Balloon Catheter TRIZ Cases
- Multilayer Balloon Catheter for Pressure Resistance and Operability
Multilayer balloon films preserve pressure resistance while improving catheter operability.
- Flexible Balloon Blade Pad for Side-Bending Lesion Cutting
Aligned flex points in the polymeric pad let balloon-mounted blades navigate curved vessels while cutting or scoring lesions.
- Multilayer Catheter Balloon for Thin-Wall Volume Retention
Blow-molded PUR balloons with EVOH or PVDC barriers limit permeability, preserving volume and sealing while adapting to body movement.
- Guide Wire With Recessed Curved Tip for Stenosis Penetration
Recesses in the curved distal tip create catching edges that improve stenosis penetration while preserving guide wire passage.
- Composite Medical Balloon With Adhesive-Free ePTFE–Thermoplastic Bonding
Stretch blow molding bonds porous ePTFE to thermoplastic layers without adhesives.
- Angioplasty Balloon Snare for Small-Vessel Wire Capture
This case uses a compliant balloon lumen to capture and move wires, simplifying procedures while protecting vessel linings.
- Lockable Balloon Catheter for Intravascular Guidewire Stability
A balloon catheter locks onto the guidewire near the target site, reducing displacement and vessel damage during device delivery.
- Catheter Pump Motor Seals for High-Speed Fluid Ingress Protection
Shaft seals and fluid cooling protect catheter pump motors while supporting high-flow operation and fluid separation.
- Arterial Catheter Photodynamic Therapy for Plaque Recurrence
This case uses catheter-mounted light emitters and a photosensitizer to stabilize plaque without occluding arterial blood flow.
- TAVI Valve Inflation Programming for Material Variation and Precise Sizing
Stored variation data adjusts balloon inflation for precise TAVI valve sizing.
- Balloon Catheter With Serrated Strips for Distal Lesion Crossing
Serrated strips and composite shafts improve pushability, torque transmission, and energy delivery for crossing distal lesions.
- Balloon Catheter Crystallinity Gradient for Distal Flexibility
Lower distal crystallinity preserves proximal hardness while improving flexibility and reducing buckling during balloon catheter navigation.
- Balloon Catheter Heating with Feedback for Stable Surface Temperature
A shaft-mounted heater and temperature sensors regulate liquid heating to maintain a stable balloon surface temperature during ablation.
- Prosthetic Heart Valve Inward Commissure Supports for Smaller Delivery
This case shows how inward commissure supports reduce leaflet abrasion while a collapsible valve frame enables smaller catheter delivery.
- Balloon Occlusion Catheter Drives Retrograde Vessel and Graft Imaging
Blocking downstream blood flow lets contrast move retrograde, avoiding manual compression and reducing operator radiation exposure.
- Cardiac Valve Double-Helix Anchoring Against Outflow Obstruction
This case uses segmented, controlled-expansion anchoring for catheter delivery while reducing outflow obstruction and valve leakage.
- Occlusion Catheter Photodynamic Therapy for Abdominal Aneurysm Repair
Isolate the aneurysm, infuse therapeutic fluid, and apply light to stiffen the vessel wall.
- TAVI Stent Apposition With Integrated OCT Imaging
An OCT catheter within a transparent TAVI sheath provides real-time apposition feedback to limit leakage and annular rupture risk.
