SEISMIQ™ Intravascular Lithotripsy System

SEISMIQ™ Peripheral Intravascular Lithotripsy Catheter

SEISMIQ is the next-generation intravascular lithotripsy (IVL) offering that combines advanced deliverability, visibility, consistent acoustic profiles, and precise control to optimize IVL treatment. Every detail is purposefully engineered to give operators confidence—whether navigating challenging anatomies or delivering targeted therapy with clarity and consistency.

Highly deliverable catheter compatible with .014" guidewires, 5 Fr sheaths for 2.5-3.0 mm diameters, and 6 Fr sheaths for 3.5-8.0 mm diameters.
5 emitter stations on the 60 mm balloons and 4 emitter stations on the 40 mm balloons that are helically arranged along the balloon catheter. Each station contains 2 emitters positioned 180° apart, with adjacent emitter stations offset by 72° to provide circumferential acoustic energy delivery.
Consistent acoustic output across all emitter stations along the balloon.
Fully sterile catheter that eliminates the need for sterile bagging of the handle and has no lockout periods between treatment cycles.
On/off emitter selectivity to preserve pulses and target acoustic output where it matters most.

Only for use in the peripheral vasculature

How SEISMIQ works

SEISMIQ delivers targeted acoustic pressure to modify calcified arterial lesions.

SEISMIQ’s advanced laser energy source is distributed through optical fibers, then converted to acoustic pressure waves by generating a plasma event when the laser energy hits each emitter's metallic backstop within the balloon. The initial plasma plume fractures the calcium, while a secondary cavitation bubble further expands the fractures.

Why choose SEISMIQ

Get the most from every pulse

Shockwave electrode configuration vs SEISMIQ emitters configuration.

The most consistent pressure per pulse

With a more consistent acoustic output profile across all five emitter stations, you can now target even the most challenging lesions with unparalleled force.

Seismiq catheter with indicators pointing to radiopaque emitters.

A whole new level of control

Improved radiopaque emitters allow you to precisely align acoustic pressure delivery to the calcium. Additional on/off emitter selectivity enables you to preserve pulses and target acoustic output where it matters most.

Delivering what is possible

A streamlined profile with lower tracking force combined with improved flexibility and kink resistance means you’re in control of delivery. Cross complex anatomy and take on calcified lesions.
