Abstract: The present invention relates to determining the rotation of an interventional device in an ultrasound field. An interventional device is provided that is suitable for being tracked in an ultrasound beam of a beamforming ultrasound imaging system by correlating transmitted ultrasound signals from the beamforming ultrasound imaging system as detected by ultrasound receivers attached to the interventional device with the beamforming beam sequence of the ultrasound signals. The interventional device includes a longitudinal axis (A-A′), a first linear sensor array (12) comprising a plurality of ultrasound receivers (R1 . . . n) wherein each ultrasound receiver has a length (L) and a width (W), and wherein the array extends along the width (W) direction. Moreover the first linear sensor array (12) is wrapped circumferentially around the interventional device with respect to the axis (A-A′) such that the length (L) of each ultrasound receiver is arranged lengthwise with respect to the axis (A-A′).

Abstract: The invention relates to a transducer laminate in which electrical contact is made between electrical conductors (C1, C2) and a transducer layer (TY). The transducer laminate includes two adhesive-coated foils (F1, F2), whose adhesive coatings (AC1, AC2) are arranged to face each other. At a first position (A-A′) along the length of the two electrical conductors (C1, C2) the two electrical conductors (C1, C2) are sandwiched between the adhesive coatings (AC1, AC2) of the two adhesive-coated foils, and the transducer layer (TY) is also sandwiched between the two electrical conductors (C1, C2) such that electrical contact is made with the electrodes (E1, E2) on the transducer layer (TY). At a second position (B-B′) along the length of the two electrical conductors (C1, C2) the two electrical conductors (C1, C2) are sandwiched between the adhesive coatings (AC1, AC2) of the two adhesive-coated foils and there is no transducer layer (TY) sandwiched between the two electrical conductors (C1, C2).

Abstract: The invention relates to a transfer stack (TS) for transferring a portion of a foil within a perimeter (P) that includes a transducer (T) to an article (A) such as a medical device or a medical needle. The transfer stack includes a carrier substrate (CS), a foil (F) having a transducer (T) incorporated therein, and the transducer is laterally surrounded by a perimeter (P). The foil (F) is separable from the carrier substrate (CS) by overcoming a first peel retaining force (PRF1). An adhesive layer (AL) is also attached to the foil. The adhesive layer (AL) is configured to provide adhesion between the foil (F) and an article (A) such that when the article (A) is attached to the foil via the adhesive layer (AL) the foil (F) is separable from the surface of the article (A) by overcoming a second peel retaining force (PRF2). The second peel retaining force (PRF2) is greater than the first peel retaining force (PRF1).

Abstract: The invention relates to a medical device having reduced susceptibility to EMI. The medical device includes a body, a first electrical conductor, a second electrical conductor, a first polarized transducer, and a second polarized transducer. The first electrical conductor and the second electrical conductor each extend along the body. The first polarized transducer and the second polarized transducer are attached to the body such that their outer faces have opposite polarity. Moreover, the first polarized transducer and the second polarized transducer are connected between the first electrical conductor and second electrical conductor either i) electrically in series and with the same polarity; or ii) electrically in parallel and with the same polarity.
