Device introduced via 8F introducer through right jugular approach. System comprises inner/outer shafts with 7 leads (3 ventricular, 4 atrial) in individual lumens. Passive fixation via flexible stainless steel leads (3 ventricular arms, 4 atrial arms). Transmits electrical signals between external pulse generator and heart; enables dual-chamber sensing and pacing. Used in clinical settings for patients requiring temporary pacing; operated by physicians. Benefits include synchronized pacing capability via single catheter. Performance verified through bench testing, GLP animal study, and prospective clinical study. ## Clinical Evidence Prospective, single-arm, single-site clinical study (n=30) evaluating temporary cardiac pacing. Primary efficacy endpoint: ventricular pacing threshold at 24 hours (mean 1.29V, met goal). Primary safety endpoint: incidence of serious procedural-related complications (met, zero serious device-related complications). Additional metrics: atrial pacing threshold, successful placement, sensing amplitude, pacing impedance, and incidence of lead dislodgement/fracture. GLP animal study (n=4 sheep) confirmed safety and tissue response over 7 days. ## Technological Characteristics 8F diameter catheter; 7 unipolar leads (3 ventricular, 4 atrial); passive fixation via flexible stainless steel leads. Compatible with 8F percutaneous introducer. Biocompatibility per ISO 10993-1. Single-use, non-pyrogenic. Electrical connectivity for external pulse generator/monitoring. Bench testing included dimensional, tensile, fatigue, continuity, hipot, torque, corrosion, and electrical safety/EMC. ## Regulatory Identification Temporary pacemaker electrode: A device consisting of flexible insulated electrical conductors with one end connected to an external pacemaker pulse generator and the other end applied to the heart. The device is used to transmit a pacing electrical stimulus from the pulse generator to the heart and/or to transmit the electrical signal of the heart to the pulse generator. Permanent pacemaker electrode: A device consisting of flexible insulated electrical conductors with one end connected to an implantable pacemaker pulse generator and the other end applied to the heart.

The device performance, local tissue response, gross necropsy, and histopathology were all evaluated. It was found that the Sync AV II demonstrated no safety concerns and performed as expected. ### 1.7.2 Clinical Study Overview A single-arm, single site, non-randomized, prospective clinical study was conducted to evaluate the substantial equivalence of the Sync AV II Temporary Pacing Catheter. A total of 30 subjects needing temporary cardiac pacing were enrolled in the study. The primary efficacy endpoint was ventricular pacing threshold at 24 hours post-implant. The average pacing threshold was 1.29V which met the predefined performance goal. The primary safety endpoint was the incidence of serious procedural-related complications defined per the clinical protocol. The primary safety endpoint was met with no serious device-related complications. Additional evaluations included: - Atrial Pacing Threshold at 24 hours post-implant (powered) - Successful placement of the device - Pacing threshold prior to lead removal - Sensing Amplitude and Pacing Impedance at 24 hours post-implant and prior to lead removal - Dual chamber sensing and pacing through lead removal - Incidence of lead dislodgement - Incidence of lead fracture ### 1.8 SUBSTANTIAL EQUIVALENCE Based on the same intended use, similar technological characteristics, and the summary of data submitted, the Sync AV II Temporary Pacing Catheter is found to be substantially equivalent to the predicate device. Safety and performance test data including bench testing, GLP animal study, electrical safety testing, and clinical study, demonstrated the device performed as intended without raising new and different questions of safety and effectiveness.
