The right pulmonary artery or right branch of the pulmonary artery, longer and larger than the left, runs horizontally to the right, behind the ascending aorta and superior vena cava and in front of the right bronchus, to the root of the right lung, where it divides into two branches. The lower and larger of these goes to the middle and lower lobes of the lung; the upper and smaller is distributed to the upper lobe. This article incorporates text from a public domain edition of Gray's Anatomy.
Devices For Fixing A Sensor In A Lumen
Sensing devices and methods of implanting sensing devices within an anatomical vessel network of a patient are provided. In one method, a fixation element (e.g., a stent or coil) of the sensing device is expanded into firm contact with a wall of a main anatomical vessel (e.g., a right pulmonary artery), and a stabilization element of the sensing device is placed into contact with a wall of an anatomical vessel branch of the main anatomical vessel. In another method, a first fixation element of the sensing device is expanded into firm contact with the wall of the main anatomical vessel (e.g., a right pulmonary artery) at a longitudinal location proximal to the anatomical vessel branch, and a second fixation element of the sensing device is expanded into firm contact with the wall of the main anatomical vessel at a longitudinal location distal to the anatomical vessel branch.

Pulmonary artery valve replacement device and support thereof
ActiveCN103202735AAvoid surgical risksLess likely to cause harmHeart valvesTectorial membranePulmonary Artery Branch
The invention discloses a pulmonary artery valve replacement device and a support thereof. The support comprises a valve fixing part, the top edge of the valve fixing part and a support part used for supporting a left pulmonary artery or / and right pulmonary artery are connected through a transitional section, and both the valve fixing part and the support part are of cylindrical structures. The transitional section is provided with a transitional arc surface fittingly contacting with the inner wall of blood vessels. The pulmonary artery valve replacement device comprises a pulmonary artery valve support, an artificial valve is arranged in the valve fixing part, and the valve fixing part is provided with a tectorial membrane below the artificial valve. The pulmonary artery valve support and the pulmonary artery valve replacement device can solve two problems that backflow of pulmonary artery valve and restenosis of pulmonary artery after pulmonary artery valve operation at the same time and are high in stability, operation risk of support displacement is avoided, damage of blood vessels are less prone to causing, stenosis of pulmonary artery branches is solved and repeated implanting of multiple supports is not needed.

Variable orifice flow
Described herein are shunt devices configured to achieve a targeted reduction in peak systolic pressure by percutaneous ly shunting from the superior vena cava to the right pulmonary artery. The shunt devices include a check valve with a cracking pressure to preserve a minimal transpulmonary pressure. Also described herein are flow diversion devices placed between pulmonary circulation vessels and venous vessels. The disclosed flow diversion devices are physiologically responsive through an adjustable orifice that can be adjusted after initial implantation through a non-invasive or minimally invasive procedure. Disclosed herein are flow control systems that are configured to reduce recruitment of blood from the splanchnic system. The flow control systems include a variable orifice constrictor (e.g., a covered stent) and a controller that delivers energy to the constrictor to reduce the cross-sectional area of the lumen through the variable orifice constrictor.

Pulmonary shunt systems
A method may involve creating a first opening in a right pulmonary artery and a second opening in a superior vena cava. A shunt may be percutaneously delivered into the first opening and the second opening. A stent may be percutaneously delivered into the superior vena cava adjacent to the shunt. The stent can comprise a covering to at least partially prevent flow of blood from the shunt through the stent and / or may be at least partially flexible to allow the stent to bend away from walls of the superior vena cava in response to inflow of blood through the shunt. The stent may be sized to seal against the superior vena cava at a first end and a second end of the stent to trap blood between the stent and the walls of the superior vena cava.
