2. Once the solid-tipped lead is exteriorized at the jugular incision via passing it through a
cannula (as
described above in device placement description), it’s time to prepare the
vessel for cannulation. Pass 3 pieces of non-absorbable suture around the vessel. The
cranial-most suture will be used to permanently ligate the vessel. Loose knots can be
placed in the other two sutures and the tails left long (see Figure 35).

3. Tension should then be placed on the caudal suture to temporarily occlude blood flow
and on the cranial ligation suture to hold the vessel in place during lead placement. Then
pierce the vessel cranial to the middle tie using the bent needle technique (described
above). You can then choose to use a vein pick to dilate the opening slightly and gently lift
upwards.
5. The solid tipped lead can then be inserted into the vein in a direction toward the heart.
Stop passing once the lead is near the caudal occlusion suture. At this point, the middle tie
can be gently tightened around the lead to secure it in the vessel and then continue
passing the lead into the vein (see Figure 36).
