SYSTEM AND METHOD FOR PROVIDING A MEDICAL LEAD BODY

摘要

An implantable lead 100 and lead body 120, method of manufacturing the same, and a system and method for stimulating a portion of a body is disclosed. In one advantageous embodiment, a lead body assembly 115 is formed by placing an inner layer of extrusion material 410 on a mandrel, wrapping a plurality of conductors 420 coated with extrusion material 430 around the inner layer 410, and placing an outer layer of extrusion material 440 over the plurality of conductors 420. Heat shrink tubing is placed over the lead body assembly 115 and the lead body assembly 115 is heated to melt the extrusion material (410, 430, 440). The melted extrusion material is compressed around the plurality of conductors 420. The assembly is then cooled and the heat shrink tubing is removed. The solidified extrusion material forms a protective wall 510 that encapsulates the plurality of conductors 420 in the lead body 120.
