Abstract
Catheter system, devices and methods for diagnosing and treating lateral stenosis causing back pain and or leg pain. The devices comprise a tubular part for insertion into a working cannula to self-position itself safely within the foramen, and minimize the risk of displacement medially or laterally, to prevent nerve or dura injury. An expandable membrane is configured to maintain the catheter device within the foramen. Expansion of this membrane would decompress the nerve within the foramen by opening the foraminal canal as the membrane expands.
Claims9
A method of treating impingement of a nerve of a spinal canal caused by spinal stenosis within a human body, said spinal canal including a vertebral foramen, the method comprising the steps of:
- inserting a cannula containing a sharp stylet through the skin and fascia of the human body towards the spinal canal;
- removing the sharp stylet;
- inserting a blunt stylet through the cannula towards the spinal canal;
- removing the blunt stylet;
- inserting a catheter through the cannula, said catheter including a plurality of inflatable members, said inflatable members being of varying sizes and movable from a deflated to an inflated position;
- inflating at least one of said plurality of inflatable members within the vertebral foramen;
- deflating said at least one inflatable member;
- and removing said at least one inflatable member and cannula.
