LEAD EVALUATION
13
Use the following instructions during the implant procedure:
1. Following insertion of the hemostatic introducer into the vein and
removal of the dilator, hold your thumb over the proximal exposed open-
ing of the TVI tool and insert the distal end of the TVI tool into the proxi-
mal end of the hemostatic introducer by gently pushing the TVI tool
through the hemostatic valve.
Note:
When retaining a guide wire, the TVI tool must be placed over the
guide wire and not along the side of it.
Continue to hold your thumb over the proximal exposed opening of the
TVI tool to prevent air embolization and/or back bleeding. The TVI tool
is fully inserted when the base of its handle contacts the proximal end
of the introducer.
2. Advance the lead through the TVI tool and into the introducer. Continue
to advance the lead until the shocking coil(s) is past the hemostatic
valve.
3. When the lead is resting inside the introducer, pull the TVI tool out of the
hemostatic valve. The TVI tool may be temporarily left on the body of the
lead to facilitate repositioning. Once the lead is in position, the TVI tool
must be peeled away.
Vein Pick
The vein pick is a sterile, disposable, nontoxic, nonpyrogenic, plastic
device designed to assist the physician during entry of the lead’s electrode
tip into the vein.
To use the vein pick during a cutdown
procedure, isolate and open the selected
vein using an appropriate scalpel or
scissors. Introduce the point of the vein pick
via this incision into the lumen of the vein
(Figure 6). With the point of the vein pick
facing in the direction of the desired lead
passage, gently raise and tilt the pick. Pass
the lead under the vein pick and into the
vein.
CAUTION:
The vein pick is not intended either for puncturing the vein or
for dissecting tissue during a cutdown procedure. Be sure that the vein
pick does not puncture the silicone rubber insulation of the lead. This
could prevent proper lead function.
