Regulatory Classification

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.

### Predicate Device(s)

The predicate device is the Remunity Subcutaneous Delivery System for Remodulin®, which was previously cleared under premarket application K202690 on December 30, 2020.

### 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

{5}------------------------------------------------

Image /page/5/Picture/0 description: The image shows the word "DEKA" in a bold, sans-serif font. The letters are all capitalized and black. The "K" in the word is stylized with an arrow shape in the middle.

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.

The pump assembly is composed of a reusable pump and a disposable single-use cassette with a pharmacy-filled or 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 Remunity System utilizes a micro-dosing pump mechanism supplemented with acoustic volume sensor feedback to ensure delivery accuracy.

The device is prescription use only.

The modified device utilizes a touchscreen remote controller.

### Indications for Use

The Remunity® Pump for Remodulin® (treprostinil) Injection (the Remunity System) is intended for continuous subcutaneous delivery of Remodulin (treprostinil) Injection for use in adults (greater than 22 years old).
