Abstract
Devices and methods of treating conditions cause or exacerbated by excessive fluid pressures or retentions, such as pulmonary hypertension, that involves shunting excessive fluid pressure from one bodily chamber or vessel to another bodily chamber or vessel.
Claims18
A method for treating a medical condition in a circulatory system of a human comprising:
- identifying a location in the circulatory system where a superior vena cava overlays a pulmonary artery;
- puncturing said superior vena cava and said pulmonary artery at said location;
- inserting a shunt into said punctured location;
- securing said shunt at said punctured location;
- and,
- diverting blood in said circulatory system from said pulmonary artery into said superior vena cava.
3 more elements
A method of treating a condition in a circulatory system of a human comprising:
- Creating a shunt between a superior vena cava and a pulmonary artery that are not connected prior to creating said shunt;
- wherein said pulmonary artery has a higher pressure than said superior vena cava;
- and,
- shunting part of a blood flow in said pulmonary artery through said shunt, into said superior vena cava, and allowing said part of said blood flow into a right atrium of a heart.
1 more element
A method for treating a medical condition in a circulatory system of a human comprising:
- puncturing a superior vena cava and a pulmonary artery;
- inserting a shunt into said superior vena cava and said pulmonary artery;
- expanding the shunt within the superior vena cava and within the pulmonary artery;
- and,
- diverting part of a blood flow in said pulmonary artery through said shunt, into said superior vena cava, and allowing said blood flow into a right atrium of a heart.
