Occulders TRIZ Cases
- LAA Closure Device Anchoring via Pericardial Space
A left atrial appendage closure device anchors in the pericardial space to prevent migration.
- Self-Adaptive Embolic Coil with Shape-Memory Alloy
A self-adaptive embolic coil system uses a shape-memory alloy and gripper assembly to deploy, reconnect, and disconnect the device.
- Elastic Loop Wire Prevents Implant Detachment
An elastic loop wire secures an implant to a delivery system by applying tension to the pull wire.
- Galvanic Corrosion Detachment for Implantable Devices
Galvanic corrosion of the junction detaches the implant, eliminating vessel damage and thrombi caused by external energy sources.
- Photo-sensitive Liquid Embolic Material for Aneurysm Occlusion
A photo-sensitive liquid embolic material hardens in situ via light-controlled photopolymerization to fill irregular vascular cavities.
- Occlusive Implant Hub Dynamics for LAA Sealing
A shifting central hub within an expandable framework conforms to varying left atrial appendage geometries while maintaining constant height and radial force.
- Self-Expanding Vascular Occlusion Device with Loop Anchoring
Multi-loop self-expanding frame anchors in vessels to prevent migration during single-deployment occlusion.
- Self-Expanding Occlusion Device with Nested Collars
Nested collars and radial struts enable rapid occlusion, eliminating the time required for embolus formation in coil-based treatments.
- Left Atrial Appendage Occluder with One-Way Valve
One-way valve in bioprosthetic cover allows blood flow into the left atrial appendage for stretch obliteration, eliminating residual leaks.
- Planar Hub Occlusion Device for Left Atrial Appendage
A medical occlusion device features a planar hub component that minimizes protrusion into the left atrial chamber.
- Self-Expanding Vascular Occlusion Device with Hub Anchor
Segmented hub and cylindrical portions resist kickback forces while achieving effective single-deployment vessel blockage.
