An apparatus and methods for enhanced percutaneous epidural access for performing spine surgery, epidural procedures and medical device placement that includes a first percutaneous needle having a first lumen, a proximal end and a distal end, wherein the distal end is configured for placement in an epidural space at a first location, the first location being at least one level removed from a target lamina, a second percutaneous needle having a second lumen, a proximal end and a distal end, wherein the distal end of the second percutaneous needle is configured for placement in an epidural space at a second location, the second location being at least one level removed from a target lamina and opposite the first location, a light seeking tool that is coaxially movable within one of the first and second lumens, and a grasper tool that is coaxially movable within the other one of the first and second lumens and is configured to emit light so as to draw the light seeking tool and temporarily couple within the epidural space of the target lamina. |

1. An apparatus for enhanced percutaneous epidural access for performing spine surgery, the apparatus comprising:
a first percutaneous needle having a first lumen, a proximal end and a distal end, wherein the distal end is configured for placement in an epidural space at a first location, the first location being at least one level removed from a target lamina; a second percutaneous needle having a second lumen, a proximal end and a distal end, wherein the distal end of the second percutaneous needle is configured for placement in an epidural space at a second location, the second location being at least one level removed from a target lamina and opposite the first location; a light seeking tool that is coaxially movable within one of the first and second lumens; and a grasper tool that is coaxially movable within the other one of the first and second lumens and is configured to emit light so as to draw the light seeking tool and temporarily couple within the epidural space of the target lamina. |
