Dilators TRIZ Cases

Segmented multi-strand coils in a dual-layer design increase mass per length without raising stiffness, reducing procedure time and preventing breakage.

Expandable vascular introducer sheath reduces frictional resistance and insertion force, eliminating repeated vessel trauma from multiple device exchanges.

Segmented pusher and releasing members with an intermediary filament prevent junction movement and recoil during mechanical detachment of embolic coils.

Mechanical basket forceps dilate the urethra to capture embedded stones, eliminating chemical toxicity risks while preserving tissue integrity.

A helical dilation device expands radially to maintain urethral patency, preventing recompression from enlarged prostate tissue.

A rheolytic catheter uses a self-inflating distal balloon to center the device and isolate blood flow for effective thrombus removal.

Radial catheter expulsion improves polymer adherence to lumen walls, preventing migration and recanalization during temporary occlusion.

Proximal fiber bundle concentration increases column strength to prevent buckling during embolic coil deployment.

A braided medical implant uses a segmented stem to connect an expanded diameter portion to a tubular member for flexible delivery.

Segmented bundle of preformed shape memory wires delivers rapid radial expansion, reducing deployment time and dislodgment risk in vascular procedures.

Single-layer polyamide 6.12 balloons achieve burst pressure above 20 bar while reducing wall thickness to improve catheter deliverability.

A tapered dilation device widens occluded channels over a guide-wire, easing balloon passage through calcified stenosis.

Elastic uterine and cervical supports prevent adhesion by enabling secretion discharge through concave valve bodies.

Guide members constrain a detachable link to prevent premature coil detachment and jamming during endovascular delivery.

Merging multiple coils into one integrated body reduces procedural time while maintaining reliable vessel occlusion through radial expansion.

An enhancing coil protects the detachment zone from buckling during vascular navigation while enabling reliable electrolytic device release.
