Abstract
The present disclosure relates to improved capabilities for stabilizing and regulating atrial pressure with a shunt in the atrial septum or a stent in the coronary sinus. The disclosure also includes sensing, monitoring, drug therapy and control capabilities to provide improved treatment of patients with heart disease and other cardiac related conditions.
Core Innovation
The patent describes a system and device for treating a heart condition using a body element or flow control device mounted on an atrial septum of a patient. The body element includes a cylindrical core segment defining a passage and first and second annular flanges adapted to engage first and second surfaces of the atrial septum. A motor includes a stationary portion and a movable portion, and the movable portion is anchored to a movable flap.
The movable flap is configured to move away from the stationary portion of the motor, forming an opening of the atrial septum and allowing blood flow between the left atrium and right atrium. In another embodiment, a flow control device includes a stationary portion and a movable flap valve mounted on the atrial septum, with mounting portions extending within both the left atrium and the right atrium.
A sensor mounted within the patient is in communication with the flow control device and provides information to control the movable flap valve such that the movable flap valve moves closer or away from the stationary portion based on information obtained by the sensor. The disclosed system supports monitoring and control using sensors and communication, where the controlled flap movement regulates blood flow through the atrial septum.
Claims Coverage
The partial content identifies two independent claims, each focused on atrial-septum blood-flow control using a motor-driven movable flap or a sensor-driven movable flap valve. Across the independent claims, the inventive features center on the atrial-septum-engaging structure with annular flanges and cylindrical core segment, and on the flap valve movement controlled by sensor information.
Atrial-septum engaging body element with cylindrical core segment and first and second annular flanges
A body element comprising a cylindrical core segment defining a passage, a first annular flange adapted to engage a first surface of an atrial septum, and a second annular flange adapted to engage a second surface of the atrial septum.
Motor anchored movable flap forms an atrial septum opening
A motor mounted to the body element includes a stationary portion and a movable portion, wherein the movable portion is anchored to a movable flap, and the movable flap is configured to move away from the stationary portion of the motor forming an opening of the atrial septum and allowing blood flow between left atrium and right atrium.
Flow control device with stationary portion and movable flap valve mountable on atrial septum
A flow control device comprising a stationary portion and a movable flap valve for mounting on an atrial septum, wherein the means for mounting includes portions within the left atrium and portions within the right atrium.
Sensor-driven positioning of movable flap valve based on sensor information
A sensor mounted within the patient and in communication with the flow control device, wherein the movable flap valve is configured to move closer or away from the stationary portion based on information obtained by the sensor.
Across the independent claims, the main inventive coverage is directed to an atrial-septum mounted blood-flow control element that includes annular flange engagement and a movable flap. One independent claim emphasizes motor-driven opening of the atrial septum to allow left atrium to right atrium blood flow, and the other emphasizes sensor-driven movement of a flap valve toward or away from a stationary portion based on sensor information.
Stated Advantages
Allows blood flow between left atrium and right atrium by forming an opening of the atrial septum.
Documented Applications
Treating a heart condition in a patient using an implantable interatrial pressure venting/flow control system with an atrial septal opening.
Monitoring and control in conjunction with the flow control using sensors and communication.
