Abstract
An ultrasound catheter with fluid delivery lumens, fluid evacuation lumens and a light source is used for the treatment of intracerebral hemorrhages. After the catheter is inserted into a blood clot in the brain, a lytic drug can be delivered to the blood clot via the fluid delivery lumens while applying ultrasonic energy to the treatment site. As the blood clot is dissolved, the liquefied blood clot can be removed by evacuation through the fluid evacuation lumens.
Claims20
An apparatus for treating a blood clot resulting from an intracranial hemorrhage in a brain of a patient, the apparatus comprising:
- a tubular body configured to be advanced through a patient's skull, the tubular body including a distal portion configured for advancement into the blood clot in the brain of the patient, the tubular body including a central lumen, a separate fluid delivery lumen configured to deliver a therapeutic agent into the patient's brain, and a separate evacuation lumen configured for evacuating clot material;
- and
- an inner core comprising an ultrasound radiating element configured to be advanced into the central lumen of the tubular body and configured for transmitting ultrasound energy to the blood clot.
An apparatus for treating a blood clot in a brain, the apparatus comprising:
- a tubular body having a distal portion that is configured to be advanced into a blood clot in a brain of a patient;
- wherein the tubular body has a central lumen, a fluid delivery lumen configured to deliver a therapeutic agent, and an evacuation lumen configured to evacuate a portion of the blood clot;
- an inner core disposed within the central lumen;
- and
- one or more ultrasound radiating elements coupled to the inner core, the one or more ultrasound radiating elements being configured to transmit ultrasound energy to the blood clot.
An apparatus for treating a blood clot in a brain, the apparatus comprising:
- a tubular body having a distal portion that is configured to be advanced into a blood clot in a brain of a patient;
- a central lumen formed in the tubular body;
- a fluid delivery lumen, separate from the central lumen, formed in the tubular body;
- an evacuation lumen, separate from the central lumen and separate from the fluid delivery lumen, formed in the tubular body;
- a pressure sensor coupled to the tubular body and disposed in the fluid delivery lumen;
- an inner core disposed within the central lumen;
- and
- a plurality of ultrasound radiating elements coupled to the inner core, the ultrasound radiating elements being configured to transmit ultrasound energy to the blood clot.
