Abstract: A method of producing a flow of a fluid through a passage (24) defined in a rigid frame (22) comprises selectively actuating a flexible membrane (38) disposed across a midpoint of the passage (24) with an actuating system in a manner which produces a wave-like motion in the membrane (38) thereby causing a peristaltic movement of the fluid through the passage (24).

Abstract: A nozzle (12) for an oral irrigator device (10) having a guidance tip (34) with at least one orifice (36) at one end, and a nozzle spacer assembly (58) positioned around the at least one orifice (36). The at least one orifice is configured to expel a fluid as one of a jet, a spray, or any combination thereof. The nozzle spacer assembly (58) comprises at least two pairs of pliable spacers (60) that extend from the surface (35) for ensuring that the area at an entrance of an interproximal space between two teeth are treated, and (ii) establishing an improved angle of impact of the fluid expelled from the orifice.

Abstract: An apparatus for creating a flow of gas comprises a frame having a passage defined therethrough. The passage extends a length along a central longitudinal axis from an inlet to an outlet and has a first side and a second side. A flexible pumping membrane is disposed within the passage. The membrane has a first edge coupled to the first side of the passage at a midline thereof and a second edge, disposed opposite the first edge, coupled to the second side of the passage at a midline thereof. The membrane segregates the frame into an upper portion and a lower portion. The apparatus also includes an actuating system which is structured to selectively move portions of the membrane toward either the upper portion or the lower portion of the frame in a manner which causes a wave-like movement in the pumping membrane and creates the flow of gas.

Abstract: The invention relates to a system 1 for planning a treatment of a subject 2. A treatment planning device 39 determines a treatment position of a treatment device like a needle or catheter which comprises an energy delivery element not completely encircling the treatment device. The determined treatment position is a position in a four-dimensional space being representable by three Cartesian coordinates and an angular coordinate defining the angular orientation of the treatment device with respect to a rotation around its longitudinal axis. The treatment device is then arranged in accordance with the treatment position. Since not only the three-dimensional position of the treatment device is determined, but also a rotational position of the treatment device with respect to a rotation of the treatment device around its longitudinal axis, the energy delivery can be very accurately planned, leading to a reduction of unwanted therapy side effects.

Abstract: Disclosed is an ultrasound array comprising a plurality of ultrasound transducer elements (20) on a carrier (10), said carrier further carrying an actuator arrangement (30, 30′) of a material having an adjustable shape in response to an electromagnetic stimulus, e.g. an electro active polymer or optically responsive polymer, wherein the material is arranged to change the orientation of said ultrasound transducer elements in response to said stimulus. This facilitates configurable beam shaping and/or body contour matching with the ultrasound array. An ultrasound system (100) comprising such an ultrasound array is also disclosed.
