Balloon Catheter TRIZ Cases
- Catheter Inflation Tube for Intravascular Lithotripsy
A collapsible inflation tube adjusts its cross-sectional area to guide fluid flow into a lithotripsy balloon.
- Flexible Multi-Lumen Brachytherapy Catheter with Keyed Stylet
Segmented lumens and a removable stylet resolve the trade-off between radiation versatility and catheter rigidity, reducing patient discomfort.
- Expandable Catheter Distal Cap for Disc Space Evaluation
A mandrel moves the distal cap of an expandable catheter to evaluate disc space volume after discectomy.
- Hemostatic Catheter Balloon Pressure for Prostatic Cavity Bleeding
Inflatable balloon exerts controlled pressure on the prostatic cavity to occlude bleeding vessels within a urethral catheter system.
