Abstract

A nasal implant delivery tool includes an inner handle, an outer handle, a needle, and a push rod. The inner handle includes a loading chamber configured to receive a nasal implant. The outer handle is configured to move axially relative to the inner handle. The needle extends distally from the inner handle and has a central lumen and a distal opening. The push rod is configured to move the nasal implant from the loading chamber, through the central lumen, and out the distal opening of the needle. The push rod is coupled to the outer handle such that the push rod moves axially relative to the inner handle when the outer handle is moved axially relative to the inner handle. Also described herein are nasal implant guides and methods of using nasal implant delivery tools and nasal implant guides.
