APPARATUS AND METHOD FOR APPLICATION OF PHARMACEUTICAL TO TYMPANIC MEMBRANE FOR PHOTODYNAMIC LASER MYRINGOTOMY

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method for application of a pharmaceutical to the tympanic membrane in preparation for performing a photodynamic laser myringotomy.SOLUTION: A packaged kit for performing a photodynamic laser myringotomy includes a plurality of ear needles 18, 22, 24 having differently shaped absorbents on distal ends of the needles, a vial 12 of a single dose of an otolaryngologic formulation of mitomycin C, a diluent carrier 16 containing sterilized water, and a syringe 14, 44. The components of the kit are used to reconstitute the contents of the vial 12 with the water in the diluent carrier and to draw the reconstituted drug into the syringe 14, 44. A selected one of the plurality of ear needles 18, 22, 24 is then communicated with the syringe 14, 44. The syringe 14, 44 and needle 18, 22, 24 are used to inject the reconstituted drug into the absorbent pad at the end of the needle, and the absorbent pad containing the drug is used to apply the drug to the tympanic membrane. The application of the drug to the tympanic membrane prepares in particular for a photodynamic laser myringotomy.
