Intended Use
The Cardima Tracer Over-the-Wire Mapping Microcatheter is a diagnostic medical device designed to provide localized unipolar or bipolar sensing of electrical potentials as measured from within the venous system of the heart. The Tracer catheter can also be utilized for temporary epicardial pacing during the mapping procedure. The catheter is designed to accommodate a 0.010" guide wire and is available in five configurations with either 4, 8, or 16 electrodes. Both the 4 and 8 electrode catheters come with either regular spaced electrodes of 5mm or electrode pair spacing of 2-5-2 mm. The 16 electrode catheter is available only with 2-5-2mm pair spacing. The outer diameter of the catheter is 3.2F - 3.3F and will be available with working lengths of 145cm. The outer surface is treated with a hydrophilic coating to enhance lubriciousness. The Tracer is not indicated for ablation.
Device Story
Diagnostic mapping microcatheter; over-the-wire design (0.010" guide wire); 4, 8, or 16 electrodes. Inputs: cardiac electrical potentials from coronary sinus/venous system. Operation: physician-guided placement in coronary veins; provides unipolar/bipolar sensing; enables temporary epicardial pacing. Output: electrical signals displayed for clinical interpretation. Benefit: facilitates cardiac mapping and pacing procedures. Not indicated for ablation.
Clinical Evidence
Animal studies evaluated maneuverability, signal quality, and pacing capability in coronary sinus/veins. Results: successful positioning; good signal quality; effective ventricular pacing (threshold 0.1-1.9 mA @ 2.0 msec). Safety: no rupture, thrombosis, or pericardial effusion; minor subepicardial hemorrhage deemed clinically insignificant.
Technological Characteristics
Hydrophilic-coated catheter; 3.2F-3.3F diameter; 145cm length. Electrodes: 4, 8, or 16 configurations. Biocompatibility per ISO 10993-1. Reliability testing per 'Electrode Recording Catheter Preliminary Guidance, March 1995'. Gamma sterilization.
Indications for Use
Indicated for cardiac mapping in patients requiring temporary recording of epicardial electrical signals from the coronary sinus and temporary pacing during mapping procedures.
Regulatory Classification
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.

# Trade Name:
Cardima Tracer Over-the-Wire Mapping Microcatheter
## Manufacturer:
Cardima. Inc. 47266 Benicia Street Fremont, CA 94538-7330 Contact: Shelley Trimm Establishment Registration Number: 9007594
## Classification Name:
Electrode Recording Catheter (21 CFR 870.1220)
## Device Classification:
Class II (21 CFR 870.1220) Panel: Circulatory System Devices Panel, DCRND
## Intended Use and Product Description:
The Cardima Tracer Over-the-Wire Mapping Microcatheter is a diagnostic medical device designed to provide localized unipolar or bipolar sensing of electrical potentials as measured from within the venous system of the heart. The Tracer catheter can also be utilized for temporary epicardial pacing during the mapping procedure. The catheter is designed to accommodate a 0.010" guide wire and is available in five configurations with either 4, 8, or 16 electrodes. Both the 4 and 8 electrode catheters come with either regular spaced electrodes of 5mm or electrode pair spacing of 2-5-2 mm. The 16 electrode catheter is available only with 2-5-2mm pair spacing. The outer diameter of the catheter is 3.2F - 3.3F and will be available with working lengths of 145cm. The outer surface is treated with a hydrophilic coating to enhance lubriciousness. The Tracer is not indicated for ablation.
## Sterilization, Packaging and Pyrogenicity:
The Tracer is packaged individually as a coil in a clear, blue tinted polyethylene teraphthlate (PETG) tray which is heat-sealed with a translucent-white Tyvek lid. This sealed tray is placed within a standard Tyvek/polyester-polyethylene pouch which is also heat sealed. Both Tracer and Pathfinder utilize the identical packaging materials and process for gamma sterilization. The design modification to Tracer does not introduce any new or unique challenges to the current validate sterlization process. Given these considerations re-validating the sterilization process used for Tracer was deemed unnecessary.
## Substantial Equivalence:
The Tracer Over-the-Wire Mapping Catheter is a modified version of Cardima 2.5F Pathfinder electrode recording catheter (cleared K955802). Establishment of equivalence was based on similarities of labeling, design, materials, and physical characteristics as evaluated by physical bench testing, biocompatibility and animal studies. The primary design modification involves use of an over-the-wire feature and a larger outer diameter. The additional intended for use claim: "can be utilized for temporary pacing", was supported by the animal studies.
## Summary of Safety and Effectiveness:
Safety and effectiveness were evaluated through biocompatibility testing and animal studies. The Tracer and the Pathfinder utilize the same materials requiring biocompatibility testing. Therefore, the biocompatibility testing conducted on final sterilized Pathfinder product per ISO 10993-1, which were shown to be acceptable for all categories, was deemed applicable to the Tracer. Reliability testing was conducted on sterilized Tracer product per "Electrode Recording Catheter Preliminary Guidance, March 1995". The tests were used to assess the mechanical and electrical properties of the catheter and found to be acceptable for use.
{1}------------------------------------------------
Animal studies were conducted to evaluate the maneuverability and signal quality of the Tracer positioned in the coronary sinus and coronary veins. The Tracer catheter was also evaluated for pacing. The catheter could be positioned into the coronary sinus and distal coronary veins without difficulty. Signals were of good quality and adequate for clinical applications. Ventricular pacing from different pairs of electrodes on the Tracer were conducted on twelve occasions (threshold 0.1 - 1.9 mA @ a pulse width of 2.0 msec.). Coronary sinus angiography post-procedure showed normal venous anatomy without rupture or thrombosis. Effusion of dye outside the coronary venous system was not evident, nor was pericardial effusion found on gross examination of the heart. In two cases small patches of subepicardial hemorrhage were found on post-mortem inspection, and are believed to be clinically insignificant.
