DEVICES, SYSTEMS, AND METHODS FOR SPG BLOCK AND NEURO-MODULATION

摘要

Neuro-modulation of the SPG is achieved by direct delivery of medication that includes a CGRP receptor antagonist using a trans-nasal drug delivery device with delivery features that may include an ergonomic grip, directional control and indicators, or radiopaque portions.

主权项

1. A drug delivery device for treating a pain condition, the device comprising:
a catheter member defining an extended body with a proximal portion and a distal portion, wherein the distal portion defines a curved portion and a delivery port; a handle at the proximal portion of the catheter; a first lumen and a second lumen in the catheter, wherein movement of an inner member allows egress out of the delivery port at the distal portion of the catheter; and a reservoir within the device holding a medication that includes a calcitonin gene-related peptide (CGRP) receptor antagonist.
