Stents TRIZ Cases

Mechanical conditioning isolates NiTi defects in martensite zones, improving tubing fatigue strength while preserving superelastic behavior.

A planetary gear trigger assembly converts simple reciprocating motion into precise inner shaft movement for accurate stent deployment.

A clover-shaped retention structure and mesh holding section conform to wide-neck aneurysms and retain embolic coils for reliable occlusion.

Sequential tapered funnels and barrels uniformly crimp a heart valve prosthesis to sheath diameter for precise loading and minimally invasive delivery.

Short radial dies compress stents incrementally for catheter loading, cutting force, wear, compliance, and contamination risk.

Pre-cut break-off x-ray markers enable batch production, strong scaffold bonding, and passivated surfaces that limit corrosion risk.

Precisely laser-formed openings make stent-graft material selectively permeable, promoting tissue ingrowth while reducing endoleaks and migration.

An impermeable outer layer seals the dissection while a permeable inner layer promotes coagulation and tissue ingrowth to prevent endoleaks and migration.

A flexible sock pulls expanded prosthetic valves through a tapered lumen to crimp rigid designs with better force control and portability.

A tapered-channel container stores a transcatheter heart valve expanded, then crimps it during removal to limit handling damage before implantation.

Magnetic data written on implantable fabric lets prostheses store and reveal patient or procedural information without continuous power.
