🔍 Product Description

Nanoporous cavities on strut abluminal surface functioning as drug carrier to ensure the firm adhesion.
Vacuum drug coating technology ensures complete drug dosage and coating stability.
Post-treatment after drug loading helps with sustained drug release.

Soft tapered tip provides smooth transition from guidewire to balloon catheter and excellent crossability.
Short shoulder design at both ends of the balloon ensures the accurate dilation to the lesion, and reduces the damage to normal vessel next to the lesion.
Patented hydrophilic coating on distal shaft provides outstanding pushability.

Safety & Efficacy Profile:

Polymer-free design significantly reduces the inflammatory response after stent implantation to guarantee long-term safety.
Polymer-free design facilitates earlier endothelialization which significantly shorten the DAPT time.
The rough strut surface helps with earlier and easier endothelialization to reduce the risk of thrombosis.

Frequently Asked Questions

Q1: What makes the Nano+ stent "Polymer-Free"? The Nano+ stent utilizes nanoporous cavities on the abluminal surface of the strut as a drug carrier, eliminating the need for a traditional polymer coating. This significantly reduces inflammatory responses.

Q2: How does the vacuum drug coating technology benefit the patient? It ensures complete drug dosage and enhances coating stability, providing a more reliable and controlled drug release to the lesion site.

Q3: Can this stent shorten DAPT time? Yes. The polymer-free design facilitates earlier endothelialization, which can significantly shorten the required Dual Antiplatelet Therapy (DAPT) duration compared to traditional DES.

Q4: What are the primary materials used in the stent? The stent is constructed from high-quality 316L Stainless Steel with a nanoporous drug carrier design and a patented hydrophilic coating on the distal shaft.

Q5: What is the drug release period for the Sirolimus coating? The system is designed for a 90-day drug releasing period to effectively inhibit SMC migration and proliferation while ensuring vessel healing.
