No
The summary describes a standard infusion pump with a micro-dosing mechanism and acoustic volume sensor feedback. There is no mention of AI, ML, or any related technologies in the device description, intended use, or performance studies.
Yes
The device is intended for continuous subcutaneous delivery of Remodulin® (treprostinil) Injection for the treatment of pulmonary arterial hypertension (PAH), which is a medical therapy.
No
Explanation: This device is described as an infusion pump designed for continuous subcutaneous delivery of medication (Remodulin). Its function is to administer treatment, not to diagnose a condition.
No
The device description explicitly lists several hardware components including a wearable pump assembly, a remote interface, a filling and priming aid, rechargeable batteries, battery charging cable, and power adapter. It also mentions a disposable single-use cassette reservoir and a micro-dosing pump mechanism.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is the "continuous subcutaneous delivery of Remodulin® (treprostinil) Injection". This describes a device that delivers a therapeutic substance to the body.
- Device Description: The description details a "wearable infusion pump designed to deliver Remodulin®". It focuses on the mechanism of delivery, the components involved in that delivery (pump, cassette, infusion set), and the process of filling and using the cassette.
- Lack of Diagnostic Function: There is no mention of the device being used to examine specimens from the human body to provide information for the purpose of diagnosis, monitoring, or screening. IVDs are typically used to test blood, urine, tissue, or other bodily fluids or substances.
This device is clearly a therapeutic device, specifically an infusion pump, used to administer medication.

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® (treprostinil) (hereinafter referred to as 'Remodulin' or 'Remodulin (treprostinil)'). 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 subcutaneous 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 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.
Cassettes are identical to those cleared under K190182, with the specialty pharmacy will take the cassettes out of their sterile packaging, cap the cassette and aseptically fill the cassette reservoir through the cassette filling septum following USP 797 Compounding Sterile Preparations. The specialty pharmacy will then package these filled cassettes and ship to the intended end user under controlled conditions outlined in the labeling. The pharmacy-filled cassette is intended to be stored (inclusive of shipping item) up to 14-days and is intended to be in use for up to 72-hours.
The device is prescription use only.

Summary of Performance Studies
The following performance data/non-clinical testing was provided in support of the substantial equivalence determination for the Unity System.
A safety assurance case was provided for the Unity Subcutaneous Delivery System for Remodulin, as recommended in the FDA guidance document, Infusion Pumps Total Product Life Cycle.
The stated goal of the safety assurance case is: "The Unity Remodulin Subcutaneous Infusion System is adequately safe for its intended use."
The assurance case defined the device system, including the indications for use, system definition, operational description, patient populations, and use environments. The context for the assurance case was updated to reflect the new use scenario of pharmacy filled cassettes. The supporting assurance arguments covered the following attributes:
- All hazards associated with the system have been identified and adequately addressed
- Device reliability is adequate
- The device design requirements are adequately verified and validated
The arguments were updated from the original assurance case presented in predicate, K190182, to reflect new hazards and requirements associated with the changes.
The following specific evidence was included within the assurance case to demonstrate that the subject device is verified and validated for its intended use and to demonstrate substantial equivalence to the predicate devices.
Since the assurance case builds on the original case, only evidence used to provide assurance related to the changes is listed here:
- Accessory compatibility: Verification of the pump essential performance was completed with labeled administration sets
- Device performance: The essential performance requirements of the device were verified through performance testing in accordance with the intended use of the device and in accordance with the FDA Guidance "Infusion Pumps Total Product Life Cycle" Performance of the device to maintain adequate assurance of drug stability, and protection from microbial ingress was evaluated through drug stability studies, container closure integrity and antimicrobial effectiveness testing. The testing was done to represent 14 days + 72 hours of in-use at a minimum.
- Human Factors: Human factors evaluation per the FDA Guidance Applying Human Factors and Usability Engineering to Medical Devices (February 3, 2016).
- Reprocessing, Cleaning, Sterility: ISO 11137-1:2006 + A1:2013 Sterilization of health care products - Radiation - Part 1: Requirements for development, validation and routine control of a sterilization process for medical devices ISO 11607-1:2006 + A1:2014 Packaging for terminally sterilized medical devices - Part 1: Requirements for materials, sterile barrier systems and packaging systems Validation per the FDA Guidance for Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling (March 17, 2015) confirmed cleaning and disinfection instruction provided in instructions for use
- Biocompatibility: The materials used for the Unity System comply with biocompatibility requirements outlined in ISO 10993-1:2009 and the Guidance for Industry and Food and Drug Administration Staff, Use of International Standard ISO 10993 Biological Evaluation of Medical Devices Part 1: Evaluation and Testing within a Risk Management Process are considered to be biocompatible.
No clinical data was obtained in support of this premarket submission.
