Abstract
A method of maintaining a locking fluid in an implanted catheter including positioning a catheter assembly in a patient, the catheter assembly including a first lumen having a closed first distal end and a first proximal end, and a second lumen having a closed second distal end and a second proximal end and injecting the locking fluid into the first and second proximal ends at a low pressure such that the locking fluid enters each lumen without opening the respective closed distal end. A method of withdrawing the locking fluid is also provided.
Claims8
A method of maintaining a locking fluid in an implanted catheter comprising:
- positioning a catheter assembly in a patient, the catheter assembly including a first lumen having a closed first distal end and a first proximal end, and a second lumen having a closed second distal end and a second proximal end;
- and
- injecting the locking fluid into the first and second proximal ends at a low pressure such that the locking fluid enters each lumen without opening the respective closed distal end.
A method of removing a lock solution from an implanted catheter comprising:
- positioning a catheter assembly in a patient, the catheter assembly including a first lumen having a closed first distal end and a first proximal end and a second lumen having a closed second distal end, a second proximal end, and at least one closed flap disposed proximal of the second distal end;
- introducing lock solution into the catheter;
- withdrawing the lock solution from the first proximal end with a first force such that the first distal end opens to allow blood into the first lumen;
- and
- withdrawing the lock solution from the second proximal end with a second force such that the at least one flap opens to allow blood into the second lumen.
