The summary describes a mechanical balloon dilator and its physical properties and performance testing. There is no mention of AI or ML in the device description, intended use, or performance studies.
Yes
The device is used to dilate the lower esophageal sphincter, which is a treatment for Achalasia. This indicates a therapeutic (treatment) purpose.
No
The device is described as a dilation balloon used to treat Achalasia, not to diagnose it. The performance studies listed are related to the physical properties and safety of the balloon for its intended therapeutic use.
No
The device description clearly outlines physical components such as a balloon, catheter, Y junction, extension lines, wire guide hub, inflation hub, ink markers, and radiopaque bands, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The device is used to physically dilate the lower esophageal sphincter in patients with Achalasia. This is a therapeutic intervention performed directly on the patient's body.
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not involve the analysis of such specimens.
- Device Description: The description details a physical balloon catheter designed for insertion and inflation within the body.
- Anatomical Site: The device acts on the lower esophageal sphincter, an internal anatomical site.
The device is a therapeutic medical device used for a physical procedure, not for analyzing biological samples.

Device Description
The subject dilation balloon consists of an PET balloon attached to a 75 cm that is secured to a white Pebax Y junction with two extension lines leading with a wire guide hub and an inflation hub. The catheter has four black ink markers on the catheter.
The dilation balloon is composed of PET, with a patient contacting length of 8 cm which can be inflated to a single size of 30 mm or 35 mm in diameter. The balloon has a 1.16" long tip made of white Neuthane. Three tantalum radiopaque bands are placed underneath the balloon to assist in fluoroscopic visualization of the balloon.

Dear Theresa de Prat:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You mav, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be avare that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions.

Comparison to Predicate Device
The subject device, the Wilson-Cook Achalasia Balloon, is substantially equivalent to the Rigiflex II Single-Use Achalasia Balloon Dilator (K050232) with respect to intended use, operating mechanism, technological characteristics.
Minor changes exist from the predicate Rigiflex II Single-Use Achalasia Balloon Dilator to the Wilson Cook Achalasia Balloon (subject device).
The subject device has a more specific intended use, different materials of construction, a shorter balloon patient contacting length, dimensional differences in catheter dimeter and length and provided non-sterile. The subject device has a maximum balloon inflation pressure of 3.0 atm while the predicate has a maximum inflation pressure of 1.36 atm. These minor differences do not raise new questions of safety or effectiveness.
Summary of Non-Clinical Testing
The following performance testing was conducted to demonstrate performance of the subject device and confirmed that the subject device performs as intended.
- Balloon Diameter and Length ●
- Balloon Pressure Verification ●
- Distensibility
- Tensile Testing of Joint Components
- Dimensional Verification (catheter and balloon)
- Functional Testing ●
- Shelf Life Testing ●
Biocompatibility testing was performed in accordance with the FDA Guidance, Use of International Standard ISO 10993-1, "Biological evaluation of medical devices-Part 1: Evaluation and testing within a risk management process" and per ISO 10993-1:2009, Biological evaluation of medical devices- Evaluation and testing within risk management process.
Conclusion
Results from design validation and/or verification testing provide reasonable assurance that the modifications do not raise new questions of safety or effectiveness. Therefore, we believe the subject device to be substantially equivalent to the predicate.
