Balloon Catheter TRIZ Cases

A balloon catheter delivers pharmacological agents during ablation to prevent pulmonary vein stenosis and neointimal hyperplasia.

Multi-material blow molding creates a tapered balloon that maintains consistent hoop stress and radial expansion for improved deliverability.

An inflatable device with adhesive cavities compresses the right heart to reduce tricuspid regurgitation without invasive open-heart surgery.

Segmented torus balloon activation enables precise barb deployment for stable stent-valve positioning while maintaining blood flow through the mitral annulus.

Orientation sensors detect device tilt to guide users, eliminating trapped air bubbles in complex catheter geometries.

A specialized infusion and sensing catheter delivers controlled flow to assess microvascular function during invasive procedures.

Removable volume indicator clips onto syringe body to display precise fluid measurements via window portion and inflation indicia.

A flexible catheter creates an expanded chamber to position endoscopic instruments laterally for precise tissue access.

A segmented balloon catheter design applies localized medicine coatings to specific regions, preventing structural cracks during deflation.

Disposable impermeable film isolates inner tube from bodily fluids, preventing biofilm accumulation and encrustation that causes catheter occlusion.

A double-threaded guidance wire locks a vertebral augmentation balloon to maintain axial length and stiffness during inflation cycles.

Acoustic radiation force impulse imaging detects tissue displacement via mechanical impulses, distinguishing durable ablation lesions from incomplete lines.

Segmented dual catheter kit reduces equipment complexity for emergency arterial obstruction treatment by enabling flexible stenting and clot removal.

A catheter tube uses a segmented polyamide structure to maintain interlayer bonding strength while ensuring visibility.

Periodic magnetic field operation reduces caloric value and voltage consumption while suppressing external leakage interference.

Rotating member converts axial rotation into linear pulling force, eliminating protruding handles that compromise operational safety in medical devices.

A balloon catheter integrates an irrigation tip with radial openings to deliver fluid directly into the sinus cavity during dilation procedures.

Axially elongating balloon resists removal without radial expansion, preventing urethral trauma during extraction.

A balloon sheath system manages fluid pressure and suction through dedicated passages for controlled inflation.

A catheter with a flow limiting element intermittently occludes the superior vena cava to reduce ventricular overload.
