No
The 510(k) summary describes a diagnostic mapping catheter for sensing electrical potentials and pacing in the heart. There is no mention of AI, ML, image processing, or any computational analysis of the collected data that would suggest the use of these technologies. The performance studies focus on biocompatibility, reliability, and animal studies evaluating maneuverability and signal quality, not algorithmic performance.

No
The document states that the device is a "diagnostic medical device" and is "contraindicated for ablation," which is a therapeutic procedure. Its primary functions are "electrogram recording and pacing during diagnostic electrophysiology studies."

Yes
The "Intended Use / Indications for Use" and "Device Description" sections explicitly state that the Pathfinder® 3mm Mapping Catheter is a "diagnostic medical device." It is designed for "sensing of electrical potentials in the heart" and "electrogram recording" for "diagnostic electrophysiology studies."

No

The device description clearly details a physical catheter with electrodes, a specific diameter, and usable lengths, indicating it is a hardware device, not software-only.

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

Here's why:

  • Intended Use: The intended use is for "localized unipolar or bipolar sensing of electrical potentials in the heart" and "pacing during diagnostic electrophysiology studies." This involves directly interacting with the patient's body to record electrical signals and deliver electrical pulses.
  • Device Description: The device is a catheter designed to be inserted into the heart.
  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, tissue) to detect diseases, conditions, or infections. This device does not perform tests on samples outside the body.

The Cardima Pathfinder® 3mm Mapping Catheter is a diagnostic medical device that is used in vivo (within the living body).

Device Description

The Cardima Pathfinder® 3mm Mapping Catheter is a diagnostic medical device designed to provide localized unipolar or bipolar sensing of electrical potentials in the heart. The catheter is available with 4 or 8, 3mm long electrodes spaced 2mm apart providing for a total electrode recording length of 4cm.

The outer surface is treated with a hydrophilic coating to enhance lubriciousness.

The Pathfinder 3mm Mapping Catheter is packaged individually in a polyethylene protective coil. Each coil is in turn placed in a clear, blue tinted tray and a translucent-white Tyvek lid that is heat sealed to the outside of the tray . This sealed tray is placed within a standard Tyvek/polyester-polyethylene pouch which is also heat sealed. All product is sterilized using gamma radiation.

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

Safety and effectiveness were evaluated through biocompatibility testing and animal studies. Biocompatibility testing was conducted on final sterilized Pathfinder product per ISO 10993-1 and shown to be acceptable for all categories. Reliability testing was conducted on sterilized product per "Electrode Recording Catheter Preliminary Guidance, March 1995". The tests were used to assess the mechanical and electrical properties of both the catheter and the connector cable and found to be acceptable for use.

Animal studies were conducted to evaluate the maneuverability of the Pathfinder 3 mm catheter positioned in the coronary sinus, right atrium and right ventricle. The catheter could be positioned into the coronary sinus, right atrium and right ventricle without significant difficulty, and signals were of good quality and adequate for clinical applications. Pacing was easily achieved at clinically-relevant thresholds. During one study, coronary sinus thrombosis occurred in one animal, believed to result from manipulation of the guiding catheter. Otherwise, this procedure was found to be safe without injury to the animals.

(a)
Identification. An electrode recording catheter or an electrode recording probe is a device used to detect an intracardiac electrocardiogram, or to detect cardiac output or left-to-right heart shunts. The device may be unipolar or multipolar for electrocardiogram detection, or may be a platinum-tipped catheter which senses the presence of a special indicator for cardiac output or left-to-right heart shunt determinations.(b)
