Ideally, ultrasound localization should be applied by presenting an image that coincides with the shockwave delivery
path. Magna’s special design allows in-line ultrasound image acquisition without stopping the treatment session.
On-line imaging allows continuous monitoring and control of the stone fragmentation process without stopping
the treatment. Ultrasound and X-ray imaging can be operated and viewed simultaneously with the dedicated Duet
Magna image processing software.

therapeutic technologies in urology. Since
the groundbreaking introduction in 1986,
of the world’s first modular and compact
SWL system, further innovations have
been introduced to the market including:
•	 Linear Shockwave Therapy for Erectile
Dysfunction
•	 Low Intensity Shockwave Therapy for
Diabetic Foot Ulcer
•	 Dual-head shockwave lithotripsy
•	 Transurethral RF bipolar treatment for
BPH and prostate disease
•	 Stationary patient SWL with Integra,
incorporating In-line and On-line
fluoroscopy
•	 Holmium lasers for lithotripsy with
“Fibrex” optical fiber
To date, thousands of such devices
have been installed in over 70 countries
worldwide. These units are supported
by trained and experienced service
professionals.

Dual Shockwave
Lithotripsy
Electromagnetic DSWL
Double Shockwave Lithotripsy
Dual Magna introduces the combination of electromagnetic
technology and the double shockwave concept allowing for some
clear and unique advantages in the field of shockwave lithotripsy.
The Butterfly Focal Area
The Duet Magna is equipped with two reflectors and performs Double
Shockwave Lithotripsy (DSWL) from these two sources.
DSWL results in the formation of a unique Butterfly Focal Area that concentrates pressure to the stone from two
different angles, and spreads the “head and tail” of the shockwave volume to reduce the risk of kidney damage. In
fact, the Duet Magna roughly converts the focal volume to a sphere, which is considered the ideal focal volume for
lithotripsy.  The Butterfly Focal Area is superior to the conventional ellipsoid, or “cigar”, that only utilizes the central
section of the focal area.  This renders the “head and tail” of the focal area useless in terms of stone disintegration and
only contributes to kidney damage
Urological
Procedure
Options
The treatment table enables
comfortable Shockwave lithotripsy
treatment as well as other urological
procedures. The table is electrically
operated on three axes plus the
Trendelenburg movement.
Distribute the Energy to Reduce
Renal Damage
The Duet Magna, like its predecessor, the electro-
hydraulic Duet, causes significantly less kidney
damage than treatments with a single reflector. The
clear advantage of Double Shockwave Lithotripsy
lies in the fact that the total number of shocks is
divided between two areas of the kidney so that
only half of the shocks propagated towards the
stone pass through the lower part of the kidney,
while the other half pass through the upper part.
C-arm Options
A variety of fluoroscopy units can be used with the Magna for stone
localization, 3Dscope dedicated systems or general purpose C-arms.
C-arms from a variety of manufacturers
can easily be coupled to the Duet Magna,
and can be used for lithotripsy
as well as for traditional urological
procedures.
Direx offers 3DScope Premium, a
dedicated, motorized, remote controlled
unit, with high quality digital imaging.
•	 Mechanically built with required
height and length to match the focal
point of Magna,
it interconnects mechanically as a
single unit.
•	 Motorized rotation movement for fast
and precise localization.
•	 Remote controlled from Magna
console, thus allowing treatments
with minimal possible radiation
to the operators.
•	 Foldable arm leading to easy
transportation for mobile systems.
Reducing Kidney Damage
An Indiana University study on Double Shockwave Lithotripsy (performed
on the Duet Magna’s predecessor device) showed a 5-fold reduction in
kidney damage*. “The lesion produced by 2400 SWs (1200 SWs/head,
power level 10) at 120 SWs/min in alternating mode was quite low (0.22
±0.09% FRV) and compares favorably with the lesion (1.08 ±0.38% FRV)
produced by 2400 SWs delivered with the HM3 Lithotripter at 120 SWs/
min (24 kV)…” *Handa et al. Journal of Urology, February 2009
