Unmet Clinical Need

Luminal diseases can lead to blockages in blood vessels or tubular structures in your body. Metallic and synthetic-covered stents are used to open these structures; however, your body may recognize the implants as foreign materials and respond with a negative reaction. This rejection leads to numerous complications including restenosis, inflammation, infection, allergic responses, scarring and thrombosis.

Amnion-covered stents may alleviate the complications associated
with metallic and synthetic-covered stents.


AMStent™ Solution

The AMStent™ is the first stent fully covered in amnion tissue, a proven biomaterial with regenerative properties. It has the promise to keep lumens open longer with potentially fewer complications than bare metal stents, covered stents or drug-eluting stents.

A Proven Biomaterial that Promotes Healing

More than 100 years of clinical history with a growing list of applications

  • Wound and burn management
  • Ocular tissue reconstruction
  • Spine surgery adhesion barrier
  • Reconstructive and plastic surgery

Favorable biologic properties and safety profile

  • Supports natural endothelialization and the regeneration of healthy tissue
  • Anti-inflammatory property minimizes the foreign body response
  • Anti-microbial property reduces the risk of infection
  • Anti-fibrotic property minimizes obstructive granuloma formation
  • Anti-thrombotic property minimizes thrombus formation


A Platform Technology that Solves Challenges in Luminal Disease Treatment

Designed to restore and maintain long-term lumen patency

  • The AMStent™ combines the regenerative properties of amnion tissue and mechanical properties of a stent frame

Thin, compliant amnion allows for stent delivery through a smaller catheter

  • A 10 mm AMStent™ can be delivered using an 8 Fr catheter, unlike other covered stents of that size which require an 11 Fr catheter

A Tracheobronchial Stent Designed for
Palliative Care to Improve Quality of Life

The AMStent™ is fully covered in amnion tissue, which provides a bed for natural endothelialization to support the regeneration of healthy tissue

  • Healthy re-epithelialization re-establishes mucociliary escalation and minimizes migration

Complication/reintervention rates for current metallic tracheal stents range approximately 20-40%1-10

  • Anti-microbial and anti-inflammatory properties of the amnion tissue may minimize complications and mitigate reintervention
