Abstract
Enclosures for implantable medical devices are machined from biocompatible materials using processes such as electric discharge machining and/or milling. Material is machined to create an enclosure. The enclosure may include an enclosure sleeve that has top and bottom caps added where the enclosure sleeve is machined either as a whole or as two separate halves that are subsequently joined together. During construction, circuitry is installed and where the enclosure includes an enclosure sleeve, the open top and bottom may be closed by caps while a connector block module may be mounted to the complete enclosure. The machining process allows materials that are typically difficult to stamp, such as grade 5 and 9 titanium and 811 titanium, that are beneficial to telemetry and recharging features of an implantable medical device to be used while allowing for an enclosure with a relatively detailed geometry and relatively tight tolerances.
