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.Type: ApplicationFiled: July 14, 2017Publication date: January 18, 2018Inventors: Steven T.

Publication number: 20180015291Abstract: An implantable medical device having a hollow housing and a connector housing connected (e.g., rigidly) together, each containing electrical components. The components contained in the hollow housing include a receiver for wireless communication. The components contained in the connector housing include an antenna electrically connected to the receiver and configured to receive electromagnetic waves having a frequency greater than 100 MHz. The receiver/antenna allows the receipt of data in the MICS frequency band. The electrical components arranged in the connector housing additionally include a resonant circuit having a coil and a capacitor which is inductively coupled to the antenna. The resonant circuit is matched to magnetic alternating fields in a frequency range between 5 kHz and 50 MHz, preferably having a resonance frequency between 5 kHz and 50 MHz. The resonant circuit is suitable for data communication in the near field of the implantable medical device via magnetic alternating fields.Type: ApplicationFiled: June 29, 2017Publication date: January 18, 2018Inventors: Christian Moss, Christian Gothe, Thomas Finnberg
