Tracheae TRIZ Cases
- 3D-Printed Cartilage Scaffold With Graded Pores for Load-Bearing Repair
Graded micropore and macropore regions help patient-specific cartilage implants balance load support, cell colonization, and scaffold degradation.
- Acellular Tubular Conduits With Stent-ECM Composite Support
A stent encased in decellularized extracellular matrix forms a stable conduit that reduces leaks, immune response, and long-term urinary complications.
- Tongue Base Implant Anchoring to Mandible for OSA Relief
Barbed expandable anchors secure tongue base to mandible, eliminating cheese cutter effect and maintaining airway patency.
- Variable Frequency Electrolarynx with Microcontroller Tone Control
Microcontroller-driven tone variations eliminate robotic speech monotony while a multi-function encoder simplifies volume and pitch adjustments.
- Compressible Adaptor and Reed Module for Natural Speech
Mechanical vibration of a reed module produces natural speech sounds, replacing robotic electronic synthesis with affordable hardware.
- Flexible Vocal Cord Implant with Deflecting Passageway
A flexible vocal cord implant enables safe medialization while accommodating other medical devices.
- External Tracheal Prosthesis with Elastic Biasing for Airway Support
An external prosthesis uses elastic biasing to apply tension on the tracheal membranous portion.
- Customized Airway Stents for Gradual Stenosis Dilation
Sequentially implanted customized airway stents gradually dilate stenotic regions, avoiding complications from poorly fitting discrete devices.
- Electrolarynx Voice Coil Wear Reduction via Non-Magnetic Cup
Replacing the magnetic centering cup with a non-magnetic intermediary eliminates gravitational wear on the voice coil, extending device lifespan.
- Voice Prosthesis Sealing Rim Minimizes Candida Growth
A voice prosthesis uses a sealing rim between the valve disc and seat to minimize interaction area.
- Voice Grafting Machine Learning for Natural Speech
Machine learning grafts patient articulation onto healthy phonation sources to synthesize speech waveforms in real time.
- Vibration Generating Unit for Vocal Cord Signal Processing
Piezoelectric vibration generating unit converts bio-signals into mechanical vibrations near the vocal cords.
- Magnetic Vocal Fold Manipulator for Reversible Lateralization
A magnetic implant system adjusts vocal fold position through controlled field interaction.
- Electrolarynx Device Using Breath and Jaw Sensors for Natural Speech
Replacing mechanical buzzing diaphragms, this electrolarynx uses breath and jaw sensors to eliminate distortion and improve speech intelligibility.
- Reverse Motion Linkage for Vocal Fold Paralysis
A reverse motion linkage translates working vocal fold movement to the paralyzed side.
- Segmented Phonatory Implant for Tracheoesophageal Fistula Insertion
Segmented rigid portions with radial shoulders anchor in the tracheoesophageal wall, preventing displacement and fluid leaks during voice prosthesis insertion.
- Voice Prosthesis Gel Cap Atraumatic Insertion
Dissolving the gel cap releases the esophageal flange to expand, eliminating tissue trauma while ensuring reliable retention.
