Claims
- 1. A tissue bondable cystostomy tube comprising:
- a. a deep implant cylinder comprising an upper portion and a lower portion terminating at a lower end point, the lower portion of said deep implant cylinder coated on its exterior surface with a porous biocompatible tissue bonding material;
- 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 point of said deep implant cylinder and said base having a substantially constant radial dimension; and
- c. a transcutaneous hollow cylinder having an open lower end and a flanged upper end, the lower end of said transcutaneous hollow cylinder slidably received into the upper portion of said deep implant cylinder and extending to the lower end point of said deep implant cylinder.
- 2. The cystostomy tube of claim 1 further comprising a removable cap and drainage tube assembly affixed to the upper end of said transcutaneous hollow cylinder.
- 3. The cystostomy tube of claim 2 wherein the porous biocompatible tissue bonding material is polyurethane.
- 4. The cystostomy tube of claim 2 wherein the porous biocompatible tissue bonding material is Dacron.RTM..
- 5. The cystostomy tube of claim 2 wherein the porous biocompatible tissue bonding material is a porous alloplastic material.
- 6. The cystostomy tube of claim 2 wherein the material suitable for bonding with biological tissue is a polytetrafluoroethylene polymer.
- 7. The cystostomy tube of claim 2 wherein said cap and drainage tube assembly comprises:
- a. a conically-shaped cap having a top surface and a bottom surface, said top surface having a larger diameter than said bottom surface, and said cap is sized to fit snugly within the upper end of said transcutaneous hollow cylinder;
- b. an external drainage tube attached to and extending outward from said cap; and
- c. an internal drainage tube extending downward from inside of said cap, said internal drainage tube being in fluid communication with said external drainage tube.
- 8. The cystostomy tube of claim 2 wherein said cap and drainage tube assembly is threadably affixed to the upper end of the transcutaneous hollow cylinder.
- 9. The cystostomy tube of claim 1 further comprising a stabilizing flange coated on its exterior surface with a material suitable for bonding with biological tissue and slidably mounted on the exterior surface of said deep implant cylinder.
- 10. The cystostomy tube of claim 1 wherein the transcutaneous hollow cylinder has an outer diameter sized to fit snugly within said deep implant cylinder.
- 11. The cystostomy tube of claim 1 wherein said planar disc-like base is integrally formed with said deep implant cylinder.
- 12. A tissue bonding cystostomy tube comprising:
- a. a deep implant cylinder, having an upper portion and a lower portion terminating at a lower end point, said deep implant cylinder coated on the lower portion of its exterior surface suitable for bonding with biological tissue;
- b. a planar disc-like base integrally formed with said deep implant 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 point of said deep implant cylinder and said base having a substantially constant radial dimension;
- c. a transcutaneous hollow cylinder having a lower end and a flanged upper end, the lower end of said transcutaneous hollow cylinder slidably received into the upper portion of said deep implant cylinder and extending to the lower end point of said deep implant cylinder;
- d. a stabilizing flange coated on its exterior surface with a material suitable for bonding with biological tissue and slidably mounted on the exterior surface of said deep implant cylinder; and
- e. a removable cap and drainage tube assembly slidably insertable within the upper end of said transcutaneous hollow cylinder.
- 13. The cystostomy tube of claim 12 wherein said flanged upper end comprises a V-shaped notch.
