial wall, wherein the medial and lateral walls extend from the distal end to the proximal end of the implant, wherein at least one of the medial wall and the lateral wall comprises at least one opening; at least one chamber defined by the distal and proximal walls and the medial and lateral walls, the at least one chamber being in fluid communication with the at least one opening of the medial wall or the lateral wall; an access port along the proximal end of the implant, wherein the access port is configured to secure to a insertion tool, the access port being in fluid communication with the at least one chamber of the implant; wherein the at least one opening along the medial or lateral wall is angled relative to the longitudinal axis of the spinal implant by an angle θ, wherein θ is approximately 10-45 degrees.
