  • Patent number: 11992676
    Abstract: A device for the active fixation of an implantable medical lead includes a housing, a tine assembly, and rotatable shaft. The housing includes a proximal end for connecting to the lead and a distal end opposite the proximal end. The housing defines a housing lumen having a longitudinal axis extending between the proximal end and the distal end. The tine assembly is disposed within the housing lumen. The tine assembly includes at least one tine configured to self-bias from a linear configuration within the housing to a curved configuration outside of the housing. The rotatable shaft extends through the housing lumen. The shaft is configured to engage the tine assembly such that rotation of the shaft transitions the at least one tine between the linear configuration and the curved configuration.
