Internal Electrodes TRIZ Cases
- Electroporation-Based Catheter Infection Control for Biofilm Disruption
Controlled electrical pulses disrupt bacterial biofilms on dialysis catheters and vascular access devices, reducing reliance on chemical antimicrobial protection.
- Ocular Bioimpedance Monitoring for Non-Invasive Cerebral Blood Volume
Localized ocular electrodes measure brain bioimpedance non-invasively, tracking cerebral blood volume for earlier cerebral autoregulation assessment.
- Active Fixation Tines for Low-Trauma Implantable Device Anchoring
Deployable active tines anchor implantable devices to patient tissue with minimal damage, helping maintain reliable electrical contact.
- Laminate Probe Biostimulator for Controlled Deep Septal Pacing
A laminated conductive-and-substrate probe helps a biostimulator control deep septal penetration while reducing buckling and tissue trauma.
- Electric-Field Shaping Paddle Leads for Selective Tumor Treatment
Multiple independently controlled electrodes shape therapeutic fields at tumors, disrupting tubulin and septin alignment to halt mitosis while limiting healthy-tissue exposure.
- Neurostimulation With Time-Interleaved Bipolar Electrode Scanning
Time-interleaved scanning across bipolar electrode pairs broadens stimulation coverage and helps maintain therapy consistency despite patient movement.
- Leadless Cardiac Pacemaker Backup Fixation Against Migration
Primary fixation is backed by tines, hooks, or expandable elements that prevent downstream migration and support retrieval after dislodgement.
- Acoustic Sensor Integration for Synchronized Respiratory Stimulation
Integrated acoustic sensing synchronizes hypoglossal stimulation with breathing.
- Modulated Neurostimulation Pulse Sequences for Reduced Accommodation
This case converts tonic neurostimulation into modulated pulse sequences, varying parameters to limit accommodation and lower energy needs.
- Transclival Tumor-Treating Field Implant for Deep DIPG Targeting
Transclival electrodes near the pons improve field penetration and coverage, while removable components support MRI compatibility.
- Pulsed Electric Field Generator for Closed-Loop Tissue Ablation
Current sensing and resistor modulation adapt pulse waveforms to control tissue ablation while limiting excess energy delivery.
- Microelectrode Array Feedback for Precise Neural Stimulation
A microelectrode array compares neural signals with a reference, then repeats stimulation and measurement to avoid unnecessary treatment.
- Neuromodulation Guidewire Sensing for Real-Time Denervation Feedback
Sensing guidewires add real-time feedback to controlled denervation procedures.
- EMG-Guided Vagus Nerve Stimulation Titration for Heart Rate Stability
EMG-guided vagus nerve stimulation titration limits cardiac side effects.
- Insulated Electrode Design for Alternating-Field Biofouling Control
An alternating electric field limits sorption and biological films on implanted devices while insulation prevents harmful current flow.
- Aneurysm Constriction With Vessel-Wall Stimulation for Healing
Gentle constriction and vessel-wall stimulation support aneurysm healing with less tissue injury.
