AcQCross™️ Qx Integrated Transseptal Dilator/Needle

AcQCross™ is an integrated transseptal solution with a zero exchange workflow and pairs with commercially available sheaths for both mechanical and radiofrequency (RF) crossing.


The first and only transseptal access system specifically engineered to pair with commercially available sheaths, including the Medtronic FlexCath Advance™ steerable sheath.

The AcQCross™ system enables a zero exchange transseptal workflow, which adds efficiencies and simplifies left atrial access procedures. AcQCross™ is the only transseptal access system on the market cleared for both mechanical and RF crossing.

Product benefits

Zero exchange workflow

The integrated needle/dilator design removes the need for needle, guidewire, transseptal, and therapeutic sheath exchanges. AcQCross™ helps reduce procedural time of transseptal access by up to 49.9% on average in comparison to traditional mechanical solutions.1,2

Zero sheath exchanges

Dilators compatible with leading industry sheaths eliminate the need for separate transseptal and therapeutic sheaths.
