Use of the mini OTSC® System Set

The new compact design of the mini OTSC® System allows the use of the application technique of the proven OTSC® System for small lumen or difficult to access lesions in the gastrointestinal tract.

The mini OTSC®

The mini OTSC® System Set consists of an applicator cap with a mounted clip, thread, thread retriever and a hand wheel for clip release.

The mini OTSC® clip is delivered by means of an applicator cap mounted to the tip of endoscopes. By turning the hand wheel, the white application ring is pulled towards the distal end of the cap and the clip is released.

The mini OTSC® clip for flexible endoscopy is a superelastic Nitinol® device for compression and approximation of tissue in the digestive tract.

Based on its unique design the clip closes itself and firmly anchors the tissue to be compressed for hemorrhage or closure of a GI organ wall lesion. Due to its smart material properties, the mini OTSC® clip delivers constant force at the application site securing the therapeutic effect. The mini OTSC® clip is made of a biocompatible and MR conditional material and can remain in the body as a longterm implant.

Dimensions and specifications

Features and sizes of the applicator caps:

The mini OTSC® applicator cap is suitable for endoscopes with a diameter from 8.5 – 9.8 mm and has a cap depth of 3 mm.

Features of the clips:

The mini OTSC® Clip is a smaller version of the OTSC® Clip 11 and is available in one size with two different shapes of teeth (types a and t).

Application of the mini OTSC® System Set

Hemostasis with suction technique

In most GI bleeding situations, tissue can be mobilized and securely pulled inside the application cap by simply applying endoscopic suction. Once the target tissue is captured inside the cap, hemostasis is achieved by turning the handwheel to release the OTSC® clip around the captured tissue.

Hemostasis with anchor technique

In cases of fibrotic or hard tissue (e.g. callous ulcers) or tangential application, the OTSC® Anchor can be valuable in precisely aligning target tissue with the cap opening and keeping it fixed during clip release. It may not always be possible to manipulate fibrotic tissue fully inside the cap. However, it is sufficient to pull the tissue firmly to the rim of the cap with the OTSC® Anchor, then apply the clip. The clip “jumps” slightly forward upon release and grasps the tissue in front of the cap.

Blutstillung mit dem OTSC System und Ankertechnik Schritt 1

Position the OTSC® Anchor and fix the tissue

Blutstillung mit dem OTSC System und Ankertechnik Schritt 2

Align the OTSC® cap to the lesion by pulling the anchor and advancing the endoscope

Blutstillung mit dem OTSC System und Ankertechnik Schritt 3

Mobilize the tip of the OTSC® Anchor shaft into the cap; anchor spikes may remain external; release the OTSC® clip

Blutstillung mit dem OTSC System und Ankertechnik Schritt 4

After clip application, detach the OTSC® Anchor from the tissue

Fistula closure

Fistelverschluss mit dem OTSC Schritt 1

Target fistula opening, position the OTSC® Anchor and fix tissue

Fistelverschluss mit dem OTSC Schritt 2

Align OTSC® cap to the fistula opening by pulling the anchor and advancing endoscope

Fistelverschluss mit dem OTSC Schritt 3

Mobilize tip of OTSC® Anchor shaft into cap; anchor spikes may remain external

Fistelverschluss mit dem OTSC Schritt 4

Apply clip; release OTSC® Anchor from tissue
