CAUTION: Use only an insertion needle
provided by Boston Scientific. Other
needles may damage the lead. The
stamped number "14" on the needle
hub (or the triangle on the hub of the
curved Epimed needle, sold separately)
corresponds to the orientation of the
bevel, which must face up. Turning the
bevel down may result in lead damage.
Note: Engaging the dermis can be
prevented by facing the needle bevel
down from the dermal interface and
pinching the skin.
CAUTION: If electrodes are too close
to (or through) the fascia, the patient
may experience painful direct muscle
stimulation. If they are too superficial, the
risk of electrode erosion is increased.
3. Remove the needle stylet from the
insertion needle.
4. Slowly introduce the lead, with lead stylet,
through the insertion needle. Advance to
the tip of the needle.
5. OPTIONAL. If exchange of the lead stylet
is desired, carefully pull out the existing
stylet and insert the preferred stylet.
While inserting the stylet into the lead,
if resistance is encountered, withdraw
the stylet approximately 3 cm, rotate the
lead and/or stylet and gently advance the
stylet. If resistance is still encountered,
repeat the above procedure until the stylet
can be fully inserted.
Percutaneous Lead Placement for SCS
WARNING: Do not exchange the lead
stylet while the electrode array of the lead
is in the bevel of the insertion needle. If
the electrode array is in the bevel area,
remove the lead from the insertion needle
before exchanging the stylet. Inserting the
lead stylet in the lead while the electrode
array is in the bevel of the insertion
needle increases the risk of lead and
tissue damage.
WARNING: If the lead stylet is removed
and reinserted, do not use excessive
force when inserting the stylet into the
lead. The use of instruments, such
as forceps, to grasp the stylet during
insertion is not recommended as this
could result in applying excessive force
and could increase the risk of lead and
tissue damage.
CAUTION: Proceed with care, as the
proximal lead tail is susceptible to
contamination and infection.
6. Carefully withdraw the insertion needle to
expose the contacts by slowly pulling the
needle towards the proximal end of the
lead while keeping the lead in the desired
location.
WARNING: Only advance the needle with
the needle stylet in place. Failure to do so
may result in tissue coring.
