摘要:
An interventional device (110) includes an elongate shaft and a transducer strip (112). The transducer strip includes a first edge and an opposing second edge. The first edge and the second edge are separated by a width dimension, and the first edge and the second edge each extend along a length direction of the transducer strip. The transducer strip also includes a piezoelectric transducer (116) that extends along a transducer direction that forms an acute angle with respect to the length direction. The transducer strip is wrapped in the form of a spiral around the elongate shaft of the interventional device such that the piezoelectric transducer forms a band around the elongate shaft. The width dimension is defined such that the adjacent first and second edges of consecutive turns of the spiral abut or overlap one another.

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).
