is is a process patent describing the formation of the microporous membrane. A proces
s
patent is granted on a new, useful, and unobvious technical process.
e process describes the formation of microporolus flat sheets, or hollow fibers, by
casting a desired thickness of solvent-based “Mitrathane

i s is a divisional application of 4,704,130 above.
is patent covers the shape and size of porous structures and dimensions obtainable
with the casting/precipitation/extraction drying method.
e sheets covered in the patent have: (1) a void volume of 50–80%, (2) a surface layerpore
size of 0.1 to 28 microns, and (3) a contiguous layer of finger-like voids of 100 to 500
microns, extending normal to the surface skin layer.

is is important, since wound dressings need to absorb large quantities of exudate and
retention of physical properties is necessary to prevent rupture during removal ofawound
dressing.

is is a product, or design, patent. Product patents are obtained on new, useful,
andunobvious product constructions.
e patent describes t wo s tructures: (1) a bilaminate structure composed o f an a bsorbent
porous sheet and a porous adhesive, and (2) a trilaminate structure composedof
a
liquid-impermeable film, an absorbent porous sheet, and a porous adhesive.
Further, the patent describes an adhesive layer with an aperture opening of one to
fifteenpercent, where fragments of the adhesive are retained within the pores of th
e
macroporous sheet without blocking fluid channels.

e application describes a process for manufacturing an adhesive-faced laminate,
suitable as wound dressing, burn dressing, surgical drape, etc.
e patent discloses the process of making microporous adhesive laminated sheets
bylaminating, compressing and releasing an acrylic adhesive mass against a porou
s
polyurethane membrane.
Hy
drophilic Polyurethane Elastomers.
is is a composition-of-matter patent application. e application describes th
e
synthesis of UV-curable elastomers. ese elastomers are synthesized in the presence
ofa novel polymerizable photoinitiator, which becomes part of the molecular chain.
Because the photoinitiator becomes chemically bound into the elastomer, the finished
polymer has essentially no extractables, an advantageous characteristic for use in drug
delivery systems.

Further, the polymer can be formed in the absence of heat, since it cures upon exposure to
UV radiation for a period of two minutes at room temperature.
Bios
table Polyurethane Products.
A composition-of-matter application concerning polyurethane products possessing
long-term biostability, in combination with a low modulus of elasticity, high ultimate
strength and other desirable mechanical properties. ese properties are crucial in
medical devices such as pacemaker lead insulators, vascular grafts, mammary prostheses
,
and other medical products which are intended to be placed within the body for extended
periods with no substantial degradation of the product.

e Company is in the process of fitting out a 9,000 square foot manufacturing and
labo
ratory facility in Woburn, Massachusetts and is upgrading its manufacturing plant and
labo
ratories in Wheat Ridge, Colorado. e Company expects to have capital needs in the
spec
ific areas outlined below as well as the need for general working capital:

Form, fill and seal packager ............................................................... 60,000
Rewinder/slitter/inspection station ................................................. 50,000

At present, the Company produces Mitraflex

in a 30

at

"
wide casting machine, run at 3.0 ft./min., will effectively double the
Co
mpany’s production capacity, thereby reducing manufacturing costs by more than half.
In addition, a wider membrane will allow wider casting/laminating and reduce conversion
cost
s by half.
A form, fill and seal packager, in conjunction with a rotary die cutter, will quintuple our
pa
ckaging capacity. Packaging is our current production bottleneck.
e rewinder is necessary to inspect rolls of converted Mitraflex
TM
, prior to die cutti
ng.
It w
ill also be used to slit the converted rolls into strips in preparation for rotary die cutting.
