DepotOne is a sterile single use hypodermic single lumen needle intended for the injection and removal of fluids from below the surface of the skin in humans.
DepotOne is a sterile hypodermic single lumen needle intended for the injection and removal of fluids from below the surface of the skin in humans. The needle is intended to interface with the male luer connector of a syringe or intravascular administration set. The needle is intended for single use only.
The DepotOne needles comprise of a length of Hypodermic grade stainless steel tube connected to a female connector (hub) that is designed to mate with a male connector of a piston syringe or an intravascular administration set. The other end of the tube is sharpened with a lancet tip in accordance with ISO7864: 1993. The sharpened section of tube is of a reduced diameter. The fluid is injected or removed through a side aperture adjacent to the sharpened tip.
The acceptance criteria and study proving the DepotOne™ device meets these criteria are detailed in the provided 510(k) submission.

2. Sample Size Used for the Test Set and the Data Provenance
The document does not explicitly state the numerical sample sizes for each test mentioned (e.g., how many needles were subjected to bend, breakage, or bond tests). It only states that "DepotOne™M needles have passed the following tests" or "DepotOne™ needles have been subjected to and passed the following tests."
The data provenance is from prospective testing conducted by Imprint Pharmaceuticals Ltd. and independent laboratories on the DepotOne™ device itself. The country of origin for the testing facilities is not explicitly stated, but Imprint Pharmaceuticals is based in Surrey, UK.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
This information is not applicable to this type of device submission. The "ground truth" for hypodermic needles is established by compliance with international engineering and sterilization standards (e.g., ISO, EN, Pharmacopoeia) and validated laboratory testing, not by expert consensus on clinical interpretation or outcomes in the same way as, for example, an imaging diagnostic device. The expertise lies in engineering, materials science, microbiology, and quality assurance.
4. Adjudication Method for the Test Set
This information is not applicable. Adjudication methods are typically relevant for studies involving human interpretation (e.g., reading images), which is not the case for the physical and biological testing of a hypodermic needle. The "adjudication" is inherent in whether the device objectively passes or fails the specified criteria of the international standards.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
This information is not applicable, as the device is a hypodermic needle and not an AI-enabled diagnostic or interpretive tool.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
This information is not applicable, as the device is a hypodermic needle and does not involve AI algorithms.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for this device is based on International Standards and validated laboratory test results. This includes:
- Engineering specifications for materials, dimensions, and physical properties (e.g., bend, breakage, bond strength, fluid flow, penetration force).
- Biological safety and sterility standards (e.g., SAL of 10-6, pyrogenicity, residual gas content).
These standards and test methods serve as the objective "truth" against which the device's performance is measured.
8. The Sample Size for the Training Set
This information is not applicable, as the device is a physical hypodermic needle and does not involve an AI algorithm or a "training set" in the context of machine learning.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable, as there is no "training set" for this device.

{1}------------------------------------------------
Design & Materials:
DepotOne and K-Pack II needles are manufactured from stainless steel hypodermic grade tube.
The tip of DepotOne™ is reduced in diameter. An opening is ground into the side of the tube close to the sharpened tip to facilitate the delivery or removal of the fluids. The tip diameter of the K Pack II needle is not reduced, the opening is in the tip. Both needles are sharpened at the tip in accordance with ISO7864.
The proximal end of both needles is securely attached to a 6% Luer connector by means of an epoxy adhesive. The Luer connector is a locking fitting and is in accordance with ISO 594-2 (the K-Pack needle Luer connector does not completely meet the requirements of ISO 594-2). The connector is colour coded in accordance with ISO 6009.The DepotOne connector is manufactured from polycarbonate. The material differs from the material used in the predicate devices and was selected for its superior bond strength when glued. The difference in the materials does not have any impact on the sterilisation. The polycarbonate used in the manufacture of the hub is approved for EO and gamma sterilisation by the manufacturer.
Both needles are supplied fitted with a rigid moulded polypropylene needle tip protector (shield). The colour of this moulding is clear.
Both needles are sterilised using ethylene oxide (ETO).
The difference between DepotOne and the predicate device do not raise any significant issues of safety and effectiveness and do not affect the substantial equivalence.
