Integra LifeSciences Collagen Wound Dressing, HeliTape, HeliCote, HeliPlug - Manual (Page 2)

Description
The Absorbable Collagen Wound Dressings for Dental Surgery (HeliTape®,
HeliCote®, HeliPlug®) are soft, white, pliable, nonfriable sponges. Because
of the coherent sponge structure, application of the dressings to the wound
is easily controlled. The dressings retain their structural integrity even when
wet. Unwanted dispersal from the site is not encountered.
The Absorbable Collagen Wound Dressings for Dental Surgery are very
porous. Greater than 90% of the dressing consists of open pores, which can
fill with fluid. The dressings are highly absorbent, holding many times their
own weight of saline solution.
The basic material from which the Absorbable Collagen Wound Dressings
for Dental Surgery are fabricated is collagen obtained from bovine deep
flexor (Achilles) tendon. The tendon is one of the purest sources of collagen
that can be readily obtained and processed in commercial quantities.
Because of the high initial purity and further processing achieved during
manufacture, the sponges are safe and effective wound dressings that
exhibit very consistent behavior.
The Absorbable Collagen Wound Dressings for Dental Surgery are nontoxic
and nonpyrogenic. Each dressing is packaged individually. The sterility of
the dressing is guaranteed unless the package is opened or damaged.
The Absorbable Collagen Wound Dressings for Dental Surgery have been
shown to have good adherence to moist wounds. The highly porous
sponge structure absorbs blood and wound exudate. An inherent property
of native collagen is the ability to promote hemostasis. In contact with
blood, collagen is known to cause aggregation of platelets, which bind in
large numbers to the collagen fibrils. The aggregated platelets degranulate,
releasing coagulation factors that enable, together with plasma factors, the
formation of Fibrin.
