ReThink Short DAPT

The world’s first and only non drug-eluting, nanocoated coronary stent that allows physicians to safely and effectively treat patients with short, 1-month DAPT.1

Faster, Higher-Quality Healing than Market Leading DES4‡

Strut Coverage at 14 Days
COBRA PzF NCS demonstrated near complete strut coverage compared to SYNERGY™ and XIENCE™ in preclinical evaluations.3
99% Strut Coverage at 14 Days
Polyzene-F NanoCoating
The ultra-pure PzF polymer possesses high molecular weight, elasticity and biocompatibility.

Polyzene-F: A Distinctly Superior Nanocoating

COBRA PzF NCS is coated with Polyzene-F (PzF), a biomimetic, nano-thin surface coating that acts as a barrier between the device, intimal surface, and circulating elements in the blood.

About PzF

Individualized Antiplatelet Therapy (DAPT)

Finding the right DAPT balance is critical to reducing complications. COBRA PzF NCS is a new choice of stent that allows physicians an individualized approach to safely and effectively treat their patients who may benefit from a minimum of 1-month DAPT2 and is being studied with even shorter, 14-day DAPT in the COBRA REDUCE IDE trial.§

Press Release

San Antonio, TX – June 1, 2020

CeloNova Announces Enrollment Completion of World’s First Randomized Control, 14-Day DAPT Trial

The COBRA REDUCE randomized control trial is a first-of-its-kind study designed to evaluate ultra-short DAPT in PCI patients at high bleeding risk with COBRA PzF NCS with 14-day DAPT compared to drug-eluting stents with 3 or 6 months DAPT.
