<P>PROBLEM TO BE SOLVED: To provide a small medication infusion apparatus and an infusion method for reducing the replenishing frequency and replenishing time of a medication. <P>SOLUTION: An implantable infusion apparatus has a medication storage part for storing the medication, and a carrier storage part for storing a carrier. The entire apparatus including both storage parts is typically disposed in a housing formed of stainless steel, titanium or any other strong corrosion resistant biocompatible material. The medication storage part and the carrier storage part are accessed through a medication access port and a carrier access port respectively. These access ports are covered with a medication compound septum and a carrier compound septum respectively. The carrier storage part is larger than the medication storage part and thus holds a larger volume than the medication storage part. To reduce the size of the implantable infusion apparatus, the medication is highly concentrated to many times the dosage required. The concentrated medication is then diluted with the carrier, to the proper dose, before it is discharged to a patient. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
