Abstract
A medical lead with at least a distal portion thereof implantable in the brain of a patient is described, together with methods and systems for using the lead. The lead is provided with at least two sensing modalities (e.g., two or more sensing modalities for measurements of field potential measurements, neuronal single unit activity, neuronal multi unit activity, optical blood volume, optical blood oxygenation, voltammetry and rheoencephalography). Acquisition of measurements and the lead components and other components for accomplishing a measurement in each modality are also described as are various applications for the multimodal brain sensing lead.
Claims12
An implantable medical device comprising:
- a lead comprising:
- a lead body having a distal portion configured to be implanted in or on a brain and a proximal portion;
- and
- a plurality of lead components at the distal portion, wherein the plurality of lead components includes a plurality of macroelectrodes, a plurality of microelectrodes, and at least one optical assembly, and are configurable to implement a plurality of different sensing modalities including a first sensing modality and a second sensing modality that uses a common type of lead component as the first sensing modality;
- and
- a host device coupled to the lead and operating in accordance with a timing schedule to implement continuous measurement acquisition during which at least one of the different sensing modalities is implemented to obtain a corresponding measurement, wherein the timing schedule suspends implementation of the first sensing modality during implementation of the second sensing modality.
