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.

1. A method comprising:
passing a solid needle (1) coupled to a guide wire (4) between a patient's spinous processes (7); removing said needle (1) and threading said guide wire (4) between said spinous processes (7), wherein this step comprises creating an exit puncture wound (8) by pushing said needle (1) between a patient's spinous processes (7) until said needle (1) exits said patient's skin (5) and while leaving said guide wire (4) between said spinous processes (7); passing an inter-spinous process decompression (IPD) tusk-shaped sizer (9) guided by said guide wire (4) between said spinous processes (7); imaging said IPD tusk-shaped sizer (9) between said spinous processes (7) to determine a suitable IPD implant (16) size; removing said IPD tusk-shaped sizer (9) and leaving said guide wire (4) between said spinous processes (7); feeding said guide wire (4) through an IPD tusk-shaped implant tool (23) and coupling the guide wire (4) to an IPD implant (16); passing said IPD tusk-shaped implant tool (23) guided by said guide wire (4) and said IPD implant (16) coupled to the end of said guide wire (4) between said spinous processes (7); imaging said IPD implant tusk-shaped tool (23) between said spinous processes (7) to determine IPD implant (16) positioning; positioning and leaving said IPD implant (16) between said spinous processes (7); and removing said IPD implant tusk-shaped tool (23).
