Excision Instruments TRIZ Cases
- Stentriever Membrane Aspiration Clot Retention
Membrane-directed aspiration creates negative pressure to secure friable thrombi without excessive radial force, preventing vessel wall damage.
- Occlusion Crossing Device With Rotating OCT Sensor
Rotating distal tip with OCT sensor provides real-time vessel imaging to navigate occlusions safely without damaging artery walls.
- Tissue Resecting Instruments with Auxiliary Vacuum
Segmented vacuum systems resolve contradictions between suction capability and device complexity in uterine resection.
- Atherectomy Catheter Cup-Shaped Cutter Particle Redirection
Cup-shaped surface and raised elements redirect tangential particles into the collection chamber, resolving dispersion issues during atherectomy.
- Expandable Tip Atherectomy Catheter for Tissue Storage and Expulsion
A catheter with an expandable distal tip retains cut tissue in a closed position and opens to release deposits.
- Tissue-removing Catheter with Adaptive Motor Control
A tissue-removing catheter adjusts rotational speed via a motor control circuit linked to an advancement sensor.
- Distal Release Retrieval Assembly for Minimally Invasive Stone Extraction
A distal release retrieval assembly enables controlled entrapment and extraction of stone fragments within anatomical lumens.
