No
The device description and intended use are purely mechanical, and there are no mentions of AI, ML, or related concepts in the provided text.
Yes
The device is used for mechanical dilation of the cervical canal, which is a medical procedure to prepare the cervix for labor induction. This falls under the definition of a therapeutic device as it treats or modifies a physiological process.
No
The device is described as a mechanical dilator for the cervical canal. Its intended use is to dilate the cervix, not to diagnose a condition.
No
The device description clearly states it is a physical catheter with balloons, made of natural latex, indicating it is a hardware device.
Based on the provided information, the Atad Pre-Induction Cervical Dilator is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Atad Dilator Function: The Atad Dilator is a mechanical device used to physically dilate the cervical canal. It acts directly on the body, not on a specimen taken from the body.
- Intended Use: The intended use clearly states "mechanical dilation of the cervical canal prior to labor induction." This is a physical intervention, not a diagnostic test performed on a sample.
Therefore, the Atad Pre-Induction Cervical Dilator falls under the category of a medical device but not specifically an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Atad Dilator is indicated for mechanical dilation of the cervical canal prior to labor induction at term when the cervix is unfavorable for induction.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Atad Dilator has been subjected to all appropriate biocompatibility and performance testing including burst, pressure and flow rate testing. The device was found acceptable in all non-clinical testing phases. The safety and effectiveness of the Atad Dilator for cervical dilation prior to labor induction in women at term has been demonstrated in several clinical trials.

Summary of Technological Characteristics: 6.
The Atad Dilator produces cervical dilation by the internal instillation of water in controlled spaces at the ends of the cervical canal. It is introduced through the lumen and expands the internal balloons. The operation is similar to laminaria which similarly expand internally within the canal through the absorption of water. The technological characteristics differ from those of a laminaria in terms of design, material and performance "mechanics." However, the design, materials and performance "mechanics" are comparable to marketed catheters and cannulas used for other purposes but which have exposure to the same body parts and locations. In particular, the Atad Dilator is comparable to the COOK Balloon Cannula and the COOK Double Balloon Hysterosalpingography Catheter (K890869).
The Atad Dilator, as with the laminaria, is inserted through the cervical canal and pressure is applied on the cervix by water-filled balloons inflated at the extremities of the cervix. This gradually will dilate the cervix in a period of approximately 6-12 hours. The predicate device laminaria is inserted through the cervical canal and is kept in place approximately 6-24 hours. By its hygroscopic capability, the expanded laminaria applies a gradual pressure on the cervix to effect its dilation. The Atad Dilator is inflated with 80 mL of sterile water or saline in each balloon. Following inflation of the two balloons positioned at the extremities of the cervix, pressure is applied on the cervix. The pressure applied by the balloons on the extremities of the cervix will dilate the cervix. Clinical trials support this effect in both the Atad Dilator and its predicate device, the laminaria. Cervical dilation of 3-4 cm occurs with the Atad Dilator.
