Intended Use
The CrossBay™ Cervical Dilator Catheter System is intended to be used whenever cervical softening and dilation is desired. Some examples are: - Treatment of cervical stenosis - IUD placement and removal - Placement of instruments for intrauterine radiotherapy - Endometrial biopsy - Global endometrial ablation - Uterine tissue removal - Uterine curettage - Diagnostic hysteroscopy - Operative hysteroscopy This device is not intended for use in the induction of labor.
Device Description
The CrossBay Cervical Dilator Catheter System is a sterile, single use device composed of an inflation device, dilator catheter, everting membrane, and dilator balloon which enable softening and dilation of the cervical canal. The CrossBay Cervical Dilator Catheter System contains an Inflation Device and a Dilator Catheter that accesses the cervix using a hydraulic pressure-filled everting Membrane. The Inflation Device provides the hydraulic energy with saline supplied by the user. Once placed at the exocervix, the Dilator Catheter advances through the cervix by everting the Membrane through the endocervix. A Dilator Balloon is attached to the inner tube of the device that is positioned across the cervix when the everting Membrane is fully everted. The Inflation Device is then used to further pressurize the system to split open the everting Membrane to expose the Dilating Balloon. The Inflation Device is used to pressurize the Dilator Balloon to the prescribed level. Once dilated, the Dilator Catheter is removed from the cervix and the subsequent uterine cavity procedure can commence. The CrossBay Cervical Dilator Catheter with Dilator Balloon is provided in three sizes of 5mm, 7mm, and 9mm. The three sizes are identical except for the diameter of the Dilator Balloon when pressurized.

The device description and performance studies focus on mechanical and hydraulic principles, with no mention of AI or ML algorithms for analysis, decision-making, or control.

No.
The device is used to assist with dilation of the cervix to facilitate other medical procedures such as IUD placement, endometrial biopsy, or hysteroscopy, rather than directly treating a disease or condition itself.

Yes
The "Intended Use / Indications for Use" section lists "Diagnostic hysteroscopy" as one of the procedures for which cervical softening and dilation is desired, indicating that the device can be used in conjunction with a diagnostic procedure.

No

The device description clearly outlines physical components such as an inflation device, dilator catheter, everting membrane, and dilator balloon, indicating it is a hardware-based medical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a device used for physical manipulation of the cervix (softening and dilation) to facilitate various procedures. This is a therapeutic or procedural use, not a diagnostic one.
  • Device Description: The description details a mechanical system involving inflation, membranes, and balloons to physically dilate the cervix. It does not involve the analysis of biological samples or substances to provide diagnostic information.
  • Lack of Diagnostic Elements: There is no mention of analyzing blood, tissue, urine, or any other biological sample. The device's function is purely mechanical.
  • Anatomical Site: The device acts directly on the cervix, a physical structure, rather than analyzing a sample derived from the body.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

----------------------------------------------------------------------------------------------------------------------------------

The subject and predicate device have similar indications for use statements and have the same intended use – for softening and dilation of the cervix. The subject and predicate device list similar procedures for which the device can be used, with some differences in the examples provided for both the subject and predicate device. These procedures are performed following cervical softening and dilation. The listing of different procedures does not raise different questions of safety and effectiveness and does not change the intended use of the subject device.

Comparison of technological characteristics

The following technological similarities exist between the subject and predicate device:

  • Both the subject and predicate device use a delivery catheter with a balloon for dilation of the . cervix.
  • Both the subject and predicate device employ saline as the pressurization media for the balloons.
  • The subject and predicate device have similar working lengths and insertion depths

The following technological differences exist between the subject and predicate device:

  • The subject device utilizes an everting Membrane that advances with the Inner Catheter as the physician manually pushes the Inner Catheter into the Delivery Catheter to place the device across the cervix. Once positioned across the cervix, pressurized saline is used to split the everting Membrane to allow the Dilator Balloon to radially expand the cervix. The same manual advancement action is accomplished in the predicate device using a catheter to traverse the cervix. However, with the predicate device, once across the is pressurized within a separate distal balloon to position the device in the cervix. Within a second port, saline is injected into the dilation balloons to radially expand the cervix.
  • . The subject device has three (3) sizes of Dilator Balloons (5mm, 7mm, and 9mm) and the predicate device is labeled for a nominal diameter of 10mm.
  • The subject device includes a 10 cc Inflation Device and the predicate device includes a 2.5 cc . syringe within the package used to place saline within the catheter. For the predicate device, the 2.5 cc syringe is filled by the user three (3) times separately to pressurize the dilating balloons, whereas the Inflation Device of the subject device is anticipated to be filled once.
  • The subject device is not deflated after dilation during removal from the cervix. The predicate device is deflated prior to removal from the cervix.
  • . The subject and predicate device use different materials in the construction of the catheter and balloon.

Different types of safety and effectiveness questions are not raised by the differences in technological characteristics.
