Device Description
The transseptal needle kit consists of an outer
needle cannula and an inner stylet. The needle
is comprised of exible 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.
Contraindications
• Left atrial thrombus or tumor
• Dilated aortic root
• Continual anticoagulation
• Inability to lie at
• Substantial deformity of the spine or chest
• Marked atrial enlargement
• Distorted anatomy due to congenital heart
disease
• Previous intra-septum patch
Warnings
• For single use only. Do not reuse, reprocess or
resterilize. Reuse, reprocessing or resteriliza-
tion may compromise the structural integrity
of the device and/or lead to device failure
which in turn may result in patient injury,
illness or death. This single-use product is not
designed or validated to be reused. Reuse may
cause a risk of cross-contamination, aect the
measurement accuracy, system performance,
or cause a malfunction as a result of the prod-
uct being physically damaged due to cleaning,
disinfection, re-sterilization, or reuse.
• Only those physicians who specialize in the
practice of invasive cardiology techniques
should use this device. The device should be
restricted for use by those specialists trained
to perform transseptal procedures.
• Maintain continuous pressure monitoring
and repeated biplane uoroscopy during
positioning.
• Caution should be used in patients with small
left atrium, to avoid left atrial wall puncture.
• The transseptal needle should never be
advanced until the catheter is positioned
correctly on the atrial septum.

Transseptal Needle and Stylet Set
Directions for Use
• Always ensure that the transseptal needle
has clearly entered the left atrial cavity by
conrming distinct left atrial pressure and u-
oroscopy of the needle tip before advancing
the dilator, sheath or catheter.
• Do not remove a dilator, sheath or catheter
that has been inadvertently advanced into the
pericardial space until the patient is in surgery.
• Do not reuse this device. The device must
be discarded after one use using acceptable
medical practices and applicable local, state
and federal laws and regulations.
• Follow instructions accompanying the trans-
septal introducers.
Precautions
• Store in a cool, dark and dry place.
• Inspect all components prior to use.
• If resistance is met while advancing or with-
drawing the introducer or guidewire, uoros-
copy should be used to determine the cause.
• Prior to use, ensure the appropriate catheter is
being used with the transseptal needle.
Adverse Events
In addition to the complications associated with
any cardiac catheterization, the following could
occur during a transseptal catheterization:
• Inferior vena cava puncture
• Aorta puncture
• Atrial free wall puncture
• Coronary sinus puncture
• Arterial embolism from thrombus at the
puncture site
• Tamponade
• Residual atrial septal defects
• Atrial arrhythmia
Directions for Use
1. To determine the size and location of the left
atrial septum, it may be helpful to perform
right side angiography.
2. Thoroughly ush the transseptal needle.
3. Inspect all components prior to use for integ-
rity and appropriateness for the particular
procedure.
4. The transseptal needle/stylet set is advanced
through the transseptal catheter and/or intro-
ducer until the tip of the needle is just within
the catheter. Note: Ensure the transseptal
needle is free to twist and/or rotate without
resistance, as it is advanced to this position.
5. Retract the stylet prior to puncturing the inter-
atrial septum.
6. The tip of the transseptal needle is positioned
against the interatrial septum.
7. The transseptal needle is advanced through
the septum into the left atrium once the cor-
rect location is conrmed using uoroscopy
(preferably biplane).
8. The successful puncture into the left atrium is
conrmed by observing a left atrial pressure
tracing. If an incorrect pressure tracing is
observed, a small amount of contrast media is
injected to identify the positioning.
9. The transseptal catheter is advanced over the
transseptal needle into the left atrium.
10.
The transseptal needle is slowly removed.
