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
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 3
Dependent Claim 21 words
The cystostomy tube of claim 1 further comprising a removable cap affixed to the upper end of said transcutaneous hollow cylinder.
Claim 4
Dependent Claim 19 words
The cystostomy tube of claim 1 wherein the material suitable for bonding with biological tissue is a polytetrafluoroethylene polymer.
Claim 5
Dependent Claim 19 words
The cystostomy tube of claim 2 wherein said cap further comprises an antimicrobial filter internally mounted in said cap.
Claim 6
Dependent Claim 42 words
The cystostomy tube of claim 1 further comprising a stabilizing slipover disc sleeve coated on its exterior surface with a material suitable for bonding with biological tissue, said slipover disc sleeve centrally located on the exterior surface of said subcutaneous hollow cylinder.
Claim 7
Dependent Claim 51 words
The cystostomy tube of claim 1 wherein the lower end of said transcutaneous hollow cylinder has an outer diameter sized to fit snugly within said subcutaneous hollow cylinder and the upper end of said transcutaneous hollow cylinder has an outer diameter equal to the outer diameter of said subcutaneous hollow cylinder.
Claim 8
Dependent Claim 19 words
The cystostomy tube of claim 1 wherein said planar disc-like base is integrally formed with said subcutaneous hollow cylinder.
Claim 9
Dependent Claim 162 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 integrally formed with said subcutaneous hollow cylinder and 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; d. a stabilizing slipover disc sleeve centrally located on the exterior surface of said subcutaneous hollow cylinder; and e. a removable cap affixed to the upper end of said transcutaneous hollow cylinder.
Claim 10
Dependent Claim 162 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 integrally formed with said subcutaneous hollow cylinder and 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; d. a stabilizing slipover disc sleeve centrally located on the exterior surface of said subcutaneous hollow cylinder; and e. a removable cap affixed to the upper end of said transcutaneous hollow cylinder.
Claim 11
Dependent Claim 51 words
The cystostomy tube of claim 8 wherein the lower end of said transcutaneous hollow cylinder has an outer diameter sized to fit snugly within said subcutaneous hollow cylinder and the upper end of said transcutaneous hollow cylinder has an outer diameter equal to the outer diameter of said subcutaneous hollow cylinder.
