The various embodiments disclosed herein relate to medical electrical leads. More specifically, certain embodiments relate to leads having one or more drug-eluting components that are overmolded or otherwise positioned on the lead. Other embodiments relate to leads having one or more patterned surfaces, including some leads with one or more patterned surfaces over which one or more drug-eluting components are positioned. Further implementations relate to leads having one or more overmolded patterned surfaces, including some embodiments in which the overmolded surfaces contain at least one drug-eluting component.

Overmolded components for implantable medical leads and related methods

A cardiac lead includes a lead body that defines a passage, a conductive element that extends through the passage, and a fixation assembly. The fixation assembly includes a threaded member threadably engaged with the conductive element such that rotation of the threaded member causes the threaded member to translate longitudinally relative to the conductive element. A fixation element has a first end coupled to the threaded member and a second end coupled to a fixed location. A resilient membrane extends over the fixation element such that rotation of the threaded member affects the resilient membrane radially with respect to the conductive element.
