Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
55 words
A kit of parts comprising: a first member which is an embolic composition comprising a biocompatible polymer having an equilibrium water content of less than about 15% water, a biocompatible solvent and a contrast agent; and a second member which is a needle selected from the group consisting of a puncture needle and spinal needle.
Claim 2
Dependent Claim
55 words
A kit of parts comprising: a first member which is an embolic composition comprising a biocompatible polymer having an equilibrium water content of less than about 15% water, a biocompatible solvent and a contrast agent; and a second member which is a needle selected from the group consisting of a puncture needle and spinal needle.
Claim 3
Dependent Claim
49 words
