ABSTRACT:
A catheter having a microtextured exterior surface portion is employed to deliver fluids such as medicaments internally to the parenchyma of an organ or other internal living bodily tissue. The microtextured exterior surface portion promotes cellular tissue ingrowth into the textured surface, thereby creating an effective fluid seal in the bore formed in the tissue and inhibiting the body's rejection response to the catheter. The fluid seal prevents the reflux of infused fluid from the distal end of the catheter from the bore opening and permits controlled delivery of fluid to affected tissue.
