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; and
a 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; and
a 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.

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; and a 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; and a 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; and an 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; and a 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; and a 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. - View Dependent Claims (8, 9)
