Method of manufacturing a medical electrical lead
First Claim
1. A method of manufacturing a lead (1) having an electrode (22) used to stimulate and sense a body comprising the steps of introducing a substrate (23) into a mold (50) having a mold cavity (54) and positioning a conductive particulate material onto the substrate (23) in the mold cavity (54), the step of positioning a conductive particulate material onto the substrate (23) characterized in that:
- creating a negative pressure in the mold cavity (54) through a first port (62) in the mold (50);
injecting a slurry comprising a binder and a conductive particulate material into the mold cavity (54) during the step of creating the negative pressure in the mold cavity (54);
heating the mold (50) having the substrate (23) and the particulate material in an oven to conjoin the particulates and thereby form an electrode (22);
removing the mold (50) from the oven;
removing the electrode (22) from the mold (50), andassembling the electrode into a lead.

Abstract
A method of manufacturing a lead having an electrode includes the steps of introducing a substrate into a mold, creating a negative pressure in the mold, injecting a slurry comprising a binder and a conductive particulate material into the mold cavity during the step of creating negative pressure in the mold cavity, heating the mold having the substrate and the particulate material in an oven to cojoin the particulates and thereby form an electrode, removing the mold from the oven, removing the electrode from the mold, and assembling the electrode into a lead. The produced lead may be used as a steroid eluting pacing cardiac lead.
