Method and apparatus for the measurement and medical treatment using an ultrasonic wave
First Claim
1. An apparatus comprising:
- means for injecting into a blood vessel of a biotic body an agent including a plurality of particles having means for one of producing gas and providing medication encapsulated therein; and
means for emitting a shock wave to a predetermined blood vessel in the biotic body with a pressure to effect breaking of the particles reaching the predetermined blood vessel so as to enable release of the means for one of producing gas and providing medication in the blood flowing in the predetermined blood vessel.

Abstract
An ultrasonic measuring apparatus and method operating as an ultrasonic echocardiograph and a doppler blood flow speed meter by creating numerous microbubbles as a contrast medium or reflector only in an intended blood vessel. The apparatus comprises an injector which injects into a vein of patient an agent which is a substance encapsulated in numerous microcapsules of several micrometer or less in diameter and distributed in a carrier liquid so that it produces microbubbles through the reaction with blood, and a shock wave transmitter which emits a shock wave with the dominant positive pressure from the body surface toward a specific blood vessel such as the root of the aorta so that only microcapsules in the specific blood vessel, among all dispersed in the whole body, are broken by the shock wave and the agent is released in the blood flow.

16. A method comprising the steps of:
-
injecting into a blood vessel of a biotic body an agent including a plurality of particles having means for one of producing gas and providing medication encapsulated therein; and emitting a shock wave to a predetermined blood vessel in the biotic body with a pressure sufficient to effect breaking of the particles reaching the predetermined blood vessel so that the means for one of producing gas and providing medication is released from the particles in blood flowing in the predetermined blood vessel. - View Dependent Claims (17, 18, 19, 20, 21)
