Patent ID: 7575131

Claim:
A delivery system comprising: a first assembly having a proximal end region, a distal end region, a first chamber capable of containing therein a first component, a second chamber capable of containing therein a second component, a first channel extending from the first chamber to the distal end region of the first assembly, a second channel extending from the second chamber to the distal end region of the first assembly, and a first coupling element at the distal end region thereof; a second assembly having a proximal end region, a distal end region, a third chamber capable of containing therein a third component, a fourth chamber capable of containing therein a fourth component, a third channel extending from the third chamber to the distal end region of the second assembly, a fourth channel extending from the fourth chamber to the distal end region of the second assembly, and a second coupling element at the distal end region thereof, wherein the first and second coupling elements are engageable so as to movably couple the first and second assemblies, and wherein, when the first and second assemblies are so coupled, the second assembly is rotatable relative to the first assembly to a first position wherein the first and third channels are not in communication with one another and are not axially aligned, and wherein the second and fourth channels are not in communication with one another and are not axially aligned, and to a second position wherein the first and third channels are in communication with one another and are not axially aligned so as to form a conduit between the first and third chambers, and the second and fourth channels are in communication with one another and are not axially aligned so as to form a conduit between the second and fourth chambers.
