A bolus assembly is configured to receive and be removably coupled to a transducer assembly of an ultrasound probe assembly. The bolus assembly includes a housing assembly and at least one sealing member. The housing assembly has a body having first and second ends, and a sidewall extending therebetween, the body forming a cavity defined by the first end, second end, and sidewall, the cavity being configured to receive at least one transducer of a transducer assembly, a first passage extending through the second end of the body, the sidewall including at least one opening spaced-apart from the passage; and an acoustically transparent and distensible membrane attached to an entire outer periphery of the opening. The sealing member has a through hole and is positioned within the passage. The through hole is configured to receive the shaft. The sealing member is sealingly engaged with the shaft within the passage.

Devices, systems, and methods are disclosed for use in tomographic ultrasound imaging, large aperture ultrasound imaging and therapeutic ultrasound that provide for coupling acoustic signal transducers to body structures for transmitting and receiving acoustic signals. The acoustic signal transmission couplants can conform to the receiving medium (e.g., skin) of the subject such that there is an acoustic impedance matching between the receiving medium and the transducer. In one aspect, an acoustic coupling medium includes a hydrogel including polymerizable material that form a network structured to entrap an aqueous fluid inside the hydrogel. The hydrogel is structured to conform to the receiving body, and the acoustic coupling medium is operable to conduct acoustic signals between acoustic signal transducer elements and a receiving medium when the hydrogel is in contact with the receiving body such that there is an acoustic impedance matching between the receiving medium and the acoustic signal transducer elements.

A device including a focused ultrasound probe, a first balloon, and a second balloon. The first balloon can be located at least partially inside the second balloon. The inner balloon can be configured to act as a fluid interface, a mechanism for cooling, and a mechanism for changing tissue depth of a focal point of the probe. The second balloon can be filed with a thermosensitive hydrogel configured to turn from a fluid at room temperature to a gel at physiologic temperatures. The first and second balloons can be configured to create a fluid interface between the probe and targeted tissue of a patient.

A method for making a tough and compliant hydrogel. A precursor hydrogel is made of a first polymer selected to maintain high elasticity and a second polymer selected to dissipate mechanical energy. The precursor hydrogel is stretched to a multiple of its original length to form a pre-stretched hydrogel. The pre-stretched hydrogel is allowed to relax and is soaked in a biocompatible solvent to reach equilibrium swelling of the pre-stretched hydrogel whereby shear modulus of the hydrogel is reduced.

The present invention concerns a probe for treating an ocular pathology, comprising: o a ring (1) including a cone frustum (11) having a first end (111) suitable for supporting ultrasound generation means (2) and a second end (112) for coming into contact with an eye (4) of a patient, o ultrasound generation means (2) comprising a first base (211) intended to come to face the first end (111), and a second base (212) opposite the first base (211), remarkable in that the probe further comprises a flow regulator (3) for eliminating the bubbles contained in a coupling fluid flowing to the first base (211) when filling the probe with said fluid.
