ABSTRACT:
The invention provides methods for implantation of an embryo into a mammal comprising placing the embryo in a catheter, admitting the catheter through the mammal's cervical os into the endometrial cavity, directing a distal tip of the catheter into the mammal's uterine tissue, and depositing the embryo into the uterine tissue beneath the surface of or within the endometrial lining. Flushing the catheter with a physiologic solution assists in deposition of the embryo. Fiberoptic guidance can facilitate direction of the catheter tip and deposition of the embryo.
