Intended Use
The AXIOS Stent is indicated for use to facilitate transgastric or transduodenal endoscopic drainage of symptomatic pancreatic pseudocysts ≥6cm in size, and symptomatic Walled Off Necrosis ≥6cm in size, with ≥70% fluid content, that are adherent to the gastric or bowel wall. Once placed, the AXIOS stent functions as an access port allowing passage of standard and therapeutic endoscopes to facilitate debridement, irrigation and cystoscopy. The stent is intended for implantation up to 60 days and should be removed upon confirmation of pseudocyst or Walled Off Necrosis resolution.
Device Description
The AXIOS Stent and Delivery System and the AXIOS Stent and Electrocautery Enhanced Delivery System are discussed below and presented in Table 5 - 1 . There have been no changes to the AXIOS Stent or the delivery systems; it is identical to the stent and delivery systems cleared in 510(k) K152572 and K150692. AXIOS Stent: The AXIOS Stent and Delivery System is designed to secure the apposition of tissue, minimize stent displacement and create a large access/drainage lumen. AXIOS Non-Cautery Delivery System: The stent is preloaded within the AXIOS delivery catheter. The Delivery System consists of a catheter and an integrated handle with manual controls for positioning and deploying the AXIOS stent. The Delivery System is designed to be used in the gastrointestinal tract in conjunction with commercially available echoendoscopes with a 3.7 mm diameter or larger working channel and is compatible with commercially-available 0.035-inch insulated endoscopic guidewires. AXIOS Electro-Cautery Enhanced Delivery System: The stent is preloaded onto the AXIOS delivery catheter. The Electro-cautery Enhanced Delivery System consists of a catheter and an integrated handle with manual controls for positioning and deploying the AXIOS stent. The Electro-cautery Enhanced Delivery System is designed to be used in the gastrointestinal tract in conjunction with commercially available echoendoscopes with a 3.7 mm diameter or larger working channel and is compatible with commercially-available 0.035-inch insulated endoscopic guidewires.
More Information

No
The summary describes a mechanical stent and delivery system for draining pancreatic pseudocysts and Walled Off Necrosis. There is no mention of AI or ML in the device description, intended use, or performance studies.

Yes The device is a stent used to facilitate drainage and allow passage of endoscopes for debridement, irrigation, and cystoscopy for symptomatic pancreatic pseudocysts and Walled Off Necrosis, which are therapeutic interventions.

No

The device functions as an access port and drainage lumen for symptomatic pancreatic pseudocysts and Walled Off Necrosis. It facilitates debridement, irrigation, and cystoscopy; these are therapeutic actions, not diagnostic ones.

No

The device description clearly details a physical stent and delivery system, which are hardware components.

Based on the provided information, the AXIOS Stent is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This testing is done outside of the body.
  • AXIOS Stent Function: The AXIOS Stent is an implantable device used within the body to facilitate drainage of pancreatic pseudocysts and Walled Off Necrosis. It acts as an access port for endoscopic procedures.
  • Intended Use: The intended use clearly describes a procedure performed in vivo (within the body) to drain fluid collections.
  • Device Description: The description details a stent and delivery system designed for placement within the gastrointestinal tract.
  • Anatomical Site: The anatomical site is within the body (transgastric or transduodenal wall and into a pancreatic pseudocyst or Walled Off Necrosis).

The AXIOS Stent is a therapeutic device used in a surgical/interventional procedure, not a diagnostic test performed on a sample outside the body.

5. INDICATIONS FOR USE:

The AXIOS Stent is indicated for use to facilitate transgastric or transduodenal endoscopic drainage of symptomatic pancreatic pseudocysts ≥6cm in size, and symptomatic Walled Off Necrosis ≥6cm in size, with ≥70% fluid content, that are adherent to the gastric or bowel wall. Once placed, the AXIOS stent functions as an access port allowing passage of standard and therapeutic endoscopes to facilitate debridement. irrigation and cystoscopy. The stent is intended for implantation up to 60 days and should be removed upon confirmation of pseudocyst or Walled Off Necrosis resolution.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE 6. PREDICATE DEVICE:

There are no differences in the technological characteristics between the proposed device and the predicate AXIOS Stent with Delivery System (K152572) and AXIOS Stent with Electro-cautery Enhanced Delivery System (K150692). The purpose of this Traditional 510(k) is to request clarification to the AXIOS indication for use. The physical device will remain unchanged from the predicates K152572 and K150692, but the revision to the indication requires a change to the product labeling. All other design specifications remain unchanged. Tables 5-2 and 5-3 include a technological comparison of the proposed device against the predicate device.
