Case studies:
- Uniform insertion depth: 14 cryoprobes, each having an active length of 25 mm
- Variable insertion depth: 20 cryoprobes, each having an active length of 15 mm
- Variable insertion depth: 14 cryoprobes, each having an active length of 25 mm
- Variable insertion depth: 14 cryoprobes, each having an active length of 35 mm
- Pullback procedure: 14 cryoprobes in Cycle I and 7 cryoprobes in Cycle II, each having an active length of 25 mm (uniform insertion depth at each stage; the -22°C isotherm from the end of Cycle I is held stationary during the simulation of Cycle II)
