Medical device for sensing and or stimulating tissue
Devices, methods and systems for transmitting signals through a device located in a blood vessel of an animal for stimulating and/or sensing activity of media proximal to the devices. The media can include tissue and/or fluid. A method of controlling an apparatus in communication with a brain machine interface. The method can include measuring a first neural activity in a first neural area and measuring a second neural activity in a second neural area. The first neural activity can be associated with a first intent. The method can include creating and delivering, via the processor, one or more first control signals to the apparatus upon comparing the second neural activity with the first neural activity, and confirming, based on this comparison, that the second neural activity is associated with the first intent.
1. A method of controlling an apparatus in communication with a brain machine interface, the method comprising:
measuring a first neural activity in a first neural area associated with a first intent to control the apparatus, where measuring the first neural activity comprises using a first sensor;
measuring a second neural activity in a second neural area using a second sensor; and
delivering, via a processor, one or more control signals to the apparatus upon confirming that the second neural activity is associated with the first intent,
where the first neural area is different than the second neural area.
2. The method of claim 1 , further comprising:
decoding, via the processor, the first intent from the measured first neural activity; and
decoding, via the processor, a second intent from the measured second neural activity, where the delivering comprises delivering the one or more control signals to the apparatus upon confirming that the second is associated with the first intent.
3. The method of claim 2 , where decoding the first and second intents comprises referencing previously measured neural activities stored in a memory.
4. The method of claim 1 , further comprising repeating the measuring until at least one of the one or more control signals is delivered to the apparatus.
5. The method of claim 1 , where the delivering comprises delivering the one or more control signals to the apparatus to control a first parameter and/or a second parameter of the apparatus.
6. The method of claim 1 , where the first sensor is proximate or in a first neural area and where the second sensor is proximate or in a second neural area.
7. The method of claim 6 , where the first and second neural areas are in a brain.
8. The method of claim 1 , further comprising:
determining a desired parameter of the apparatus;
calculating a control correlation between the measured first neural activity and the desired parameter; and
adjusting a user control percentage and a computer control percentage of the apparatus.
9. The method of claim 8 , where the adjusting comprises increasing the user control percentage and decreasing the computer control percentage and/or where the adjusting comprises decreasing the user control percentage and increasing the computer control percentage.
10. A method of positioning an electrode array device for detecting, measuring, recording, stimulating, decoding, and/or modulating brain activity of a brain, the method comprising:
providing a scaffold comprising one or more substrate members, the one or more substrate members embedded with conductive materials configured to be in electrical communication with an external device, the scaffold attached to a communication conduit that facilitates communication between conductive materials and a control unit; and
delivering a flexible hollow delivery instrument through a vessel, the flexible hollow delivery instrument configured to translate the scaffold and its one or more substrate members from the vessel to a target location within a deposition point of the brain;
wherein the scaffold the one or more substrate members are configured to be confined to a small volume for containment in the flexible hollow delivery instrument during translation to the deposition point;
deploying the one or more substrate members to the deposition point such that the one or more substrate members are further configured to expand over a selected area such that the conductive materials electrically couple with a neural tissue at the deposition point while the communication conduit remains within the vessel; and
where the external device and the conductive materials are configured for the transfer of electrical signals between the deposition point of the brain and the external device.
11. The method of claim 10 , the conductive materials are further configured to enable sensing and relaying of cortical activity neural activity.
12. The method of claim 10 , wherein the external device is a brain-computer interface.
13. The method of claim 10 , further comprising an implantable wireless receiver configured to enable wireless communication with the external device.
14. The method of claim 10 , wherein the flexible hollow delivery instrument comprises a catheter system.
15. The method of claim 14 , wherein the scaffold is configured to be compressed into the catheter system and can be expanded after deployment from the catheter system.
16. The method of claim 10 , wherein the deposition point is a motor cortex.
17. The method of claim 10 , wherein the deposition point is a sensory cortex.
18. The method of claim 10 , wherein the deposition point is a brain structure.
