The Millipede 070 Aspiration Catheter, used with the Perfuze Aspiration Tube Set and an aspiration pump, is indicated for revascularization in patients with acute ischemic stroke, which constitutes a therapeutic intervention.

No.
The devices (catheter and tube set) are described as tools for facilitating insertion, guidance, and revascularization (removing occlusions), not for identifying or diagnosing a medical condition.

No

The device description clearly details physical hardware components including catheters, valves, and tubing, and the performance studies focus on mechanical and visual properties, not software performance.

Based on the provided information, no, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use of these devices is to facilitate the insertion and guidance of other catheters into blood vessels (Millipede 088 Access Catheter) and for the revascularization of patients with acute ischemic stroke by removing blood clots (Millipede 070 Aspiration Catheter and Perfuze Aspiration Tube Set). These are therapeutic and interventional procedures, not diagnostic tests performed on samples taken from the body.
  • Device Description: The descriptions detail the physical components and function of catheters and tubing used for accessing and manipulating within the vascular system. There is no mention of reagents, assays, or analysis of biological samples.
  • Performance Studies: The performance studies described are non-clinical bench tests evaluating mechanical integrity and visual characteristics, not diagnostic accuracy metrics like sensitivity, specificity, or AUC.
  • Input Imaging Modality: Fluoroscopy is used for visualization during the procedure, which is common for interventional devices, not for analyzing biological samples.

IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for the diagnosis, monitoring, or treatment of a disease or condition. The devices described here are tools used within the body to perform a therapeutic intervention.

Biocompatibility

The subject Millipede 070 Aspiration Catheter and Millipede 088 Access Catheter include a change to the color additives used in the proximal shaft compared to the predicate devices. To ensure these new color additives were assessed, relevant biocompatibility endpoints were addressed through biocompatibility testing in accordance with ISO 10993-1, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing within a Risk Management Process". The table below summarizes the biocompatibility testing completed.

Biocompatibility testing of the Millipede 070 Aspiration Catheter (listed below), which utilizes the same color additives, was used to also support the biocompatibility of the Millipede 088 Access Catheter.
