Intended Use

The CRE™ Balloon Dilatation Catheter is indicated for use in adult and adolescent populations to endoscopically dilate strictures of the esophagus.

Device Story

CRE Balloon Dilatation Catheter is a medical device used by clinicians to endoscopically dilate esophageal strictures. The device consists of a hub, catheter shaft, and a balloon capable of achieving three distinct, progressively larger diameters. It is operated by a physician during endoscopic procedures. By inflating the balloon within the stricture, the device mechanically expands the narrowed esophageal passage, potentially improving patient swallowing and esophageal function. The device is intended for use in clinical settings.

Clinical Evidence

Bench testing only. Laboratory testing was performed to verify safety and performance characteristics. Biocompatibility assessment of patient- and fluid-contact materials yielded satisfactory results.

Technological Characteristics

Components include hub, catheter shaft, and balloon. Capable of three distinct, progressively larger diameter sizes. Biocompatible materials used. No electronic, software, or energy-based components.

Indications for Use

Indicated for adult and adolescent populations requiring endoscopic dilation of esophageal strictures.

Regulatory Classification

Identification

An esophageal dilator is a device that consists of a cylindrical instrument that may be hollow and weighted with mercury or a metal olive-shaped weight that slides on a guide, such as a string or wire and is used to dilate a stricture of the esophagus. This generic type of device includes esophageal or gastrointestinal bougies and the esophageal dilator (metal olive).

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.

Dear Ms. Quaglia:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic OS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register.
