DynaMesh®

Tailored Implants made of PVDF

DynaMesh®-PRM

DynaMesh®-PRM mesh implants are specially developed for the transobturatoric suburethral sling operation for the treatment of male stress urinary incontinence in light and medium heavy cases. The unique selvedges of DynaMesh®-PRM ensure a simple and atraumatic thread in and adjustment without irritating the surrounding tissue. The dimensional stable textile structure of polyvinylidene fluoride (PVDF) monofilaments with an outstanding effective porosity guarantees an excellent tissue growing-in.


The surgeon selects the method of surgery and final position of the sling depending on her/his preference and the instruments being used. These instruments are procured separately.

Normally, the mesh implant is inserted through a perineal access. The bulbospongiosus muscle is divided in the midline and the urethral bulb is detached from the fibrous nucleus until the urethral bulb is mobile. The tape is inserted transobturatorically with a tunneler. The central mesh part is fixed to the mobile part of the urethral bulb using sutures. Tension on the tape draws the bulb in a cranial direction in the retrourethral space. When the tape is finally in position, a tunnel is formed with an overholt from the perineal wound to the incision site. The ends of the tape are pulled back and cut off at the level of the wound edges. To prevent the tape being displaced in the first weeks of wound healing, the ends of the tape are loosely tied together using a size 2-0 medium-term absorbable suture.

The user must be familiar with the technique involved in implanting a suburethral sling before fitting a DynaMesh®-PRM.

High form stability at defined elasticity

The dynamometry is exactly adjusted to the fields of application. At defined elasticity, they are stable enough to perfectly strengthen the anatomical structures and to shrink minimally only.2)
Especially under tension the high effective porosity persists because the mesh only stretches (in a defined way) lengthwise while width does not change.1) 4)
