Aspects of the application relate to a method of manufacturing a cardiovascular implant. The method comprises forming a housing including side walls defining a cuboid. The housing has length, width and height dimensions, and the length is greater than the housing's width and height dimensions. Two opposite long sides of the housing are open. The method further comprises placing electronics including an antenna coil into said housing, and bonding thin walls to the open sides of the housing. The thin walls are thinner than the side walls of said housing.ワイヤレス回路は、気密性ハウジングのようなハウジングと、ハウジング内でコイル軸の回りに巻かれた少なくとも１つのアンテナコイルとを含む。コイル軸は、ハウジングの少なくとも１つの壁とほぼ平行であってもよく、コイル軸と平行な壁は、ハウジングの他の壁よりも実質的に薄い。【選択図】図１
