A nerve electrode cuff includes an electrode and a cuff body.

대표청구항 ▼

1. A nerve electrode assembly comprising: an electrical lead including a first portion and a second portion;an elongate body housing the first portion of the electrical lead within an interior of the elongate body, and with the second portion of the electrical lead extending proximally from a proximal end of the elongate body, the elongate body including: a recess defined in a first side of the elongate body, the recess including a mouth facing away from the proximal end of the elongate body and a closed end opposite to, and spaced proximally from, the mouth; anda distal contact portion including an electrode contact, the electrode contact in communication with the electrical lead and exposed at a surface of the distal contact portion, wherein the distal contact portion is located distally relative to the mouth of the recess and forms a generally arcuate shape; anda resilient arm including a distal portion and a generally arcuate proximal portion extending from the distal contact portion of the elongate body, the arm having a length sufficient to cause the distal portion to extend in a first orientation proximally beyond the distal contact portion of the elongate body and into the recess upon removable, slidable insertion of the distal portion of the arm into the recess, wherein a combination of the proximal portion of the arm and the distal contact portion of the elongate body define a lumen. 2. The nerve electrode assembly of claim 1, wherein the recess extends generally parallel to the first side of the elongate body, wherein the mouth of the recess is oriented in substantially the same direction as a generally concave surface of the distal contact portion of the elongate body, and wherein the recess defines a slot extending proximally from the mouth toward the proximal end of the elongate body to the closed end of the recess. 3. The nerve electrode assembly of claim 1, wherein the distal portion of the arm has a length at least two times longer than an arc length of the proximal portion of the arm. 4. The electrode assembly of claim 1, wherein the exposed electrode contact defines a first area and a generally circular shape, and wherein the distal contact portion defines an electrically non-conductive surface surrounding the electrode contact that defines a second area with the second area being substantially larger than the first area. 5. The nerve electrode assembly of claim 1, wherein the elongate body and the first portion of the electrical lead extend in a substantially single direction throughout a length of the elongate body, with the substantially single direction being generally parallel to the first orientation in which the distal portion of the resilient arm extends from the elongate body. 6. A nerve electrode assembly comprising: an electrical lead;an elongate body housing the electrical lead with the electrical lead extending at least proximally from a proximal end of the elongate body, the elongate body including: a recess defined in a first side of the elongate body and including a mouth facing away from the proximal end of the elongate body; anda distal contact portion including an electrode contact communication with the electrical lead, wherein the distal contact portion is located distally relative to the mouth of the recess and forms a generally arcuate shape,wherein the elongate body includes a second side generally opposite the first side with the first side and the second side defining a general wedge shape having a narrow portion adjacent the proximal end of the elongate body and a wider portion adjacent the distal contact portion of the elongate body; anda resilient arm including a distal portion and a generally semicircular proximal portion extending from the distal contact portion of the elongate body, the arm having a length sufficient to cause the distal portion to extend proximally beyond the distal contact portion of the elongate body and into the recess upon removable, slidable insertion of the distal portion of the arm into the recess, wherein a combination of the proximal portion of the arm and the distal contact portion of the elongate body define a lumen. 7. A nerve electrode assembly comprising: an electrical lead including a first portion and a second portion; andan elongate body housing the first portion of the electrical lead with the second portion of the electrical lead extending at least proximally from a proximal end of the elongate body, the elongate body including: a first engaging portion defined in a first side of the elongate body; anda contact portion at which the first portion of the electrical lead terminates to define and expose an electrode contact at one part of a surface of the contact portion with the entire electrode contact in alignment with a longitudinal axis of the electrical lead, wherein the contact portion is located distally relative to the first engaging portion and forms a generally arcuate shape; anda resilient arm including a distal portion and a generally arcuate proximal portion extending from the contact portion of the elongate body, the arm having a length sufficient to cause the distal portion to extend proximally beyond the contact portion of the elongate body and to be selectively engageable relative to the first engaging portion, wherein a combination of the proximal portion of the arm and the contact portion of the elongate body define a lumen. 8. The nerve electrode assembly of claim 7, wherein the first engaging portion includes a recess having a mouth facing away from the proximal end of the elongate body. 9. The nerve electrode assembly of claim 7, wherein the contact portion is disposed between a proximal end and a distal end of the elongate body, wherein the exposed electrode contact defines a first area, and wherein at least a portion of the contact portion includes an electrically non-conductive portion surrounding the exposed electrode contact to define a second area substantially larger than the first area.
