UNITY-B
Endoscopic Balloon Expandable Biodegradable Stent System
added benefit of biodegradation
to minimize complications
The UNITY-B Endoscopic Balloon Expandable Biodegradable Stent System is designed to replace self-expanding metallic stents (SEMS) with the added benefit of biodegradation to minimize the complications associated with metal stents such as perforation, stent-in-growth, stent-over-growth and the inability to remove metal stents.
UNITY-B is a hybrid biodegradable stent that:
Functions like a metallic stent
Can be used in non conforming strictures
Can be over-dilated without fracturing
Has minimal recoil and foreshortening
Does not require in advance preparation of the stricture
Can be placed with the same traditional approach used for a normal metallic or DES stent
Can be easily produced in a wide range of sizes

| Characteristics | UNITY-B | OmniLink |
|---|---|---|
| Crossing Profile (mm) | 2.20 – 2.40 (mean 2.30) | 2.22 – 2.27 (ø10 mm) |
| Foreshortening, max at NP (%) | 0.9% (RBP) ø10 mm | 2.30% (RBP) ø10 mm |
| Maximum Recoil of the expanded stent at NP (%) | 3.1% (NP) ø10 mm | 3.14% (NP) ø10 mm |
*Unity vs Main Competitor
Enhanced features:
Initial surface degradation allows for bile flow and “self-cleaning” of biofilm
Minimizes stent-in-growth
Minimizes stent-over-growth
Minimizes stent perforation (no COF)
The issue of stent removal is eliminated
