1. A method, comprising the steps of:
- continuously administering a natriuretic peptide to a subject suffering from kidney disease alone, heart failure alone, or with concomitant kidney disease and heart failure or cardiorenal syndrome using a drug provisioning component to chronically deliver a therapeutically effective amount of the natriuretic peptide to the subject at a rate which maintains a subject-specific mean steady state plasma concentration, andmaintaining the plasma concentration of the natriuretic peptide within a specified range,wherein the specified range is pre-determined by administering a test dose of the natriuretic peptide to the subject so that the specified range is not greater than a plasma concentration of the natriuretic peptide reached in the subject during either a subcutaneous bolus at 18,000 ng/kg or a 1 hour intravenous infusion of the natriuretic peptide at 300 ng/(kg·
min) based on the subject'"'"'s body weight, andwherein the drug provisioning component delivers the natriuretic peptide subcutaneously for multiple days.

Abstract
Medical systems and methods for treating kidney disease alone, heart failure alone, chronic kidney disease with concomitant heart failure, or cardiorenal syndrome are described. The systems and methods are based on delivery of a natriuretic peptide such as Vessel Dilator to a subject. Methods for increasing and maintaining peptide levels at a certain concentration include direct peptide delivery via either an external or implantable programmable pump.

8. A method for administering a natriuretic peptide to a subject suffering from kidney disease alone, heart failure alone, or with concomitant kidney disease and heart failure or cardiorenal syndrome, comprising:
-
continuously administering the natriuretic peptide to the subject using a drug provisioning component to maintain a subject-specific plasma level of the natriuretic peptide at a steady state concentration at a specified range, wherein the specified range is pre-determined by administering a test dose of the natriuretic peptide to the subject and the specified range maintains a plasma level of the natriuretic peptide at a steady state concentration from about 0.5 to about 60 ng/mL and the drug provisioning component administers the natriuretic peptide subcutaneously for multiple days, the natriuretic peptide is selected from any one of long-acting natriuretic peptide (LANP), kaliuretic peptide (KP), urodilatin (URO), atrial natriuretic peptide (ANP), vessel dilator (VD) and brain natriuretic peptide (BNP), and the administration of the natriuretic peptide has one or more renal protective, cardiovascular protective or renal or cardiovascular protective effects. - View Dependent Claims (9, 10, 11, 12, 13)
