DynaMesh®-IPST
DynaMesh®-IPST, DynaMesh®-IPST visible, DynaMesh®-IPST-D visible, DynaMesh®-IPST-R and DynaMesh®-IPST-R visible implants are intended for the surgical treatment of parastomal hernias, and the prevention (not DynaMesh®-IPST-R or DynaMesh®-IPST-R visible) of parastomal hernias following ostomy surgery, and permanently bridge and reinforce the soft tissue of the abdominal wall in the area of the stoma.

3D Funnel
The device has a passage point with a connected funnel for the passage of the intestine. The base area of the device must be positioned in contact with the tissue, as flat and smooth as possible, with the funnel pointing in the direction of the abdominal cavity.
When selecting the device, the diameter of the passage point should be chosen so that the intestine is tightly sheathed in the funnel.
Prefabricated Slit & Smooth Warp-Knitted Selvedges
Only DynaMesh®-IPST-R and DynaMesh®-IPST-R visible have a one-sided slit along the funnel and the base area (mesh flaps), starting from the passage point.
During positioning, the tight sheathing of the intestine in the funnel is achieved through appropriate overlapping of the mesh flaps with non-absorbable closure of the aperture.
Prevention and Repair of Parastomal Hernia
The diameter of the mesh funnel should be chosen so that the intestine is tightly sheathed. In repair, sufficient defect overlap and coverage of the base of the passage is necessary. When using DynaMesh®-IPST-D visible, attention must be paid to the side specificity (left-sided/right-sided stoma).

Repair of Parastomal Hernia
With DynaMesh®-IPST-R and DynaMesh®-IPST-R visible, a tight sheathing of the intestine is achieved by a suitable overlap of the mesh flaps with non-absorbable closure.

DynaMesh®-IPST implants (1)-(5) must be inserted via an appropriate minimally invasive or open approach and must be placed intraperitoneally.
DynaMesh®-IPST implants (1)-(5) have a parietal side and a visceral side. The parietal side is identified by green filament ends and consists of PVDF on the surface and a small proportion of PP, whereas the visceral side consists of PVDF on the surface.
When using DynaMesh®-IPST-D visible (3), attention must be paid to the side specificity (left-sided/right-sided stoma), through which a particularly large overlap in a cranial as well as in a medial direction is ensured.
When positioning DynaMesh®-IPST-R and DynaMesh®-IPST-R visible (4) (5), the tight sheathing of the intestine in the funnel is achieved through appropriate overlapping of the mesh flaps with non-absorbable closure of the aperture.
