Occulders TRIZ Cases
- Embolization Device Segmentation for Anchoring and Vessel Occlusion
Distinct anchoring and packing sections improve stability and complete occlusion, including in high-flow vascular sites.
- Expandable Medical Device Support Member for Catheter Pushability
Braided support structures add column strength for controlled catheter delivery while preserving expandable-device compliance.
- Spiral-Strut Occlusive Devices for Wide-Neck Aneurysm Treatment
Spiral struts retain coils across wide aneurysm necks while limiting vessel protrusion.
- 3D Vaso-Occlusive Device Structure for Anchoring and Occlusion
Non-parallel loops, pyramidal sections, and helical anchors help prevent migration while extending occlusion in blood vessels.
- Degradable Occluder Locking Ring for Stable Occlusion
This case shows how a degradable occluder uses a deformable locking ring to prevent detachment while supporting endothelialization.
- Bioabsorbable Left Atrial Appendage Closure With Porous Endothelialization
A shape-memory closure uses a porous, tissue-promoting membrane to retain thrombi, support endothelialization, and reduce lasting foreign matter.
- Left Atrial Appendage Closure Framework for Adaptive Sealing
Segmented struts expand from a delivery sheath to conform to atrial appendage geometry and support secure thrombus-blocking closure.
- Vaso-Occlusive Implants With Friction Elements to Prevent Catheter Binding
A pushable coil and friction element guide expandable braids through catheters, supporting retrieval and larger-aneurysm filling.
- Braided Occlusion Device with Curved Loop Strands for Catheter Delivery
This case uses independently flexible curved loop strands to shrink the collapsed profile while preserving deployed stability and occlusion.
- Embolic Coil Connector With Stretch-Resistant Fiber Detachment
A proximal coil connector and fiber limit separation and premature release.
- Vascular Implant Delivery With Localized Thermal Tether Detachment
A catheter-contained heating element severs the tether locally, improving placement while limiting tissue damage and embolic particles.
- Occluder Pushing Device Locking Mechanism for Accurate Release
A translating and rotating traction element locks against the pushing tube to prevent premature release and improve deployment accuracy.
- Magnetic Anastomosis Segments for Polygonal Deployment and Force Control
Segmented magnetic devices shift from linear delivery to polygonal deployment, controlling attraction for reliable tissue compression.
- Vaso-Occlusive Coil Composite Structure for Anchoring and Shape Retention
A braided vaso-occlusive coil uses composite metallic layers and intra-device junctions to balance filling, anchoring, and strength.
- Low-Radial-Force Vascular Occlusion Sleeve for Vessel Protection
A flexible sleeve uses limited radial force and transmitted blood pressure to seal vessels while reducing wall damage and restenosis risk.
- LAA Balloon Occlusion Structure for Stable, Low-Trauma Sealing
This case uses an inflatable occlusive structure, proximal barrier, and dual ports for LAA sealing despite pulsation, without barbs.
- Flexible-Joint Implant Delivery Systems for Tortuous Anatomy
A segmented implant delivery system uses flexible joints to absorb bending forces and support reliable detachment in tortuous anatomies.
- Multi-Sharpness Soft Tissue Anchors for Left Atrial Appendage Occlusion
Rounded and sharpened anchor branches help occlude the left atrial appendage while supporting tissue penetration and retrieval.
