Web5 okt. 2005 · A time-domain finite-difference solution to the equations of linear elasticity was used to model the propagation of lithotripsy waves in kidney stones. The model was used to determine the loading on the stone (principal stresses and strains and maximum shear stresses and strains) due to the impact of lithotripsy shock waves. The simulations … WebA shock wave generator suitable for use in an extracorporeal lithotripsy device to disintegrate calculi in a life form in vivo has a flat coil connectable to a high voltage supply, a membrane assembly disposed opposite the coil and a housing, closed on one side by the membrane, filled with a shock wave transmissive fluid. The membrane assembly has a …

Webusing extracorporeal shock wave lithotripsy (referred to herein as lithotripsy) for a pacemaker or defibrillator patient: • Lithotripsy has the potential to permanently damage the implanted device. • Specific programming steps may prevent potential interactions. • Device function should be verified following the procedure. Web28 jun. 2005 · Cavitation plays a varied but important role in lithotripsy. Cavitation facilitates stone comminution, but can also form an acoustic barrier that may shield stones from subsequent shock waves. In addition, cavitation damages tissue. Spark-gap lithotripters generate cavitation with both a direct and a focused wave. The direct wave … cycloplegics and mydriatics
