Everything you knew about bioabsorbable polymer stents has changed.

MiStent is the only stent which is tailored to the vessel response, optimising patient outcomes by ensuring sustained drug release long after its polymer coating is absorbed, thanks to its unique crystalline drug release technology.

Unique Crystalline Drug Delivery

MiStent SES delivers sirolimus, in a crystalline form, to the tissue. This unique method of delivery allows for a sustained drug presence that is maintained after the polymer is absorbed.

  • Gradual, Linear and Long-Term Elution Profile


    Unique to MiStent SES sirolimus is maintained in a microcrystalline matrix and elution is sustained up to 9 months, as opposed to a conventional DES which utilises an amorphous form of drug and a much shorter elution period.


    *Tissue Assay is unable to differentiate between crystalline and dissolved drug, therefore this chart is only an estimation and is representative.

  • Rapid Polymer Absorption with Sustained Drug Presence

  • Thin Strut Design


    *Adapted from Dawkins, K., oral presentation at TCT 2014 and relevant product websites accessed in January 2015. 

  • Outstanding Acute Performance


    *Deliverability is defined as 100 / the average of the forces required to Insert, Track, Retract and Withdraw the stent delivery catheter through a 90 angle, a tortuous anatomy model and a guide catheter.

  • Rapid Strut Coverage


    Uncovered struts are predictive of late stent thrombosis1
