- (1) Slight modification to the predicate Compass CT Port circuit board to accommodate an added secondary Bluetooth radio board that allows for wireless communication with the new Compass MAP. All modifications are internal to the Compass Cast, so that the external plastic housing and all other physical components of the device remain identical to the predicate Compass CT Port.
- (2) Development of new Compass Monitor Accessory Plug (MAP), which is a reusable, non-sterile component that can be plugged into a compatible monitor and paired to the Compass Cast to then allow for complementary display of all pressure information on a separate monitor.

The Compass CT and Compass CT Port are disposable, point-of-use pressure measurement and monitoring devices that incorporate a pressure transducer and an integrated pre-programmed diagnostic computer with liquid crystal display (LCD). The devices have a distal male luer fitting to connect to a needle or catheter, and a proximal female luer fitting that can be connected to accessory devices (e.g. syringes, caps, or infusion tubing). The devices measure the pressure via an embedded pressure sensor, internally convert changes in pressure into electrical currents, and then display the resulting pressure via the integrated LCD. The Compass CT Port has an additional, sealed proximal port through which commercially available guidewires can be inserted during pressure measurement.

{4}------------------------------------------------

## Description:

The Compass CT Port device is being modified to add wireless Bluetooth capability to the point-of-use Compass Cast device, in order to allow for optional display of acquired pressure data and information to a separate display monitor. The modified product will consist of two components that are packaged separately, the compass Cast (Subject Device) and MAP (Monitor Accessory Plug - Accessory).

The Compass Cast (Subject Device) is a single-use, sterile pressure transducer that is physically identical to the predicate device Compass CT Port (510(k) K133624) with the exception of a slight modification to the main CT Port circuit board to accommodate the secondary Bluetooth radio board. All components and functionality of the main circuit board remain identical.

The MAP (Accessory) is a non-sterile, reusable monitor accessory plug that receives a digital pressure signal from the Compass Cast and converts the digital pressure signal to an analog output that is identical to the analog output of a traditional wired pressure transducer. There are two versions of the MAP device:

- 1) Wireless Pressure Receiver - GE Monitor (CWMG001-5)
- 2) Wireless Pressure Receiver Philips Monitor (CWMP001-5)

The MAP Accessory has not received prior 510(k) clearance.

### Indications for Use:

The Compass Cast and MAP disposable pressure transducer system with integrated digital display and wireless transmission capability is intended for direct measurement and monitoring of physiologic pressure, including during the infusion of fluids and therapeutic and diagnostic agents.

### Summary of Technological Characteristics between Subject and Predicate Device:

The Compass Cast and MAP system retain the same fundamental scientific technology as the predicate device. The intended use is identical as well as the operating principles at the point of use with the compass Cast – direct measurement of physiological pressure, including during the infusion of fluids and therapeutic and diagnostic agents.

ldentical to the predicate Compass CT Port, the Compass Cast remains a single-use, sterile pressure transducer that is physically identical to the Compass CT Port from 510(k) K133624 except for: (1) a secondary, internal circuit board that gives the modified device wireless (low energy Bluetooth) capability, and (2) a slightly thicker battery to provide increased capacity due to the added wireless transmission functionality. The Compass Cast device thus incorporates the exact physical elements (including a coin cell battery) contained in the predicate Compass CT Port except for some slight modifications to the main predicate Compass CT Port circuit board changes were necessary to accommodate the added secondary Bluetooth radio board, but all components and functionality of the main circuit board remain identical. The Compass Cast and MAP do not transmit any patient identifying data; they simply transmit pressure data that has no patient identifiers. The Bluetooth capability allows the pressure data to be freely viewable on the monitors in the patient room without the use of a wire connection. Lastly, while the Compass Cast uses a thicker coin cell battery compared to the predicate Compass CT Port (specifically, it uses a CR1632 instead of a CR1616) to account for the added wireless transmission functionality drawing more power from the battery, the nominal voltage of the two batteries remains identical (3V).

Following is a side by side comparison of the features of the subject and predicate device.

## Performance Data:

The results of performance testing demonstrate that the functionality, integrity, and safety and effectiveness of the Compass Cast and MAP System are sufficient for its intended use and support a determination of substantial equivalence.

#### Summary of Testing: Sterilization

The Compass Cast will be available only in sterile product will be sterilized using ethylene oxide. The sterilization method was validated and performed in accordance with ANSI/AAMI/ISO 11135-1:2014, Sterilization of health care products – Ethylene oxide - Requirement, validation and routine control of a sterilization process for medical devices. A sterility assurance level of 1 x 10 ° has been validated for this product.

The Compass MAP will be sold non-sterile, reusable, as an accessory to the Compass Cast.

## EO Residuals

Ethylene Oxide Residual testing was performed in accordance with ANSI/AAMI/ISO 10993-7:2008. Testing was performed (Centurion Protocol# 17205-16) on product code CLCK001 (Compass Vascular Access Lock) as this model was selected as a "worst case" representative for the Compass family of products. The Compass Vascular Access Lock is identical in physical construction to the Compass Cast with the exception of the electronics. A second circuit board is attached perpendicular to the main PCB in the Compass Cast to allow for wireless transmission capability. However, this additional component is contained within the device's housing and has no impact on sterility.

Three samples were processed through two routine (Cycle 20) sterilization cycles for a total of eight (8) hours exposure and subjected to 24 hours of forced heated aeration. The duration of contact for the Compass product is <8 hours. As a result, a simulated use extraction was performed at body temperature (37°C) for a duration of 8 hours. The proposed limits as defined in in ANSI/AAMI/ISO 10993-7:2008 are 4 mg/device for EO and 9 mg/device for EC.

### BET Testing

The Kinetic Chromogenic Test Method has been validated as the test method for determining the presence of bacterial endotoxins on the Compass family of devices. The Endotoxin limit applied to the Compass Products is 2.15 EU/Device (0.06 EU/ml). The selected endotoxin limit is based on the potential contact with Cerebrospinal Fluid in accordance with AAMI ANSI ST72:2011.

### Electromagnetic Compatibility/Electrical Safety

EMC and Wireless Communication Testing were performed on the Compass Cast and MAP system due to the modification to incorporate a low energy Bluetooth communication. A slight modification was made to the Compass CT Port circuit board to accommodate a secondary Bluetooth radio board that enables wireless communication. A thicker coin cell battery was also added to provide increased capacity. The Compass monitor accessory plug (MAP) was developed as a reusable, non-sterile component that can be plugged into a monitor and paired to the Compass Cast device to allow the pressure information to be viewed on a separate monitor. The Compass Cast and MAP were evaluated for electromagnetic compatibility and safety in accordance with IEC 60601-1-2:2007 and confirmed to be compliant. The results demonstrate that the Compass Cast and MAP, when transported, stored, installed, operated in normal use, and maintained according to the instructions of the manufacturer, cause no safety hazard which could reasonably be foreseen and which is not connected with its intended application, in normal condition and in single fault condition.
