Patent Images
1. A subcutaneously tunneled catheter set comprising:
- a first multilumen catheter having an exit port for each lumen at one end, said catheter being used for insertion into a patient;
a second multilumen catheter including reinforcement means for preventing the lumens from kinking closed;
a housing for connecting the lumens of said first multilumen catheter with the lumens of said second multilumen catheter, said housing having multiple ports on one side connected by conduits to multiple ports on an opposite side; and
a tissue cuff connected around the outside of said housing.

Abstract
A subcutaneously tunneled catheter set is disclosed in which a first multilumen catheter is connected to a second reinforced multilumen catheter. A tissue cuff is located near the connection between the two catheter tubes. The disclosure includes a multilumen connector made from a housing that provides conduits between two sets of ports which connect to catheter tubes at either end. The tissue cuff is connected around the outside of the multilumen connector. A multilumen locking connector is provided so that the subcutaneously tunneled multilumen catheter set may be connected directly to an exterior multilumen catheter tube.

3. A subcutaneously tunneled catheter set comprising:
-
a first multilumen catheter having an exit port for each lumen at one end, said catheter being used for insertion into a patient; a second multilumen catheter including reinforcement means for preventing the lumens from closing when said catheter is bent; means for connecting the lumens of said first multilumen catheter with the lumens of said second multilumen catheter; a tissue cuff located near the connection between said first and second catheters for anchoring the catheter set to the patient'"'"'s skin; said second multilumen catheter being connected to said connecting means at one end and to a lock adapter at the other end, said lock adapter including a plurality of ports that fit into the lumens of said second catheter and a plurality of conduits each connected to a different one of said ports; and said lock adapter being connectable with a second lock adapter to provide communication between said subcutaneously tunneled catheter set and a third multilumen catheter. - View Dependent Claims (4, 5, 6)
