Abstract

One embodiment is directed to instrumentation for performance of a spinal implantation procedure. In one form, this instrumentation includes: a tube device with an inner surface defining a passage from a proximal end portion to a distal end portion, a conveyor including a threaded conveying rod to be received in the passage of the tube device that can be rotated in the tube or moved in translation along the passage, and a deformable prosthesis structured to move through the passage of the tube by rotating the threaded conveying rod while at least a portion of the deformable prosthesis is positioned between the inner surface and the rod. Optionally, a tool to maintain position of the tube device can be included that has a jaw mechanism, among other things.

Claims

1. A method, comprising:

operating an instrument that percutaneously extends into a patient'"'"'s body, the instrument including a tube, a threaded conveying rod extending inside the tube, a proximal end portion and a distal end portion;

placing the instrument into a position with the distal end portion in proximity to a spinal structure of the patient'"'"'s body while the proximal end portion remains outside the patient'"'"'s body;

with a deformable prosthesis including an elongate implant material extending along a longitudinal axis between a distal end and an opposite proximal end, the elongate implant material being positioned between an inner surface of the tube and threading on the rod in purchase with the elongate implant material of the prosthesis so that the longitudinal axis of the implant material is offset from a longitudinal axis of the rod, moving the deformable prosthesis through the tube by rotating the rod while in the position; and

depositing at least a portion of the elongate implant material of the prosthesis on the spinal structure with the instrument.

2. The method of claim 1, which includes reversing direction of said rotating to change direction of the moving of the deformable prosthesis through the tube so that the elongate implant material retracts from the spinal structure.

3. The method of claim 1, which includes turning a handle coupled to the rod to perform said rotating.

4. The method of claim 1, which includes:

attaching a tool to the tube;

maintaining location of the tube relative to rod during said rotating; and

holding down the rod by engaging a travel stop fixed to the rod in rotating bearing relationship with a member connected to the tool.

5. The method of claim 1, which includes:

forming a percutaneous passageway through the patient'"'"'s body;

inserting the instrument through the passageway; and

visualizing said operating of the instrument with an endoscope device.

6. The method of claim 1, which includes passing the deformable prosthesis through an accessway to the passage in the tube.

7. The method of claim 6, which includes:

closing the accessway by moving the rod in translation along an axis in a first direction; and

opening the accessway by moving the rod in translation along the axis in a second direction opposite the first direction.

8. The method of claim 1, wherein the rod and elongate implant material are positioned eccentrically in the tube.

9. The method of claim 1, wherein the elongate implant material is continuous between its proximal and distal ends.

10. The method of claim 1, wherein moving the deformable prosthesis through the tube by rotating the rod while in the position includes advancing the distal end of the elongate material through the tube while advancing the proximal end of the elongate material from a location outside the tube into the tube by rotating the rod.
