    摘要： Partial or total occlusions of fluid passages within the human body are removed by positioning an array of optical fibers in the passage and directing treatment radiation pulses along the fibers, one at a time, to generate a shock wave and hydrodynamics flows that strike and emulsify the occlusions. A preferred application is the removal of blood clots (thrombin and embolic) from small cerebral vessels to reverse the effects of an ischemic stroke. The operating parameters and techniques are chosen to minimize the amount of heating of the fragile cerebral vessel walls occurring during this photo acoustic treatment. One such technique is the optical monitoring of the existence of hydrodynamics flow generating vapor bubbles when they are expected to occur and stopping the heat generating pulses propagated along an optical fiber that is not generating such bubbles.

    摘要： A fiber optic radiation transmission system is provided in which an optical fiber and a radiation source are connected to establish optical communication therebetween. Additionally, a connecting system is provided for connecting an optical fiber and a radiation source such that optical communication is established therebetween. The systems include a connector which carries the optical fiber therein. The connector is extendable within the system toward the radiation source to bring the optical fiber into optical communication with the radiation source. More particularly, the systems are configured in such a way that when the connector is extended sufficiently within the system, it seats the optical fiber relative to the radiation source under bias, thereby establishing a reliable optical connection. Once the optical connection is thus established, the connector engages a connection port associated with the radiation source to secure the system in a fully connected configuration appropriate for use. Thus, in a method of using such a system, the user simply extends the connector until the connector engages the connection port. The present invention thus provides efficient and reliable systems in which optical communication is established between an optical fiber and a radiation source.
