BuMA® Biodegradable-Drug-Coating Coronary Stent System 
The BuMA® Drug-Eluting Stent (DES) has an inert eG Coating™ and biodegradable PLGA drug carrier. Together, these two layers form a robust polymer with an elution kinetic that balances the reduction of hyperplasia with the return of a functional endothelium. This early functional healing could result in safer long-term results with the BuMA® DES.
Device Features

Robust polymer coating
Through an electro-chemical process, eG Coating™ is synthesized onto the surface of the stent, creating a filament-like structure that interdigitates into the matrix polymer layer. This technique creates a robust coating integrity that is resistant to flaking, pealing and cracking. 
Lower drug dose and optimized release kinetics
Sirolimus dose and release kinetic were designed to hindering neointimal hyperplasia, while allowing for an earlier return of functional healing.


Rapid absorption of polymer

Following the absorption of the PLGA polymer, only the stent is left behind with eG Coating™. No inflammatory residue remains in the patient after two months.



Flexible stent platform
The overall stent design and helical pattern of the S-Links allow for exceptional flexibility and conformability of the stent.
