摘要:
A solventless method for forming a coating on a medical electrical lead is described. The method includes combining particles of a therapeutic agent with a polymeric material in a flowable form in the absence of a solvent to form a uniform suspension. A predetermined amount of the suspension is dispensed onto a portion of the lead and is then cured to form the therapeutic agent eluting layer. Additional layers such as a primer layer, fluoro-opaque layer and/or a topcoat layer can be formed using the solventless method. Employing a solventless method may avoid contraction of the layer being formed due to solvent evaporation during the curing process, and may facilitate greater control over the thickness of the therapeutic agent eluting coating.
