First Claim
Patent Images
1. A medical system, comprising:
- a drug provisioning component to administer a therapeutically effective amount of a chimeric natriuretic peptide to a subject suffering from kidney disease alone, heart failure alone, concomitant kidney disease and heart failure or cardiorenal syndrome, said drug provisioning component maintaining a plasma concentration of the chimeric natriuretic peptide within a specified range,wherein the drug provisioning component administers the chimeric natriuretic peptide subcutaneously or intramuscularly.

Abstract
Medical systems and methods for treating kidney disease alone, heart failure alone, kidney disease with concomitant heart failure, or cardiorenal syndrome are described. The systems and methods are based on delivery of a chimeric natriuretic peptide to a patient. Methods for increasing peptide levels include direct peptide delivery via either an external or implantable programmable pump.

55. A method for administering a chimeric natriuretic peptide to a subject suffering from kidney disease alone, heart failure alone, concomitant kidney disease and heart failure or cardiorenal syndrome, comprising:
-
administering the chimeric natriuretic peptide to the subject using a drug provisioning component to maintain a plasma level of the chimeric natriuretic peptide at a steady state concentration, wherein the drug provisioning component administers the chimeric natriuretic peptide subcutaneously or intramuscularly. - View Dependent Claims (56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)

69. A method for treating a subject suffering from kidney disease alone, heart failure alone, or with concomitant kidney disease and heart failure or cardiorenal syndrome, comprising:
administering a therapeutically effective amount of a chimeric natriuretic peptide to the subject by subcutaneous infusion, wherein the administration of the chimeric natriuretic peptide has one or more renal protective effects or cardiovascular effects. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76, 79, 80, 81)
-
77. The method of 69, wherein the one or more renal protective effects includes lowering the presence of albumin in urine or reducing an increase in albumin in urine.
-
78. The method of 69, wherein the one or more renal protective effects includes one or more selected from the group consisting of maintaining renal cortical blood flow and lowering the presence of protein in urine or reducing an increase in protein in urine.
