Liquid amnion transplant product
A transplant product made from human amniotic fluid has a supernatant from filtered and centrifuged amniotic fluid, the amniotic fluid when recovered aseptically having a clear, translucent to slightly pink or tan color. The supernatant had been taken from the amniotic fluid which had been passed through a 170 to 260 micron blood filter, then centrifuged for 5 minutes or more at 400 g and thereafter the supernatant was separated from a pellet of debris, leaving the biochemical properties intact, wherein the supernatant is cryofrozen in sized cryovials having 0.25 to 2.0 ml of the supernatant at a temperature of −65 degrees or less prior to use and the transplant products method of use. The transplant product contains cellular material, cell fragments, proteins and growth factors maintaining the biochemical properties and is non-immunogenic while having particles up to 170 microns being passable through a 30 gauge syringe for injection.
1. A method for a transplant product made from human amniotic fluid, comprising the steps of:
aseptically recovering a volume of greater than 100 ml of sterile human amniotic fluid from a woman;
visualizing the removed volume has a pink to clear color and contains no vernix;
filtering said amniotic fluid through a blood filter with a pore size of 170 to 260 microns;
placing the filtered amniotic fluid in a plurality of centrifuge tubes; and
wherein the process of filtering the amniotic fluid is performed to ensure the biochemical properties of the tissue remain intact.
2. The method for a transplant product made from human amniotic fluid of claim 1 further comprises the step of transferring the filtered amniotic fluid tissues in the centrifuge tubes into a calibrated centrifuge; centrifuging at a centrifuge cycle of 5 minutes at 400 g, wherein when the cycle is complete, the centrifuged fluid is separated into a supernatant from the amniotic fluid and a pellet containing debris; the supernatant is carefully removed and separated from the pellet and set aside for further processing.
3. The method for a transplant product made from human amniotic fluid of claim 2 further comprises the step of aliquoting the supernatant of liquid amnion into sized cryovials of transplant product sizes in the range of 0.25 ml to 2.0 ml.
4. The method for a transplant product made from human amniotic fluid of claim 3 wherein a smaller volume of the 0.25 mL and 0.5 mL transplant product size is placed into 1.8 mL cryovials and a larger volume 1.0 mL and 2.0 mL transplant product size is placed into the larger 4.5 mL cryovials, the volumes being aliquoted into the appropriate sized cryovials using a calibrated pipette.
5. The method for a transplant product made from human amniotic fluid of claim 4 are randomly selected filled cryovials are used for liquid microbiology cultures that represent the transplant product.
6. The method for a transplant product made from human amniotic fluid of claim 4 wherein the cryovials after being filled with supernatant from the amniotic fluid are packaged, inspected and stored in the absence of a cryopreservative in a −65° C. or colder freezer.
7. The method for a transplant product made from human amniotic fluid of claim 6 wherein the sized volume of frozen supernatant when thawed and resuspended in a diluent for use has a viscosity approximating water and is injectable through a 30 gauge needle.
8. A method of treatment using the transplant product according to claim 7 comprising the steps of:
taking a sterile syringe with at least a 30 gauge needle and filling it with the thawed and resuspended supernatant of amniotic fluid; and
injecting the fluid into the patient to be treated.
9. The method of treatment using the transplant product of claim 8 wherein the patient to be treated has one or more of the following conditions of damaged or injured tissue, or a degenerative tissue condition and the injection of the supernatant from amniotic fluid is a treatment for said condition.
10. The method for a transplant product made from human amniotic fluid of claim 6 wherein the supernatant of amniotic fluid when thawed is non-immunogenic and has preserved the biochemical properties.
