Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients referred for diagnostic or interventional catheterization via radial or cubital approaches.
✕Probably not a fit
Patients with local conditions like hematomas or pseudo-aneurysms that prevent radial or cubital access may not benefit from this study.

What this trial studies
This observational study aims to evaluate the effectiveness and safety of the Terry2™ band in achieving non-occlusive hemostasis of the radial artery after transradial catheterization. The study focuses on improving patient comfort and minimizing the risk of radial artery occlusion (RAO), a common complication that can limit future access to the artery. By applying simultaneous pressure to both the radial and cubital arteries, the Terry2™ band aims to reduce the incidence of RAO to less than 2%. The study will involve patients undergoing diagnostic or interventional catheterization through radial or cubital approaches.
Why it matters
Potential benefit: If successful, this approach could significantly reduce the risk of radial artery occlusion, improving future access for catheterization and surgical procedures.
How similar studies have gone: While the concept of non-occlusive hemostasis has been explored, the use of the Terry2™ band represents a novel approach that has not been widely tested in clinical settings.

Inclusion Criteria: * Any patient referred for diagnostic or interventional catheterization through radial or cubital approach Exclusion Criteria: * Unable to understand the study design and sign an informed consent * Unable to receive antiplatelet therapy with aspirin and/or clopidogrel-prasugrel and/or ticagrelor and intravenous anticoagulant treatment with heparin or bivalirudin * Presence of any local conditions like hematoma or pseudo-aneurysms precluding radial or cubital access. * Presence of PPG while simultaneously compressing the radial and cubital arteries (due to collateral branches or interosseous artery), which prevents the establishment of non-occlusive hemostasis with the Terry2(TM) band.
