Abstract
An implantable catheter for use in delivering insulin or other therapeutic fluids is disclosed which uses a novel terminator design to prevent the growth of fibrotic tissue from obstruction the catheter. The catheter takes advantage of fibrotic encapsulation by utilizing a depression in the surface of the terminator which will effectively keep fibrotic tissue spaced sufficiently away therefrom to allow fluid to be infused. In addition to being capable of long term implant, the catheter is implantable in the omentum, enabling the body's natural absorption of insulin to be successfully mimicked.
