## Indications for Use

The Kitazato OPU Needles consisting of: - Kitazato OPU Needle with Connection Tube, model number Type 2 - Kitazato OPU Reduced Needle, model number Type 3 are intended to obtain oocytes from ovarian follicles.

## Device Story

Kitazato OPU Needles are sterile, single-use devices designed for transvaginal puncture of ovarian follicles to aspirate oocytes. The device consists of a stainless steel aspiration needle, a connection tube, and a silicone stopper connector. Available in two configurations: Type 2 (standard aspiration needle) and Type 3 (reduced needle with a narrow tip). The clinician performs the procedure under ultrasound guidance to locate follicles, punctures the vaginal wall, and aspirates the follicular fluid containing oocytes. The output is the collected oocyte sample, which is then processed in a laboratory setting for assisted reproduction. The device facilitates oocyte retrieval, a critical step in IVF and other fertility treatments.

## Clinical Evidence

Bench testing only. Testing included mechanical tensile strength (withstanding 22N for O.D. <0.55mm), bending elasticity (returning to position after 8° bend), folding strength (no fracture at 90°), dimensional verification, endotoxin levels (≤20 EU/device), and sterility. Mouse embryo assay demonstrated ≥80% expansion to blastocyst stage within 96 hours, confirming biocompatibility for reproductive use.

## Technological Characteristics

Needle assembly consisting of stainless steel needle, connection tube, and silicone stopper. Available in gauges 16G to 24G (Type 2) and 18G with 21G-23G narrow tips (Type 3). Sterilized device. Biocompatibility verified per international standards.

## Regulatory Identification

Assisted reproduction needles are devices used in in vitro fertilization (IVF), gamete intrafallopian transfer (GIFT), or other assisted reproduction procedures to obtain gametes from the body or introduce gametes, zygote(s), preembryo(s) and/or embryo(s) into the body. This generic type of device may include a single or double lumen needle and component parts, including needle guides, such as those used with ultrasound.

## Special Controls

*Classification.* Class II (special controls) (mouse embryo assay information, endotoxin testing, sterilization validation, design specifications, labeling requirements, biocompatibility testing, and clinical testing).

### 8. Substantial Equivalence Discussion

The indication for use and technology of the OPU Needle are substantially equivalent to the identified predicate devices.

#### 9. Non-Clinical Testing

The needle mechanical tensile testing and mouse embryo testing results supports that all the specifications have met the acceptance criteria for the device. The Kitazato OPU Needles passed all testing and supports the claims of substantial equivalence.

- . Mechanical Tensile Testing: Tensile strength to withstand 22N for needle tube O.D. <0.55 mm
- . Bending Elasticity Testing: Return normal position after bending 8° from straight for needle tube O.D. ≤1.0 mm
- Folding Strength Testing: No fracture of needle tube is detected when needle tube . of O.D. ≤1.0 mm and length ≥12mm is folded to 90°
- Dimensional Testing: Passes outer diameter and length according to specifications .
- Endotoxin Testing: Endotoxin values conform to the value ≤20 EU/device �
- Sterility Testing: No microbial growth from sterility testing .
- t Mouse Embryo Assay: ≥80% expanded to blastocyst stage within 96 hours

The Kitazato OPU Needles were tested and complies with the applicable voluntary standards for biocompatibility and sterilization. The device passed all the testing in accordance with national and international standards.

#### 10. Conclusion

:

The Kitazato OPU Needles are substantially equivalent to its proposed predicate devices.

Dear Mr. Vincins:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
