Medical treatment system using measurement data from multiple sensors
A medical treatment system for determining administration of medications to a patient is disclosed. The system uses a plurality of sensors to perform a first set of physiologic measurements in a right side of the heart and a second set of physiologic measurements in a left side of the heart. The system also includes a receiver configured to receive measurement data regarding the first and second sets of physiologic measurements and output to a display device the received measurement data.
SHUNT FOR REDISTRIBUTING ATRIAL BLOOD VOLUME
Systems and methods for implanting a shunt for regulating blood pressure between a patient's left and right atria are provided. The shunt comprises an anchor having a neck region, first and second end regions, and a conduit affixed with the anchor formed of a biocompatible material that is resistant to transmural and translation tissue ingrowth and that reduces a risk of paradoxical embolism. The shunt may be advanced through the sheath until the first region protrudes from the sheath and self-expands within the left atrium. The shunt and the sheath may then be retracted until the first region contacts the left side of the atrial septum. The sheath may further be retracted until the counterforce exerted by shunt tension on the atrial septum overcomes the friction of the retained portions of the shunt such that the second region is exposed from the sheath and self-expands within the second atrium.
Tissue protecting devices for treatment of congestive heart failure and other conditions
According to one embodiment, a protective device for use in congestive heart failure treatments, and other treatments, includes a control mechanism, an elongate shaft, and a protective plate. The control mechanism is coupled with a proximal end of the elongate shaft and the protective plate is pivotably coupled with a distal end of the elongate shaft. The elongate shaft enables the protective plate to be inserted within a body and navigated distally of a heart wall. The protective plate has a relatively wide and thin body portion and is pivotable relative to the elongate shaft by operation of the control mechanism. Pivoting and/or navigating of the protective plate within the body allows the protective plate to be positioned adjacent the heart wall to shield body organs or tissue surrounding the heart wall from being damaged by surgical instruments inserted through the heart wall.
TRANSCATHETER SYSTEM AND METHOD FOR REDUCING TRICUSPID REGURGITATION
The present invention relates to a system and method for transcatheter treatment for tricuspid regurgitation. The system for transcatheter treatment for tricuspid regurgitation, according to one preferred embodiment of the present invention, includes: the coronary sinus tube inserted into the coronary sinus; and the tricuspid valve tube traversing the tricuspid valve, wherein the coronary sinus tube and the tricuspid valve tube communicate with each other or are adjacent to each other within a range of predetermined length at an upper side and are separate from each other at a lower side, and a blocking member for blocking a space generated by incomplete closing of the tricuspid valve is provided at a lower part of the tricuspid valve tube or between the coronary sinus tube and the tricuspid valve tube.
PERCUTANEOUS HEART VALVE PROSTHESIS
A percutaneous heart valve prosthesis including a collapsible valve body frame has a first end and a second end. The valve body frame is formed by a plurality of sub-frame members, each sub-frame member having a general form of a diamond with acute-angled vertices and oblique-angled vertices, wherein adjacent sub-frame members are joined at the oblique-angled vertices. A flexible skirt made from pericardial material extends around a periphery of the valve body frame. A one-way valve including a plurality of flexible valve leaflets is positioned within the valve body frame. The first end of the valve body frame is sized to pass through a valve orifice associated with a heart valve to be replaced and the second end of the valve body frame is sized so as not to pass through a valve orifice.
Methods and devices for tissue grasping and assessment
Devices, systems and methods are provided for stabilizing and grasping tissues such as valve leaflets, assessing the grasp of these tissues, approximating and fixating the tissues, and assessing the fixation of the tissues to treat cardiac valve regurgitation, particularly mitral valve regurgitation.
DEVICE AND ASSEMBLY TO REPAIR A HEART VALVE
An assembly for reshaping a cardiac ventricle in a patient comprising an implantable device for reshaping a ventricle comprising a tether, a non-implantable tool which is detachably connectable to said implantable device and has a proximal portion and a distal portion opposite to said proximal portion; the implantable device further comprises an active anchor adapted to be detachably connected to the distal portion of the tool; the active anchor comprises an abutment portion adapted to abut against a structure of the ventricle; the active anchor of the implantable device comprises an adjustment device adapted to adjust the tensional state of the tether; the distal portion of the tool comprises an adjustment key adapted to cooperate with the adjustment device of the active anchor; the proximal portion of the tool comprises a maneuvering interface which is operatively connectable to said adjustment key for adjusting the tensional state of the tether by acting on the maneuvering interface of the proximal portion of the tool.
Mechanical treatment of heart failure
Apparatus is provided for treating heart failure, the apparatus including one or more propeller blades and a controller, which is configured to rotate the one or more propeller blades to produce continuous non-pulsatile blood flow not synchronized with a cardiac cycle of a subject. An intra-atrial anchor includes a stent surrounding the one or more propeller blades. The intra-atrial anchor is coupled to the one or more propeller blades and configured to be anchored in a left atrium of the subject so as to position the one or more propeller blades in the left atrium oriented such that the one or more propeller blades, when rotated by the controller, draw blood from the left atrium and expel the blood in the left atrium toward a mitral valve, thereby increasing atrial pressure above the mitral valve. Other embodiments are also described.
Heart shape preserving anchor
Embodiments of a heart shape preserving anchor are disclosed herein. The heart shape preserving anchor can include a frame having one or more wings extending from a lower end of the frame. The frame can be sized and shaped to distribute forces over a large surface area thereby reducing pressures applied on the heart. The anchor can include a tether for coupling to a prosthesis, such as a replacement heart valve prosthesis. In some embodiments, the anchor can include a tether adjustment mechanism which can be wirelessly operated to adjust a length of the tether relative to the frame.
Left Atrial Appendage Stasis Reduction
Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.
