Medical lead body configurations that reduce conductor flexural fatigue. The various lead body embodiments include a support section and can also include other features such as a semi-straight portion of a lumen or semi-straight sides that optimize the reduction in conductor flexural fatigue.
摘要:
A method of manufacturing a medical electrical lead includes molding a lead body pre-form, stringing an electrode onto the pre-form and overmolding the pre-form with a polymer to form a lead body portion. The pre-form has a proximal end, a distal end and at least one lumen extending between the proximal and distal ends. At least one asymmetric region of the pre-form has a transverse cross-section that has a non-circular outer dimension. The overmolding causes the asymmetric region to become substantially circular.

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.

A medical electrical lead includes a tapered distal tip having a tapered drug-eluting component incorporated therein. The drug-eluting component can be an overmolded drug-eluting collar or a pre-molded drug eluting collar. The drug-eluting collar is disposed in a recess formed in the tapered distal tip and maintains the overall tapered profile of the distal tip.
