Disposable sheath with replaceable console probes for cryosurgery

A method of performing a cryosurgical procedure, comprising:

• providing a disposable sheath having a proximal insertion end and a distal tip end;
• inserting a cryoprobe into a sheath opening at the proximal insertion end;
• supplying a refrigerant to the cryoprobe to freeze tissue at the distal tip end;
• stopping the flow of refrigerant through the cryoprobe;
• powering at least one heating wire on the sheath body to heat the distal tip end;
• thawing frozen tissue with the heated distal tip end;
• removing the disposable sheath from the cryoprobe;
• and
• discarding the disposable sheath.

• supplying a refrigerant to the cryoprobe to freeze tissue at the distal tip end;
• and
• insulating a proximal portion of the cryoprobe to define a freeze portion at a cryoprobe tip, wherein insulating the proximal portion includes maintaining a vacuum within an insulation spaced defined at the proximal portion of the cryoprobe.
