Balloon catheter inflation & deflation
Simulates the full cycle of a balloon (inflation to nominal diameter, deflation to the withdrawal profile). Automatic Hagen-Poiseuille / Darcy-Weisbach switching for the inflation lumen, P-V model calibrated on the manufacturer datasheet. Feasibility verdict hand syringe vs indeflator.
Transient pressure-volume model for balloon catheter inflation and deflation through the inflation lumen.
Combines Hagen-Poiseuille (laminar lumen flow) and Darcy-Weisbach (friction loss) with balloon compliance to predict full pressure-time and volume-time profiles.
Darcy-Weisbach — friction loss in pipe flow.
Ideal gas equation (PV = nRT) for compressed air inflation media.
Balloon compliance — pressure-volume relationship for compliant vs non-compliant balloons.

Want to discuss your project?
Inflation/deflation predictions are first-order. They assume rigid catheter shaft, ideal gas behavior for compressed air, and constant temperature — validate against benchtop measurements for clinical timing.
Inflation timing, balloon material, indeflator sizing? Our catheter engineers can help with custom balloon design — PET, Nylon, Pebax — from prototype to clinical pilot.
