Abstract

Disclosed monopolar and bipolar tissue lacerators can comprise a wire partially covered by electrical insulation, wherein the wire has a kink defining an inner curvature, wherein the wire is exposed through the insulation at one or two exposed regions along or near the inner curvature of the kink, wherein the wire is configured to conduct electrical energy through the one or two exposed regions and through a tissue target positioned adjacent the inner curvature to lacerate the tissue target via the electrical energy. The tissue target can be a native or prosthetic heart valve leaflet in a patient's heart.
