A sterile component of a hand-held cryosurgery system intended to be attached to the system handpiece to deliver liquid refrigerant (cryogen) [e.g., liquid nitrogen (LN2), nitrous oxide (N2O), carbon dioxide (CO2)] to skin/subcutaneous tissues for cryotherapy applications (e.g., surgical ablation, cosmetic, analgesic). It is typically a closed-end needle intended to deliver focused cooling to the therapy site without destroying healthy tissues. This is a single-use device.
