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 system for 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 system comprising:
- a catheter;
- a plurality of inflatable members, said inflatable members being of varying sizes movable from a deflated to an inflated position, one of said inflatable member located within the catheter in a deflated position, said inflatable member capable of being advanced outwardly of said catheter, said inflatable member being sized and configure to alleviate the nerve impingement when in said inflated position;
- and
- a cannula for housing said catheter, said cannula having a blunt end with at least one removable stylet having a blunt end located internally of said cannula.
