Peripheral nerve block catheter

A method for manufacturing a catheter comprising:

• forming an elongated sheath defining a central lumen with a proximal end and a distal end
• incorporating a biocompatible material made from an echogenic material within the elongated sheath, wherein the echogenic material surrounds the central lumen;
• and
• attaching a connection fitting to the proximal end of the elongated sheath.

A method of using a catheter comprising:

• providing a catheter comprising:
• an elongated sheath defining a central lumen in communication with a proximal end and a distal end,
• an echogenic material made from a biocompatible material surrounding the central lumen, and
• a connection fitting attached to the proximal end of the elongated sheath;
• inserting an electro-stimulation needle comprising a beveled end and a conductive wire electrically connected at an opposite end thereof through the central lumen such that the beveled end protrudes outwardly from the distal end of the central lumen;
• and
• puncturing a body wall with the beveled end of the electro-stimulation needle;
• positioning the catheter such that the beveled end is adjacent or proximate a nerve;
• and
• introduce stimulating electrical currents through the electro-stimulation needle.
