Transseptal Crossing
The very sharp tip of the SafeSept® requires 75% less force* than a conventional transseptal needle to cross the interatrial septum, making access easier, especially in difficult or previously failed cases, improving the safety of whatever introducer system you are currently using.
The SafeSept is the first significant advance in left atrial access since the Brockenbrough needle. Specifically designed to cross the interatrial septum at the fossa ovalis when supported by a transseptal introducer, SafeSept is a 135cm long, 0.014 inch diameter 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, requiring 75% less force* than a standard transseptal needle. Unsupported by the needle and dilator, the tip of the wire assumes a ‘J’ shape, rendering it incapable of further tissue penetration.
A radiopaque coil along the shaft allows for fluoroscopic visualization of the wire within the left atrium while proximal marker bands help determine the approximate 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.
*Calculated from average transseptal needle and transseptal guidewire puncture forces during in vitro design qualification testing.
Tracking over SafeSept
Features
