Apparatuses, capacitor arrays, and methods for generating therapeutic compressed acoustic waves (e.g., shock waves). In the apparatuses and at least some of the methods, a plurality of electrodes can disposed in a chamber that is defined by a housing and configured to be filled with liquid, and a plurality of capacitors can be electrically connected to the electrodes and can be carried by (e.g., physically coupled to) the housing. Voltage pulses can be applied simultaneously to the plurality of electrodes (e.g., to begin to vaporize and ionize portions of the liquid to provide at least one inter-electrode conductive path between the plurality of electrodes) and to the capacitors to charge the plurality of capacitors). The plurality of capacitors can be configured to, upon reaching a threshold charge, discharge to the plurality of electrodes (e.g., to generate one or more arcs along the one or more inter-electrode conductive paths to vaporize additional portions of the liquid and generate one or more acoustic shock waves). In the capacitor arrays, a plurality of capacitors can be coupled to the one or more circuit boards with a first portion of the capacitors arranged in a first pattern defined by a plurality of capacitor sets, a second portion of the plurality of capacitors can be arranged in a second pattern defined by a plurality of capacitor sets, with the sets defining the first pattern connected in parallel, the sets defining the second pattern connected in parallel, and the circuit board(s) can be configured to be coupled to an electrode such that the electrode is in electrical communication with the capacitors and is fixed in at least two degrees of freedom relative to the one or more circuit boards.一種用於產生醫療壓縮聲波(譬如，脈衝)之裝置、電容器陣列、及方法。在該等裝置及至少某些該等方法中，複數個電極可設置於藉一外殼界定且佈設成充滿液體之一容室中，且複數個電容器可與該等電極電氣連接且可藉該外殼支撐(譬如，實體連結)。電壓脈波可同時施加至該複數個電極(譬如，使該液體之部份開始汽化且離子化以提供該複數個電極之間的至少一極間導電路徑)，及施加至該等電容器以充電該複數個電容器。該複數個電容器可佈設成，當達一臨界充電時，放電至該複數個電極(譬如，沿該一個或更多極間導電路徑產生一個或更多極間電弧，使該液體其他部份汽化且產生一
