Study summary

This Post-Approval Study is a single arm, prospective, multi-center, open-label study of patients treated with the Renata Minima Stent System in the United States. The objective of the study is to continue the assessment of device performance and capture outcome data on use of the device in real-world use.

Read the detailed description

A minimum of 100 subjects will be enrolled. Follow-up will occur immediately after the initial implant procedure, at subsequent re-dilation procedures, annually, and at any additional standard of care follow-up visits (determined by the implanting physician) through 5 years post-implant. Data collected at each follow-up will be used in analysis. This study will monitor key data points related to the device and procedure.

Study population

Patients treated with the Renata Minima Stent System in the United States

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • The subject's legally authorized representative has been informed of the nature of the device treatment, agrees to its provisions, and has provided written
  • Indicated for treatment with the Minima Stent System per the IFU.

Exclusion criteria

Exclusion Criteria:

  • Active bloodstream infection requiring antibiotic therapy within 3 days prior to stent implantation
  • History of or active endocarditis (active treatment with antibiotics) within 180 days prior to stent implantation
  • Aortic or pulmonary artery aneurysm in the location targeted for treatment
  • Body weight \< 1.5 kg
  • Anatomic location of lesion judged by the investigator to not lend to the safe placement of a stent
  • Target vessels larger or smaller than the Minima System balloon size ranges
  • Known genetic syndrome known to be associated with vasculopathies such as but not limited to Williams syndrome, Loeys-Dietz syndrome, etc
  • Clinical scenario requiring that more than one vessel needs stent implantation at the time of the trial procedure.
  • Currently participating in an drug study or another device study
  • Major or progressive non-cardiac disease resulting in a of less than six months
  • Known to aspirin or heparin and cannot be treated with other antiplatelet and/or antithrombotic medications
  • Known hypersensitivity to cobalt-chromium or contrast media that cannot be adequately premedicated
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Rate of Acute Device Success

    Rate of Acute device success as defined by: * Stenosis relief, defined by stent outer diameter ≥ 75% of the normal surrounding vessel immediately after deployment. * Freedom from open surgical intervention required to treat Minima Stent dysfunction at implantation

    Time frame: End of Procedure (Following Implantation of the Stent)

  2. Rate of Participants with Freedom from procedure- or device-related SAEs

    Rate of Participants with Freedom from procedure- or device-related SAEs resulting in an event listed below: * Death * Cardiac arrest and/or emergency ECMO cannulation * Stroke * Limb loss * Vessel dissection of target lesion * Device thrombosis/occlusion * Cardiac perforation requiring percutaneous or open surgical intervention * Persistent cardiac arrhythmia requiring a pacemaker

    Time frame: Immediately after Postoperative

Secondary outcomes

  1. Rate of Successful Stent Re-Dilation and Peak-to-Peak Pressure gradient

    * Peak-to-peak pressure gradient (ventricle to arterial or arterial to arterial) \< 20 mmHg after stent placement, in treatment of Aortic Coarctation, when applicable. * Successful stent re-dilation (when indicated) at recatheterization, defined as angiographic improvement of stenosis to \>50% of the normal surrounding vessel. * Maintenance of stented vessel diameter ≥ 50% of post implant diameter at the time of re-dilation (pre re-dilation).

    Time frame: During and end of procedure

  2. Rate of Participants with Freedom from Stent Migration/Embolization, procedure- or device- related SAEs, and non-elective stent explant

    * Freedom from intraprocedural stent movement to non-intended location during the procedure. * Freedom from postprocedural stent embolization or migration * Freedom from stent fracture that led to reintervention * Freedom from non-elective Minima Stent explant * Freedom from procedure- or device-related SAE during re-dilation that results in the following: * Death * Cardiac arrest and/or emergency ECMO cannulation * Stroke * Limb loss * Vessel dissection of target lesion * Device thrombosis/occlusion * Cardiac perforation requiring percutaneous or open surgical intervention * Persistent cardiac arrhythmia requiring a pacemaker

    Time frame: During and at end of procedure

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 23, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
