Purpose-built

Designed for the Challenges of
Below-The-Knee (BTK) Interventions

Every aspect of the MicroStent™ Peripheral Vascular Stent System has been engineered to address the unique clinical demands of below-the-knee anatomy—balancing flexibility, visibility, deliverability, and vessel support to help physicians treat complex lesions with confidence.

Purposely Designed Benefit
48 woven strands, self-expanding nitinol stent design Maximizes the flexibility and conformability of the stent in complex anatomy
Provides permanent, crush-resistant scaffolding Improves luminal diameter in the treatment of ischemia in the lower leg1
4 Fr Introducer Sheath compatibility Low profile minimizes vessel access trauma and traverses complex distal anatomy below-the-knee, from antegrade, retrograde, or pedal approach2
Simple pin & pull designed delivery system Allows for precise control for delivery of the stent
Radiopaque shaft markers Aides in properly placing the stent at the desired anatomic location
0.014” Guidewire compatible Smaller guidewire compatibility may reduce wire exchanges with the 0.014” platform
40 cm or 120 cm shaft length Different shaft lengths allow for optimal device selection for antegrade or retrograde access
Wide range of stent sizes to accommodate targeted anatomy Sizes are specifically designed for the below-the-knee vasculature

The Peripheral Vascular Stent System

Working together below the knee

Below-the-knee vessels are small, tortuous, and unforgiving for rigid implants. The MicroStent™ System’s woven architecture was built around three requirements that matter most in this anatomy.

Flexibility & conformability

The low profile system minimizes vessel access trauma and easily navigates complex distal anatomy below-the-knee, from antegrade or retrograde approach. The self expanding, woven nitinol implant design maximizes flexibility and comfortability without compromising performance.

Visibility

Nitinol construction with a platinum core in each strand for visibility across imaging modalities, as well as radiopaque shaft markers to assist in precise placement.

Scaffolding

A permanent scaffold with low chronic outward force and high radial resistive force, leaving a durable, long-term repair in challenging clinical scenarios.

Technology

48 Strands woven nitinol design
0.014" OTW guidewire compatible
4 Fr Introducer Sheath compatibility
40 / 120 cm shaft length options

Unique Engineering

Platform architecture, visibility, vessel preservation and mechanical performance

Low-profile delivery system designed to reach distal anatomy. Supports both antegrade and retrograde access across the complete product portfolio.

Platform architecture

48-Strand Braided Nitinol Design

Continuous braided architecture designed to conform to vessel anatomy while maintaining consistent wall apposition

Visibility

Platinum-Core Technology

Integrated platinum core in each ultra-low profile, round nitinol strands (<50 microns)

Vessel preservation

Low Chronic Outward Force (COF)

Applies gentle, continuous vessel support designed to minimize chronic vessel wall stress.3

Mechanical performance

Optimized Radial Resistive Force (RRF)

Engineered to resist compression while maintaining long term support in highly complex vessel anatomy.3
