Egg preparation in an intelligent automated in vitro fertilization and intracytoplasmic sperm injection platform

1. A method for automated, artificial-intelligence-based retrieval of a cumulus-oocyte-complex (COC) including an oocyte and cumulus cells, the method comprising:

placing a vessel containing a follicular fluid sample on a motorized stage of a microscope;

scanning the follicular fluid sample, robotically, using an imaging system and an artificial intelligence/machine learning system (AI/ML system) to create an image object, wherein:

the imaging system includes a microscopy system, a camera system, and a lighting system, and

the robotically scanning the follicular fluid sample includes controlling the motorized stage to move in a specified pattern and autonomously managing autofocusing and zooming to create the image object;

identifying the COC within the image object, and a location of the COC, based at least in part on comparing the image object to a predetermined threshold using an AI/ML system, wherein the predetermined threshold is an optical pattern with a probability of corresponding to a COC mass;

instructing a robotic pipettor to move to the location to be adjacent to the COC;

determining an intake volume based on outer physical limits of the COC detected in the image object;

once the robotic pipettor is adjacent to the COC, beginning aspiration, using the robotic pipettor, based at least in part by applying negative pressure to the COC and adjacent fluid to aspirate the intake volume;

removing the robotic pipettor from the vessel;

moving the motorized stage to present a wash dish containing handling medium in proximity to the robotic pipettor;

lowering the robotic pipettor into a wash area of the wash dish for removal of the cumulus cells from the COC; and

applying positive pressure to the robotic pipettor to expel a volume of the COC and adjacent fluid into the handling medium, wherein the expelled volume is controlled at least in part using the AI/ML system, so that an end of the positive pressure corresponds to a time at which the COC mass exits the robotic pipettor.

2. The method of claim 1 wherein the vessel and the wash dish are a single, common container.

3. The method of claim 1 wherein the microscope is an inverted microscope.

4. The method of claim 1 wherein the microscope is a movable microscope.

5. The method of claim 1 wherein the intake volume is determined at least in part by the AI/ML system.

6. The method of claim 1 wherein the COC is a plurality of COCs.

7. The method of claim 1 wherein the robotic pipettor is a plurality of robotic pipettes.

8. The method of claim 1 wherein scanning the follicular fluid sample is automatically performed using at least in part the AI/ML system and the imaging system.

9. The method of claim 1 wherein the aspiration continues until the AI/ML system and the imaging system verify completion.

10. The method of claim 9 wherein verifying the completion is performed using the AI/ML system and the imaging system to confirm that the COC mass is sufficiently isolated from other matter based at least in part on a second image taken during or following aspiration.

11. The method of claim 1 wherein instructing the robotic pipettor to move to the location includes:

instructing the robotic pipettor to enter the follicular fluid sample at a distance from the location; and

after entering the follicular fluid sample, causing the robotic pipettor to approach the COC.

12. The method of claim 11 wherein:

instructing the robotic pipettor to enter the follicular fluid sample includes instructing the robotic pipettor to translate vertically into the follicular fluid sample; and

causing the robotic pipettor to approach the COC includes controlling the motorized stage.
