Indications, Safety, and Warnings

Description

The Model 3830 lead is the safest1 and most studied2 lead for conduction system pacing (CSP).

  • Proven physiologic alternative to right ventricle (RV) pacing, reducing heart failure hospitalization (HFH) by 30% and all-cause mortality (ACM) by 34%3
  • Leader in LBBAP durability,1 with zero 3830 lead fractures observed in the public surveillance registry (PSR) study4 and predicted 10-year fracture rate of 0.02% (bench data)5
  • Fixed helix, lumenless design for increased implant stability6 and evidence from thousands of CSP implants4,7

Features

Proven reliability with robust lead design for CSP

The fixed helix design of 3830 reduces the number of moving parts within the lead architecture versus extendable-retractable helix leads, reducing fracture risk.6

  • 92.7% LBBA implant success rate across 6,000+ patients4
  • 2.5% LBBA adverse event rate7
  • Multiple meta-analyses show 3830 experiences lower rates of complications than stylet-delivered leads, particularly helix damage and lead dislodgements.10,11

Unmatched durability over time for LBBA implants

3830 is a compliant lead that experiences low bending stresses driven by its isodiametric cable-core design6

  • 0 CSP fractures at 36 months across 2,300+ patients4
  • 10-year simulated LBBAP bench data shows similar durability to traditional apical pacing, at 99.98% fracture-free rate.5
  • Leads were pre-conditioned to the ninety-fifth percentile stress condition ahead of durability test.
  • The 2024 Life-LBBAP study demonstrated 3830 LBBAP 99.9% fracture-free rate through 19.5 months average follow-up, in line with Medtronic bench reliability model.1

Proven reliability with robust lead design for CSP

The fixed helix design of 3830 reduces the number of moving parts within the lead architecture versus extendable-retractable helix leads, reducing fracture risk.6

  • Real-world data shows 92.7% LBBA implant success rate across 6,000+ patients.4
  • Literature review and meta-analysis show 2.5% LBBA adverse event rate.7
  • Multiple meta-analyses show 3830 experiences lower rates of complications than stylet-delivered leads, particularly helix damage and lead dislodgements.8,9

Unmatched durability over time for LBBA implants

3830 is a compliant lead that experiences low-bending stresses driven by its isodiametric cable-core design6

  • Real-world data shows 0 CSP fractures at 36 months across 2,300+ patients.4
  • 10-year simulated LBBAP bench data shows similar durability to traditional apical pacing, at 99.98% fracture-free rate.5
  • Leads were pre-conditioned to the ninety-fifth percentile stress condition ahead of durability test.
  • The 2024 Life-LBBAP study demonstrated 3830 LBBAP 99.9% fracture-free rate through 19.5 months average follow-up, in line with Medtronic bench reliability model.1

Leading precision at implant

A small outer diameter and central cable design allow for high maneuverability of 3830 lead, and higher rates of mid-basal site placement.

  • Lead maneuverability enables mid-basal placement and high rates of selective LBB capture.10
  • Small size minimizes risk of myocardial injury11 during LBBA procedures.

The world’s most durable CSP lead,1,4–6 elevated with new tools

5944RL rotatable connector: a single point of connection for continuous signal monitoring

  • Designed to help achieve target implant location through continuous visualization of ECGs, impedance and 12-lead morphology
  • Eliminates the need to switch between signal monitoring and lead deployment
