Intended Use
The Unity Subcutaneous Delivery System for Remodulin® (the Unity System) is intended for continuous subcutaneous delivery of Remodulin (treprostinil) injection for use in adults (greater than 22 years of age).
Device Description
The Unity Subcutaneous Delivery System for Remodulin® (Unity System) is a wearable infusion pump designed to deliver Remodulin® for the treatment of pulmonary arterial hypertension (PAH). It is intended for continuous subcutaneous delivery of FDA-approved Remodulin® (treprostimil) (hereinafter referred to as 'Remodulin (treprostinily), NDA 021272. The Unity System consists of several components: a wearable pump assembly, a remote interface, a filling and priming aid, and accessories (e.g., rechargeable batteries, battery charging cable, power adapter). A commercially available subcutaneous infusion set is connected to the pump assembly via a standard Luer connector for the delivery of Remodulin from the Unity System to the patient. The pump assembly is composed of a reusable pump and a disposable single-use cassette with a user-filled drug reservoir, which infuses Remodulin subcutaneously into the patient based on an individualized programmed rate. Each disposable cassette may be used for up to 72 hours after attachment to the pump. The Unity System utilizes a micro-dosing pump mechanism supplemented with acoustic volume sensor feedback to ensure delivery accuracy. The device is prescription use only.
More Information

No reference devices are used in this submission.

No
The document describes a standard infusion pump with sensor feedback and programmable rates, but there is no mention of AI or ML algorithms for decision-making, data analysis, or adaptive control.

Yes
Explanation: The device is designed to deliver a drug (Remodulin) to treat a medical condition (pulmonary arterial hypertension), which directly contributes to therapy.

No
The device is described as an infusion pump, designed to deliver medication, not to diagnose a condition.

No

The device description explicitly states that the Unity System consists of several hardware components, including a wearable pump assembly, a remote interface, a filling and priming aid, and accessories. It also mentions a micro-dosing pump mechanism and an acoustic volume sensor. This indicates it is a hardware device with integrated software, not a software-only medical device.

No, this device is not an IVD (In Vitro Diagnostic).

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 (in vitro).
  • Unity System Function: The Unity Subcutaneous Delivery System is an infusion pump designed to deliver a drug (Remodulin) into the patient's body (subcutaneously). It is a therapeutic device, not a diagnostic one.

The provided information clearly describes a drug delivery system, not a device used for testing biological samples.

Identification. An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.(b)

Clinical Testing

A clinical study was conducted to support the substantial equivalence of the device and to clinically validate the Acoustic Volume Sensor (AVS) design. The Performance Assessment of The Unity Infusion System with 0.9% Sodium Chloride Injection in Healthy Volunteers study was conducted to establish evidence that the AVS measurement process consistently produces results within an acceptable, predetermined measurement uncertainty. All participants were healthy subjects between 18 and 55 years of age, inclusive, at the time of informed consent.

Objective

The objective of this study was to assess the performance of the Unity System to deliver 0.9% sodium chloride (normal saline [NS]) by subcutaneous (SC) infusion to healthy volunteers by assessing the following:

10

  • In vivo infusion delivery accuracy assessed by measured volumetric flow rate compared to programmed flow rate of the Unity System to demonstrate environmental noise of other elements of daily use interfered with the ability of the Unity System to deliver accurately when participants were challenged to loud sound exposures.
  • . In vivo the Unity System reliability assessed by device history logs (flow rate, malfunctions, etc.) and subject diaries (environmental exposures)

Criteria for Evaluation

Pump Performance: In vivo infusion delivery accuracy was assessed by measured volumetric flow rate compared to programmed flow rate of the Unity System. In vivo Unity System reliability was assessed by device history logs (flow rate, malfunction, complications, etc.) and subject diaries (environmental exposures).

Safety: Per protocol, all adverse events (AEs), serious adverse events (SAEs), and unanticipated adverse device effects (UADEs) were to be documented from Baseline until the subject was either discontinued from the study or all End of Infusion study assessments were complete. All AEs associated with a device complication were to be investigated.

Conclusions

Pump Performance: The study successfully demonstrated that the majority of measured data fell within the accuracy specification. There were brief intervals (less than six how rate measured was outside the performance specification limit for under delivery (-6%). Each of these intervals were within the measurement uncertainty of the measure equipment used in the study or associated with the delivery of air bubbles, and all were within 25%. The study found no evidence of environmental noise or other elements of daily use interfered with the ability of the Unity System to deliver accurately.

Safety: No safety concerns related to use of the Unity System were identified during this study.

Conclusion

Differences between the intended use and technological characteristics of the subject device compared to the predicate do not raise different questions of safety and effectiveness. The device is supported by non-clinical testing, clinical testing, and risk management activities. The Unity Subcutaneous Delivery System for Remodulin is Substantially Equivalent (SE) to the CADD-MS 3 Ambulatory Infusion Pump, cleared under K051568.
