Transvascular Endocardial Electrodes TRIZ Cases
- Implantable Lead with Disconnectable Mapping Electrode
Disconnecting the mapping electrode after fixation reduces contact surface area, lowering energy consumption and tissue trauma.
- Transvascular Cardiac Nerve Stimulation via Sympathetic Activation
Electrode positioned in coronary sinus stimulates sympathetic nerves to release norepinephrine for improved heart muscle contractions.
- Electrothrombosis Guide Wire for Stable Aneurysm Clotting
A guide wire device uses constant current and thermal effects to induce thrombus formation.
- Deflectable Tubular Delivery Device for Leadless Pacemaker Positioning
Nested deflectable tubular members orient a leadless pacemaker against the ventricular septum, reducing cardiac perforation risk during deployment.
- Pacing Tool Compressible Contact Guidewire Interface
A pacing tool uses a compressible electrical contact to establish reliable electrical connection with a guidewire for medical procedures.
- Leadless Pacing Device Coronary Sinus Segmentation
Segmented housing and distal extension enable multi-chamber cardiac sensing while preserving coronary sinus blood flow.
- Coiled Electrode Tether Force Inversion for Implantable Lead Insertion
A tether line transfers pulling force as pushing force to a coiled electrode during implantation.
- MRI Implantable Lead Multi-Layer Coil Segmentation
Alternating insulated and non-insulated coil segments stabilize DC resistance, reducing RF heating in MRI implantable leads.
- Snare Closed Loop S-Curve Geometry for Cardiac Lead Removal
S-curve geometry enables predictable capture of implanted cardiac leads, reducing procedure time and patient risk during removal.
