No
The document describes a balloon dilation catheter and its use with an imaging system, focusing on mechanical dilation and measurement. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The device is a balloon catheter used to dilate esophageal strictures, which directly treats a medical condition.
No
The device is a balloon catheter used to dilate esophageal strictures. While it connects to an "imaging system" to display cross-sectional areas during dilation, its primary function is therapeutic (dilation), not diagnostic (identifying or characterizing a disease).
No
The device is a balloon catheter, which is a physical medical device used for dilation. While it connects to a system that likely includes software, the device itself is hardware.
Based on the provided information, the EsoFLIP® ES-310 balloon catheter is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- EsoFLIP® ES-310 Function: The EsoFLIP® ES-310 is a therapeutic device used to physically dilate esophageal strictures. It is inserted into the body and performs a mechanical action.
- Intended Use: The intended use clearly states it is for "use to dilate esophageal strictures." This is a treatment, not a diagnostic test performed on a specimen.
- Device Description: The description confirms it is a "balloon dilation catheter" used by surgeons or gastroenterologists to "dilate esophageal strictures."
- No Specimen Analysis: There is no mention of the device analyzing any biological specimens. It interacts directly with the patient's anatomy.
While the device is used with the EndoFLIP® system which displays an image and measures cross-sectional areas, this is part of the procedure to guide and monitor the dilation, not a diagnostic test performed on a specimen.
Therefore, the EsoFLIP® ES-310 balloon catheter falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

Device Description:
The EsoFLIP® ES-310 catheter is a balloon dilation catheter. It is used by surgeons or gastroenterologists to dilate esophageal strictures due to esophageal surgery, primary gastroesophageal reflux, and radiation therapy. This indication for use is identical to the predicate EsoFLIP® ES-series (ES-320) predicate, K142000.
The EsoFLIP® catheter connects to the EndoFLIP® imaging system in the same fashion as the predicate EsoFLIP® catheter, to display an image of the cross-sectional-areas (CSAs) of the dilation balloon, and to allow the balloon to be inflated using the EndoFLIP® syringe driver.
In all cases the catheters are to only be used with the EndoFLIP® system.
Modifications of these devices vs. Predicates:
The following is a summary of the differences between the proposed EsoFLIP® ES-310 catheter and the predicate EsoFLIP® ES-series (ES-320) catheter, cleared under K142000.
- (1) Change of the balloon size for use in smaller strictures.
- a. This of course affects the working specifications of the balloon
- b. Measurement range, Reading Length, Working Length, Maximum Filling Volume
- (2) Has diameter measurements (Sensors) at 8 points vs. the ES-320 (K142000) at 16 points
- a. Other EndoFLIP® catheters have been cleared with 8 sensors (BF-325N -K130906)
4
- Maximum Balloon Inflation Pressure 1.5 ATM (3)
The EsoFLIP® ES-310 balloon dilation catheter is used exclusively with the EndoFLIP® system. The user interface is unchanged.
Indications for Use:
The EsoFLIP® ES-310 balloon catheter is indicated for use to dilate esophageal strictures due to esophageal surgery, primary gastro-esophageal reflux and radiation therapy.
Note: The EsoFLIP® ES-310 catheter is to be used only with the EndoFLIP® system.
| Patient Population: | Patient population is patients with strictures |
|---|---|
| Environment of Use: | Hospitals and Surgery Centers |
Contraindications:
The EsoFLIP® ES dilation catheter is contraindicated where:
- (1) endoscopy is contraindicated,
- (2) with actively bleeding varices and
- (3) for diameter measurements and dilation of strictures smaller than 6mm or greater than 10mm
Predicate Device Comparison:
Table 1 compares the EsoFLIP® ES-310 catheter to the predicate Crospon EsoFLIP® ES-series (ES-320) (K142000) and the references.
The EsoFLIP® ES-310 dilation catheter is viewed as substantially equivalent to the predicate -Crospon EsoFLIP® ES -series (ES-320) cleared under K142000 because:
Indications -
The dilation indications for use are identical to the predicate K142000. Discussion - The indications for use for the proposed device does not change from the predicate Crospon EsoFLIP® ES-series, K142000.
Patient Population -
The patient populations are identical, specifically indicated for patients requiring dilation of esophageal strictures.
Discussion – The patient population is unchanged and identical to the predicate Crospon EsoFLIP® ES-series, K142000. However, the diameter of strictures that the ES-310 dilation catheter is intended to be used with is smaller (6 to 10 mm).
Environment of Use -
The environments of use - hospital and surgery centers - are identical to the predicate. Discussion - The environments of use are identical to the predicate Crospon EsoFLIP® ESseries. K142000.
5
Contraindications -
The contraindication related to minimum and maximum diameters of strictures that the catheter may be used with has been updated to reflect the proposed ES-310's smaller balloon size. Discussion - The contraindications are identical with exception of the update of sizing to the predicate Crospon EsoFLIP® ES-series, K142000.
Technology -
The EsoFLIP® Des measurement technology, construction, and design are unchanged from the EsoFLIP® ES-series catheter, K142000, when used with the EndoFLIP® system as cleared under K160725.
Discussion - The diameter measurement technology is unchanged from the predicate. The proposed EsoFLIP® ES-310 catheter measures diameter at 8 points, whereas the predicate K142000 measures at 16 points. However, Crospon has clearance for catheters which measure at 8 points, namely BF-325N, K130906.
The dilation technology of the EsoFLIP® ES catheter: maximum diameter and balloon working length, is similar to the predicate Crospon ES-series (ES-320) K142000.
The maximum inflation pressure of 1.5 ATM is identical to that of the reference Crospon EsoFLIP® ES-330 (K132337). While different from the predicate, which has a maximum inflation pressure of 2 ATM, Crospon has clearance for a catheter with a 1.5 ATM maximum inflation pressure that has a similar intended use.
Non-clinical Comparative Performance and Specifications -
Bench Testing -
The Performance Testing included -
- Balloon Fatigue testing
- Balloon Compliance testing ●
- Balloon Burst test
- . Catheter Assembly test
- Diameter measurement accuracy testing .
Other testing was leveraged from the predicate. The testing demonstrated that the proposed EsoFLIP® ES-310 Balloon Dilation Catheter performed to its specifications (dilation and measurement) and thus is substantially equivalent to the predicate devices.
Biocompatibility-
The materials in contact with the patient are identical to the predicate, EsoFLIP® ES-series (K142000).
Discussion - The materials are unchanged from the predicate.
Discussion of Differences
The differences between the proposed and predicate device relate to:
- Size of balloon ●
- This does not alter population or indications for use. It allows the clinician a o smaller size for use with their patients
- Contraindication ●
6
510(k) Summary Page 4 of 6 20-Nov-17
- The change is only with the dimensions. Otherwise the contraindications are o identical
- Maximum inflation pressure
- Crospon has clearance for inflation at 1.5 ATM vs. the predicate at 2.0 ATM O
- . Number of Sensors
- o The subject device has 8 sensors. The K130906 BF-325N also has 8 sensors.
All of the differences have been cleared under previous 510(k) except the balloon size, which is only being offered for the clinician who requires a smaller size. These changes do not alter the indications for use, patient population, environments of use, technological characteristics, contraindications, or performance specifications. The differences do not raise new concerns of safety or effectiveness.
Substantial Equivalence Conclusion -
The sponsor has demonstrated through performance testing, design and features, and non-clinical testing that the proposed device does not raise any new safety concerns compared to the predicates.
