Abstract
Abstract A thermal packaging unit for a biocompatible implant. The thermal packaging unit includes a first compartment for storing the biocompatible implant. In addition, the thermal packaging unit further includes a second compartment which is operable to contain a chemical composition which is able to heat the biocompatible implant by means of an exothermic reaction.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A method for heating a preformed biocompatible implant comprising the steps of: disposing said preformed biocompatible implant in a thermal packaging unit, said thermal packaging unit including (a) means for receiving said biocompatible implant, and (b) means for delivering thermal energy to said biocompatible implant upon activation of said thermal packaging unit; activating said thermal packaging unit so as to cause said thermal energy to be delivered to said biocompatible implant; allowing said biocompatible implant to be heated to a temperature where said biocompatible implant becomes deformable; and removing said biocompatible implant from said thermal packaging unit after said biocompatible implant becomes deformable.
Claim 2
Independent Claim
103 words
A method for heating a preformed biocompatible implant comprising the steps of: disposing said preformed biocompatible implant in a thermal packaging unit, said thermal packaging unit including (a) means for receiving said biocompatible implant, and (b) means for delivering thermal energy to said biocompatible implant upon activation of said thermal packaging unit; activating said thermal packaging unit so as to cause said thermal energy to be delivered to said biocompatible implant; allowing said biocompatible implant to be heated to a temperature where said biocompatible implant becomes deformable; and removing said biocompatible implant from said thermal packaging unit after said biocompatible implant becomes deformable.
Claim 3
Dependent Claim
34 words
The method according to claim 1, further comprising the additional step of reinserting said biocompatible implant into said thermal packaging unit so as to cause thermal energy to be delivered to said biocompatible implant.
Claim 4
Dependent Claim
43 words
The method according to claim 1, wherein said thermal packaging unit further includes a first compartment containing a first chemical composition, said step of activating said thermal packaging unit further including the step of introducing a second chemical composition into said first compartment.
Claim 5
Dependent Claim
21 words
The method according to claim 3, wherein said first chemical composition includes calcium chloride and said second chemical composition includes water.
Claim 6
Dependent Claim
53 words
The method according to claim 3, wherein said second chemical composition is disposed within a second compartment, said step of introducing said second chemical composition into said first compartment further includes the step of rupturing said second compartment so as to cause said second chemical composition to react with said first chemical composition.
Claim 7
Dependent Claim
47 words
The method according to claim 3, wherein the step of introducing said second chemical composition into said first compartment includes the step of injecting said second chemical composition into said first compartment so as to cause said second chemical composition to react with said first chemical composition.
Claim 8
Dependent Claim
33 words
The method according to claim 1, wherein said thermal packaging unit further comprises an activation disk, said step of activating said thermal packaging unit further including the step of deforming said activation disk.
Claim 9
Dependent Claim
43 words
The method according to claim 1, further comprising the additional step of maintaining the sterility of said biocompatible implant from when said biocompatible implant is disposed within said thermal packaging unit until when said biocompatible implant is removed from said thermal packaging unit.
