Abstract
Official abstract text for this publication.
Electrode arrays for biological implants are disclosed. The present disclosure provides array designs for improving apposition (reducing the space between the array and neural tissue). The present disclosure also provides electrode array designs that can be made approximately spherical to increase the field of view of a visual prosthesis while still maintaining good apposition to neural tissue.
First claim
Opening claim text (preview).
What is claimed is: 1 . An implantable device comprising: a polymer structure, the polymer structure forming perforated tabs along at least one edge; at least one electrode supported by the polymer structure; wherein the perforated tabs along the edge of the polymer structure are curved upward, away from an electrode opening, and embedded in a soft polymer, which is softer than the polymer structure, and bonds to itself through perforations in the tabs, the perforated tabs allowing the edge to be curved up without reducing flexibility. 2 . The implantable device according to claim 1 , further comprising a plurality of electrodes supported by the polymer structure defining an electrode array. 3 . The implantable device according to claim 2 , wherein the electrode array is curved to approximate the curvature of target neural tissue. 4 . The implantable device according to claim 3 , wherein the target neural tissue is the retina. 5 . The implantable device according to claim 3 , wherein the target neural tissue is the brain. 6 . The implantable device according to claim 3 , wherein the target neural tissue is the visual cortex. 7 . The implantable device according to claim 1 , wherein the edges are curved up with a radius of between 0.05 mm and 0.10 mm. 8 . The implantable device according to claim 1 , wherein the polymer structure defines slots separating a plurality of electrodes into leaves suitable to allow the polymer structure to curve spherically. 9 . The implantable device according to claim 8 , wherein the slots are wedge shaped. 10 . The implantable device according to claim 1 , wherein a plurality of electrodes has a variable pitch between electrodes. 11 . The implantable device according to claim 1 , wherein the at least one electrode is an aggregate electrode, including multiple common electrodes connected together by common traces.
