Clinical Performance & Studies

NeoVas RCT Study

The study enrolled 560 subjects in 33 centers. Test group (NeoVas): 278 cases; Control group (Xience stent): 282 cases. Primary endpoint: late lumen loss in one-year follow-up.

NeoVas OPC Study

Enrolled 1103 subjects across 45 centers. Results demonstrate that NeoVas bioresorbable stent has a favorable safety profile compared to the first-generation BVS, with significantly decreased clinical event rates.

Imaging & Absorption Study

OCT data at 3 years shows vessel vasomotor function restoration. Most of the stent was successfully degraded and absorbed after 3 years, maintaining a favorable level of blood supply.

Standardized PSP Operations

💡 Why PSP is Critical?

Standardized PSP (Pre-dilatation, Sizing, Post-dilatation) operation ensures proper stent apposition and excludes vascular dissection. Failure to perform PSP can increase the risk of stent thrombus and TLF (Target Lesion Failure).

Frequently Asked Questions

What is the NeoVas stent made of?

The NeoVas stent platform is made of fully degradable poly(L-lactide) (PLLA), and the drug coating is made of fully degradable poly(D,L-lactide) (PDLLA).

How long does it take for the stent to be absorbed?

Clinical imaging studies show that most of the NeoVas stent is degraded and absorbed by the body after approximately 3 years.

What drug is used in the NeoVas stent?

The stent uses classical Sirolimus at a dose of 15.3ug/mm to inhibit the proliferation and migration of smooth muscle cells.

What is the significance of the PSP operation?

PSP stands for Pre-dilatation, Sizing, and Post-dilatation. It is a standardized procedure essential to ensuring proper stent apposition and reducing the risk of clinical events like stent thrombus.

Does the vessel function return to normal after implantation?

Yes, imaging studies indicate that vessel vasomotor function is restored after 3 years, which is superior to the permanent presence of traditional metal stents.

Is the NeoVas stent as safe as traditional metal stents?

The NeoVas RCT study concluded that the bioabsorbable stent shows equal safety and effectiveness compared to high-end metal stents like Xience.
