Abstract

A drug delivery device includes an insert tube and an elongate plunger. The insert tube has a tubular wall that confines a passage and that has drug entrance and release ends. The drug release end has first and second radial parts, and is provided with a flexible grating that includes sets of first and second flexible strips. The first and second flexible strips extend from the first and second radial parts of the drug release end, respectively. The elongate plunger has a drug pushing end and an operating end, is slidably movable in the passage, and has a length sufficient to enable the drug pushing end to push a drug in the passage to move out of the passage and spread apart the first and second flexible strips for delivering the drug into a body cavity.
