Percutaneous cage delivery systems devices and methods

摘要

An insertion guide to aid in placing a cage into an intervertebral space is presented. The insertion guide has an elongate insertion member having a cross-sectional shape configured to engage a portion of the cage. An end of the insertion member is positioned in a desired location in the intervertebral space and the cage slides along the length of the insertion member to the desired location.

主权项

1. An intervertebral space insertion system comprising:
a body defining an interior longitudinal channel extending from a proximal opening to a distal opening; a guide wire having a distal end, a longitudinal length and a cross-sectional profile; and an elongate insertion member having a proximal end and a distal end and defining a longitudinal bore configured for receipt of the guide wire, wherein the cross-sectional profile of the bore is similar to the cross-sectional profile of the guide wire, wherein the insertion member has a non-circular cross-sectional shape substantially similar to and matingly engagable with a portion of the interior longitudinal channel of the body,wherein the guide wire is insertable through the longitudinal bore and disposed along an axis that is substantially coaxial with the interior longitudinal channel of the body such that the insertion member is slidably attachable to the guide wire, wherein the insertion member is insertable through the interior longitudinal channel of the body such that the body is slidably attachable to the insertion member, wherein when slidably attached, the distal opening of the body surrounds the cross-sectional shape of the insertion member, wherein the distal end of the guide wire is positionable in a desired location in the intervertebral space for guiding the insertion member to the desired location, and wherein the distal end of the insertion member is positionable in the desired location in the intervertebral space for guiding the body to the desired location.
