Intended Use
The PleuraFlow System is indicated for use during cardiothoracic surgical procedures and chest trauma. Its Active Clearance Technology® proactively removes clots formed inside the chest tube to prevent or minimize chest tube occlusion with clot. A patent chest tube enables evacuation of blood and fluid from the operative site after closure of the surgical wound and reduces retained blood. The product is indicated for adult and pediatric patients including infant, preadolescent and adolescent patients under clinical settings.
Device Description
The PleuraFlow System is comprised of a silicone Chest Tube and a Clearance Apparatus. Currently the PleuraFlow Chest Tube is available in four (4) models with standard sizes (20FR, 24FR, 28FR and 32FR). The Chest Tubes of currently marketed and above-references PleuraFlow System models include six (6) eyelets distributed along an Effective Drainage Length of 4 inches (10.2 cm). The Effective Drainage Length is defined as the length of the Chest Tube having eyelets for the influx of fluid. The current Chest Tube models are available with a Cut Length of 19 inches (48.3 cm) with graduated measurements in centimeters from the distal eyelet. Each Chest Tube has a barium stripe to facilitate visualization. The Chest Tube is connected to a Clearance Apparatus, which is connected to the tubing from the drainage canister. The new PleuraFlow System model is similar to the current models except for the Chest Tube, which has four eyelets instead of 6 eyelets. The short Effective Drainage length is only available with a 20FR Chest Tube identifies as: Short Effective Drainage Length (SEDL). This model has four (4) eyelets distributed along an Effective Drainage Length of 2 inches (5.1 cm). This Chest Tube model has a Cut Length of 19 inches (48.3 cm) with graduated measurements in centimeters from the distal eyelet and a barium stripe to facilitate visualization, as all of the currently marketed Chest Tubes have. Same as the marketed models, the 20FR SEDL Chest Tube is connected to a Clearance Apparatus, which is connected to the tubing from the drainage canister. The Clearance Apparatus that is part of the PleuraFlow System with 20FR SEDL Chest Tube is same as the predicate. It consists of a Guide Tube and a PTFE-coated Clearance Wire with a Loop set on its distal end, bent at a 105-degree angle. The Clearance Apparatus is advanced into the PleuraFlow Chest Tube using a magnetic Shuttle. When indicated, the Clearance Wire and Loop is advanced and retracted within the PleuraFlow Chest Tube to proactively prevent or break up and clear any tube obstructions or clogging to keep the tube open. The PleuraFlow System with 20FR Short Effective Drainage Length (SEDL) Chest Tube can be used when the surgeon determines that a chest tube with a shorter length of drainage holes, 2" (5.1 cm) is needed. This includes patients having smaller dimension chests (length of torso) that cannot accommodate Chest Tubes with longer EDLs.
More Information

No
The device description and performance studies focus on mechanical components and established testing methods, with no mention of AI or ML.

Yes.

Explanation: The device is described as being "indicated for use during cardiothoracic surgical procedures and chest trauma" and "proactively removes clots formed inside the chest tube to prevent or minimize chest tube occlusion with clot," which directly relates to the treatment or mitigation of a condition.

No

The device description indicates that the PleuraFlow System is used to proactively remove clots and evacuate blood and fluid from the operative site after surgical procedures and chest trauma. Its function is therapeutic (preventing or clearing occlusion), not diagnostic (identifying a medical condition).

No

The device description explicitly details physical components including a silicone Chest Tube, a Clearance Apparatus, a Guide Tube, a PTFE-coated Clearance Wire, and a magnetic Shuttle. These are all hardware components, not software.

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

Here's why:

  • Intended Use: The intended use is to proactively remove clots from chest tubes during and after cardiothoracic surgery and chest trauma. This is a therapeutic and drainage function performed directly on the patient's body, not an analysis of samples taken from the body.
  • Device Description: The device consists of a chest tube and a clearance apparatus. These are physical tools used for drainage and clearing blockages within the chest tube, not for analyzing biological samples.
  • Lack of IVD Characteristics: The description does not mention any components or functions related to:
    • Analyzing biological samples (blood, fluid, tissue, etc.)
    • Providing diagnostic information based on sample analysis
    • Reagents, calibrators, or controls typically associated with IVD tests

The device's function is to maintain the patency of a chest tube for drainage, which is a direct medical intervention, not a diagnostic test performed on a sample.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

  • Performance Data: The safety and effectiveness of the PleuraFlow System has been previously demonstrated through design validation and verification that were cleared under 510(k) premarket notification K093565 and K150042. The biocompatibility evaluation for the PleuraFlow System was conducted under predicate 510(k) K093565, in accordance with the FDA Blue Book Memorandum #G95-1 and International Standard ISO 10993-1. Mechanical testing was performed to establish substantial equivalence to the predicate 510(k) K093565. Testing was performed in accordance with BS EN 1617:1997 and BS EN 1618:1997. These included flow rate and tensile strength testing.

Predicate Device: Predicate device is the PleuraFlow System (K150042) by ClearFlow, Inc.

Device Description: The PleuraFlow System is comprised of a silicone Chest Tube and a Clearance Apparatus. Currently the PleuraFlow Chest Tube is available in four (4) models with standard sizes (20FR, 24FR, 28FR and 32FR). The Chest Tubes of currently marketed and above-references PleuraFlow System models include six (6) eyelets distributed along an Effective Drainage Length of 4 inches (10.2 cm).

model has four (4) eyelets distributed along an Effective Drainage Length of 2 inches (5.1 cm). This Chest Tube model has a Cut Length of 19 inches (48.3 cm) with graduated measurements in centimeters from the distal eyelet and a barium stripe to facilitate visualization, as all of the currently marketed Chest Tubes have. Same as the marketed models, the 20FR SEDL Chest Tube is connected to a Clearance Apparatus, which is connected to the tubing from the drainage canister. The Clearance Apparatus that is part of the PleuraFlow System with 20FR SEDL Chest Tube is same as the predicate. It consists of a Guide Tube and a PTFE-coated Clearance Wire with a Loop set on its distal end, bent at a 105-degree angle. The Clearance Apparatus is advanced into the PleuraFlow Chest Tube using a magnetic Shuttle. When indicated, the Clearance Wire and Loop is advanced and retracted within the PleuraFlow Chest Tube to proactively prevent or break up and clear any tube obstructions or clogging to keep the tube open.

The PleuraFlow System with 20FR Short Effective Drainage Length (SEDL) Chest Tube can be used when the surgeon determines that a chest tube with a shorter length of drainage holes, 2" (5.1 cm) is needed. This includes patients having smaller dimension chests (length of torso) that cannot accommodate Chest Tubes with longer EDLs.
