WHY LUNG CRYO?

PULMONARY & THORACIC TUMORS

Offers an important alternative for poor surgical candidates. (4)
Provides palliative treatment for thoracic tumors. (5)

Benefits of PerCryo Treatment

HIGHLY VISIBLE UNDER IMAGE GUIDANCE

CT imaging produces a 40 Hounsfield unit drop in attenuation. (8)
CT allows for complete visual monitoring and verification of the ice ablation zone.

DECREASED PAIN DURING & POST PROCEDURE

Ice formation produces a natural pain anesthetic. (9)
Clinical studies have shown reduced narcotics during and post procedures. (9)

DOES NOT DESTROY COLLAGEN

Ice allows the natural tissue architecture to remain intact.
Treatments are possible near and around critical vessels and structures. (1)

ICE PROPAGATION IS PREDICTABLE & REPRODUCIBLE

Reproducible and predictable ice propagation provides enhanced control.
Consistent ice formation provides simple and accurate planning and monitoring.

MULTIPLE CRYOPROBES MAY BE USED SIMULTANEOUSLY

Multiple Cryoprobes used simultaneously can create a large ablation zone.
Multiple Cryoprobes allow treatment of multiple tumors concurrently.
