Tines made of degradable materials with decreasing removal forces: An option to facilitate passive-fixation leads extraction from the very beginning?

•PLGA/PLCL blends with mass ratio of 25:75 (PLGA25-PLCL75) can make tines for passive fixation lead.•Tines made of PLGA25-PLCL75 were successfully assembled on the traditional lead body.•Tines made of PLGA25-PLCL75 decreased the lead removal force in dogs.•Tines made of PLGA25-PLCL75 brought excellent fixation stability in dogs.•Degradable tines likely facilitate lead extraction via simple manual extraction.
