CRYO-S Painless for cryoanalgesia in pain management

Steps to a painless future

QiTec is pleased to partner with BVM Medical to bring the Metrum Cryoflex’s Cryo S Painless to the Interventional Pain community in the UK & Ireland

Cryoanalgesia – release from chronic pain

With over 30 years of experience, CRYO-S ® PAINLESS is a state-of-the-art cryosurgical device manufactured by METRUM CRYOFLEX is the next generation of apparatus used by many experts in the field since 1992.

CRYO-S ® Painless is controlled by a microprocessor and all the parameters are displayed and monitored on a LCD screen. Cryoprobe temperature, cylinder pressure, gas flow inside of cryobrobe and procedure time are displayed during freezing.

CRYO-S ® Painless is the most technologically advanced device for cryoneurolisis. For patients with chronic pain at the level of over 5 in visual analogue scale (VAS).

The advantages of Cryoanalgesia

  • No more “pain killers”
  • Immediate pain reduction
  • No neuroma formation – no risk of secondary pain
  • High efficiency: pain reduction from 6 months to 2 years
  • Can be repeated – nerve grows back
  • Simple diagnostics: fluoroscopy or echography
  • No scar tissue formation
  • Suitable for patients with pacemakers and stimulators
  • No risk of vessel proliferation and obliteration
  • Fast return to normal activity – no hospitalization

Clinical application

  • Knee pain prior or secondary to infrapatellar branch of the saphenous nerve, anterior femoral cutaneous nerve, genicular nerve after knee arthroplasty or total knee replacement
  • Various types of peripheral neuropathy
  • Diabetic neuropathy
  • Low back pain and lower extremity pain secondary to lumbar facet joint pathology, pseudosciatica
  • Phantom pain
  • Morton’s neuroma, heel pain
  • Sacroiliac joint pain, cluneal neuralgia, obturator neuritis
  • Chest wall pain with multiple conditions including post-thoracotomy neuromas, persistent pain after rib fractures and post herpetic neuralgia in thoracic distribution
  • Abdominal and pelvic pain secondary to ilioinguinal, iliohypogastric, genitofemoral, subgastric neuralgia, pudendal neuralgia
  • Craniofacial pain secondary to trigeminal neuralgia, posterior auricular neuralgia, and glossopharyngeal neuralgia
  • Upper extremity pain secondary to suprascapular neuritis and other conditions of peripheral neuritis

– Impulse width setting: 0.1, 0.2, 0.5, 1.0, 2.0-5.0 ms

Functional modes of unique cryoprobe preparing system:
– Standard: cryoprobe is automatically purged before each procedure for several seconds and then a few seconds of testing freezing is performed. In this mode cryoprobe is tested and prepared according to parameters programmed on attached microchip. When such preparation is finished cryoprobe is ready for freezing.
– Service: it starts automatically when decreased flow rate in cryoprobe or cryoprobe blockage is noticed. It can be performed also during the procedure. Service mode is diagnosing and solving problems caused by previous improper use of the cryoprobe.

• Dimensions: 39/42/19 cm
• Weight: 11 kg

Indications for cryoanalgesia

Cryoanalgesia, is a specialized technique for providing long-term pain relief in interventional pain management settings. Cryoanalgesia bases on temporary disruption of neural and motor functions of some parts of the nerve system using extreme cold. Cryolesion is gaining acceptance as an innovative method in pain relief. It bases on the process of analgesia, during which ice crystals created by a cryosurgery device destroys the elements of the nerve tissue carrying pain information. Cryoablation does not damage nerve structures permanently that is why nerve tissues can regenerate slowly with no risk of post-procedural neuritis. The method is safe and minimally invasive, recommended especially when conservative means proved to be ineffective.

Indications for cryoanalgesia:
• Acute postoperative pain from thoracotomy
• Facial pain syndromes (supra-infra orbital,occipital,mental)
• Suprascapular, Ilio-inguinal and other specific neuralgias
• Facet syndrome – cervical, thoracic and lumbosacral
• Coccydynia
• Perineal neuropathies
• Phantom Limb
• Trigger points
• Painful neuromas
• Tennis elbow syndrome and golfer’s elbow syndrome
• Painful shoulder syndrome

Advantages of cryoanalgesia:
• Microinvasive procedure, reversible effect
• High efficiency: pain reduction for 6 months to 2 years
• Simple diagnostics: fluoroscopy or echography
• Subcutaneous procedure, microinvasive under local anesthesia
• Fast return to normal activities – no hospitalization
• Can be repeated
• Low cost
• Whole range of reusable contact probes of various shapes and sizes
• Painless
• Small incisions, usually leave only few little scars instead of one larger scar
• Less tissue dissection
• Less damage to surrounding muscles
• Minimal blood loss and fast healing.
