摘要: In some embodiments, a method includes a shaft having a side catheter guide attached thereto via a guide coupler into an inferior vena cava and a superior vena cava such that the guide coupler is disposed in a right atrium, and applying a distal force to a proximal portion of the side catheter guide such that a distal end of the side catheter guide deflects laterally about the guide coupler towards a septum. The method further includes extending a side catheter that is disposed within the side catheter guide distally from the side catheter guide towards and into contact with the septum. The method further includes, with the side catheter in contact with the septum, extending a septum penetrator that is slidably disposed within the side catheter distally from the side catheter such that the septum penetrator pierces the septum.

摘要: The present invention provides devices for treating functional mitral regurgitation and methods of use thereof. The devices translocate a subject's mitral valve in an apical direction. The devices thereby treat mitral regurgitation while preserving a subject's original mitral valve and chordae tendinae.

摘要: Disclosed herein is a bidirectional intravascular cannula, or catheter, that is configured to provide and return blood in a patient bidirectionally. The bidirectional intravascular cannula is configured to reduce or obviate the need for a second cannula, such as currently available unidirectional cannulae, to be placed in a second or opposite direction of flow. Users would include cardiac surgeons, intensivists, vascular surgeons, ER doctors, IR doctors and cardiologist who use peripheral cannulation for ECLS or cardiopulmonary bypass. The cannula allows continued flow to a patient's limb even with the cannula proximally in the vessel. The cannula further allows larger size cannula to be placed without the need for additional distal catheter placement.
