Abstract
A method and system for locating a vascular opening and therapeutically sealing the wound with high intensity focused ultrasound (HIFU) is disclosed. A control unit (6) coupled to an applicator unit includes a processor (74) that automates the disclosed procedure, controlling various parameters of the diagnostic and therapeutic modes, including the intensity and duration of the ultrasonic energy emitted by the applicator unit. The disclosed method and system is and then discarded, is slipped over the particularly applicable to sealing a puncture made inserting a catheter during an interventional cardiovascular procedure.
Claims48
A method for sealing a vascular opening in a patient's body, comprising:
- a) performing at least one catheterization procedure on a patient whereby the opening is created;
- b) identifying a treatment zone to which ultrasonic energy should be applied to close the vascular opening;
- c) positioning an ultrasonic transducer applicator, comprising at least one ultrasound radiating surface, adjacent the zone determined in step (b);
- d) emitting a therapeutic ultrasound beam from the at least one radiating surface onto the treatment zone;
- e) administering a sufficient therapeutic ultrasonic energy to the treatment zone to seal the vascular opening created in step (a).
