OPTIONS: MEDPORŽ Biomaterial and Surgical Implants
 MEDPORŽ Biomaterial
MEDPOR Surgical Implants are manufactured from linear
high-density polyethylene. Polyethylene has a long history of use in
surgical implants. MEDPOR Biomaterial allows for tissue ingrowth
because of its interconnecting open pore structure. The porosity of
MEDPOR Biomaterial is maintained large with average pore sizes
greater than 100 micro-meters and a pore volume in the 50 percent
range (based on Mercury Intrusion Porosimetry measurements). The
firm nature of the material allows carving with a sharp instrument
without collapsing the pore structure.
Animal data has demonstrated that MEDPOR surgical implant
material permits tissue ingrowth. Histologic analyses of biopsies
from human implants have also demonstrated tissue ingrowth. The
clinical significance of tissue ingrowth varies with the application
and implant site. The long term clinical effect of this
characteristic has not been established.
In Vitro and In Vivo biocompatibility studies have shown MEDPOR
surgical implants to be void of any observable systemic or cytotoxic
effects.

Surgical implant shapes are manufactured in a wide variety
of shapes and sizes for use in craniofacial reconstruction and
augmentations. MEDPOR block, sheet and pre-formed shapes are
intended for augmentation or restoration of contour in the
craniofacial skeleton. |
 |
Implants are provided STERILE, packaged individually in double
peel pouches.
MEDPOR provides many versatile options for craniofacial
reconstruction and aesthetic augmentation. The material is easy to
handle and manipulate. It is used in several applications which
include cranial, orbital, nasal, malar, mental and auricular
surgical procedures. Standard shapes, sheets and blocks are may be
modified by the surgeon to address a patient's specific needs. The
following illustrations depict the ease in which MEDPOR Biomaterial
may be handled.

surgical techniques. Surgeons should utilize proper surgical
techniques for which they are trained and their clinical
experience to determine appropriate surgical procedures.
Successful implantations are technique sensitive and depend on
a number of clinical factors. Sound surgical judgment should
be used in the selection and use of all products. Complete
product labeling is included in the package insert provided
with each product. The surgeon should adequately review this
