Abstract
A flexible-base electrode array for implantation within neural tissue, method of making the electrode array and use thereof, is provided. A surrogate neural tissue, method of making same and use thereof, is further provided. The use of the present flexible-base electrode array for implantation into the surrogate neural tissue for stimulation or recording neural activity, wherein the array is biocompatible with the surrogate tissue.
Claims19
An electrode array for implantation in a target neural tissue, the array comprising:
- a flexible biocompatible elastomer base having a modulus of elasticity of up to approximately 150 MPa;
- and
- at least one microwire electrode protruding from the base, for implantation into and biocompatible with the target neural tissue;
- wherein the base interfaces with the surface of the target neural tissue and the electrodes penetrate into the target neural tissue.
“A method of implanting an electrode array into target neural tissue, comprising:
- a) penetrating at least one microwire electrode of the electrode array into the target neural tissue;
- and b) interfacing a flexible biocompatible elastomer base from which the at least one microwire electrode protrudes with a surface of the target neural tissue”.
An electrode array for implantation in a target neural tissue, the array comprising:
- a flexible biocompatible elastomer base having a modulus of elasticity of up to approximately 150 MPa;
- and
- at least one multi-contact cylindrical electrode protruding from the base, for implantation into and biocompatible with, the target neural tissue;
- wherein the base interfaces with the surface of the target neural tissue and the electrodes penetrate into the target neural tissue.
