SenSight™ directional leads
Deep brain stimulation (DBS) directional
lead system
The first-of-its-kind SenSight™ directional DBS lead system combines the benefits of directionality with the power of sensing. Built with proprietary materials, components, and processes, the SenSight™ directional lead and SenSight™ extension work seamlessly with the Percept™ PC and Percept™ RC neurostimulators to enhance detection of local field potentials (LFPs), which are 1 million times smaller than DBS stimulation pulses.1

Overview
A system designed around you
With your collaboration and insights, we’ve designed every component of our DBS directional lead system — including the lead, the burr hole device, the extension, and everything in between. It's the only DBS directional lead system with 3T and 1.5T MR Conditional† eligibility.
SenSightTM directional leads
1. 1-3-3-1 electrode configuration to more precisely direct the stimulation
2. 1.5mm and 0.5mm electrode spacing options to suit various targeting and patient needs
3. Completely insulated orientation markers to guide directional programming
SenSight™ directional lead —
proximal end features
4. Proximal end of lead inserted into extension
5. Laser-etched markers on the proximal end for identification of left and right leads with bilateral implants
6. Laser-etched insertion line on the lead body, which provides visual confirmation of complete insertion — providing confidence in the connection
SenSight™ extension
7. Single set screw connection on a non-active contact to minimize steps and protect therapeutic delivery
8. Left and right laser-etched markers and radiopaque marker. Laser-etched markers on the proximal end (not shown) and distal end for bilateral implants, for identification of left and right extensions. Extensions with the laser-etched markers also include a radiopaque marker visible under CT, fluoroscopy, X-ray, and O-arm™ Imaging System, for distinguishing with bilateral implants§
SenSight™ burr hole device
- 14.7% lower profile|| — for your patient’s comfort
- 57% improved lead tip stabilization#
- Clip designed with vertically elongated securing mechanism with ribs to increase the surface area holding force and minimize lead rotation once secured
- Flexible — designed to be placed in any orientation and conform to the patient’s skull

a. All measurements are approximate.
b. Electrical resistance of this device only.
c. Electrical resistance is proportional to lead length: long lengths have higher resistance that may limit the amplitude.
d. Discuss allergies or other intolerances related to the materials of construction with the patient before the procedure.
e. Tested for category 1A or 1B carcinogenic, mutagenic, or toxic for reproduction (CMR) substances, and endocrine disrupting chemicals (EDC). No known CMRs or EDCs found for the materials and substances listed in this table.
SenSight™ directional leads identified with the letter M after the length (e.g. B3300533M), include 2 bilateral markers. Bilateral markers help differentiate between hemispheres when 2 leads are implanted.

‡ Excluding the distal connector end, the extension body diameter is approximately 26.7% smaller than Medtronic extensions 37085 and 37086.
§ Leads and extensions with markers are identified with model numbers ending in M. The extension also has a marker near the proximal end (not pictured).
|| As compared to the Stimloc™ burr hole device.
¶ When compared to the Model 37085 and 37086 extensions.
# Based on a study in an animal model, the SenSight™ directional lead system provided on average a 57% lead tip stability improvement compared to Medtronic’s legacy lead system. Animal data may not be indicative of clinical performance.
