Abstract
Abstract A method and apparatus for packaging, mixing and delivering bone cement formed from at least a first component and a second component includes a first container, a second container and a mixing member. The first container is operable to be selectively opened and closed and further operable to be sealably prepackaged with the first component of the bone cement. The second container is operable to deliver the second component of the bone cement to the first container. The mixing member forms a part of the first container and is operable to mix the first and second components of the bone cement substantially within only the first container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
An apparatus for packaging, mixing and delivering bone cement formed from at least a first component and a second component, said apparatus comprising: a first flexible bag operable to be selectively opened and closed, said first flexible bag having a flexible and resilient rib and being sealably prepackaged with the first component of the bone cement; a second container operable to deliver the second component of the bone cement to said first bag; and a closure mechanism coupled to said first flexible bag by way of engaging an annular groove formed in a disk coupled to said closure mechanism with said flexible and resilient rib, said closure mechanism operable to selectively open and close said first flexible bag wherein upon opening said first flexible bag with said closure mechanism, said second container delivers the second component of the bone cement to said first bag, and wherein upon closing said first flexible bag with said closure mechanism, said first flexible bag is operable to mix the first and second components of the bone cement substantially within only said first flexible bag upon massaging said first flexible bag.
Claim 2
Independent Claim
186 words
An apparatus for packaging, mixing and delivering bone cement formed from at least a first component and a second component, said apparatus comprising: a first flexible bag operable to be selectively opened and closed, said first flexible bag having a flexible and resilient rib and being sealably prepackaged with the first component of the bone cement; a second container operable to deliver the second component of the bone cement to said first bag; and a closure mechanism coupled to said first flexible bag by way of engaging an annular groove formed in a disk coupled to said closure mechanism with said flexible and resilient rib, said closure mechanism operable to selectively open and close said first flexible bag wherein upon opening said first flexible bag with said closure mechanism, said second container delivers the second component of the bone cement to said first bag, and wherein upon closing said first flexible bag with said closure mechanism, said first flexible bag is operable to mix the first and second components of the bone cement substantially within only said first flexible bag upon massaging said first flexible bag.
Claim 3
Dependent Claim

Claim 5
Independent Claim
138 words
A method for packaging, mixing and delivering bone cement formed from at least a first component and a second component, said method comprising the steps of: providing a first container that is operable to be selectively opened and closed; prepackaging the first container with the first component of the bone cement disposed therein; coupling the first container to a valve body by engaging an annular groove formed in a disk coupled to the valve body with a flexible rib forming part of the first container; selectively opening the first container; delivering the second component of the bone cement from a second container to the first container; selectively closing the first container; and mixing the first and second components of the bone cement substantially within only the first container with a mixing member forming part of the first container.
Claim 6
