Sprint Quattro
Proven performance didn’t happen by chance.
From lead design to active product monitoring, intentional choices and proactive steps were taken to ensure the reliability of the Sprint Quattro family of leads.
Let us show you Why Quattro.
Proven by Active Monitoring
Sprint Quattro® has 10 years of proven performance and the most extensive in vivo experience in the market.
In Vivo Experience
Important Safety Information
Surgical complications, such as cardiac perforation, may occur and care must be taken when placing and positioning a cardiac lead.

Designed for Reliability
Purposeful design decisions were made to produce a lead that lasts.
From the asymmetrical design to the materials selection, the Sprint Quattro was designed for reliability and tested in a variety of different ways to withstand in vivo conditions.
Important Safety Information
Surgical complications, such as cardiac perforation, may occur and care must be taken when placing and positioning a cardiac lead.
Asymmetrical Design Advantage
Compared to a symmetrical lead design, offsetting the coil and cable offers several advantages1:
- Promotes reduced tip pressure and lead body
- Allows for greater insulation thickness between conductors to help reduce the risk of insulation failure
- Facilitates increased lead strength allowing room for 2 cables (1 cable for the 6935(M)) with a 7x7 configuration (1x19 for 6944)
- Designed to reduce stresses on the conductors in a crush situation allowing for individual compression lumens to help reduce the risk of failure

Insulation
All silicone is not the same.
Many types of silicone were tested and one high performance silicone was purposefully selected for the demands of the Quattro ICD leads in vivo. Medtronic conducts secondary processing on this silicone via a proprietary method to enhance resistance to in vivo challenges such as creep (conductor externalization), abrasion, and axial compression (crush).

True Bipolar Advantage
Medtronic’s Sprint Quattro leads have true bipolar sensing, which compared to integrated bipolar may:
- Create a smaller antenna, by sensing between the lead tip and the ring electrode, which may reduce oversensing1,2
Only Medtronic Devices have programmable sensing, allowing you to program true or integrated bipolar with any true bipolar lead, to provide more options.

DF4 Connector: Tested Above and Beyond Industry Standards
Medtronic designed new testing methodology, surpassing industry standards and utilizing advanced finite element analysis to simulate worst-case scenario use conditions, when developing the DF4 Connector for the Sprint Quattro lead.
Important Safety Information
Surgical complications, such as cardiac perforation, may occur and care must be taken when placing and positioning a cardiac lead.
| Implant Geometry Test Approximately 15% of patients have an implant that gives an opportunity for meaningful connector challenge. This test was delivered from real clinical use conditions. |
 |
| Lead Orientation and Amplitude Curvature Test Finite Element Analysis simulates worst-case curvature amplitude and lead orientation. |
 |
| High Activity Levels Test To simulate worst-case levels of activity, 2.5 million cycles, which is equivalent to one arm raise each minute every day for 10 years, were completed. |
 |
| Voltage Isolation Test Medtronic's high-voltage isolation goes above and beyond the industry standard (2x operating voltage). |
