Patent ID: 7797055

Claim:
A device for electrostimulation comprising: a proximal end configured for electrical connection to an implantable medical device; an oblong medial section having a first external diameter, wherein said oblong medial section comprises at least one first dielectric outer envelope, at least one first electrical conductor configured to reside within said at least one first dielectric outer envelope, and at least one first electrical stimulation and/or measurement mechanism on a distal area of said oblong medial section wherein said at least one first electrical stimulation and/or measurement mechanism is coupled with said at least one first electrical conductor; a distal section having a second outer diameter, wherein said distal section is coupled with said oblong medial section and wherein said distal section comprises at least one second dielectric outer envelope, and at least one second electrical conductor configured to reside within said at least one second dielectric outer envelope; a distal end coupled with said distal section, wherein said distal end comprises at least one second electrical stimulation and/or measurement mechanism wherein said at least one second electrical stimulation and/or measurement mechanism is coupled with said at least one second electrical conductor; a lumen oriented in a longitudinal direction that passes through at least through the proximal end and said oblong medial section; wherein said first external diameter is isodiametric to said second outer diameter; wherein said at least one first dielectric outer envelope has the same material properties of said at least one second dielectric outer envelope; and, wherein said distal section is configured with a greater flexibility than said oblong medial section with said at least one second dielectric outer envelope configured with at least one indentation in an inner portion of said at least one second dielectric outer envelope to provide said greater flexibility.
