INDIGO Aspiration Catheters and Separators: As part of the INDIGO Aspiration System, the INDIGO Aspiration Catheters and Separators are indicated for the removal of fresh, soft emboli and thrombi from vessels of the peripheral and venous systems.

INDIGO Aspiration Tubing: As part of the INDIGO Aspiration System, the INDIGO Sterile Aspiration Tubing is indicated to connect the INDIGO Aspiration Catheters to the Penumbra Aspiration Pump.

Penumbra Aspiration Pump: The Penumbra Aspiration Pump is indicated as a vacuum source for Penumbra Aspiration Systems.

The Indigo Aspiration System is intended for the removal of fresh, soft emboli and thrombi from vessels of the peripheral arterial and venous systems. The Aspiration Catheter, Separator and Aspiration Tubing are available in multiple configurations. The devices are provided sterile, non-pyrogenic, and intended for single use only. Intended users for this device are physicians who have received appropriate training in interventional techniques.

The INDIGO® Aspiration System is comprised of several devices:

• INDIGO Aspiration Catheter .
• Penumbra Aspiration Pump .
• INDIGO Aspiration Pump Canister ●
• INDIGO Aspiration Tubing ●
• INDIGO Separator™ ●

The INDIGO Aspiration System is designed to remove thrombus from the vasculature using mechanical aspiration. The INDIGO Aspiration Catheter targets aspiration from the pump directly to the thrombus. The INDIGO Separator may be used to clear the lumen of the INDIGO Aspiration Catheter should it become blocked with thrombus. The INDIGO Aspiration Catheter is introduced through a guide catheter or vascular sheath into the peripheral vasculature and guided over a guidewire to the site of the primary occlusion. The INDIGO Aspiration Catheter is used with the Penumbra Aspiration Pump to aspirate thrombus from an occluded vessel. As needed, an INDIGO Separator may be deployed from the INDIGO Aspiration Catheter to assist with thrombus removal. The INDIGO Separator is advanced and retracted through the INDIGO Aspiration Catheter at the proximal margin of the primary occlusion to facilitate clearing of the thrombus from the INDIGO Aspiration Catheter tip. The devices are visible under fluoroscopy. For the aspiration source. the INDIGO Aspiration Catheter is used in conjunction with the Penumbra Aspiration Pump, which is connected using the INDIGO Aspiration Tubing and the INDIGO Aspiration Pump Canister. The INDIGO Aspiration Catheter may be provided with a steam shaping mandrel, rotating hemostasis valve, and introducer. The INDIGO Separator may be provided with an introducer and torque device.

The provided text describes the submission of a 510(k) premarket notification for the "Indigo System Aspiration Catheter 12, Indigo Aspiration System Separator 12." This specific document is a summary of non-clinical data and does not contain information about a study based on the performance of an AI/ML powered medical device.

Therefore, I cannot answer questions 1 through 9. The information provided in the document focuses on the physical and material properties of a medical device (a catheter and separator for aspiration), its biocompatibility, shelf life, sterilization, and packaging, rather than the performance of an AI/ML algorithm.

The "Acceptance Criteria" table in this document refers to engineering specifications (e.g., maximum friction force, minimum burst pressure, particle limits) for the physical device, not performance metrics for an AI/ML model.

The Phoenix Atherectomy System is intended for use in atherectomy of the peripheral vasculature. The system is not intended for use in the coronary, carotid, iliac, pulmonary, or renal vasculature.

Phoenix Atherectomy Plus System:

When used with the Phoenix Aspiration Pump as the vacuum source, the Phoenix 2.4mm Deflecting Atherectomy System is indicated for the removal of thrombus from vessels of the peripheral arterial vasculature.

The Phoenix 2.4mm Atherectomy Plus System comprises the currently cleared Phoenix 2.4mm Deflecting Atherectomy System (K172386) and a new Phoenix Aspiration Pump. which when used in conjunction with each other are designed for removal of thrombus from vessels of the peripheral arterial vasculature.

The Phoenix 2.4mm Deflecting Atherectomy System and the Phoenix Aspiration Pump are sterile, single-use devices that are sterilized using Ethylene Oxide (EO). The Phoenix 2.4mm Deflecting Atherectomy System comprises the Phoenix 2.4mm Deflecting Atherectomy Catheter and the Phoenix Atherectomy Handle with Wire Support Clip.

The Phoenix Catheter is an over-the-wire (OTW), multi-lumen Catheter with a cutter at the distal tip that continuously captures and clears debulked (excised) material proximally through the Catheter and Handle into a collection reservoir that resides outside the patient. For use, the Phoenix Catheter is inserted into the Phoenix Handle incorporates a self-contained battery-powered motor designed to drive and rotate the cutter of the Phoenix Atherectorny Catheter at its specified rotational speed, and is activated by an ON/OFF slider switch on the top of the Handle. A Wire Support Clip is used to hold a guidewire in a fixed position relative to the Phoenix Handle and prevent guidewire rotation during the procedure. The Catheter, Handle, and Wire Support Clip are packaged as sterile, single-use components of the Phoenix Atherectomy System. The Phoenix Catheter is compatible with commercially available 0.014" exchange length (260 cm or greater) guidewires.

For the purpose of this 510(k), the design of the Phoenix 2.4mm Deflecting Atherectomy System remains unchanged.

The Phoenix Aspiration Pump connects to the disposal outlet of the Phoenix Catheter via the pump's aspiration tubing. The exit end of the aspiration tubing is connected to a waste disposal bag to collect aspirated material. A 60 ml syringe is provided as part of the Aspiration Pump Assembly to assist in priming the pump aspiration tubing and purging the aspiration system of air. The Aspiration Pump is battery-operated and is operated by an ON/OFF switch. It serves as a vacuum source for the Aspiration System for aspirating the thrombus from the target vessel out of the Phoenix Catheter via the pump aspiration tubing and into the disposal bag. The Aspiration Pump is non-patient contacting.

The provided text is a 510(k) summary for the Phoenix 2.4mm Atherectomy Plus System. It describes the device, its intended use, and a comparison to predicate and reference devices, as well as a summary of testing performed to demonstrate substantial equivalence. However, it does not contain the specific information requested about acceptance criteria and a study that proves the device meets those criteria in the context of an AI/algorithm-driven device performance study.

The document describes the device as a mechanical atherectomy system with an aspiration pump for removing thrombus, which is a physical device, not an AI or algorithm. The "Testing Summary" section lists various engineering and preclinical tests (e.g., visual inspection, vacuum and leak test, flow rate test, system simulated use test, preclinical animal testing), which are typical for medical devices of this nature. There is no mention of an algorithm, AI, or any data-driven performance study comparing human readers with and without AI assistance, or standalone algorithm performance, or ground truth establishment based on expert consensus for image analysis.

Therefore, I cannot provide the requested information from the given text. The text does not detail an AI/algorithm-driven study with acceptance criteria.
