The description focuses on the mechanical components and function of the device for sample collection, with no mention of AI or ML capabilities. The performance studies evaluate mechanical properties and clinical outcomes related to sample collection and navigation, not algorithmic performance.
No.
The device is used to collect cell samples for diagnostic purposes (cytological evaluation), not to treat a condition or restore a function.
Yes
Explanation: The device is used to obtain samples from the fallopian tube for cytological evaluation, which is a diagnostic purpose.
No
The device description explicitly details physical components such as a catheter, handle, balloon, shaft, sheath, sheath knob, drive wheel, and extension tube. It also mentions mechanical testing and sterilization, indicating it is a physical medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. The key is that the diagnostic process happens outside the body (in vitro).
- MAKO 7 Function: The MAKO 7 is a device used to collect the sample (cells from the fallopian tube). It is a tool for obtaining the specimen, not for performing the diagnostic test on the specimen itself.
- Cytological Evaluation: The description states the samples are for "cytological evaluation." This evaluation is the diagnostic process, which would be performed in a laboratory using techniques like microscopy. The MAKO 7 facilitates this process by providing the sample, but it doesn't perform the evaluation.
Therefore, the MAKO 7 is a sample collection device, not an In Vitro Diagnostic device.

Device Description
The MAKO 7 is a hysteroscope accessory intended to collect cell samples from the fallopian tube. The device is comprised of a catheter and a handle. The catheter includes a balloon, a shaft (which is made up of a stainless steel tube and a Nylon tube), a sheath (Nylon 12), and a sheath knob (Polycarbonate). The handle includes a drive wheel and an extension tube that is attached to a luer in the handle body. The extension tube attaches to a commercially available inflation device via a commercially available 3-way stopcock. In summary, the physician inserts the MAKO 7 into the working channel of the hysteroscope until the distal tip of the catheter is positioned immediately proximal to the ostium of the fallopian tube. Then, the balloon is advanced into the fallopian tube and cells are collected on its surface. The MAKO 7 is a sterile, single-use device. The device is terminally sterilized using ethylene oxide (EO).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Nonclinical and clinical testing included the following:
Mechanical testing
- Dimensional (sample size of n=15 was used for each test)
- Deployment (sample size of n=15 was used for each test)
- Inflation Pressure (sample size of n=15 for each test)
Ergonomics - Physician feedback on MAKO 7 confirmed handle ergonomics, drive wheel ergonomics, hysteroscopic visibility of balloon deployment, and ability to follow the IFU.
- A sample size of 3 physicians per parameter was used.
Clinical testing
A prospective, single-arm clinical study was conducted to demonstrate the safety and effectiveness of the subject device in navigating the fallopian tube and obtaining cell samples. The MAKO 7 was evaluated in 40 subjects (80 fallopian tubes) who were already scheduled to undergo a laparoscopic tubal ligation.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Study endpoints included 1) ability of the device to navigate the fallopian tube, 2) ability of the device to collect a sample adequate for cytological evaluation, and 3) adverse events. Access was achieved in 71/80 (89%) fallopian tubes. The remaining 9 tubes were determined to have pre-existing tubal occlusion, as determined by methylene blue dye injection (in two of the tubes not initially accessed a second access and navigation was successful after incidental clearing of tubal blockage after methylene blue dye injection).
The study pathologist determined that 70/71 (99 %) of the samples were adequate for cytological evaluation.
There were no device-related adverse events reported.

IV. DEVICE DESCRIPTION
The MAKO 7 is a hysteroscope accessory intended to collect cell samples from the fallopian tube. The device is comprised of a catheter and a handle. The catheter includes a balloon, a shaft (which is made up of a stainless steel tube and a Nylon tube), a sheath (Nylon 12), and a sheath knob (Polycarbonate). The handle includes a drive wheel and an extension tube that is attached to a luer in the handle body. The extension tube attaches to a commercially available inflation device via a commercially available 3-way stopcock.
In summary, the physician inserts the MAKO 7 into the working channel of the hysteroscope until the distal tip of the catheter is positioned immediately proximal to the ostium of the fallopian tube. Then, the balloon is advanced into the fallopian tube and cells are collected on its surface.
The MAKO 7 is a sterile, single-use device. The device is terminally sterilized using ethylene oxide (EO).
The device is intended for use in the hospital/clinic/physician's office.
The duration and type of contact is classified as follows:
- Category: External Communicating Device ●
- Contact: Mucosal membrane
- Duration: A - Less than 24 hours
INTENDED USE/INDICATIONS FOR USE V.
The indications for use for the subject device are as follows:
The MAKO 7 is a hysteroscope accessory, placed through the working channel of a hysteroscope to obtain samples from the fallopian tube for cytological evaluation.
The indications for use differ from that of the predicate, in that the indication for use for the subject device refers to the collection of samples from the fallopian tube instead of the proximal fallopian tube only. This difference does not represent a new intended use, since 1) device use is in the same anatomical structure – the fallopian tube, and 21 the difference in location within the fallopian tube does not alter the general purpose of the device to collect cells for cytological evaluation. As described in FDA's July 2014 guidance regarding evaluating substantial equivalence, the proposed indication is a "tool type" indication, which is not affected by the change in location within the fallopian tube.
5
Also, reference to device use in the fallopian tube does not raise different questions of safety and effectiveness as compared to use within the proximal portion of the fallopian tube.
VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
The mechanism of action and principles of operation of the subject device and the predicate device are identical. Both devices use an identical handle, catheter body, and, most distally, a balloon that collects the sample. For both devices, this distal portion is actuated by a drive wheel on the handle and a hysteroscopic view is required.
There is only one difference in design between the predicate device and the subject device. This difference is that the balloon of the subject device extends 7cm into the fallopian tube while the balloon of the predicate device extends 2.5cm into the fallopian tube.
Since the subject and predicate devices collect cells by the same mechanism and in the same anatomical structure, and because the handle body, catheter body, and cell collection portion are the same, the subject device does not raise different questions of safety or effectiveness. There are also no new risks for collection of cells in the fallopian tube as compared to cell collection in the proximal fallopian tube. Indeed, in a clinical study of the subject device, no adverse events were reported.
VII. PERFORMANCE DATA
Nonclinical and clinical testing included the following:
Mechanical testing
- Dimensional (sample size of n=15 was used for each test) ●
- Deployment (sample size of n=15 was used for each test) ●
- Inflation Pressure (sample size of n=15 for each test)
Ergonomics
- Physician feedback on MAKO 7 confirmed handle ergonomics, drive wheel ● ergonomics, hysteroscopic visibility of balloon deployment, and ability to follow the IFU.
- . A sample size of 3 physicians per parameter was used.
Clinical testing
A prospective, single-arm clinical study was conducted to demonstrate the safety and effectiveness of the subject device in navigating the fallopian tube and obtaining cell samples. The MAKO 7 was evaluated in 40 subjects (80 fallopian tubes) who were already scheduled to undergo a laparoscopic tubal ligation.

Study endpoints included 1) ability of the device to navigate the fallopian tube, 2) ability of the device to collect a sample adequate for cytological evaluation, and 3) adverse events. Access was achieved in 71/80 (89%) fallopian tubes. The remaining 9 tubes were determined to have pre-existing tubal occlusion, as determined by methylene blue dye injection (in two of the tubes not initially accessed a second access and navigation was successful after incidental clearing of tubal blockage after methylene blue dye injection).
The study pathologist determined that 70/71 (99 %) of the samples were adequate for cytological evaluation.
There were no device-related adverse events reported.
VIII. CONCLUSION
The bench and clinical performance data provided in support of the 510(k) confirm that the MAKO 7 subject device is as safe and effective and substantially equivalent to the MAKO 2.5 predicate device.
