Methods and devices for lithotripsy procedures. A lithotripsy balloon catheter includes an elongate catheter shaft, an inflation lumen, a multilayer inflatable balloon in fluid communication with the inflation lumen located toward, or at, a distal section of the elongate catheter shaft, and at least one lithotripsy emitter within the multilayer inflatable balloon capable of generating an acoustic pressure wave within an inflation medium when the multilayer inflatable balloon is inflated. The multilayer inflatable balloon includes a first layer and a second layer having a combined wall thickness. The first layer is made of a first polymer material and the second layer is made of a second polymer material, where the second layer is an inner layer relative to the first layer. The multilayer inflatable balloons in accordance with the present disclosure may exhibit a higher rupture strength as compared to a similar, but monolithic, balloon.

The balloon catheter of claim, wherein the taper at the distal end of the balloon provides a more gradual transition in radial width when crossing a lesion, as compared to the taper at the proximal end of the balloon.
The balloon catheter of claim, wherein the taper at the distal end of the balloon includes a taper length of from about 3 mm to about 10 mm, and/or a taper angle of from about 10° to about 25°.
The balloon catheter of claim, wherein the distal end of the balloon provides less crossing resistance when crossing a lesion due to increased taper length and/or shallower taper angle at the distal end of the balloon.
