Blood Vessels TRIZ Cases
- Branch-Tube Anastomosis Valve for Bloodless Vascular Connection
A branch tube, valve, and ligature enable bloodless vascular anastomosis without prolonged clamping, reducing flow interruption risks.
- Sutureless Anastomosis Connector With Active Tines for Secure Coupling
Mechanically active tines use shape memory or elastic actuation to secure tissue-to-conduit coupling without sutures, reducing procedure time.
- Multilayer Vascular Graft Structure for Small-Vessel Patency
Porous multilayer grafts with macropores and biofragmentable layers support tissue ingrowth to improve small-vessel patency and remodeling.
- Porous Membrane Lymph Implant for Post-Dissection Fluid Conduction
A porous membrane stent graft restores lymph flow after node dissection, helping prevent lymphoedema and seroma while enabling drug delivery.
- Intravascular Emboli Filter With Aortic Arch Stabilizers
A tethered filter with upper and lower stabilizers captures emboli larger than 50 µm while anchoring in the aortic arch to protect secondary arteries.
