Abstract: A biostimulator, such as a leadless cardiac pacemaker, including a fixation element and an electrode mounted on a resilient scaffold, is described. The fixation element and the resilient scaffold are coupled to a housing of the biostimulator. The resilient scaffold can support the electrode against a target tissue at a location that is radially offset from a location where the fixation element anchors the housing to the target tissue. A flexibility of the resilient scaffold allows the electrode to conform to a shape and movement of the target tissue when the housing is rigidly fixed to the target tissue by the fixation element. The resiliently supported electrode that is radially offset from the anchor point can reliably pace the target tissue without piercing the target tissue. Other embodiments are also described and claimed.
