DRUG DELIVERY BLADE AND METHODS FOR DELIVERING A DRUG DEPOT TO A TARGET SITE

摘要

A drug delivery blade for delivering a drug depot to a treatment site in a patient is disclosed. The drug delivery blade includes a shaft defining a longitudinal axis of the blade, a lumen that extends longitudinally from a proximal end of the shaft to a distal end of the shaft, a first beveled cut that forms a sharpened tip at the distal end of the shaft, and a flared portion near the distal end of the shaft. The flared portion of the blade includes two radially- extending blade segments having sharpened leading edges that allow the drug delivery blade to cut tissue when the blade is advanced toward a treatment site. Methods of using the drug delivery blade are also disclosed.
