19. A method for removing a pacemaker lead comprising:
advancing a catheter along the pacemaker lead to a target site comprising fibrotic tissue, the catheter comprising a catheter body and a plurality of shock wave emitters disposed at a distal end of the catheter body, each shock wave emitter configured to generate a shock wave that propagates distally of the catheter body, wherein at least one shock wave emitter of the plurality of shock wave emitters comprises electrodes separated by a spark gap and at least one electrical connection to an electrode of at least one other shock wave emitter of the plurality of shock wave emitters; and
generating one or more shock waves to at least partially break up the fibrotic tissue so that the pacemaker lead can be removed.
