CRYO-S® Painless is a high-tech device

for cryoneurolysis. An innovative method of chronic pain treatment


is a therapeutic method based on the temporary interruption of sensory functions in selected structures of the nervous system by application of low temperature. Cryoanalgesia is becoming increasingly popular as an innovative method for relieving pain. This method uses the process of analgesia, during which the ice crystals created by the cryosurgical system destroy the elements of the nerve tissue carring pain information. Cryoanalgesia does not damage nerve structures permanently that is why nerve tissue can regenerate slowly without the risk of post-procedure neuroma. Cryoanalgesia is a minimally invasive and safe procedure recommended mainly in cases where traditional methods have been proved as ineffective.

Mechanism of cryoanalgesia

Large myelin sensory or mixed nerves are responsible for conduction of pain impulses from the periphery to the center. Cryoanalgesia is indicated for patients with chronic pain, the intensity of which exceeds the level of "5" on the visual analog scale (VAS).

During interventional cryoanalgesia, an ice ball destroys the axon of the neuron distally and slightly closer to the site of injury with the appearance of Valerian cell degeneration there. The axon and its myelin sheath are damaged, but Schwann cells, endoneurium, perineurium, and epineurium remain intact. Thus, the pain disappears

The rate of outgrowth nerve fibre is about 1 mm per day, so that the final recovery of nerve conduction depends on the quality of freezing. Even if the peripheral nerve structures recover after some weeks, the functionality of the sensory nerve still remains blocked. In mixed nerves, mobility functions recover much faster than in sensory. Cryoanalgesia is also a recommended and safe method for the treatment of pain resulting from mixed nerve damage (eg, «scapular periarthritis»).

Complete sensory nerve recovery, including its functionatily, takes place within 6-12 months after the Cryoanalgesia procedure. During this period, the patient does not feel pain or pain is significantly reduced.
