Excision Instruments TRIZ Cases
- Segmented Bipolar RF Electrode for Hemostasis in Tissue Resection
Segmented bipolar electrodes apply radio frequency energy to necrose tissue along a resection plane, reducing bleeding during morcellation.
- Atraumatic Retrieval Basket With Retainer For Tissue-Safe Calculus Extraction
Joining retrieval basket leg intermediate portions via a retainer creates an atraumatic distal end that prevents tissue trauma during calculus extraction.
- Multiple Loop Snare Device for Vascular Intervention
A snare device with multiple loops of varying sizes and shapes deploys through a single outer sheath.
- Catheter Cutting Sheath for TAVR Valve Leaflet Resection
A catheter cutting sheath resects damaged aortic valve leaflets via laser ablation to prepare the implantation site.
- Orbital Atherectomy Abrasive Element Asymmetry
Asymmetric flat-sided abrasive element generates larger lumens in small apertures by reducing power requirements through orbital cutting paths.
- Vascular Treatment Wire Sheath Coupling Mechanism
A vascular treatment wire sheath coupling mechanism engages a handle to expose the distal tip, preventing accidental vessel damage during insertion.
- Flexible Distal Tip Tissue-Removing Catheter
Segmenting the rigid cutter from a flexible distal tip resolves the contradiction between effective tissue removal and safe navigation through narrow lumens.
- Spine Cutter with Parabolic Grooves for Gentle Cervical Milling
Parabolic grooves create tapered teeth on a milling cutter, reducing tissue damage during cervical spine surgery.
- Catheter Drive Assembly for Simultaneous Rotation and Reciprocation
A catheter drive assembly imparts simultaneous rotation and reciprocation to a tissue-removing element via a specialized rotor mechanism.
