Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
122 words
A tissue bondable cystostomy tube comprising: a. a subcutaneous hollow cylinder coated on its exterior surface with a material suitable for bonding with biological tissue, said subcutaneous hollow cylinder having an upper end and a lower end; b. a planar disc-like base coated on its exterior surface with a material suitable for bonding with biological tissue, said disc-like base extending radially outward from the lower end of said subcutaneous hollow cylinder; and c. a transcutaneous hollow cylinder coated on its exterior surface with a material suitable for bonding with biological tissue, said transcutaneous hollow cylinder having a lower end and an upper end, the lower end of said transcutaneous hollow cylinder slidably received into the upper end of said subcutaneous hollow cylinder.
Claim 2
Dependent Claim
122 words
