The description focuses on the physical components and function of the device for pressure measurement and fluid collection, with no mention of AI or ML for data analysis or interpretation.
No
The device is described as aiding in the diagnosis of compartment syndrome by measuring pressure and collecting fluid, not in treating it.
Yes
The device is described as aiding in the diagnosis of compartment syndrome by measuring intracompartmental pressure and withdrawing fluid for analysis.
No
The device description clearly outlines physical components (Introducer, indwelling Catheter) and mentions use with other hardware (vacuum pump, infusion pump, pressure transducer, monitor).
Based on the provided information, the Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter System is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used outside of the body (in vitro).
- Device Function: The Twin Star system is designed to be inserted into the body (in vivo) to directly measure pressure within a muscle compartment and collect fluid from that compartment.
- Intended Use: While the collected fluid is intended for subsequent analysis (which would likely be an in vitro process), the device itself is the tool for collecting the sample and measuring pressure in vivo. The primary function of the device is not the diagnostic test itself, but rather providing the means to obtain information (pressure) and a sample for a separate diagnostic test.
Therefore, the Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter System is a medical device used for in vivo measurement and sample collection, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter System is intended for the immediate or continuous measurement of intracompartmental pressure or for the withdrawal of fluid for subsequent analysis. The measured pressures and the withdrawn fluid serve as an aid in the diagnosis of compartment syndrome.

Device Description
The Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter System Consists of two major componentic Oth Othpartners i.e., an Introducer and an indwelling Catheter. The Introducer provides an associety in the Monitoring and Fluid Collection Catheter. The placement of the mawelling intramuscular compartment pressure as well indwelling outhority a sample interstitial fluid for laboratory analysis. The indwelling as provide a means to campio into 24 hours. The Twin Star Compartment Pressure Oather is dong. But as a long Catheter System is designed to be used with currently Monitoring and Find equipment including a vacuum pump, infusion pump, pressure transducer and monitor.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Documentation has been provided which demonstrates that the Twin Star Compartment Pressure Monitoring and Fluid Collection Catheter System is substantially equivalent to other legally marketed devices such as the Stryker Intra-Compartment Pressure Monitor System. Comparisons were made demonstrating equivalent testing during animal and human clinical studies of the Twin Star Compartment Syndrome Pressure Monitoring and Fluid Collection Catheter System with the predicate system to measure intracompartment pressure in an animal model and a human clinical study.
