Indications for Use

The Cook® Cervical Ripening Balloon is indicated for mechanical dilation of the cervical canal prior to labor induction at term when the cervix is unfavorable for induction.

Device Story

Double-balloon catheter for mechanical cervical ripening; used prior to labor induction at term. Device inserted through vagina and cervical canal into uterus; distal balloon positioned against internal cervical os, proximal balloon against external cervical os. Both balloons inflated with up to 80 mL saline to provide gradual mechanical dilation. Optional malleable stainless steel stylet available to aid catheter placement; removed after positioning. Used in clinical setting by healthcare providers. Benefits include mechanical ripening of unfavorable cervix to facilitate labor induction. Device is sterile, single-use, and indwelling for up to 12 hours.

Clinical Evidence

Bench testing only. Verification testing included balloon deflation reliability, burst testing, volume maintenance, integrity, pullout response, catheter tensile strength, biocompatibility (ISO 10993-1), and simulated use testing.

Technological Characteristics

18 Fr., 40 cm silicone catheter; two silicone balloons (80 mL capacity each); separate inflation lumens with check valves. Optional 46 cm malleable stainless steel stylet with adjustable handle. Sterile, single-use. No electronic components or software.

Indications for Use

Indicated for mechanical dilation of the cervical canal in term patients with an unfavorable cervix prior to labor induction.

Regulatory Classification

Identification

A hygroscopic Laminaria cervical dilator is a device designed to dilate (stretch open) the cervical os by cervical insertion of a conical and expansible material made from the root of a seaweed (Laminaria digitata or Laminaria japonica). The device is used to induce abortion.

#### 4. Comparison to Predicates:

The intended use and technological characteristics of the Cook® Cervical Ripening Balloon are substantially equivalent to the intended use and technological characteristics of the Atad Pre-Induction Cervical Dilator.

#### Device Description ડ.

The Cook® Cervical Ripening Balloon is a double-balloon catheter designed to mechanically ripen the cervix prior to labor induction at term when the cervix is unfavorable for induction. The tip of the Cook® Cervical Ripening Balloon is placed through the vagina and the cervical canal into the uterus. The distal balloon is positioned against the internal cervical os and inflated with up to 80 mL of saline; the proximal balloon is positioned against the external cervical os and also inflated with up to 80 mL of saline. The Cook Cervical Ripening Balloon provides gradual mechanical cervical dilation by simultaneously providing pressure on the internal and external cervical os.

In addition to the standard version, the Cook® Cervical Ripening Balloon is also available with a removable stylet to add rigidity to the catheter and aid in placement of the balloon through the cervix. The stylet runs the length of the catheter shaft of the Cook® Cervical Ripening Balloon in a separate lumen that is closed at the distal tip. The user removes the stylet from the device once the distal uterine balloon is above the level of the internal cervical os.

#### 6. Intended Use

The Cook® Cervical Ripening Balloon is indicated for mechanical dilation of the cervical canal prior to labor induction at term when the cervix is unfavorable for induction.

#### 7. Technological Characteristics

The Cooke Cervical Ripening Balloon consists of an 18 Fr., 40 cm silicone catheter with a silicone tip and two silicone balloons, each inflatable up to 80 mL. Each balloon is inflated via a separate inflation lumen through a check valve at the proximal end of the

{2}------------------------------------------------

device. The check valves are marked with a "U" for the distal, uterine balloon and a "V" for the proximal, vaginal balloon.

For the Cook® Ccrvical Ripening Balloon with Stylet, a 46 cm malleable stainless steel stylet with an adjustable handle is included. The stylet is placed through a separate third lumen that is closed at the distal tip and marked at the proximal end with an "S." The stylet handle allows the user to adjust the stylet so that the distal tip is advanced to the distal (closed) end of the lumen.

The Cook® Cervical Ripening Balloon may be left indwelling for up to 12 hours. The Cook Cervical Ripening Balloon is supplied sterile and is intended for one-time use.

To demonstrate reliable design and performance of the Cook® Cervical Ripening Balloon the following verification testing and information is presented:

- Balloon Deflation Reliability Testing to demonstrate that the balloons . deflate properly after use.
- . Balloon Burst - Testing to demonstrate that the balloons do not burst at the maximum recommended inflation volume under simulated use conditions.
- Balloon Volume Maintenance Testing to demonstrate that the balloons do . not leak.
- . Balloon Integrity - Testing to demonstrate that the balloons do not rupture under simulated use conditions.
- . Balloon Response to Pullout - Testing to demonstrate that the distal balloon does not pull out from the patient under simulated use conditions,
- . Catheter Tensile - Testing to demonstrate that the catheter shaft can sustain the maximum tensile forces anticipated in use.
- . Biocompatibility - Testing to demonstrate that the device is biocompatible. The testing shows that the acceptance criteria from ISO 10993-1 were met.
- . Simulated Use - Testing to demonstrate that the non-clinical users can properly follow the use instructions in a simulated environment.

In conclusion, the results of these tests provide reasonable assurance that the device is as safe and effective as the predicate and support a determination of substantial equivalence.
