The Integrity bare-metal stent made by continuous sinusoid technology

Area of Science:

• Cardiovascular Devices
• Biomaterials Engineering
• Interventional Cardiology

Background:

• The Driver/Micro-Driver Coronary Stent System is a well-established device.
• Advancements in stent design are crucial for treating complex coronary anatomies.
• Cobalt-chromium alloy offers a favorable combination of strength and biocompatibility.

Purpose of the Study:

• To introduce the Integrity Coronary Stent System, an advanced bare-metal stent.
• To describe the novel continuous sinusoid technology used in its construction.
• To highlight the intended benefits of this new stent design for coronary interventions.

Main Methods:

• The Integrity stent is constructed using continuous sinusoid technology.
• A single thin wire strand is wrapped in a sinusoid configuration around a mandrel.
• Adjacent crowns are fused using laser technology, creating a continuous bending plane.

Main Results:

• The stent exhibits a low-profile and open-cell design.
• Continuous sinusoid technology provides a preferential bending plane for enhanced flexibility.
• The design facilitates easier access and smoother tracking in distal and tortuous vessels.
• Maintained radial strength is a key feature of the stent.

Conclusions:

• The Integrity Coronary Stent System represents an innovative advancement in stent platform design.
• Continuous sinusoid technology offers improved deliverability in complex coronary anatomies.
• This stent platform is poised to support future technologies, including drug-eluting and drug-filled stents.
