Excision Instruments TRIZ Cases
- Expandable Rotating Cutting Device for Calcified Stenosis
An expandable cutting part on a rotating tubular shaft adapts to vessel diameter while limiting contact with normal blood vessels.
- Bronchoscopic Airway Wall Abrasion for Mucus Reduction
Controlled airway-wall abrasion targets mucus-producing goblet cells while preserving deeper tissue and reducing mucus production.
- Airway Wall Abrasion for Selective Mucus Cell Removal
Mechanical abrasion selectively removes mucus-producing airway cells at controlled depth to reduce mucus, inflammation, and obstruction.
- Thrombectomy Control Assemblies for Variable Vessel Geometries
Biasing and brake mechanisms control an expandable cage’s radial force to harvest thrombus across large, tapered, and branched vessels.
- Multi-Element Atherectomy Cutter for Total Occlusion Debulking
Multiple cutting elements address extended total occlusions, improving plaque debulking while reducing arterial wall injury.
- Tissue-Removing Catheter With Coupled Inner Liner for Guidewire Isolation
An advancer-coupled inner liner transfers axial forces to the tissue-removing element while isolating the guidewire from drive-coil rotation.
- Bidirectional Thrombus-Breaking Device With Periodic Rotation Stops
Alternating shaft rotation with stops creates shear stress to break attached thrombi and floating emboli while supporting aspiration.
- Cervical Spine Endplate Shaver for Precise Bone Preparation
Hand-rotated blades remove cervical endplate bone with controlled decortication, helping position ceramic cages and reduce subsidence risk.
- Sensor-Guided Suction Catheter for Controlled Clot Removal
Integrated catheter sensors identify clot contact in real time, allowing suction and maceration to adjust while limiting blood loss.
- Rotational Atherectomy Burr Arrays for Small-Vessel Navigation
Multiple abrasive elements and a flexible torque-transmitting shaft help treat stenotic lesions in small, tortuous vessels through orbital abrasion.
