The Toronto Transseptal Catheter is designed to create a
controlled transseptal puncture through the atrial septum by delivering radiofrequency energy. Physicians have
used the catheter when confronted with a septum that is
thick, fibrotic, aneurysmal, or when the left atrium is very
small. The catheter is more controlled at crossing the
septum than a traditional transseptal needle, and is more
effective than a needle at crossing a difficult septum.
Unlike the transseptal needle, the Toronto Transseptal
Catheter does not rely on mechanical force and is more
flexible than a needle at approaching your puncture site.
• The catheter has a rounded and atruamatic tip
• design that reduces the risk of inadvertent
• mechanical perforation
• The distal end of the catheter shaft is curved so that
• it may be safely advanced into the left side of the
• heart
• The proximal luer lock of the catheter allows for
• diagnostic pressure monitoring that would assist
• with confirming the location of the catheter in the
• heart
• Four side-holes at the distal end of the catheter
• facilitate the delivery of contrast dye as well as with
• monitoring a diagnostic pressure waveform.
• A depth marking on the proximal end of the catheter
• aids in positioning the tip of the catheter in relation
• to the tip of the dilator
