INTEGRATED IPD DEVICES, METHODS, AND SYSTEMS

摘要

The present invention relates generally to various integrated Inter-Spinous Process Decompression, IPD, devices and methods for implantation thereof for treating spinal stenosis. Generally, in accordance with an exemplary embodiment of the present invention, the disclosed IPD system comprises an IPD tusk-shaped needle, an IPD tusk-shaped sizer, an IPD tusk-shaped implant tool, and an IPD implant.;Preferably, in accordance with an exemplary embodiment of the present invention, each of the IPD tusk-shaped needle, the IPD tusk-shaped sizer, the IPD tusk-shaped implant tool, and IPD implant are suitably configured for percutaneous insertion between a patient's spinous process. Most preferably, in accordance with an exemplary embodiment of the present invention, either the IPD tusk-shaped sizer or the IPD tusk-shaped implant tool is configured to be reversibly coupled to an IPD implant.
