EMITTER FOR INTRAVASCULAR LITHOTRIPSY DEVICE WITH COATING FOR ENHANCED DURABILITY

Abstract: a catheter system () for treating a treatment site () includes an energy source (), an energy guide (a) and an emitter (). the energy guide (a) receives energy () from the energy source (). the emitter () includes (i) a guide distal end (d) of the energy guide (a), (ii) a plasma target () spaced apart from the guide distal end (d), the energy guide (a) emitting the energy () away from the guide distal end (d) and toward the plasma target () so that plasma () is generated at the plasma target (), and (iii) an emitter housing () secured to the energy guide (222a) and one of secured to and integrally formed with the plasma target () to maintain a relative position between the guide distal end (d) and the plasma target (). the emitter housing () includes a housing surface (s), with a coating (c) being provided on the housing surface (s). the housing surface (s) is formed from a first material, and the coating (c) is formed from a second material that is different than the first material.
