Key result
Medtronic devices linked to lower failure rates and damage versus Boston Scientific and St. Jude.
Why the study?
Assessing damage to leads and pulse generators across various exposure times is important for developing cardiac devices and improving future device design.
Population
65 retrieved cardiac devices and 136 leads from different manufacturers
Comparison
Devices and leads from Medtronic vs St. Jude Medical-Abbott vs Boston Scientific

Explant data suggest Medtronic leads resist damage better; leaves open whether this affects clinical outcomes or device selection.
Observational (n=65)
p-value: p=0.0399
Analysis of retrieved cardiac devices reveals scratching as the primary damage mode, with Medtronic leads demonstrating greater resistance to damage compared to other manufacturers.
Tarun Goswami (2019) conducted an observational in Implantable cardiac devices (n=65). Medtronic cardiac devices and leads vs. Boston Scientific and St. Jude Medical devices and leads was evaluated on Pulse generator damage score (p=0.0399). Medtronic cardiac devices and leads demonstrated significant resistance to damage modes and lower failure rates compared to Boston Scientific and St. Jude Medical devices.
