US Patent:

20050090801, Apr 28, 2005

Filed:

Oct 27, 2003

Appl. No.:

10/694235

Inventors:

N. Racz - Irving TX, US
Christopher Wiley - Hanover NH, US

International Classification:

A61M031/00

US Classification:

604500000, 604164070

Abstract:

An apparatus and method to insert a spinal catheter and minimize incidence of post dural puncture headache. The apparatus typically includes a support needle with a non-cutting piercing tip and an exteriorly mounted catheter. The catheter gauge is reduced, while ease of use is increased by the exterior mounting. The catheter may include a kink sleeve that protects against kinking when bent during use. A central stylet maybe included to prevent entry of matter into the support needle opening during insertion. Methods using a single stick insertion procedure allow for catheter placement to be determined and adjusted based on physical feedback obtained during the single stick insertion.

Abstract:

A method of using an assembly to insert a flexible spinal needle and minimize incidence of post dural puncture headache is provided. The assembly typically includes a support needle with a non-cutting piercing tip and an exteriorly mounted flexible needle. The flexible needle gauge may be reduced, while ease of use is increased by the exterior mounting. The flexible needle provides increased flexibility allowing for movement of a patient's torso after insertion. A central stylet may be included to prevent entry of matter into the support needle opening during insertion. In other embodiments, methods for allowing single stick insertion procedures to provide better placement by allowing placement to be determined and adjusted based on physical feedback obtained during the single stick insertion.
