The implantable component may include a compliant member, e.g., balloon, coupled to a reservoir via a conduit. Preferably, the compliant member is adapted to be implanted in a pulmonary artery and the reservoir is adapted to be implanted subcutaneously. The external components may include a clinical controller component, monitoring software configured to run a clinician's computer, a patient monitoring device, and a mobile application configured to run on a patient's mobile device. ## Claims ### Claim 1 A system for treating pulmonary hypertension, the system comprising: an implantable component comprising a compliant member coupled to a reservoir via a conduit, the compliant member adapted to be implanted in a pulmonary artery and the reservoir adapted to be implanted subcutaneously, the implantable component further comprising a sensor disposed within the reservoir; and an external monitoring component configured to wirelessly activate the sensor to cause the sensor to sense humidity within the implantable component, wherein the sensor is configured to transmit a signal indicative of the sensed humidity to the external monitoring component. ### Claim 2 (depends on 1) The system of claim 1, wherein the external monitoring component is configured to transmit the signal to a mobile device, the mobile device configured to display information indicative of humidity within the implantable component based on the signal. ### Claim 3 (depends on 2) The system of claim 2, wherein the mobile device is configured to run a routine to generate an alert if the sensed humidity is above a first predetermined threshold or below a second predetermined threshold. ### Claim 4 (depends on 1) The system of claim 1, wherein the external monitoring component comprises an inductive coil. ### Claim 5 (depends on 4) The system of claim 4, wherein the inductive coil is configured to transmit power to the sensor. ### Claim 6 (depends on 1) The system of claim 1, wherein the external monitoring component comprises a radio frequency (RF) transceiver. ### Claim 7 (depends on 6) The system of claim 6, wherein the RF transceiver is configured to transmit power to the sensor. ### Claim 8 (depends on 1) The system of claim 1, wherein the external monitoring component comprises a user interface. ### Claim 9 (depends on 8) The system of claim 8, wherein the user interface is configured to display information indicative of humidity within the implantable component based on the signal. ### Claim 10 (depends on 1) The system of claim 1, wherein the sensor is further configured to sense pressure within the reservoir, volume within the reservoir, temperature within the reservoir, fluid flow rate within the reservoir, fluid concentration within the reservoir, or pH within the reservoir, or any combination thereof. ### Claim 11 (depends on 1) The system of claim 1, further comprising an additional sensor disposed within the reservoir, the additional sensor configured to sense pressure within the reservoir, volume within the reservoir, temperature within the reservoir, fluid flow rate within the reservoir, fluid concentration within the reservoir, or pH within the reservoir, or any combination thereof. ### Claim 12 (depends on 1) The system of claim 1, wherein the compliant member has a tapered shape configured to reduce billowing of the compliant member. ### Claim 13 (depends on 1) The system of claim 1, wherein the implantable component further comprises an anchor, the anchor configured to secure the compliant member within the pulmonary artery. ### Claim 14 (depends on 13) The system of claim 13, wherein the anchor is coupled to the conduit distal to the compliant member and the anchor has a plurality of petals. ### Claim 15 (depends on 13) The system of claim 13, wherein the compliant member is configured to be detachable from at least a portion of the anchor in vivo such that the compliant member is replaceable while at least the portion of the anchor remains implanted. ### Claim 16 (depends on 13) The system of claim 13, wherein the anchor is configured to be delivered in a contracted state within a sheath and to expand to a deployed state when exposed from the sheath. ### Claim 17 A method for treating pulmonary hypertension, the method comprising: providing an implantable component comprising a compliant member, a reservoir, and a conduit, the compliant member adapted to be disposed in a pulmonary artery, the reservoir adapted to be disposed subcutaneously, and the conduit adapted to be coupled between the compliant member and the reservoir; providing an external monitoring component; wirelessly activating a sensor disposed within the reservoir via the external monitoring component to cause the sensor to sense humidity within the implantable component; and transmitting a signal indicative of the sensed humidity from the sensor to the external monitoring component. ### Claim 18 (depends on 17) The method of claim 17, further comprising transmitting the signal from the external monitoring component to a mobile device, the mobile device configured to display information indicative of humidity within the implantable component based on the signal. ### Claim 19 (depends on 18) The method of claim 18, further comprising generating an alert if the sensed humidity is above a first predetermined threshold or below a second predetermined threshold. ### Claim 20 (depends on 17) The method of claim 17, further comprising displaying information indicative of the sensed humidity on a user interface of the external monitoring component.
