The PercSys Accordion® Stone Management Device is intended to be used in endoscopic procedures to bypass, entrap and remove calculi and other foreign objects from the urinary tract, to prevent retrograde migration of calculi during lithotripsy, and to guide instrumentation within the ureter.
The Accordion device consists of a film membrane preloaded onto a two-part wire guide with a removable handle. The device is advanced within the urinary system similar to a wire guide, then, once the film membrane is in the desired position, the film folds into a helical coil (a film-based occlusion) which occupies the lumen of the anatomy in which it resides. In this manner, the occlusion limits migration of stones and stone fragments during lithotripsy. The shaft of the device is 0.97mm (0.038 inch) in outer diameter, has a 150 cm working length, and the film occlusion can be formed into either a 7 mm or 10 mm diameter helical coil. The device is visible under fluoroscopic imaging due to marker bands on either side of the film component and radiopaque disc embedded in the film. The Accordion device is provided sterile and is a single-use only device.
The provided text is a 510(k) summary for a medical device (PercSys Accordion® Stone Management Device) and details its intended use, description, and substantial equivalence to predicate devices. It does not contain information about specific acceptance criteria, device performance metrics, or details of a study that explicitly proves the device meets such criteria.
The document states: "Bench top and clinical data from the literature were submitted in support of the proposed performance claims for this 510(k) submission, as well as in support of documenting that the changes in device materials and sterilization method has not affected design specifications." and "The bench top and clinical data show the Accordion device is as safe and as effective as the predicate devices and support the proposed advertising claims."
However, it does not provide the details of this data, making it impossible to answer the specific questions regarding acceptance criteria, sample sizes, ground truth establishment, or clinical study methodologies.
Therefore, I cannot populate the table or answer the specific questions as the required information is not present in the provided text.

Intended Use
The PercSys Accordion® Stone Management Device is intended to be used in endoscopic procedures to bypass, entrap and remove calculi and other foreign objects from the urinary tract, to prevent retrograde migration of calculi during lithotripsy, and to quide instrumentation within the ureter.
Device Description
The Accordion device consists of a film membrane preloaded onto a two-part wire guide with a removable handle. The device is advanced within the urinary system similar to a wire guide, then, once the film membrane is in the desired position, the film folds into a helical coil (a film-based occlusion) which occupies the lumen of the anatomy in which it resides. In this manner, the occlusion limits migration of stones and stone fragments during lithotripsy. The shaft of the device is 0.97mm (0.038 inch) in outer diameter, has a 150 cm working length, and the film occlusion can be formed into either a 7 mm or 10 mm diameter helical coil. The device is visible under fluoroscopic imaging due to marker bands on either side of the film component and radiopaque disc embedded in the film. The Accordion device is provided sterile and is a single-use only device.
Performance Data
Bench top and clinical data from the literature were submitted in support of the proposed performance claims for this 510(k) submission. as well as in support of documenting that the changes in device materials and sterilization method has not affected design specifications.
Substantial Equivalence
The subject of this 510(k) is the device that was cleared under K052048 (with a few modifications) and is equivalent in technology and intended use to the Stone Cone (K864874). Both the Accordion and Stone Cone devices have a component to reduce migration of stones and stone fragments during lithotripsy. Both are advanced via the working channels of endoscopes and can be used in either ureteroscopic cases (advanced retrograde) or percutaneous nephrolithotomy cases (advanced antegrade). The antiretropulsion component of the Accordion device is a film, while that of the Stone Cone is a wire spiral. The main purpose of this 510(k) submission is to obtain clearance of performance claims to be used in labeling.
Conclusions
The bench top and clinical data show the Accordion device is as safe and as effective as the predicate devices and support the proposed advertising claims.

Dear Dr. Lawson:
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 may, therefore, market the device, subject to the general controls provisions of the Act.
