Methods, Systems, and Devices for the Treatment of Stenosis

摘要

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. Inserts may be used in connection with the expandable member.

主权项

1. A method for treating impingement of a nerve within a human body, the method comprising:
providing a bendable guide wire having an expandable member located within the catheter; introducing the guide wire into the general proximity of the impinged nerve; advancing the expandable member from the cavity; expanding the expandable member; alleviating the pressure of the nerve impingement with the expanded expandable member; and removing the guide wire from the human body.
