Abstract
An electrode assembly includes a substantially porous element configured to be coupled to an electrode for delivery of electrical current to a patient in a neurostimulation procedure. The substantially porous material defining a contact surface, of which at least a portion contacts the patient during the neurostimulation procedure. A first insulating member is coupled to the substantially porous element and exposed at the contact surface to prevent a portion of the contact surface from contacting the patient to deliver the electrical current during the neurostimulation procedure.
Claims24
An electrode assembly comprising:
- a substantially porous electrode sponge configured to be coupled to an electrode for delivery of electrical current to a patient in a neurostimulation procedure, the substantially porous electrode sponge material defining an outer surface comprising a first portion and a second portion, wherein the first portion of the outer surface contacts the patient during the neurostimulation procedure;
- an electrolytic solution contained within the electrode sponge for facilitating electrical conduction between the outer surface of the sponge and the patient;
- and
- a first insulating member coupled to the substantially porous electrode sponge, the first insulating member being electrically non-conductive and having an outer surface exposed at the outer surface of the substantially porous electrode sponge, the outer surface of the first insulating member together with the first portion of the outer surface of the substantially porous electrode sponge forming a patient contact surface for contacting the patient during the neurostimulation procedure,
- wherein the outer surface of the first insulating member prevents the second portion of the outer surface of the substantially porous electrode sponge from contacting the patient to deliver the electrical current during the neurostimulation procedure.
2 more elements
An electrode assembly comprising:
- a substantially porous element having an outer surface, at least a first portion of which is configured to contact a patient during delivery of electrical current from the substantially porous element to the patient during a neurostimulation procedure, wherein the substantially porous element includes a first layer and a second layer;
- an electrode sandwiched between the first and second layers of the porous element;
- and
- two or more rivets made of electrically insulating material passing through the first layer and the second layer of the substantially porous element to hold the first and second layers portion together,
- wherein each rivet is electrically non-conductive and has a head portion with an outer surface exposed at the outer surface of the substantially porous element, the outer surfaces of the rivets together with the first portion of the outer surface of the substantially porous element forming a patient contact surface for contacting the patient during the neurostimulation procedure, and
- wherein the outer surfaces of the rivets prevent at least a second portion of the outer surface of the substantially porous element from contacting the patient during the neurostimulation procedure, and
- wherein the rivets are positioned so that an innermost portion of each respective head is no further from a closest edge of the substantially porous element than approximately 150% of the head's diameter.
4 more elements
A system comprising:
- a neurostimulation device;
- at least two electrically conductive cables coupled to the neurostimulation device;
- an electrode coupled to the distal end of each respective one of the electrically conductive cables;
- and
- an electrode interface coupled to at least one of the electrodes, each electrode interface comprising:
- a substantially porous electrode sponge physically coupled to the electrode for delivery of electrical current to a patient in a neurostimulation procedure, the substantially porous material defining an outer surface, wherein at least a first portion of the outer contact surface contacts the patient during the neurostimulation procedure;
- and
- a first insulating member coupled to the substantially porous electrode sponge, the first insulating member being electrically non-conductive and having an outer surface exposed at the outer surface of the substantially porous electrode sponge, the outer surface of the first insulating member together with the first portion of the outer surface of the substantially porous electrode sponge forming a patient contact surface for contacting the patient during the neurostimulation procedure,
- wherein the outer surface of the first insulating member prevents at least a second portion of the outer surface from contacting the patient to deliver the electrical current during the neurostimulation procedure.
