A biomimetic electrode material including a fibrous matrix including a conductive polymer and an ion conducting polymeric material is described. The biomimetic electrode material may be used in a number of body-implantable application including cardiac and neuro-stimulation applications. The biomimetic electrode material can be formed using electrospinning and other related processes. The biomimetic electrode may facilitate efficient charge transport from ionically conductive tissue to the electronically conductive electrode and may induce surrounding tissue to attach or interface directly to the implanted device, increasing the biocompatibility of the device.

Fibrous electrode material

A medical electrical lead and body implantable electrode suitable for a variety of medical applications are disclosed. In general, the electrode includes a composite material having particles of pseudo-capacitive material, such as iridium oxide, dispersed within a polymer matrix including a polyelectrolyte. The polymer matrix can also include a conductive polymer doped with an excess of the polyelectrolyte. The composite may used to form the electrode itself or an electrode coating. The presence of a pseudo-capacitive material within the composite may increase the charge-storage capacity of the electrode and may allow for safe deliveries of charge densities within an electrochemical window suitable for pacing a patient's heart.
