The Solitaire™ device has become the most-published stent retriever with over 200 publications demonstrating clinically proven, tried-and-true performance.1,2
The Solitaire™ X device has a unique parametric design that has been fundamental to the generations of the Solitaire™ portfolio.

  • This overlap design allows the stent to expand and compress in the vessel during deployment and retrieval. 
  • The distinctive, evenly spaced platinum markers enable accurate alignment and feedback during the procedure with a three-dimensional perspective.3* 

Product details

Conform to anatomy with wall apposition and dynamic clot integration4,5*

  • Maintains consistent cell size and structure over varying vessel diameters6*
  • Provides multiple planes of contact to integrate with the clot, even double layering in smaller vessels7*

Percent overlap by vessel diameter5*

Visualize accuracy with real-time imagery

  • Meaningful visibility with real-time visualization of the radiopaque markers
  • Evaluate clot composition through body marker integration into the clot
    • Visualize the expansion and compression of the stent to help identify clot characteristics8

Encapsulate the clot without damaging the wall9†

Differentiated radial outward force promotes clot and vessel wall contact during retrieval with the optimal amount of radial force.10*

Solitaire™ X differentiated outward force - 3x20

Solitaire™ X differentiated outward force - 4x40

Solitaire™ X differentiated outward force - 6x40

Clinical evidence

Optimize outcomes by minimizing the number of passes11-13

A large real-world patient cohort demonstrated a first pass effect (FPE) rate of 40.5% and a modified FPE (mFPE) rate of 58.9% across patients treated with the Solitaire™ device.14‡

Achieve the clinical outcomes you expect

A large real-world patient cohort demonstrated the following results with the Solitaire™ device.15
