Claims11
A method for implanting a tissue bondable cystostomy tube in a patient comprising:
- a. surgically implanting a subcutaneous hollow cylinder coated on its exterior surface with a material suitable for bonding with biological tissue in the region of the bladder membrane, said subcutaneous hollow cylinder containing a plug;
- b. allowing the subcutaneous hollow cylinder to remain in the patient for a sufficient period of time for tissue bonding to occur;
- c. surgically excising a circular portion of skin and subcutaneous fat located above said subcutaneous hollow cylinder and removing the plug from said subcutaneous hollow cylinder;
- d. surgically implanting a transcutaneous hollow cylinder having an upper end and a lower end and coated on its exterior surface with a material suitable for bonding with biological tissue by passing the transcutaneous hollow cylinder through the opening created by the excision of skin and subcutaneous fat and slidably inserting the lower end of the transcutaneous hollow cylinder into the subcutaneous hollow cylinder;
- and
- e. allowing the subcutaneous and transcutaneous hollow cylinders to remain in the patient for a sufficient period of time for tissue bonding to occur.

A method for implanting a tissue bondable cystostomy tube in a patient comprising:
- a. surgically implanting a subcutaneous hollow cylinder having a stabilizing slipover disc sleeve centrally located on its exterior surface in the region of the bladder membrane, said subcutaneous hollow cylinder containing a plug and both said subcutaneous hollow cylinder and said stabilizing slipover disc sleeve coated on their exterior surfaces with a material suitable for bonding with biological tissue;
- b. anchoring the stabilizing slipover disc sleeve to muscular fascia in the patient using sutures to ensure proper alignment of the transcutaneous hollow cylinder and subcutaneous hollow cylinder;
- c. allowing the subcutaneous hollow cylinder to remain in the patient for a sufficient period of time for tissue bonding to occur;
- d. surgically excising a circular portion of skin and subcutaneous fat located above said subcutaneous hollow cylinder and removing the plug from said subcutaneous hollow cylinder;
- e. passing a transcutaneous hollow cylinder having an upper end and a lower end through the opening created by the excision of skin and subcutaneous fat and inserting the lower end of the transcutaneous hollow cylinder into the subcutaneous hollow cylinder;
- and
- f. allowing the subcutaneous and transcutaneous hollow cylinders to remain in the patient for a sufficient period of time for tissue bonding to occur.
