Abstract
Systems and methods for closed-loop control of heart failure interventional therapies using closed-loop feedback from vascular implanted cardiac health status sensors are disclosed.
Claims40
A heart failure interventional method with closed-loop control, comprising:
- continuously or intermittently receiving from a patient-implanted vascular sensor implanted in the patient's inferior vena cava (IVC) a signal indicative of a dimension or change in dimension of the IVC, said patient-implanted vascular sensor configured to generate and wirelessly deliver said signal to a control unit outside the patient's IVC;
- receiving said signal at the control unit and correlating the received signal to a patient fluid volume state;
- and
- automatedly modulating a therapy delivered by a therapeutic device continuously or intermittently in a closed loop based at least in part on the correlated patient fluid volume state in response to the received signal.

A heart failure interventional method with closed-loop control based on real-time patient fluid status, comprising:
- implanting a wireless vascular lumen dimension sensor in a patient vena cava;
- wirelessly receiving from said vascular lumen dimension sensor implanted in the vena cava a signal indicative of a dimension or change in dimension of the vena cava, wherein said signal is continuous or interment and when intermittent said intermittent signal occurring at programmed intervals;
- correlating the received signal from the vascular lumen dimension sensor to a patient fluid volume state as said signal is received;
- receiving the patient fluid volume state in a therapeutic device controller;
- and
- automatedly modulating a therapy delivered by the therapeutic device communicating with the therapeutic device controller in response to the received patient fluid volume state correlated from the vena cava lumen dimension sensor signal.

A heart failure interventional system with closed-loop control, comprising:
- a cardiac health status monitoring system comprising a wireless vascular implant and control unit, wherein the wireless vascular implant is configured to generate and wirelessly deliver a signal containing information indicative of a patient cardiac health status parameter to the control unit, said control unit being configured to process said signal to determine a value for the cardiac health status parameter continuously or at programed intervals;
- a therapeutic device including a processor configured to execute instructions to modulate therapeutic intervention continuously or at programed intervals based at least in part on the determined value for the patient cardiac health status parameter;
- and
- a communication link between said monitoring system and said therapeutic device;
- and
- wherein the wireless vascular implant is a wireless vena cava dimension sensor and said patient cardiac health status parameter comprises a dimension or change in dimension of the vena cava.
3 more elements
A heart failure interventional system with closed-loop control based on real-time patient fluid status, comprising:
- an inferior vena cava (IVC) fluid monitoring system comprising a wireless IVC implant configured to generate and wirelessly deliver to an external controller a signal indicative of a dimension or change in dimension of the IVC, said dimension or change in dimension being correlated to a patient fluid state by the external controller continuously or at programed intervals;
- one or more heart failure therapeutic devices controlled by one or more processors configured to execute instructions to modulate therapeutic intervention continuously or at programed intervals based on patient fluid state as determined by the IVC fluid monitoring system;
- and
- a communications link between said IVC fluid monitoring system and said one or more processors.
