Easing left-side access for electrophysiology


The SafeSept™ Transseptal Guidewire, is the first significant advance in left atrial access since the Brockenbrough needle.

The SafeSept is a 0.014 inch diameter, 120cm long nitinol guidewire specifically designed for transseptal puncture. After the transseptal dilator has “tented” the fossa ovalis, effortless advancement of the SafeSept tip perforates the membranous fossa. Unsupported by the needle and dilator, the tip of the wire assumes a ‘J’ shape, rendering it incapable of further tissue penetration hence removing the risk of perforation.


A radiopaque coil on the shaft allows for visualization of the wire within the left atrium and proximal white printed markers help approximate the location of the SafeSept tip in relation to the tip of the needle. The transseptal needle, dilator and sheath are then advanced “over the wire” into the left atrium with virtually no possibility of aortic or pericardial perforation.

The SafeSept Transseptal Guidewire is part of a complete line of implantable device therapy products and accessories from Pressure Products.
