The summary describes a mechanical device (stent and delivery system) for drainage. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML. The performance studies focus on biocompatibility and mechanical function.
Yes
The device is indicated for use to facilitate transenteric endoscopic drainage of symptomatic pancreatic pseudocysts, which is a therapeutic intervention. It functions as an access port for further therapeutic procedures like debridement, irrigation, and cystoscopy.
No
The device is described as an endoscopic device designed to deliver a stent for drainage purposes, not for diagnosing conditions. Its function is to provide an access port and facilitate debridement, irrigation, and cystoscopy for symptomatic pancreatic pseudocysts.
No
The device description clearly outlines a physical stent and delivery system, which are hardware components. There is no mention of software as the primary or sole component of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological state, state of health, or disease or congenital abnormality.
- Device Function: The AXIOS™ Stent and Delivery System is a device used in vivo (within the body) to facilitate drainage of pancreatic pseudocysts. It is a physical implant and delivery system, not a test performed on a sample outside the body.
- Intended Use: The intended use clearly describes a surgical/interventional procedure to drain a pseudocyst and provide access for further procedures, not to diagnose a condition by analyzing a sample.
Therefore, the AXIOS™ Stent and Delivery System falls under the category of an implantable medical device used for treatment, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The AXIOS™ Stent and Delivery System is indicated for use to facilitate transenteric endoscopic drainage of symptomatic pancreatic pseudocysts ≥ 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 resolution.

(2) Performance data must demonstrate the sterility of patient-contacting components of the device.
(3) Performance data must support the shelf life of the device by demonstrating continued sterility, package integrity, and device functionality over the requested shelf life.
(4) Non-clinical testing data must demonstrate that the stent and delivery system perform as intended under anticipated conditions of use. The following performance characteristics must be tested:
(i) Deployment testing of the stent and delivery system must be conducted under simulated use conditions.
(ii) Removal force testing must be conducted. The removal force testing must demonstrate that the stent can be safely removed, and that the stent will remain in place when subjected to forces encountered during use.
(iii) Expansion force testing must be conducted. The expansion force must demonstrate that the forces exerted by the stent will not damage the tissue surrounding the stent.
(iv) Compression force testing must be conducted. The compression force must demonstrate that the stent will withstand the forces encountered during use.
(v) Dimensional verification testing must be conducted.
(vi) Tensile testing of joints and materials must be conducted. The minimum acceptance criteria must be adequate for its intended use.
(vii) Fatigue testing must be conducted. Material strength must demonstrate that the stent will withstand forces encountered during use.
(viii) Corrosion testing must be conducted. Corrosion resistance must demonstrate that the stent will withstand conditions encountered during use.

Principles of Operation: The AXIOS Delivery System is placed into the stomach through an endoscope that is passed through the patient's mouth and into an area of the stomach adjacent to the target pseudocyst. After creating a small opening in the wall of the stomach and a small opening in the pseudocyst, the physician positions the compressed stent across both openings, releases the stent and removes the delivery system. Once expanded, the stent allows the contents of the pseudocyst to drain into the stomach. When the pseudocyst has drained and decreased in size, the physician can use standard endoscopic tools to remove the AXIOS Stent.
Summary of Technological Characteristics: Comparison of materials used in the manufacture of the predicate and subject devices notes that the optional hydrophilic coating to be the only difference. The design and other technological characteristics are the same. No change was made to the AXIOS stent.
Determination of Substantial Equivalence: Substantial equivalence is supported through comparison with the predicate device: The AXIOS Stent and Delivery System. The subject device has the same intended use, utilizes the same principles of operations and fundamental scientific technology as that of the predicate device. No change was made to the AXIOS stent.
Non-clinical testing included biocompatibility testing, which was conducted in accordance with the FDA guidance entitled, "Required Biocompatibility Training and Toxicology Profiles for Evaluation of Medical Devices," dated May 1, 1995 (G95-1); as well as an comparison of tracking force with the predicate device.
Non-clinical testing confirmed the modified AXIOS Stent and Delivery Catheter is biocompatible, non-toxic and safe for temporary implantation. Bench testing of device function verified that the device meets product specifications, performance characteristics and requirements established by special controls for a pancreatic drainage stent and accessories.
Conclusions Drawn from Testing: Test results established that the specified performance levels were achieved and mitigations for anticipated risks were met through standard test methods, available guidances and recognized technical requirements. In conclusion, the modified device is as safe, as effective and performs as well as or better than the predicate AXIOS Stent and Delivery System.
