The device description and performance studies focus on the mechanical and fluid dynamics of the delivery lines, with no mention of AI or ML.
No.
The device, Micro Prime Delivery Lines, is used to convey blood and cardioplegia in an extracorporeal circuit, specifically for pediatric cardiopulmonary bypass. While it plays a crucial role in patient management by minimizing prime volume and aiding in the circulatory process, it is a component of a larger system that performs therapy (cardiopulmonary bypass) rather than being a therapeutic device itself that directly treats a disease or condition. It facilitates therapy by optimizing blood prime volume, but it doesn't apply therapeutic energy, substances, or actions.
No.
The device is described as delivery lines for conveying arterial blood and cardioplegia, and its function involves minimizing prime volume and managing pressure, not diagnosing medical conditions.
No
The device description clearly describes a physical medical device consisting of a dual lumen extrusion (tubing) used to convey blood and saline, with functional testing related to material properties, blood trauma, and pressure drop. There is no mention of software as the primary or sole component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "convey arterial blood and cardioplegia with minimal prime volume in the extracorporeal circuit." This describes a device used during a medical procedure (cardiopulmonary bypass) to handle and transport blood and fluids within the body's circulatory system.
- Device Description: The description details the physical structure and mechanism of the tubing for managing blood flow and prime volume. It focuses on the mechanical function of the device in a surgical setting.
- Lack of IVD Characteristics: An IVD device is used to examine specimens from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not perform any analysis or testing of the blood or fluids; it simply transports them.
- Performance Studies: The performance studies focus on the physical and functional aspects of the tubing (blood trauma, pressure drop, sterilization, aging, package integrity), not on the analytical performance of a diagnostic test.
Therefore, the Micro Prime Delivery Lines are a medical device used in a surgical procedure, not an in vitro diagnostic device.

Device Description
Micro Prime Delivery Lines minimize the blood prime volume DESCRIPTION of the DEVICE: in the extracorporeal circuit. For pediatric cardiopulmonary bypass, where excessive priming volume can increase surgical risk, Micro Prime delivery lines offer a distinct advantage. Micro Prime Delivery Lines consist of a dual lumen extrusion: a round "blood" lumen used to convey blood to/from the patient, and a crescent shaped "occlusion" lumen which surrounds the blood lumen, and is used to purge excess prime volume from the blood lumen.
In use, both lumens are initially primed with saline. Once the tubing has been primed, the occlusion lumen is pressurized with additional saline, collapsing the blood lumen and purging excess priming fluid from the blood lumen. Releasing the pressure from the occlusion lumen causes the blood lumen to re-open to its normal shape. In this manner, Micro Prime Delivery Lines regligible blood volume to prime as compared to conventional delivery lines.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
InnovX Medical, Inc. conducted functional testing for Micro Prime delivery line samples, which had been ethylene oxide sterilized twice, aged for the equivalent of one year, and ship tested at cold and at warm temperatures. Units passed functional requirements.
Biocompatibility testing and reference to Device Master File for silicone rubber extrusion demonstrate suitability of the materials.
The potential for blood trauma was assessed over a 6-hour period using bovine blood in five 3/16" ID Micro Prime delivery tubes and five 3/16" ID conventional extracorporeal delivery tubes, flowing through a simulated extracorporeal circuit. Blood trauma was assessed by measuring plasma hemoglobin, white blood cell count, and platelet count at half hour intervals over the duration of the test. Statistical analysis of the data using hypothesis test of means indicates that blood trauma associated with Micro Prime Delivery Tubes is comparable to blood trauma for conventional delivery tubes.
Pressure drop data was simultaneously monitored across the ten samples in the blood trauma evaluation to assess whether Micro Prime Delivery Tubes had a negative impact on pressure in the extracorporeal circuit. Analysis of this data indicates that pressure drop in Micro Prime Delivery Tubes is nominally lower than conventional delivery tubes.
Comparison of sterile/aged, non-sterile-non aged product revealed there is no statistically significant difference between groups. Package Integrity Ship Testing for one year aging showed no changes to the specimens and that the package held integrity under the conditions tested. Design Verification was conducted to assure product met criteria. Positive pressure experial and cardioplegia) met all acceptance criteria and are qualified for 2c ETO and one-year shelf life. Due to the results from venous drainage experiments, the Micro Prime Delivery Line is contraindicated for venous drainage.
Testing confirmed that the design did not introduce any new safety concerns and performed equivalent to or better than conventional PVC cardiopulmonary bypass lines.
