Provided is a medical apparatus for a patient comprising an external system and an implantable system. The external system can be configured to transmit one or more transmission signals, each transmission signal comprising at least power or data. The implantable system can be configured to receive the one or more transmission signals from the external system. The external system comprises a first external device comprising at least one external antenna configured to transmit a first transmission signal to the implantable system. The implantable system comprises a first implantable device comprising at least one implantable antenna configured to receive the first transmission signal from the first external device. At least one of the external antenna or implantable antenna comprises an antenna assembly comprising: at least one transmitting/receiving antenna; and at least one shielding element positioned between the at least one transmitting/receiving antenna and an interfering component.

Stimulation apparatus

A stimulation system for a patient is provided. The system comprises: at least one implantable device comprising at least one implantable antenna; and an external device comprising at least one external antenna, wherein the at least one external antenna transfers power to the at least one implantable antenna. The at least one implantable device delivers therapy to the patient. A patient attachment device or body covering positions the at least one external antenna relative to the patient.

Devices and methods for positioning external devices in relation to implanted devices

A medical apparatus for a patient comprises an external system and an implantable system. The external system is configured to transmit one or more transmission signals, each transmission signal comprising at least power or data. The implantable system is configured to receive the one or more transmission signals from the external system, and to deliver stimulation energy to the patient. Methods of delivering stimulation energy are also provided.

An exemplary cochlear implant includes a communication facility configured to receive at least a first data word and a second data word in series from a sound processor by way of a forward-telemetry link and a processing facility communicatively coupled to the communication facility and configured to 1) use the first data word to dynamically determine an address associated with an electrode by way of which a stimulation pulse is to be applied during a time slot of a stimulation frame and 2) use the second data word to determine an amplitude of the stimulation pulse that is to be applied by way of the electrode during the time slot of the stimulation frame. Corresponding systems and methods are also disclosed.
