Optimised for invagination
Vastrip™ Endex is a new product for the stripping of superficial varicose veins by invagination. It was
­perfected by a vascular surgeon, determined to create a product superior to the ones currently on the
­market, one that meets all the demands of modern surgery.
Vastrip Endex is a vein stripper optimised for
­invagination. The support guide has a core of stain­
less steel and a s­ mooth surface that slides easily into
the vein and gives stability through catheterisation.
­The tips are minimally sized to allow easier insertion
in minor veins and to give the best cosmetic result.
­The polyester guide thread is flexible and wound
on a handy reel so that the surgeon can control the
­thread with a minimal risk of contamination.
The design of Vastrip Endex enables either retro­
grade or anterograde insertion from distal or proximal
access. If invagination is interrupted due to rupture ­
of the vein then the procedure can be repeated in the
opposite direction. Vastrip Endex is supplied with
three sizes of olive so that if the vein proves unsuit­
able for invagination techniques, stripping can be
com­pleted using traditional methods.

tripping by invagination from
above downwards
The support guide (A) of Vastrip
Endex is introduced into the cut
vein from the groin downwards
(or, if preferred, from the ankle
upwards) ­and passed through
the entire length of the vein. The
support guide can now be cut
off, ­leaving only the protruding
flexible thread.
Invagination
Stripping of varicose veins by invagination is
­considered less traumatic than traditional external
or internal stripping (1). It is also a general opinion
that damage to the ­saphenous nerve is seen less
­frequently when ­the vein is stripped by invagination
compared to traditional stripping.
Vastrip Endex allows the surgeon flexibility.
Stripping by invagination is easily accomplished ­for
most veins and Vastrip Endex gives the surgeon the
choice of either retrograde or anterograde insertion.
If the vein fractures when invagination is ­attempted
then stripping can be repeated in the opposite
direction, or by the more traditional method using
an olive.
The flexible thread is drawn
through the lumen, by pulling
the thread at the ankle incision,
until the mid-point sleeve (B)
reaches the vein aperture. A
­
ligature is placed on the vein,
below the mid-point sleeve. ­

The proximal vein segment (C)
is cut off.

Pulling the thread downwards
starts invagination of the vein
(turning it outside in). Retaining
the adventitia approximately
2 cm underneath the ligature
with two forceps facil­itates
invagination. Stripping of the
vein is then performed from
above downwards.
Catheterisation
Catheterisation of the
vein can be performed ­
in both anterograde and
retrograde directions.
Stripping is then best
accomplished from above
downwards.

3. Traditional stripping
In case of a rupture, the pro­
cedure described under #1 can
be repeated but in the opposite
direction. First, the loose vein
segment is completely removed.
If the vein cannot be completely
removed by the described pro­
cedures, stripping can be com­
pleted in a traditional way by
the use of an olive. Select the
appropriate size of olive (6, 9
or 12 mm) and ensure that it is
securely mounted on the t­hread:
Place the mid point sleeve and
the knot facing the flat end of
the olive inside the olive’s wide
slit. The knot facing the olive’s
conical end should be placed
outside the olive.
A ligature is placed on the
vein, above the mid-point
­sleeve. Pulling the thread
up­wards starts invagination
of the remaining vein segment.
Re­taining the adventitia
approxim­ately 2 cm above
the ligature with two forceps
facilitates invagination.
Stripping of the vein is then
per­formed in the opposite
­direction.
Press the mid point sleeve into
the slit, a click confirms that it
is in position.
The olive should be able to
rotate freely. If necessary,
­centre the thread into the slitends with a pull.
When the olive is correctly
mounted, the knot facing the
olive’s flat end and the mid
point sleeve are entirely inside
the slit and the knot facing the
conical end is outside the olive.
Holder with integrated thread reel
Vastrip Endex is supplied on a sterile holder with an
integral thread reel. The polyester t­hread is wound
on the reel a
­ llowing the
surgeon ­to easily control
un­winding of the thread
with minimal risk of
contamination. ­The
length of the t­hread is
2.5 m. The support
guide is 1 m long with
a diameter of 2 mm.
Material
Stainless steel (Support guide), PVC (Support guide,
Mid-point sleeve), Polypropylene (Olives, Holder),
Polyester (Thread).
Sterilisation
The products are sterilised using ethylene oxide.
Single use

Mid-point sleeve
One of the unique
­features of Vastrip
Endex is the mid-point
sleeve, which is fixed
in the middle of the
flexible thread. In the event of the vein t­earing
during the invagination, this mid-point sleeve
allows the invagination to be completed b
­y
­reversing the direction of strip.
