Recovery and processing of human embryos formed in vivo
A process for recovering one or more blastocysts from a uterus of a human includes a step of placing a device transvaginally into a cervical canal of the patient; a step of delivering fluid through the device to the uterus and applying a vacuum to a uterus of the patient to aspirate fluid and entrained one or more blastocysts from the uterus; and a step of performing a biopsy procedure on the one or more recovered blastocysts to remove one or more of trophectoderm cells or inner cell mass from the recovered blastocysts. The process may further include a step of storing one or more of the biopsied trophectoderm cells or inner cell mass following the biopsy procedure and a step of performing at least one molecular diagnostic assay test on the one or more of the biopsied trophectoderm cells or inner cell mass.

12. The method of claim 1 , further comprising performing therapeutic embryonic intervention using selective replacement or gene therapy with specific corrective genetic constructs, specific non-genetic constructs, or stem cell/embryonic cell transplants following the at least one molecular diagnostic assay test.
13. The method of claim 12 , further comprising inserting the therapeutically treated one or more blastocysts into the woman's uterus following said embryonic intervention.
14. The method of claim 1 , wherein the performing the at least one molecular diagnostic assay test on the one or more of the biopsied trophectoderm cells or inner cell mass recovered from the one or more recovered blastocysts further comprises providing one or more reagents comprising nucleotide sequences capable of hybridizing with known chromosomal abnormalities.
15. The method of claim 14 , further comprising providing a microarray or a gene chip which is configured to hybridize with at least one of said chromosomal abnormalities, single gene mutations, corresponding normal sequences or sequences neighboring the chromosomal abnormalities.
16. The method of claim 1 , wherein the performing the biopsy procedure on the one or more recovered blastocysts to remove the one or more of the trophectoderm cells or inner cell mass from the one or more recovered blastocysts comprises using a micropipette to remove the cells.
17. The method of claim 16 further comprising providing a control kit to ensure there is no contamination in the one or more of the biopsied trophectoderm cells or inner cell mass recovered from the one or more recovered blastocysts.
18. The method of claim 1 , wherein the performing the biopsy procedure on the one or more recovered blastocysts to remove the one or more of the trophectoderm cells or inner cell mass recovered from the one or more recovered blastocysts comprises using a laser beam to remove the cells.
19. A method, comprising:
placing a device trans-vaginally into a cervical canal of a human; delivering fluid through the device to a uterus of the human and aspirating fluid and entrained one or more blastocysts from the uterus;
performing a biopsy procedure on the one or more recovered blastocysts to remove one or more of a biopsied trophectoderm cells or an inner cell mass from the one or more recovered blastocysts;
