Catheter TRIZ Cases

A compact robotic driving assembly uses multi-plane wheel pairs to grip and move elongate surgical tools with precise traction.

An elastic member secures the catheter hub in a U-shaped receptacle, while a cushioning layer prevents skin irritation from rigid device edges.

A heat exchanger unit cools sterile liquid in a first chamber via thermal conductivity with a cooler in a second chamber.

A steerable surgical snare maintains a constant loop length during deflection to capture foreign bodies within body lumens.

Mesh reinforcement gaps allow thermoplastic resin to flow between catheter layers, suppressing interface disorders and maintaining pushability under stress.

Integrating wire delivery and snare capture into one catheter reduces procedural time and complexity during TAVR leaflet laceration.

A two-piece catheter securement system captures medical tubing via a stud-and-socket mechanism, preventing lateral movement that causes vein irritation.

Nested roller modules transmit precise translation and rotation to flexible catheters, preventing buckling during body insertion.

Dual balloon catheter forms a thermal insulation cavity between concentric balloons, preventing unintended peripheral tissue freezing during cryoablation.

Segmented carbon nanotube membranes on a multi-focal catheter measure real-time pressure gradients, eliminating fragile guidewires and pullback studies.

Direct optoacoustic measurement of fetal cerebral oxygenation replaces indirect heart rate monitoring, reducing unnecessary cesarean sections.

A sensor inserter striker assembly engages a lock beam to transition into a disposal state that physically prevents reuse.

A hermetically sealed implant housing uses thin film membranes to maximize internal volume for antenna placement.

Analyte monitoring system calculates mean and standard deviation from multiple data points to model probability distributions for glucose projections.

Foldable securement arms cradle the catheter while a transparent cover protects the site from infection risks caused by traditional tape.

Integrated tubular structure eliminates complex casing assembly to resolve production errors and improve implantation comfort.

Vapor pretreatment induces nucleation sites that control paclitaxel crystal size during annealing, ensuring predictable tissue residence time.
