                Physicians need a means of differentiating leads when they are routed on the same side of the patient’s head -- Differentiating components routed to left and right sides of the brain and differentiating components routed to two separate targets on the same side of the brain.

Many physicians currently use the existing DBS extension boots (available in both clear and white colors) to differentiate left and right side system components. If the boots are removed from future DBS extension and lead cap designs, the sole means of chronic lead identification will be eliminated. 

            The below-listed concepts provide several methods for the physician to identify left and right side system components in all relevant use cases.  These use cases including during initial implant of system components, during revision of system components and during imaging of the patient outside of the operating room:

·         Sutures of different colors or different numbers of sutures tied around the boot.

·         Supply the lead cap or extension with a suture already wrapped around it that could be cut off if desired

·         Extension connector has feet on the proximal end with numbers printed above.  One foot is trimmed at time of implant to correspond to R, L, etc.  The feet also act as an anchor thereby preventing migration of the extension:

·         Perforated R/L tear tabs:

·         Removable flap on extension with in-situ molded colored beads or laser-marked grooves that can be trimmed or removed if desired:

·         Mold bumps are incorporated into the lead cap which allows the physician to cut off 1, 2 or 3 bumps for multiple leads:

·         A metal piece in shape of an “L” within polymer that can be removed at time of implant if desired.  The metal piece could be a band or tab.

·         Extra polymer piece molded onto the extension’s distal end or radiopaque lead cap that could be removed if desired.  Molded shape = L for Left.

·         Sterile implant accessory band applied after lead/extension implant connection on the proximal end, viewable through imaging with “L” and “R”.

·         Inject applied band physician could place around the lead or extension

·         Band attached to the proximal end of the lead cap that could be then transferred to distal end of lead.  Ensure availability of extra bands – perhaps two-four different colors of bands with “L” vs. “R”.

·         Kits of colored “rubber bands” that loop over the proximal end of the lead during Stage 1.  Can slide them onto the extension connection at Stage 2 (or onto lead cap during Stage 1 – then back onto lead for removal). 

·         Bands could be preloaded onto tunneling tools that could be slid off by the physician

·         Biocompatible tape flag:

·         Elastic roll-on o-ring:

·         Biocompatible material that can paint or stain the white end of the extension.

·         Lead and extension body have 1, 2, 3, 4...
