Device Description
The transseptal needle kit consists of an outer needle cannula and
an inner stylet. The needle is comprised of flexible thin walled tubing
with an ergonomic hub and stopcock attached to the proximal end.
The stylet consists of a solid wire that when inserted in the needle
protrudes beyond the distal tip of the cannula.
Indications for Use
The transseptal needle is used in conjunction with a transseptal
catheter and/or introducer to create the puncture in the atrial
septum to allow left heart catheterization procedure to occur
through the right atrium.

Left atrial thrombus or tumor
•
Dilated aortic root
•
Continual anticoagulation
•
Inability to lie flat
•
Substantial deformity of the spine or chest

avoid left atrial wall puncture.
•
The transseptal needle should never be advanced until the
catheter is positioned correctly on the atrial septum.
•
Always ensure that the transseptal needle has clearly entered

and fluoroscopy of the needle tip before advancing the
dilator, sheath or catheter.
•
