Description

The Boston Scientific OverStitch™ Endoscopic Suturing System (ESS-G02-160) represents a significant advancement in flexible endoscopy, allowing physicians to perform advanced endoluminal surgery by placing full-thickness sutures through a dual-channel endoscope. This system enables secure tissue approximation and defect closure that mimics surgical-grade stitching without the need for invasive open or laparoscopic incisions.

By providing the ability to create durable, stable constructs, the OverStitch system expands the therapeutic capabilities of gastroenterologists and bariatric surgeons, facilitating complex procedures such as gastric remodeling and large mucosal defect repairs.


Core Technology: Advanced Endoluminal Suturing

The ESS-G02-160 system is built around a proprietary Curved Needle Design and Knotless Cinch Technology. Unlike traditional methods that rely on surface-level compression, this system utilizes high-strength Polypropylene (non-absorbable) or Polydioxanone (absorbable) sutures.

The technology is optimized for the Apollo OverStitch platform, designed specifically for single-patient use to ensure sterility and peak mechanical performance during every procedure. Its primary innovation is the ability to reload the needle endoscopically while the scope remains in the patient, drastically reducing procedural time.

Mechanism of Action

The OverStitch system operates through a specialized accessory attached to the distal end of a dual-channel endoscope:

  1. Tissue Capture: Using a tissue helix or forceps, the physician draws the target tissue into the path of the curved needle.

  2. Full-Thickness Penetration: The curved needle is deployed to drive the suture through the mucosal, submucosal, and muscularis layers.

  3. Pattern Customization: The operator can choose between running sutures for large areas or interrupted sutures for specific focal points.

  4. Secure Fixation: Instead of manual knot-tying, which is technically difficult in a confined GI lumen, the system uses a mechanical cinch to lock the suture tension instantly and securely.

Primary Applications / Uses

The versatility of the OverStitch ESS-G02-160 makes it an essential tool for several high-complexity GI interventions:

  • Bariatric Procedures: Endoscopic Sleeve Gastroplasty (ESG) and bariatric revision (e.g., outlet reduction after gastric bypass).

  • Defect Closure: Closing large perforations or fistulas that are too expansive for traditional clips.

  • ESD/EMR Reinforcement: Securing the GI wall following Endoscopic Submucosal Dissection or Endoscopic Mucosal Resection.

  • Stent Fixation: Suturing esophageal or biliary stents to the lumen wall to prevent migration.

Frequently Asked Questions

What makes the OverStitch ESS-G02-160 superior to traditional endoscopic clipping?

Traditional clips typically only capture the mucosal layer, which can lead to premature displacement in high-tension areas. The OverStitch system allows for full-thickness suturing that incorporates the muscle layer, providing a significantly more durable and stable closure for large defects or bariatric applications where tissue strength is critical.

Can the OverStitch system be reloaded without removing the endoscope?

Yes. One of the primary design advantages of the ESS-G02-160 is interprocedural reloading. The system allows for the needle to be reloaded under direct visualization while the endoscope remains in situ. This minimizes scope manipulations, reduces the risk of mucosal trauma, and significantly shortens the total procedural time.

Which suture materials are available for the ESS-G02-160 system?

The system supports both non-absorbable Polypropylene and absorbable Polydioxanone sutures. Polypropylene is typically favored for long-term structural constructs like gastric outlet reductions, while Polydioxanone may be utilized for temporary closures where the suture is expected to be absorbed after the tissue has successfully healed.

Is the OverStitch system compatible with standard single-channel endoscopes?

No. To operate effectively, the OverStitch system requires a dual-channel endoscope. This is necessary because the suturing device occupies one channel while the other channel must remain open for secondary instruments, such as a tissue helix or forceps, which are essential for pulling tissue into the needle’s path.

How does the “knotless cinch” work in the ESS-G02-160 kit?

The knotless cinch is a mechanical locking device that replaces traditional hand-tied knots. Once the suture pattern is complete, the physician deploys the cinch over the suture tails and tightens it against the tissue. This provides immediate, high-tension fixation that is faster and more reliable than manual knot-tying in a vacuum-like environment.

What is the packaging configuration for the ESS-G02-160?

The system is typically supplied in boxes containing three (3) individual kits. Each individual kit is designed for a single patient and contains three (3) needles. This configuration ensures that the surgical team has sufficient components to perform complex, multi-stitch patterns without needing to open multiple boxes.
