Intended Use

Zimmon® Pancreatic Stents/Stent sets (SPSOF, SPSOS, ZEPDF, ZPSOF, ZPSOS); Geenen® Pancreatic Stents/ Stent Sets (GEPD, GPDS, GPSO, GPSOS); Geenen® Sof-Flex® Pancreatic Stent (GPSO-SF. GPSOS-SF); Endoscopic pancreatic stent placement is used for pancreatic drainage that could be caused by pancreatitis, stricture, pancreatic cancer, anatomic anomalies of the pancreas, pancreatic fluid collection, pancreatic stones, disrupted duct, fistula/pancreatic leak. Pancreatic stents are also used prophylactically for prevention of post-ERCP pancreatitis.

Johlin® Pancreatic Wedge Stent and Introducer Set (JPWS): Endoscopic pancreatic stent placement for pancreatic drainage of obstructed ducts that could be caused by pancreatitis, stricture, pancreatic cancer, anatomic anomalies of the pancreas, pancreatic fluid collection, pancreatic stones, and disrupted duct.

Pushing Catheter and Guiding Catheter (GC, PC): These devices are indicated for use with biliary and pancreatic stents for the following indications. For endoscopic biliary stent placement for biliary drainage of obstructed ducts that could be caused by common bile duct stones, malignant biliary obstruction and benign or malignant strictures. For endoscopic pancreatic stent placement for pancreatic duct drainage that could be caused by pancreatitis, stricture, pancreatic cancer, anatomic anomalies of the pancreatic fluid collection, pancreatic stones, disrupted duct, fistula / pancreatic leak. Pancreatic stents are also used prophylactically for prevention of post-ERCP pancreatitis.

Device Description

The intended use of all Cook pancreatic stents and sets is to drain pancreatic ducts. A variety of stents in different sizes are available across the device range to accommodate various patient anatomies, the size and location of the obstruction and physician preference. They are offered in French sizes of between 3Fr and 11.5Fr, and in labelled lengths of between 2cm and 25cm.The subject devices and their components can be supplied as stent only, introducer only (guiding or pushing catheter) or as stent sets combining stent and introducers/introducer systems.

The stent sets can contain one or several of the following stent placement components; a flap protector, a guiding catheter, a pushing catheter or a dedicated introducer system. The flap protector is provided with stents that have duodenal flap-type anti-migration features, and is used to collapse the flap(s) on the device as it is introduced into the working channel of the endoscope. The function of the guiding catheter is to guide the pancreatic stent as part of its introduction to its intended location. The guiding catheter also has a Hub that allows for contrast injection. The function of the Pushing Catheter is to advance the stent, over a pre-positioned wire guide or Guiding Catheter, to its intended location within the anatomy, and to maintain the position of the Stent as it being deployed. The stents are polymeric and some of the stents have radiopaque bands. The stent designs include anti-migrational features such as duodenal pigtails, duodenal bends and ductal and duodenal flaps. To facilitate stent insertion and removal the stent ends are tapered or buffed. Side-ports on the pancreatic stents assist in drainage. All stents are deployed endoscopically over a guide wire in the same manner under fluoroscopic and endoscopic monitoring.

These Cook pancreatic stents and sets are all for professional use and are provided sterile. They are all intended for short-term use and have an indicated indwell of up to 3 months.

AI/ML Overview

The provided document (K233079) describes the Cook Ireland Ltd. Zimmon and Geenen Pancreatic Stents/Stent sets, Johlin Pancreatic Wedge Stent and Introducer Set, and Pushing and Guiding Catheters. This submission is for medical devices, not an AI/ML powered device, therefore, the information requested in the prompt related to acceptance criteria and studies that prove the device meets these criteria is not applicable in the context of AI/ML performance.

Specifically, the document focuses on demonstrating substantial equivalence to a predicate device (Pancreatic Stents & Sets cleared under K172057) through comparisons of technological characteristics and non-clinical performance data. There is no mention of acceptance criteria related to AI/ML device performance metrics like sensitivity, specificity, or AUC, nor any studies involving test sets, ground truth established by experts, or human reader performance with or without AI assistance.

The performance data mentioned in the document are:

  • Biocompatibility evaluation: Conducted in accordance with ISO 10993-1: 2018 and FDA's biocompatibility guidance.
  • Performance testing: Included simulated use, dimensional and visual testing, tensile strength testing, MRI conditional testing, radiopacity, flow rate, and shelf-life testing.

These tests aim to ensure the physical and material integrity, safety, and functionality of the pancreatic stents and catheters.

Therefore, I cannot provide the requested information in the format of the table or answer the specific questions related to AI/ML acceptance criteria and studies based on the provided text.

§ 876.5010 Biliary catheter and accessories.

(a)
Identification. A biliary catheter and accessories is a tubular flexible device used for temporary or prolonged drainage of the biliary tract, for splinting of the bile duct during healing, or for preventing stricture of the bile duct. This generic type of device may include a bile collecting bag that is attached to the biliary catheter by a connector and fastened to the patient with a strap.(b)
Classification. Class II (special controls). The device, when it is a bile collecting bag or a surgical biliary catheter that does not include a balloon component, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.
