A novel vascular Endostapling system offers a new method for securing endografts. This technology may prevent endograft migration and treat endoleak, enhancing aortic repair outcomes.

Area of Science:

  • Vascular surgery
  • Medical device innovation
  • Endovascular techniques

Background:

  • Endovascular aneurysm repair (EVAR) is a common treatment for abdominal aortic aneurysms.
  • Endograft migration and endoleak remain significant complications after EVAR.
  • Secure fixation of endografts is crucial for long-term repair durability.

Purpose of the Study:

  • To introduce and describe a novel vascular Endostapling system.
  • To present the mechanism and potential applications of this new device.

Main Methods:

  • The vascular Endostapling system is delivered via a 13F sheath through the femoral artery.
  • An optical fiber and Endostaple penetrate the endoprosthesis and aortic wall at targeted locations.
  • Upon optical fiber withdrawal, the Endostaple forms a suture-like structure, with tissue ingrowth enhancing stability.

Main Results:

  • The Endostaple functions as a through-and-through wire suture after deployment.
  • The coiled coil mechanism is expected to increase in security and stabilization with tissue ingrowth.
  • The system allows for precise placement of fixation points.

Conclusions:

  • Vascular Endostaples show promise in preventing endograft migration.
  • The system may be effective in treating endoleak at the aortic neck-proximal endograft interface.
  • This technology represents a potential advancement in securing endovascular repairs.
