The Animas EZ Set Infusion set is intended to provide infusion of medicine, including insulin, from an external infusion pump. This device is intended for home use and is a prescription device.
The Animas EZ Set Infusion Set is an infusion adminstration set with the proximal end connecting to a medicine reservoir syringe within an infusion pump and the distal end inserted in the subcutaneous itssue of a user. The device consists of two components, an infusion site assembly and a tubing connector assembly. The infusion site assembly consists of a cannula housing with a disposable insertion hub assembly. The main body of the cannula housing has a thin self-adhesive pad for attachment to the skin. A soft flexible 22 gauge cannula extends below the flat bottom of the housing to penetrate the skin at a slight angle. A detachable insertion needle assembly is intitially connected to the cannula housing assembly to insert the soft flexible cannula subcutaneously. It is then removed and replaced by the needle hub assembly to deliver medication. An elastomeric septum seals the entrance to the cannula when the needle hub assembly is removed. The tubing connector assembly consists of a length of flexible plastic tubing made from polyvinyl chloride with a co-extruded polyethylene liner. The tubing is attached to a female Luer Lock connector at one end and a short needle mounted in the main body of the needle hub at the opposite end. The main body provides a means to align and attach the needle hub to the cannula housing assembly by means of a quick release connector. When the cannula housing and the needle hub are connected, the needle penetrates the septum allowing medication to flow from the pump through the flexible tubing, the needle, and the cannula into the patient's body. The needle hub assembly may be easily released from the cannula housing by squeezing the resilient side members deflecting the retaining band above a bump on the cannula housing. This allows the needle housing to slide freely off the cannula housing. The quick release connector allows the user to temporarily disconnect the tubing at the insertion site for activities such as dressing or bathing. In addition to complete administration sets, infusion site sets without the tubing i and quick release connector will also be available.
This document is a 510(k) premarket notification for the Animas EZ Set Infusion Set. It details the device's description, intended use, and comparison to predicate devices. However, it does not contain the acceptance criteria or a study proving the device meets those criteria, nor does it provide information on sample sizes, ground truth establishment, or expert involvement for performance evaluation studies.
The provided text is a regulatory submission for market clearance, not a clinical or performance study report. Therefore, most of the requested information regarding acceptance criteria and performance study details is not present in this document.
Here's a breakdown of why the requested information is absent and what can be inferred:
- Acceptance Criteria and Reported Device Performance: This document states the device is "substantially equivalent" to predicate devices. This means the FDA has determined it performs as intended and is as safe and effective as devices already on the market. However, specific quantifiable performance metrics and acceptance criteria tested in a study are not included. The focus is on similarity in design and intended use.
- Sample Size, Ground Truth, Experts, Adjudication, MRMC studies, Standalone Performance: These are elements of a performance study. A 510(k) submission often references such studies or provides summaries if they were conducted for claims of substantial equivalence. This particular document, however, does not detail any such specific performance studies.
- For a device like an infusion set, performance criteria would typically relate to:
- Flow rate accuracy and consistency
- Leakage prevention
- Insertion force and patient comfort
- Durability and connection integrity
- Biocompatibility
- Sterility
- These would be evaluated through various engineering tests, bench tests, and potentially limited human use studies if new claims were being made. The document implies these tests were done to support the "substantial equivalence" claim, but the details are not provided.
- For a device like an infusion set, performance criteria would typically relate to:
- Training Set and Ground Truth for Training Set: Since no algorithm or AI component is mentioned, there would be no training set in the context of an AI/ML device.
What can be extracted from the document is limited to regulatory information:
- Device Name: Animas EZ Set Infusion Set
- Predicate Devices: MiniMed Paradigm Silhouette Infusion Set, Maersk Medical Comfort Infusion Set, Disetronic Tender Infusion Set
- Intended Use: For infusion of medicine, including insulin, from an external infusion pump, for home use, and a prescription device.
- Regulatory Conclusion: The FDA determined the device is "substantially equivalent" to legally marketed predicate devices.
In summary, the provided text does not contain the specific performance study information (acceptance criteria, sample sizes, ground truth, expert details, etc.) you are requesting because it is a regulatory clearance document focused on demonstrating substantial equivalence, not a detailed technical report of a performance study. Such study details would typically be found in accompanying technical reports or clinical trial summaries, which are not part of this 510(k) summary.
§ 880.5440 Intravascular administration set.
(a)
Identification. An intravascular administration set is a device used to administer fluids from a container to a patient's vascular system through a needle or catheter inserted into a vein. The device may include the needle or catheter, tubing, a flow regulator, a drip chamber, an infusion line filter, an I.V. set stopcock, fluid delivery tubing, connectors between parts of the set, a side tube with a cap to serve as an injection site, and a hollow spike to penetrate and connect the tubing to an I.V. bag or other infusion fluid container.(b)
Classification. Class II (special controls). The special control for pharmacy compounding systems within this classification is the FDA guidance document entitled “Class II Special Controls Guidance Document: Pharmacy Compounding Systems; Final Guidance for Industry and FDA Reviewers.” Pharmacy compounding systems classified within the intravascular administration set are exempt from the premarket notification procedures in subpart E of this part and subject to the limitations in § 880.9.
