Abstract
Abstract A cooling system is provided for organs during transplant surgery. A disposable receptacle (10) has a sterilizable interior and is formed of a material that is sufficiently rigid to maintain its shape normally without collapsing but sufficiently flexible to be squeezable manually. A disposable flexible container (16) is located inside the receptacle. The flexible container (16) contains a liquid solution that is adapted to be chilled in a freezer. The flexible container (16) and its contents are sterilizable and useful for providing cooling for organs during surgical transplants. The disposable receptacle (10) has a peelable lid (14) that is sealed to a tray portion (12) to enable the sterilizable container (16) to be aseptically removed from the receptacle (10).

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
136 words
A cooling system for organs, which comprises: a disposable receptacle having a sterilizable interior and formed of a material that is sufficiently rigid to maintain its shape normally without collapsing but sufficiently flexible to be squeezable manually whereby the person squeezing the receptacle can generally determine a condition of the receptacle's contents; a disposable flexible container located inside the receptacle, said flexible container containing a liquid solution that is adapted to be chilled in a freezer, said flexible container and its contents being sterilizable and useful for providing cooling for organs during surgery; said disposable receptacle including means for enabling said sterilizable container to be aseptically removed from said receptacle when sterile and remain in sterile condition; and a tray portion with said enabling means comprising a cover that is manually removable from said tray portion.
Claim 2
Dependent Claim
136 words

A cooling system as described in claim 1, said flexible container comprising a bag formed of a flexible plastic material.
Claim 8
Dependent Claim
14 words
A cooling system as described in claim 1, said liquid solution comprising saline solution.
Claim 9
Dependent Claim
24 words
a cooling system as described in claim 1, said receptacle having a volume that is slightly greater than the volume of the flexible container.
Claim 10
Independent Claim
126 words
A system for cooling organs comprising the steps of: providing a closed disposable receptacle having a sterilizable interior and formed of a material that is sufficiently rigid to maintain its shape normally without collapsing but sufficiently flexible to be squeezable manually whereby the person squeezing the receptacle can generally determine a condition of the receptacle's contents, said receptacle having therein a closed disposable flexible container that contains a liquid solution; sterilizing the disposable receptacle and the disposable flexible container while the container is within the closed receptacle; cooling the combined receptacle and container in a freezer; thereafter removing the cooled receptacle and container from the freezer; aseptically removing the cooled container from the receptacle for using the cooled liquid as a cooling medium during surgery; and
Claim 11
Independent Claim
