Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
A ureterostomy device comprising: a passageway having an anchor means, both of which are formed from a material selected from the group consisting of (1) pyrolytic carbon disposed on a graphite substrate and (2) vitreous carbon, for attachment to an opened vessel; said anchor means for establishing a biological anchor; and said passageway being further defined as having a substantially rigid inlet section initiated with a passageway inlet and a substantially rigid outlet section terminated with a passageway outlet and in communication with said inlet section wherein the axial centerline passing through the center of said passageway inlet is inclined with respect to the axial centerline passing through the center of said passageway outlet from between about 45 degrees and about 75 degrees.
