Abstract: A method for fabricating a multi-cell electroacoustic transducer comprises placing a rail layer onto a base, the rail layer comprising a plurality of apertures arranged in an array, filling cavities in the rail layer with a polymer, and applying a flexural plate to the rail layer. The transducer achieves high transmission sensitivity across a broad bandwidth. The transducer may be designed to have a broad or a focused directivity pattern, or may be multi-frequency, depending on the particular application and has a range of applications.

Abstract: The present invention relates to a transducer device having a planar array of electroacoustic cells, each including a piezoelectric bilayer unit. The transducer device achieves high transmission sensitivity across a broad bandwidth. The transducer device may be designed to have a broad or a focused directivity pattern, or may be multi-frequency, depending on the particular application and has a range of applications. For example, the transducer device may be used with an implanted passive ultrasonically excitable resonating sensor, to excite the sensor and/or to interrogate the sensor, for example in conjunction with Doppler-based analysis of the resonance frequency of the sensor, and/or to locate an implanted sensor. The invention also relates to a method of manufacturing the device.

Abstract: The present invention discloses a capsule configured for controllably remaining within a patient's body for a certain period of time as well as a system comprising the capsule thereof. The invention also discloses a capsule being configured and operable for electrical stimulation, as well as a system comprising the capsule thereof.

Abstract: A capsule to be ingested by a subject, the capsule may include an outer enclosure configured to dissolve in gastric juice; a secondary enclosure that is permeable for gastric juice, is at least partially surrounded by the outer enclosure when in a folded state, and has a fully expanded volume; and an expandable polymer element that is surrounded by the secondary enclosure; wherein a fully expanded volume of the expandable polymer element exceeds the fully expanded volume of the secondary enclosure.

Abstract: An apparatus, system and method for re-canalization or opening a passage through an occlusion in a blood vessel is disclosed. The apparatus and method, which are appropriate for both cardiovascular as well as peripheral vessels, use hydraulic pressure to drive a vibratable member, and the system includes a control unit to permit the frequency or amplitude of oscillation of the vibratable member to be adjusted to suit the morphology or hardness of the target occlusion. Also disclosed is a method for adjusting the force of vibration.
