Extracorporeal Lithotripter

Electromagnetic DSWL

Lithotripsy with Double Shockwavesinput:
output:The Duet Magna system introduces the double shockwave concept and electromagnetic technology, which provides distinct and tangible benefits in the field of shockwave lithotripsy.

Mitigating Kidney Damageinput:
output:A 5-fold reduction in kidney damage was observed in a study conducted at Indiana University on Double Shockwave Lithotripsy, which was performed on the predecessor device to the Duet Magna. "The lesion produced by 2400 SWs (1200 SWs/head, power lever 10) at120 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 (23kV)…" *Handa et al. Journal of Urology, February 2009The Butterfly's Focus Area

The Duet Magna is equipped with two reflectors and performs Double Shockwave Lithotripsy (DSWL) from these two sources.input:
output:The formation of a distinctive Butterfly Focal Area by DSWL reduces the risk of kidney damage by concentrating pressure on the stone from two distinct angles and spreading the "head and tail" of the shock wave volume.input:
output:The Duet Magna, in fact, approximates the focal volume to a sphere, which is regarded as the optimal focal volume for lithotripsy. The Butterfly Focal Area is superior to the traditional ellipsoid, or "cigar," which only employs 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.
