Shockwave Medical’s Shockwave S4 peripheral intravascular lithotripsy catheter, used for treating calcified lesions in below-the-knee arteries, won a CE Mark.

The device uses sound waves to break up calcified lesions blocking vessels and is designed to minimize trauma to the artery.

The S4 includes a battery-powered generator and hand-held connector cable, as well as a catheter which houses the sonic emitters within an integrated balloon.
