Colonic and Rectal Stents OTW

The OTW (over-the-wire) colonic and rectal stents of Micro-Tech have a particularly high positional stability. In the OTW colonic stents this is achieved via a square-edged transition, situated near each end of the stent. This anchors the stent inside the lumen and adapts it optimally to the anatomy and peristalsis of the colon. In contrast, rectal stents are less stimulating and hence more “ball-shaped”, ensuring the patient experiences less irritations in this sensitive area, therefore increasing quality of life.

The partially sheathed OTW colonic and rectal stents produce very high radial forces, therefore they should be placed into straight segments of the colon, and not into the bent segments, such as the right and left flexure of the colon.

Successful in Practical Use

The stents are successful in application through their opening performance and distinctive end shape this allows the stent to be firmly anchored in the semilunar folds of the colon. In order to facilitate orientation during deployment, the stents have additional X-ray markings at all significant points.

Positionally Stable in All Sizes

Colonic and rectal stents are available in lengths of 80 mm and 100 mm. Stents for patients who have undergone anastomosis have a length of 60 mm. You can choose between non-covered, partially covered and end-to-end covered versions.
