The surgical device includes a needle with lateral holes; a movable aspiration insert including an aspiration window that is sized to interface with one lateral hole of the plurality of lateral holes at a time, wherein the aspiration insert is disposed in a lumen of the needle; and a handle including a positioning means in communication with the aspiration insert, wherein the positing means is configured to actuate between a first state and a second state to move the aspiration insert a certain distance in a first direction along a longitudinal axis of the needle.

Abstract: Auger-based bone harvesting and delivery may be provided by a surgical device comprising: a cannula having first and second openings disposed on respective first and second ends; an auger, disposed within the cannula, including a flighting arranged around an auger shaft (aligned concentrically to the cannula); and a holding area in communication with the first opening. Harvesting may be performed by rotating, a cutting tip against a bone to collect tissue; and conveying the tissue to a holding area via the auger (that is co-rotated with the cutting tip). Delivery may be performed by inserting the first opening of the cannula into a delivery site; providing a graft material in a holding area in communication with a second opening of the cannula into contact with the auger; rotating the auger to convey the graft material to the delivery site via the auger and cannula.

Abstract: A method for applying ultrasound to activate a cavitation enhancing agent in the presence of a therapeutic compound and a microbial biofilm is provided. The ultrasound energy causes the cavitation enhancing agent to cavitate in the ultrasound field. The cavitation of the resultant bubble causes fluid streaming and shear forces at and near the biofilm, causing enhanced penetration of the therapeutic compound into the biofilm, and resulting in improved efficacy of the therapeutic compound against the biofilm. The method further includes cavitation enhancing agents which can be loaded with oxygen gas or combined with microbubbles which carry oxygen gas, which further potentiate antibiotic efficacy against the biofilm.

Abstract: Systems, methods, and devices are described to synthesize gas-filled microbubbles using a continuous flow chamber with a reaction volume and a sonicator positioned therein, by flowing a lipid solution at a first flow rate and gas at a first pressure into the reaction volume while ultrasonically agitating an interface between the lipid solution and the gas in the reaction volume using the sonicator member to generate a solution of gas-filled microbubbles, which solution can be concentrated to obtain a concentrated solution of microbubbles containing at least 23% of the core gas by volume.

Abstract: Acoustically activatable particles having low vaporization energy and methods for making and using same are disclosed. A particle of material includes a first substance that includes at least one component that is a gas 25° C. and atmospheric pressure. A second substance, different from the first substance, encapsulates the first substance to create a droplet or emulsion that is stable at room temperature and atmospheric pressure. At least some of the first substance exists in a gaseous phase at the time of encapsulation of the first substance within the second substance to form a bubble. After formation of the bubble, the bubble is condensed into a liquid phase, which causes the bubble to transform into the droplet or emulsion having a core consisting of a liquid. The droplet or emulsion is an activatable phase change agent that remains a droplet having a core consisting of a liquid at 25° C. and atmospheric pressure. The first substance has a boiling point below 25° C. at atmospheric pressure.

Abstract: Gas-filled microbubbles can be synthesized using a continuous flow chamber and a sonicator. The resulting microbubble solution can be size-sorted for a particular application, such as injection into a patient for gas delivery thereto. The microbubble solution may be concentrated to have greater than 50% volume gas while maintaining microbubble sizes below 10 ?m. Control of the microbubble generation process can yield highly stable microbubbles. The microbubbles may retain over half of their original gas payload for over three weeks while exhibiting minimal change in microbubble size. The systems, methods, and devices described herein thus allow for continuous or batch-wise continuous production of gas-filled microbubbles that readily release their gas payload when introduced into an under-saturated or de-saturated solution.
