Method of controlling drug release by resonant sound wave
First Claim
Patent Images
1. A method of controlling a release of a drug from a drug carrier or drug holding structure comprising the steps of:
- measuring the acoustic characteristics of a drug carrier or drug holding structure in the region in which a drug is to be released in order to calculate the resonance frequency of said drug carrier or drug holding structure and irradiating said drug carrier or drug holding structure having a sharp acoustic resonance with a sound wave having a frequency including the resonance frequency of said drug carrier or drug holding structure in said region thereby controlling the release of said drug from said drug carrier or drug holding structure.

Abstract
A drug carrier carrying a drug is introduced to a diseased region of the living body while it is observed in the B mode echograms. The drug carrier is irradiated with an ultrasonic wave for strongly vibrating the drug carrier, thereby releasing the drug from the drug carrier for curing the diseased portion.
