1. A nebulizing catheter constructed and arranged to extend through a flexible tube for bronchial therapy, said nebulizing catheter comprising:
a catheter sheath defining an interior space and an open tip;
a nebulizer positioned in said interior space, adjacent said open tip, said nebulizer including a piezoelectric device;
a one-way air valve positioned within the interior space of said catheter sheath; and
a reservoir positioned within the interior space of said catheter sheath between said one-way air valve and said piezoelectric device, said reservoir being constructed and arranged to retain a liquid mixture, wherein said liquid mixture is in flow communication with said piezoelectric device for nebulizing a portion of said liquid mixture into small droplets for use in bronchial therapy.
