Cryoablation is a process that uses extreme cold (cryo) to destroy or damage tissue (ablation). Cryoablation is used in a variety of clinical applications using hollow needles (cryoprobes) through which cooled, thermally conductive, fluids are circulated. Cryoprobes are inserted into or placed adjacent to tissue which is determined to be diseased in such a way that ablation will provide correction yielding benefit to the patient.
FedEx defines oversized packages as follows (current as of August 2005). 1  A package weighing less than 30 lbs. and measuring more than 84 inches and equal to or less than 108 inches in combined length and girth will be classified by FedEx Ground as an Oversize 1 (OS1) package.
Another benefit to UPS and FedEx is that they can ship packages that weigh up to 150 lbs. The weight limit for USPS is 70 lbs. These are the exceptions, however. By and large USPS rates are more competitive.
