Abstract
Lithotripter apparatuses and methods are provided for selectively modifying an acoustic pressure field and can include a shock wave source operable to generate a shock wave having a substantially axisymmetric acoustic pressure field, an acoustic focusing member positioned between the shock wave source and a target, and an acoustic barrier positioned between the shock wave source and the acoustic focusing member. The acoustic barrier can be operable to selectively block a portion of the shock wave generated by the shock wave source such that the substantially axisymmetric pressure field is transformed into a modified acoustic pressure field.
