Modification of the catheterization procedure for the totally implantable infusion pump.

The totally implantable infusion pump is a new and expensive device. Once this pump is unpacked and is in contact with a patient, it is impossible to have it resterilized. For this reason, we suggest the use of a separate catheter for catheterization. Once the catheter is successfully placed in the appropriate artery, then the pump can be unpacked and attached to this catheter. If catheterization proves impossible, the pump is still sterile and can be used for the next patient.
