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. ## Predicate Devices - Unity Subcutaneous Delivery System for Remodulin ([K191313](/device/K191313.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

No reference devices are used in this submission. #### Device Description The Remunity Subcutaneous Delivery System for Remodulin® (Remunity 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 Remunity System consists of several components: a wearable pump assembly, a remote interface, a filling and priming aid, and accessories (e.g., rechargeable batteries, battery charger, 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 Remunity System to the patient. {4}------------------------------------------------ The pump assembly is composed of a reusable pump and a disposable single-use cassette with a pharmacy-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 Remunity System utilizes a micro-dosing pump mechanism supplemented with acoustic volume sensor feedback to ensure delivery accuracy. The pharmacy-filled cassette is intended to be stored (inclusive of shipping time) up to 14-days and is intended to be in use for up to 72-hours. The cassettes are identical to those cleared under K191313, with the exception that the luer lock cap material was changed from Polycarbonate to ABS. The device is prescription use only. # Indications for Use The Remunity Subcutaneous Infusion System (the Remunity System) is intended for continuous subcutaneous delivery of Remodulin® (treprostinil) Injection for use in adults (greater than 22 years of age). ## Substantial Equivalence Discussion ## Intended Use Comparison The table below includes a summation matrix of the intended use between the new device and those of the current device: | Characteristic | Unity Subcutaneous Deliver

The stated goal of the safety assurance case ("safety case") is: "The Remunity Subcutaneous Infusion System for Remodulin® 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 assurance case was updated to reflect the new luer lock cap material and continues to cover all system attributes that were stated for the predicate: - 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 specific to the luer lock cap material change were updated from that of the predicate K191313. Since the assurance case builds on the original case, only evidence used to provide assurance related to the changes are listed here: | Container Closure
performance | Performance of the device to maintain adequate assurance of
protection from microbial ingress was evaluated through container

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" and are considered to be biocompatible. | {10}------------------------------------------------ ## Clinical Study No clinical data was obtained in support of this premarket submission. #### Design Control The Remunity System was specified and developed by DEKA. DEKA is a registered medical device specification developer and complies with the FDA Quality System Regulation as specified in 21 CFR 820, as well as registered to ISO 13485. #### Conclusion The modifications in the luer lock cap material do not change the intended use or technological characteristics of the subject device compared to the Unity System cleared under premarket notification K191313. The changes summarized in this submission do not raise different questions of safety and effectiveness. The performance of the device is supported by DEKA's design control process which included non-clinical testing and risk management activities. The Remunity Subcutaneous Delivery System for Remodulin® is Substantially Equivalent (SE) to the Remunity Subcutaneous Delivery System for Remodulin® cleared under premarket notification K191313. --- **Source:** [https://fda.innolitics.com/submissions/HO/subpart-f%E2%80%94general-hospital-and-personal-use-therapeutic-devices/QJY/K202690](https://fda.innolitics.com/submissions/HO/subpart-f%E2%80%94general-hospital-and-personal-use-therapeutic-devices/QJY/K202690) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
