OTSC® application aid for better approximation of tissue especially when indurated .
Use of the OTSC® Anchor
The OTSC® Anchor can be used for better approximation of tissue especially when indurated (e.g. fistulae, chronic ulcer). It also facilitates targeting of lesions, e.g. in the treatment of hemorrhage, the OTSC® Anchor allows precise alignment between the target tissue and the applicator cap.

The OTSC® Anchor is available in two versions and lengths:
- The OTSC® Anchor has a flexible shaft length of 165 cm
