Focused systems · different generation methods
Electromagnetic against piezoelectric focused shockwave therapy machines: sourced energy and frequency ranges, price signals, and the exact FDA records located for each device.
The decision in plain English
Both of these are focused devices, so both concentrate energy at a selected depth rather than at the applicator surface. What differs is how they generate the wave in the first place: the Chattanooga Intelect Focus is electromagnetic, the EMS Swiss DolorClast Focused is piezoelectric.
That distinction is not marketing. It changes the shape of the focal zone, the way energy scales as you turn the machine up, and what a handpiece costs to replace when it wears out. A buyer searching for a focused shockwave machine will rarely be told this, so the explainer below the table covers it before the recommendation does.

What the gaps mean: The penetration-depth row is deliberately empty. Two sources we control or rely on disagree by 5 mm, and publishing either figure before the manufacturer rules on it would put an unverified number on a medical device page. The row will be filled in when the manufacturer collateral arrives.
An electromagnetic focused system drives a metal membrane with a coil and shapes the resulting wave with a lens or reflector. Energy scales smoothly across the range, which is why the Intelect Focus can publish a continuous 0.01 to 0.55 mJ/mm² band rather than a set of steps.
A piezoelectric system fires an array of crystals whose output converges on a geometric focal point. The focal zone is typically tighter and the wave front is generated with no moving mechanical part, which is the reason a piezoelectric handpiece can advertise a service life in the millions of impulses — EMS states over five million for this one.
Neither method is better in the abstract, and any page telling you otherwise owes you a comparison basis. Tighter focus favours precise, small-target work; a smoothly scaling wide energy band favours a clinic treating a broad mix of depths on one machine. The honest version of this decision is which of those two your caseload actually looks like.
Three different things get collapsed into the phrase “FDA approved”, and only one of them is approval. Each entry below names the exact record type and number found, and the indication exactly as the record words it. A record is specific to one model, one configuration and one indication; it never travels to another product.
No model-specific FDA clearance was located. What exists is a DJO establishment and device listing, which registers the facility and the device type. A listing is not a clearance and carries no indication.
A device-specific 510(k) was located. The cleared indication is narrower than the range of conditions the device is often discussed alongside.
Editorial judgment, not specification data
Everything above this point is sourced data. Everything in these cards is our opinion, and we sell some of the machines being judged. Read them as a starting point for your own diligence, not as a finding.
Mixed-caseload clinics that need a published number to budget against
Choose the Intelect Focus if you treat a range of depths on one machine and you need purchase and lease figures before you can get the spend approved.
Because it is the only device here publishing both a continuous energy band, 0.01 to 0.55 mJ/mm², and a price — $50,176.02, or $1,165 per month as an estimate.

Choose the DolorClast Focused if a current, device-specific clearance matters to your referrers or your risk posture, and you are prepared to run a quote process to get pricing.
Because it is the only machine in this comparison with a device-specific record in the table above — 510(k) K243279, decided August 2025 — where the Chattanooga entry is a listing rather than a clearance.
Pricing on request. This machine was quote-only everywhere we checked, so we publish no estimate for it.
Shockwave Source does not sell or lease this machine. Request pricing from its manufacturer directly.
Every monthly figure on this site is an estimate. Contract length, APR and buyout are confirmed at quote, not on this page.
Take this list to every quote you receive. If a vendor will not answer all five in writing, that is itself an answer.
No model-specific clearance was located. What exists is a DJO establishment and device listing, which registers the facility and the device type and carries no indication. That is not the same as a 510(k) or a PMA. We are requesting the exact clearance number and current labelling from the manufacturer and will publish it here when it arrives.
The record located is 510(k) K243279, decided in August 2025, and its scope is diabetic foot ulcers. That is the indication as the record words it. Any broader clinical claim needs to be checked against the device's current labelling before you rely on it, so ask EMS for the current instructions for use.
We are not publishing a figure yet. Our own catalogue states approximately 12 cm and the manufacturer's parent, Enovis, states 12.5 cm. Rather than round or pick between them, we are holding the row until the manufacturer confirms which is current. Everything else in the specification table is sourced and live.
Focused systems sit at the top of the market. Shockwave Source publishes $50,176.02 as a purchase estimate for the Chattanooga Intelect Focus, or $1,165 per month as a lease estimate. The EMS DolorClast Focused is quote-only, as are most manufacturer-direct focused devices, so no reliable published figure exists for it.
Neither is better without a stated basis. Piezoelectric arrays give a tighter focal zone and very long handpiece service life; electromagnetic systems scale smoothly across a wide continuous energy band. The right answer depends on whether your caseload needs precise small-target work or one machine covering a broad mix of treatment depths.
