BATTERY FEEDTHROUGH FOR AN IMPLANTABLE MEDICAL DEVICE

摘要

A battery feedthrough comprises a ferrule having a passage extending from a first side to a second side, a pin extending through the passage, an insulation sleeve disposed between the pin and the ferrule within the passage, there being a first junction between the pin and the insulation sleeve and a second junction between the insulation sleeve and the ferrule, and a coating comprising a polymer disposed over the pin on the first side of the ferrule, wherein the coating is formed by forming a preform comprising the polymer, placing the preform around at least a first portion of the pin on the first side of the ferrule, and melting the preform so that the polymer substantially covers a second portion of the pin, the first junction, a portion of the insulation sleeve, the second junction, and a portion of the ferrule on the first side of the ferrule.
