Study on measuring method of thrombolyses for wire type stirrer

A cerebral thrombus or blood clot might cause cerebral stroke and even decease if the clot could not be dissolved within several hours after it was formed. This paper presents a fundamental study on development of a new type of mechanical micro stirrer for assisting the dissolution of the thrombus with a few amount of thrombolytic agent. The micro stirrer is made of a simple structure with a piezoelectric. An efficient excitation method for stirring up the thrombus to get a quick dissolution is investigated. Furthermore, to evaluate the dissolution state in vivo, the method using the stirrer as both the stimulator to beat the clot and the probe to evaluate its solubility is proposed.
