Intravascular lithotripsy (ivl) catheter and method of performing ivl

Abstract

An intravascular lithotripsy (IVL) catheter including at least one acoustic wave generator and a drug-releasing coating on the exterior of the catheter, the drug-releasing coating including a therapeutic agent including an antiproliferative drug. A method of performing IVL includes inserting an IVL catheter to a target site in a body lumen, wherein the target site includes a calcified plaque and the body lumen includes a blood vessel. The method includes emitting an acoustic wave from at least one acoustic wave generator in the IVL catheter to emit an acoustic wave to the target site. The method includes removing the IVL catheter from the target site. The IVL catheter is the IVL catheter including the drug-releasing coating; or the IVL catheter is the IVL catheter including the drug-releasing coating and the catheter includes a balloon, and prior to the removal of the IVL catheter and after the emitting of the acoustic wave to the target site the method further includes dilating the target area with the balloon of the IVL catheter; or the target area is dilated with a balloon catheter or stent after the removal of the IVL catheter from the target site, the balloon catheter or stent including a drug-releasing coating thereon including a therapeutic agent including an antiproliferative drug.
