Systems and Methods for Treating Pulmonary Edema

摘要

Various systems and methods are provided for treating pulmonary edema. In general, a pump can be configured to be implanted within a patient at risk of developing edema. The pump can be configured to pump fluid out of the patient's lungs, e.g., out of the patient's interstitial and alveolar spaces. The pump can be configured to be fully implanted within the patient's body. The pump can be configured to continuously pump fluid, or the pump can be configured to be selectively actuatable in response to a trigger event. In an exemplary embodiment, the pump can include an inflow port coupled to an inflow tube in fluid communication with a lymphatic vessel of the patient, and can include an outflow port coupled to an outflow tube in fluid communication with a vein of the patient.

主权项

1. A system for treatment of edema, comprising:
a pump configured to be implanted in a body of a patient; an inflow tube fluidically coupled to an inflow port of the pump and configured to be implanted into the body of the patient so as to bring the inflow port into fluid communication with a lymphatic vessel of the patient; and an outflow tube fluidically coupled to an outflow port of the pump and configured to be implanted into the body of the patient so as to bring the outflow port into fluid communication with a vein in the body of the patient such that the pump is operative to pump fluid from the lymphatic vessel to the vein.
