Abstract
The invention relates generally to the fields of biology and health sciences. More particularly, the invention relates to compositions and methods for modulating cellular physiology and pathological processing using a combination of compounds that can be found in amniotic membrane tissue and umbilical cord tissue preparations.
Claims (24)
1 . An apparatus for treating diseases or disorders of an eye, by insertion of the apparatus onto a surface of the eye of a patient in need thereof, wherein the apparatus comprises:
one or more circular flexible tubular structures comprising a groove at its perimeter, wherein the apparatus further comprises at least one sheet attached to the groove and stretched across the one or more circular flexible tubular structures, thereby treating diseases or disorders of the eye.
2 . The apparatus according to claim 1 , wherein the one or more circular flexible tubular structures have a length of about 0.5 cm to about 15 cm.
3 . The apparatus according to claim 1 , wherein the one or more circular flexible tubular structures have a cross-sectional diameter of about 0.01 cm to about 1.0 cm.
4 . The apparatus according to claim 1 , wherein the one or more circular flexible tubular structures contains at least one porous inlet and at least one porous outlet.
5 . The apparatus according to claim 4 , wherein the at least one porous inlet and the at least one porous outlet taken together form an osmotic pump when in contact with tears in the eye of the patient.
6 . The apparatus according to claim 4 , wherein the at least one porous inlet and the at least one porous outlet further comprise one or more flexible fastening cuffs.
7 . The apparatus according to claim 6 , wherein an inner surface of the one or more flexible fastening cuffs are frictionally engaging an outer surface of the one or more circular flexible tubular structures.
8 . The apparatus according to claim 1 , wherein the apparatus is configured to deliver one or more therapeutic agents to the patient.
9 . The apparatus according to claim 8 , wherein the one or more therapeutic agents may be frictionally engaged onto a surface of the one or more circular flexible tubular structures, into the one or more circular flexible tubular structures or a combination thereof.
10 . The apparatus according to claim 8 , wherein the one or more therapeutic agents is delivered by diffusion through a net movement of solute from an area of high concentration to an area of low concentration.
11 . The apparatus according to claim 8 , wherein the one or more therapeutic agents is delivered through compression of the apparatus via blinking.
12 . The apparatus according to claim 8 , wherein the one or more therapeutic agents may be one or more sheets covering from about 25% to about 100% of the opening defined by an outer circumference of the one or more circular flexible tubular structures.
13 . The apparatus according to claim 1 , wherein the one or more circular flexible tubular structures are configured to dissolve when in contact with tears in the eye of the patient.
14 . The apparatus according to claim 1 , further comprising umbilical cord tissue, amniotic membrane tissue, placental tissue, chorion tissue, or any combination thereof, wherein the umbilical cord tissue, amniotic membrane tissue, placental tissue, chorion tissue, or any combination thereof may be present in any form from the group consisting of: lyophilized, fresh, sheet, morselized, powder matrix, extract, purified extract, previously frozen, suspension, and on a physiologically acceptable support.
15 . The apparatus according to claim 1 , wherein the apparatus is configured to induce blinking and optionally cover the surface of the eye with a therapeutic agent.
16 . A method to promote an increase in tissue sensation, induce a patient to blink and tear more frequently to prevent dry eye, increase tear breakup time in a patient suffering from dry eye disease, increase tear osmolarity in a patient suffering from dry eye disease, decrease corneal straining in a patient suffering from dry eye disease, increase the score on Schirmer's test in a patient suffering from dry eye disease, promote nerve growth, nerve regeneration, or both when in a contacted tissue, reduce an inflammatory response in a contacted tissue, or a combination thereof, the method comprising inserting the apparatus of claim 1 onto the surface of the eye of the patient.
17 . The method according to claim 16 , wherein the increase in nerve growth is between about 10% and about 100%.
18 . The method according to claim 16 , wherein the increase in nerve regeneration is between about 10% and about 100%.
19 . A method for treating a disease or disorder of an eye of a patient in need thereof, comprising inserting the apparatus of claim 1 onto the surface of the eye of the patient.
20 . The method of claim 19 , wherein the disease or disorder is dry eye disease.
21 . The apparatus of claim 1 , wherein the one or more circular flexible tubular structures comprise a material selected from the group consisting of:
ethylene vinyl acetate (EVA); polydimethylsiloxane (PDMS); polymethylmetacrylate (PMMA); polyethylene teraphthalate (PET); polycarbonate (PC); hydrogels; polyvinyl chloride (PVC); rubber; latex; polyethylene (PE); silicone; polytetrafluoroethylene (PTFE); polyurethane (PU); umbilical cord tissue; amniotic membrane tissue; placental tissue; chorion tissue, and any combination thereof.
22 . The apparatus of claim 1 , wherein the at least one sheet comprises umbilical cord tissue; amniotic membrane tissue; placental tissue; chorion tissue, or any combination thereof.
