Claims14
A method of modulating renal function in a patient comprising:
- implanting an occlusive device in the patient, the occlusive device comprising a semi-permeable membrane, the occlusive device configured to expand or contract based on the passage of a fluid across the semi-permeable membrane;
- and
- expanding the occlusive device in response to decreases in osmolality of a bodily fluid;
- wherein expanding the occlusive device results in occluding a renal lymphatic vessel with the occlusive device;
- and
- contracting the occlusive device in response to increases in osmolality of the bodily fluid.
A method of treating a hypervolemic state including heart failure decompensation and/or hypertension comprising:
- implanting an occlusive device in the patient, the occlusive device comprising a semi-permeable membrane, the occlusive device configured to expand or contract based on the passage of a fluid across the semi-permeable membrane;
- and
- expanding the occlusive device in response to decreases in osmolality of a bodily fluid;
- wherein expanding the occlusive device results in occluding a renal lymphatic vessel with the occlusive device;
- and
- contracting the occlusive device in response to increases in osmolality of the bodily fluid.
