TECHNOLOGY OF ESWT WOUND THERAPY

UNIQUE IN WOUND THERAPY – THE USE OF LINEAR FOCUSED SHOCKWAVES
Richard Wolf GmbH and ELvation Medical GmbH have developed a new and unique technology: a linear, focused shockwave. The aim was to create a shockwave that could be applied much more uniformly and effectively compared to conventional point-focused shockwaves.  Gel pads are used to adjust the penetration depth to between 0 and 20 mm, ensuring that the acoustic field is optimally adapted to the respective dermatological application.

The focal zone of a piezo shockwave is the area (-6dB zone) in which the maximum positive peak pressure drops to half of peak pressure. Shockwaves show a 3-dimensional spatial distribution along the x, y and z axes. This focal zone can be adjusted to precisely target the treatment area as this also minimizes trauma to adjacent tissue. The focal zone of a linear focused piezo therapy source (FBL10x5G2, intensity 10) has a 3-dimensional volume of 46 mm x 20 mm x 4 mm. Because of the direct focusing technology of piezo shockwave systems, the size of the focal zone barely changes, even when the intensity setting is adjusted.
The penetration depth of the focal zone is preselected using gel pads of different thicknesses. A special feature of linear focused shockwaves is the option to select a “0” gel pad. Half of the focal zone remains within the gel pad, ensuring that peak pressure in the focal center is precisely at skin level.
