NCT04966273

Brief Summary

Biosensors, the Sponsor would like to determine if the Biosensors Microcatheter is safe and effective in treating patients with CTO by assessing a composite of in-hospital cardiac death or myocardial infarction and device success (defined as successfully facilitate placement of a guidewire beyond the occluded coronary segment), respectively.

  • Safety: Percentage of patients with composite of in-hospital cardiac death or myocardial infarction.

    Composite of in-hospital cardiac death or myocardial infarction.

    Follow-up only up to hospital discharge or 7 days maximum post procedure, whichever comes first.

Secondary Outcomes (3)

  • Percentage of patients with technical success

    Follow-up only up to hospital discharge or 7 days maximum post procedure, whichever comes first.

  • Percentage of patients with procedural success

    Follow-up only up to hospital discharge or 7 days maximum post procedure, whichever comes first.

  • Percentage of patients with crossing success

    Follow-up only up to hospital discharge or 7 days maximum post procedure, whichever comes first.

Other Outcomes (2)

  • Percentage of patients with device-related perforation

    Follow-up only up to hospital discharge or 7 days maximum post procedure, whichever comes first.

  • Percentage of patients with device failure

    Follow-up only up to hospital discharge or 7 days maximum post procedure, whichever comes first.
