Myra™ BMS peripheral stent system

Key feature: hybrid stent architecture

The Myra™ BMS design combines open and closed cells. Closed cells at the proximal and distal ends are intended to provide stable fixation and support at the stent edges, while open cells in the middle segment provide system flexibility when navigating tortuous vascular segments.

This architecture allows mechanical vessel support, controlled deployment, and deliverability in the peripheral vasculature to be combined.

Biomechanics and design features

• Thin scaffold profile: helps reduce vessel wall trauma during implantation while supporting the radial strength of the structure.
• Low recoil: reduced elastic recoil after deployment helps preserve the achieved arterial lumen.
• Longitudinal flexibility: facilitates navigation through anatomically complex segments, including tortuous vessels and access through the aortic bifurcation using a contralateral approach.

Delivery system and ease of use

• Low tip entry profile: the distal tip design, including laser bonding, supports system crossability and trackability.
• Shortened balloon overhang: reduced balloon overhang facilitates access to the target lesion and system advancement.
• Over-the-Wire catheter: the OTW design provides guidewire control and support during advancement of the system to the implantation site.

Visualization and positioning

• Radiopaque markers: integrated markers help position the stent relative to the lesion borders under fluoroscopic guidance.
• Scaffold radiopacity: the stent material provides visualization of the structure during positioning and deployment.

Indications and areas of use

• Treatment of atherosclerotic lesions in peripheral arteries located below the aortic arch.
• Stenting of iliac, subclavian, and other peripheral arteries, if specified in the manufacturer’s instructions.
• Use in patients indicated for percutaneous transluminal angioplasty followed by stenting.

Materials used

• L605 cobalt-chromium alloy: scaffold material that combines mechanical strength, biocompatibility, and radiopacity.
• Platinum-iridium alloy: used for positioning markers and visualization under fluoroscopy.
• Semi-compliant polyamide: balloon material providing controlled stent deployment.

System components

• Balloon-expandable peripheral stent.
• Balloon dilatation delivery catheter.
• Integrated radiopaque positioning markers.

Certification and safety

• The device is supplied sterile and sterilized with ethylene oxide, if confirmed by the manufacturer’s documentation.
• Non-pyrogenic status and material biocompatibility should be stated in accordance with the manufacturer’s instructions.
• The system is intended for single use.
• The size range allows stent configuration to be selected according to vascular anatomy and lesion parameters.
• CE marking and compliance with applicable medical device safety requirements should be confirmed by current manufacturer documentation.
