In some non-limiting embodiments or aspects, second metal strip 106b (eg, at least a portion thereof) may be disposed circumferentially about second medical device component 102b . Additionally or alternatively, the second metal strip 106b (e.g., at least a portion thereof) extends longitudinally (e.g., axially, along the axis of the second medical device component 102b) along the second medical device component 102b. (e.g., parallel to). In some non-limiting embodiments or aspects, at least a portion of the second metal strip 106b (e.g., upon mating the first medical device component 102a to the second medical device component 102b) , such that the first metal strip 106a can be in electrical contact and/or electromagnetically coupled with the second metal strip 106b) at an end (eg, a distal end, etc.) of the medical device.

Additionally or alternatively, the third resonant frequency spectrum may be different from the first resonant frequency spectrum and the second resonant frequency spectrum. In some non-limiting embodiments or aspects, a first medical device component 102a (e.g., its first mating element 110a) is connected to a second medical device component 102b (e.g., its second mating element 110a). mating element 110b), that antenna element (e.g., first antenna element 108a (e.g., first resonant structure 104a and/or first metal strip 106a) and second antenna element 108b).

It can work. For example, mating a first medical device component 102a (e.g., its first mating element 110a) to a second medical device component 102b (e.g., its second mating element 110b) causes the The first resonant structure 104a (for example, a first spiral resonator) and the second resonant structure 104b (for example, a second spiral resonator) are coupled (for example, by electromagnetic coupling) to form a third resonant structure 104a (for example, a first spiral resonator). A resonant circuit with a natural frequency can be formed. Additionally or alternatively, the third resonant frequency spectrum may include a third natural frequency of the resonant circuit.

For example, upon interrogating the medical device assembly 102 with an interrogation signal 112 (e.g., a multi-frequency electromagnetic signal), the reader 124 may receive (e.g., from the medical device assembly 102) at least one reflected signal (e.g., the first reflected signal 114a, the second reflected signal 114b, the third reflected signal 114c, any combination thereof, etc.), which may include an attenuated electromagnetic signal (e.g., the first, second, and/or third attenuated electromagnetic signal associated with the first medical device component 102a, the second medical device component 102b , and/or the mated medical device component, respectively) as described herein. In some non-limiting embodiments or aspects, each reflected signal (e.g., the first reflected signal 114a, the second reflected signal 114b, the third reflected signal 114c, any combination thereof, etc.) may include a backscattered signal, a retransmitted signal, any combination thereof, etc.

In some non-limiting embodiments or aspects, the reader 124 changes the respective resonant frequency spectrum (e.g., by at least one of amplitude attenuation, phase jump, frequency attenuation, any combination thereof, etc. in the reflected signal). , the first medical device component 102a, the second medical device component 102b , and/or the first, second, and/or third resonant frequency spectra associated with the mated medical device components, respectively). can be detected. For example, upon interrogating the first medical device component 102a using the interrogation signal 112, the reader 124 determines the amplitude attenuation, phase jump, frequency attenuation, etc. in at least one reflected signal corresponding to the first resonant frequency spectrum. The first resonant frequency spectrum may be detected by at least one of any combination, etc. Additionally or alternatively, upon interrogating the second medical device component 102b using the interrogation signal 112, the reader 124 detects an amplitude attenuation, a phase jump, a frequency attenuation in the at least one reflected signal corresponding to the second resonant frequency spectrum. , any combination thereof, and the like. Additionally or alternatively, upon interrogating a mated medical device component (e.g., first medical device component 102a mated with second medical device component 102b) using interrogation signal 112, reader 124: The third resonant frequency spectrum may be detected by at least one of amplitude attenuation, phase jump, frequency attenuation, any combination thereof, etc. in the at least one reflected signal corresponding to the third resonant frequency spectrum.
