Spinal Electrodes TRIZ Cases

An electron-to-ion current conversion cell enables direct nerve block, sustaining pain suppression after current stops while limiting paresthesia.

Mechanical loading lets stacked piezoelectric composites generate DC stimulation for spinal fusion without batteries or BMP-related risks.

Releasing winding tension before reflow lets a coiled stimulation lead relax, preventing cable expansion and easing wire connection.

Optical fiber coupling in the IPG header stabilizes reflectometry signals, enabling electrode current adjustment as spinal cord distance changes.

Closed-loop ultrasonic powering and targeted splenic nerve stimulation reduce lead damage, battery replacement, and off-target organ effects.

Percutaneous leads and breakaway connections enable comfortable peripheral nerve stimulation with less pain, fatigue, and daily setup burden.

Ultrasonic power and data links enable long-term brain implants with precise sensing and stimulation while reducing RF heating in tissue.

Harvesting electrical energy from neural tissue, this microneedle stimulator enables battery-free intradural implantation with precise local stimulation.

A mineralized 3D porous graphene foam improves soft-tissue electrode compatibility and supports bone healing through cell proliferation and osteogenic differentiation.

A cantilevered conductive flat piece replaces rigid ceramic adapters to shrink implant connections while preserving flexibility and moisture resistance.

A dual current-mirroring and switched-capacitor stimulator improves cranial nerve current precision while reducing noise for cleaner signal recording.

A deformable sleeve forms the electrode contact face and crimps the supply line in one step, cutting assembly complexity and cost.

Spring-biased lead connectors enable one-handed loading, secure retention, and better alignment during electrical stimulation procedures.

A beta-titanium single conductor coil absorbs up to 400% strain while limiting force transfer, helping keep sacral stimulation electrodes stable.

Alternating charging and measurement modes lets an implantable pulse generator capture CAP signals without interference and maintain closed-loop stimulation.

A laterally positioned power assembly lowers control module height, enabling skull-surface implantation with less bulging and simpler lead routing.

Aligned cable and conductor openings let ring electrodes connect without extra wires, cutting multipolar lead cost and failure risk.
