Systems and methods for opening of a tissue barrier
First Claim
1. A method for opening a tissue to a target value using microbubbles, comprising;
- targeting a region of said tissue to open;
determining at least one acoustic parameter corresponding to said target value, wherein said at least one acoustic parameter is selected to control a magnitude and a type of one or more acoustic cavitation events to open said tissue to said target value, and wherein said target value corresponds to a treatment and/or imaging value to allow passage of certain molecules and/or agents; and
applying an ultrasound beam at said at least one acoustic parameter to said targeted region such that said tissue is opened with said microbubbles to said target value.

Abstract
Systems and methods for opening a tissue to a target value using microbubbles are disclosed herein. In an embodiment of a method for opening a tissue to a target value using microbubbles, a region of the tissue is targeted for opening, an acoustic parameter corresponding to the target value is determined, and an ultrasound beam is applied to the target region at the acoustic parameter such that the tissue at the target region is opened to the target value with the microbubbles. The acoustic parameter can be selected to control an acoustic cavitation event and, in some embodiments, controlling an acoustic cavitation event can include controlling a location, number and/or magnitude of acoustic cavitation events.
