The summary describes a standard tocodynamometer for measuring uterine activity and makes no mention of AI or ML.
No
The device is described as a tocodynamometer intended for the evaluation of external uterine activity, which is a diagnostic or monitoring function, not a therapeutic one.
Yes
The device is described as a "tocodynamometer" intended for "evaluation of external uterine activity" during antepartum and intrapartum periods, which is a diagnostic purpose.
No
The device description explicitly states it is a "tocodynamometer," which is a physical sensor used to measure uterine contractions. It also mentions being held on the abdomen with a belt and being submersible, indicating a hardware component.
Based on the provided information, the FeatherLite Aqua™ Toco dynamometer is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information about a person's health.
- FeatherLite Aqua™ Toco Function: The FeatherLite Aqua™ Toco dynamometer is an external device placed on the abdomen to measure uterine activity. It does not analyze any bodily fluids or tissues.
- Intended Use: The intended use clearly states it's for "evaluation of external uterine activity." This is a physical measurement, not an in vitro analysis.
Therefore, the FeatherLite Aqua™ Toco dynamometer falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The FeatherLite Aqua™Toco dynamometer is intended for use in conjunction with telemetry systems for standard fetal monitors for the evaluation of external uterine activity during antepartum and intrapartum periods. Is should only be used in a clinical setting. It may be fully submerged in water for water birthing or monitoring in a whirlpool. Caution: FeatherLite Aqua™Toco is not intended for home monitoring of pre-term labor.

§ 884.2720 External uterine contraction monitor and accessories.
(a)
Identification. An external uterine contraction monitor (i.e., the tokodynamometer) is a device used to monitor the progress of labor. It measures the duration, frequency, and relative pressure of uterine contractions with a transducer strapped to the maternal abdomen. This generic type of device may include an external pressure transducer, support straps, and other patient and equipment supports.(b)
Classification. Class II (performance standards).

Summary of Similarities and Differences:
Similarities:
Ventrex FeatherLite™ Toco under 510(k) K013477 (Predicate Device) and FeatherLite Aqua™ Toco (New Device):
- Both are used in conjunction with fetal monitors for evaluation of external . uterine activity.
- Same performance characteristics. .
- Both use a flexible nipple and silicone gel to transmit the changes in uterine . wall muscle tone to the strain gauge pressure sensor housed inside.
- The sensor for both FeatherLite™ and FeatherLite Aqua™ are the same. . (resistive type)
- . The housing materials are the same . (molded from rigid thermoplastics)
- The same attachment methods.
- ◆ Both devices cannot be serviced.
- Both use an adaptor to connect the universal connector of the cable to the . specific fetal monitor.
Differences:
- Atmospheric pressure referencing on the predicate device is achieved through . a vent hole on top of the housing while the venting on new device is achieved through a lumen in the cable.
- The FeatherLite Aqua™ Toco may be used in a water environment. .
- The cover is sealed to the housing using a water proof sealant for the new . device to prevent water from entering.
- The adapter includes a digital filter to minimize unwanted noise without . interfering with performance.
- The adapter has a switch to allow the user to increase the toco gain for more . effective monitoring of obese patients.
- The FeatherLite Aqua™ is intended for single use only. .
- The FeatherLite Aqua™ shall ONLY be used with telemetry units. .
Similarities: GE/Corometrics 2264 Tocodynamometer under K982651.
- Same principle of sensing the change in muscle tone of the uterus as it . contracts by firmly holding a nipple-like appendage against the abdominal wall utilizing an elastic belt as the holding means.
- . Both devices can be used in either water or non-water environments.
- Both devices require a telemetry unit when used as a submersible device. .
2
Differences:
- Monitor connector is hard wired onto the cable of the predicate device. .
- Predicate device has an electronic filtering circuitry in the toco. New device has . in the adaptor.
CONCLUSION:
- The proposed FeatherLite Aqua™ (New Device) is comparable to its predicate . devices in safety and effectiveness.
