A device 2600 for administering a substance includes an elongated body 2606 having a proximal end and a distal end, the elongated body defining an internal chamber 2614 extending between the proximal end and the distal end to direct the substance to the distal end, the distal end to connect with a tip 2610, the tip to be at least partially inserted into an orifice of a body lumen of a subject, the tip having a shape configured to reduce leakage of the substance from the orifice upon the at least partial insertion. The tip includes an opening to pass the substance from the internal chamber into the body lumen; and a transducer to emit an ultrasound wave from the tip into the body lumen, thereby administering the substance to tissue in the body lumen. |
