Indications for Use

The Accuryn Monitoring System is intended for use in the drainage and/or collection of urine, and in the monitoring of urine output and core body temperature, in degrees Celsius. The Accuryn Monitoring System is also intended for use in the monitoring of intra-abdominal pressured pressures can be used as an aid in the diagnosis of intra-abdominal hypertension (IAH) and the associated clinical syndrome of abdominal compartment syndrome (ACS). The Accuryn Sensing Urinary Catheter is a single use device intended for short-term use (less than 30 days).

Device Story

Accuryn Monitoring System comprises a 16 French, 4-lumen silicone sensing urinary catheter, urine collection set, and monitor. Catheter inputs: bladder urine (drainage), thermistor (temperature), and closed air column (intra-abdominal pressure). Monitor transforms air column pressure signals via internal transducer and thermistor signals into digital displays of urine output, core temperature, and intra-abdominal pressure. Used in clinical settings by healthcare providers to aid diagnosis of IAH and ACS. System provides real-time monitoring; output assists clinical decision-making regarding fluid management and abdominal pressure status; benefits include automated, continuous monitoring of critical physiological parameters.

Clinical Evidence

Bench testing only. Testing included biocompatibility (ISO 10993-1), performance per ASTM F623-99, MR compatibility (ASTM F2052, F2213, F2182, F2119), and electrical safety/EMC (IEC 60601-1, IEC 60601-1-2). No clinical data provided.

Technological Characteristics

16 French, 4-lumen silicone urinary catheter; single-use; sterile. Sensing: thermistor for temperature, closed air column with internal pressure transducer for intra-abdominal pressure. Connectivity: monitor-based display. Standards: ASTM F623-99 (Foley performance), ISO 10993 (biocompatibility), IEC 60601-1 (electrical safety). MR conditional.

Indications for Use

Indicated for patients requiring urinary drainage, collection, and monitoring of urine output, core body temperature, and intra-abdominal pressure. Used as an aid in diagnosing intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS). Short-term use (<30 days).

#### IV. Device Description

The Accuryn Monitoring System consists of the three components, the Accuryn Sensing Urinary Catheter, Accuryn Urine Collection Set, and the Accuryn Monitor.

The Accuryn Sensing Urinary Catheter is a single use, sterile, MR conditional, disposable 16 French, twoway silicone urinary bladder catheter with two opposing drainage eyes and 4 lumens.

The first lumen of the Urinary Catheter is for urine drainage and is packaged pre-connected to the Accuryn Urine Collection Set. The Accuryn Urine Collection Set function with the Accuryn Monitor to measure and display urine output and is considered a 510(k) exempt device per 21 CFR 876.1800 (urine flow or volume measuring system, product code EXY).

The second lumen is for the 5cc retention balloon, which serves to keep the catheter in place. Inflation of the retention balloon is provided by connecting a barrel tip syringe filled with sterile water to the catheter by means of a two-way valve. Sterile water is conveyed through the retention balloon lumen to inflate the retention balloon; water is contained within the balloon to maintain retention; the water is removed by reopening the valve to deflate the balloon prior to removing the catheter from the bladder.

The third lumen contains a thermistor wire for monitoring a patient's core body temperature in degrees Fahrenheit and degrees Celsius when connected to the Accuryn Monitor.

The fourth lumen consists of a closed air column that connects to a pressure transducer inside the Accuryn Monitor. Intra-abdominal pressure is measured via this lumen and displayed on the Monitor screen.

#### V. Indications for Use

The Accuryn Monitoring System is intended for use in the drainage and/or collection of urine, and in the monitoring of urine output and core body temperature, in degrees Fahrenheit and degrees Celsius. The Accuryn Monitoring System is also intended for use in the monitoring of intra-abdominal pressure. The measured pressures can be used as an aid in the diagnosis of intra-abdominal hypertension (IAH) and the associated clinical syndrome of abdominal compartment syndrome (ACS). The Accuryn Sensing Urinary Catheter is a single use device intended for short-term use (less than 30 days).

#### VI. Substantial Equivalence

The Accuryn Monitoring System utilizes substantially equivalent performance attributes as the predicate devices. Similarities to the predicate device include the following:

- Provided Sterile
- Single Use
- Materials used
- Performance standard ASTM F623-99(2006)
- Urinary catheter properties (shaft color, shaft diameter, retention balloon size)
- Temperature measurement functionality
- . Pressure measurement functionality

Differences in technological characteristics between the Accuryn Monitoring System and the predicate devices do not raise different questions of safety and effectiveness. Accepted scientific methods exist for assessing the effect of these different characteristics, such as bench and biocompatibility testing.

#### VII. Performance Data

Biocompatibility testing was conducted in accordance with ISO 10993-1:2009/(R)2013, Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process and FDA Draft Guidance, Use of International Standard ISO 10993 "Biological Evaluation of Medical Devices Part 1: Evaluation of Testing." Performance bench testing was performed per ASTM F623-99 (2006), Standard Performance Specification for Foley Catheter and Coefficient of Friction testing. MR compatibility testing was conducted in accordance with ASTM F2052-14, Standard Test Method for Measurement of Magnetically Induced Displacement Force on Medical Devices in the Magnetic Resonance Environment, ASTM F2213-06 (R2011), Standard Test Method for Measurement of Magnetically Induced Torque on Medical Devices in the Magnetic Resonance Environment, ASTM F2182-11a, Standard Test Method for Measurement of Radio Frequency Induced Heating Near Passive Implants During Magnetic Resonance Imaging, and ASTM F2119-07 (R2013), Standard Test Method for Evaluation of MR Image Artifacts from Passive Implants. Software-related documentation provided in accordance with FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (2005) for Moderate Level of Concern device. The Accuryn Monitoring System meets the requirements of basic safety and essential performance as defined by the IEC 60601-1 2005 300 Edition, Medical electrical equipment - Part 1: General requirements for basic safety and essential performance and complies with IEC 60601-1-2 2007, Medical Electrical Equipment – Part 1-2: General requirements for basic safety and essential performance – Collateral standard: Electromagnetic compatibility – Requirements and tests.

## VIII. Conclusions

Results from the bench tests for design verification and validation have proven acceptable performance on all tests to indicate that the device is suitable for its intended use and is as safe and effective as the predicate devices to support a determination of substantial equivalence.
