Intended Use
The Twin Star Compartment Pressure Monitoring and Fluid Collection Monitor (CMS Monitor) is intended for the measurement and monitoring of intracompartmental pressures and the withdrawal of fluid for subsequent analysis. The measured compartmental pressures can be used as an aid in the diagnosis of compartment syndrome. The CMS Monitor is intended to be used in conjunction with the Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter (CMS Catheter).
Device Description
The Twin Star Compartment Pressure Monitoring and Fluid Collection (CMS) Monitor displays and records pressure as measured by the Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter (CMS Catheter). The Twin Star CMS Catheter has been previously cleared by 510k notification. The multi-task CSM Monitor consists of a single housing unit that incorporates a vacuum pump, an infusion pump and a pressure monitor with visual display and user interface. The CMS Monitor provides the necessary functions required by the CMS Catheter. In addition to monitoring pressure, the CMS Monitor provides a very low volume fluid infusion to maintain the CMS Catheter's pressure lumen patency and a vacuum to the second lumen for fluid collection; both infusion and vacuum are required for the functional operation of the CMS Catheter.
More Information

No
The summary describes a device that measures and monitors pressure, infuses fluid, and applies vacuum. There is no mention of AI or ML in the intended use, device description, or performance studies.

No
The device is used to measure and monitor intracompartmental pressures to aid in the diagnosis of compartment syndrome, and to withdraw fluid for analysis. It does not directly treat a condition.

Yes

The device measures and monitors intracompartmental pressures, and these measurements can be used as an aid in the diagnosis of compartment syndrome.

No

The device description explicitly states the CMS Monitor consists of a "single housing unit that incorporates a vacuum pump, an infusion pump and a pressure monitor with visual display and user interface," indicating it is a hardware device with integrated software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The primary intended use is the measurement and monitoring of intracompartmental pressures and the withdrawal of fluid for subsequent analysis. While the fluid is collected for analysis, the device itself is not performing the diagnostic test on the fluid. It's a tool for collecting the sample and monitoring pressure in vivo.
  • Device Description: The device is described as a monitor with a vacuum pump, infusion pump, and pressure monitor. These are all functions related to in vivo measurement and fluid collection, not in vitro analysis of a sample.
  • Lack of IVD Characteristics: There is no mention of reagents, assays, or any other components typically associated with in vitro diagnostic testing. The device is interacting directly with the patient's body (intracompartmental).

The fluid collection aspect is for subsequent analysis, implying that the diagnostic testing on the collected fluid would be performed using a separate IVD device or laboratory method. The Twin Star CMS Monitor is a tool to aid in the diagnosis by providing pressure measurements and a fluid sample, but it is not performing the diagnostic test itself.

Description of the Device

The Twin Star Compartment Pressure Monitoring and Fluid Collection (CMS) Monitor displays and records pressure as measured by the Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter (CMS Catheter). The Twin Star CMS Catheter has been previously cleared by 510k notification. The multi-task CSM Monitor consists of a single housing unit that incorporates a vacuum pump, an infusion pump and a pressure monitor with visual display and user interface. The CMS Monitor provides the necessary functions required by the CMS Catheter. In addition to monitoring pressure, the CMS Monitor provides a very low volume fluid infusion to maintain the CMS Catheter's pressure lumen patency and a vacuum to the second lumen for fluid collection; both infusion and vacuum are required for the functional operation of the CMS Catheter.

Intended Use

The Twin Star Compartment Pressure Monitoring and Fluid Collection Monitor (CMS Monitor) is intended for the measurement and monitoring of intracompartmental pressures and the withdrawal of fluid for subsequent analysis. The measured compartmental pressures can be used as an aid in the diagnosis of compartment syndrome. The CMS Monitor is intended to be used in conjunction with the Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter (CMS Catheter),

Comparison of Technical Characteristics

The Twin Star CMS Monitor is equivalent to the Stryker Intracompartmental Syndrome Pressure Monitor System in that it has the same indications for use, the same target patient population and the same technical characteristics including a fluid filled pressure measuring catheter, a pressure monitor and a method of fluid infusion to maintain catheter patency. The only significant difference between the Twin Star CMS Monitor and the Stryker predicate is fluid removal using a vacuum. A predicate device that provides a vacuum for fluid removal is the Median Vacuum Pump. The Medela predicate removes fluid via a vacuum pump with similar indications for use, similar patient populations and similar technical characteristics. The administration of therapy is essentially the same between the Twin Star CMS Monitor and the predicates.

Performance Testing

Functional and performance testing was performed on the Twin Star CMS Monitor and its predicates. The results of measuring pressure, infusion and vacuum capabilities were compared. It was statistically proven that the performance of the Twin Star CMS Monitor was substantially equivalent to the performance of the predicate devices.

Conclusion/Substantial Equivalence

The Twin Star CMS Monitor has the same intended use compared to the Stryker predicate i.e., for monitoring intracompartment pressure as an aid in the diagnosis of compartment syndrome. Both the proposed monitors utilize utilize fluid infusion as a method of maintaining catheter patency to insure measurement accuracy. Performance testing has demonstrated equivalent results. The CMS Monitor provides a vacuum capability that the Stryker predicate does not. The CMS Monitor has a substantially equivalent intended use compared to the Medela predicate i.e., for vacuum pump removal of bodily fluids from wounds at the patient's bedside. Performance testing has demonstrated equivalent results.

Therefore, by claiming similar intended uses, similar patient populations and by demonstration of equal performance it is concluded that the CMS Monitor is substantially equivalent to the identified predicates.
