Aortic Balloon Pumping Patents (Class 600/18)
  • Patent number: 12151092
    Abstract: Mechanical circulatory supports configured to operate in series with the native heart are disclosed. In an embodiment, a centrifugal pump is used. In an embodiment, inlet and outlet ports are connected into the aorta and blood flow is diverted through a lumen and a centrifugal pump between the inlet and outlet ports. The supports may create a pressure rise between about 40-80 mmHg, and maintain a flow rate of about 5 L/min. The support may be configured to be inserted in a collinear manner with the descending aorta. The support may be optimized to replicate naturally occurring vortex formation within the aorta. Diffusers of different dimensions and configurations, such as helical configuration, and/or the orientation of installation may be used to optimize vortex formation. The support may use an impeller which is electromagnetically suspended, stabilized, and rotated to pump blood.

  • Patent number: 12115327
    Abstract: Sensor devices and methods of operating for use with catheter-based treatments of microcardial microvascular obstruction by infusion of fluids having protective agents into vasculature are provided herein. Such catheter devices can include a first lumen configured for advancement over a guidewire and for passage of fluid having protective agents after removal of the guidewire and a second lumen for inflation of an angioplasty balloon and can further include a temperature and/or pressure sensor mounted on the catheter body. Such catheter devices can further include use of a distal occlusive membrane between the angioplasty balloon and distal end to facilitate infusion into microvasculature. The occlusive membrane can be deployed by relative movement of concentric channels, thereby reducing the need for additional lumen while optimizing the size of the catheter device and lumens.

  • Patent number: 10842974
    Abstract: Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.

  • Patent number: 10806908
    Abstract: A balloon catheter for treating elongate diseased vessels with a variable diameter, comprising a pre-stretched balloon and a catheter shaft, which forms a wire lumen embodied to guide a guide wire and forms a liquid lumen by which a liquid can be fed to the balloon. The balloon is fastened to a first catheter shaft element at a first, proximal fastening site and fastened to a second catheter shaft element at a second, distal fastening site, wherein the second fastening site is movable along a longitudinal axis of the catheter shaft in relation to the first fastening site. The balloon surrounds a section of the catheter shaft which extends between the first and second fastening sites. Here, the section of the catheter shaft surrounded by the balloon encloses different regions of the catheter shaft with a changing longitudinal extent of the balloon.

  • Patent number: 10806899
    Abstract: Articulation devices, systems, and methods for articulating elongate flexible structures can locally contract a flexible elongate frame or skeleton of an elongate flexible body such as a catheter. Balloons along one side of an axial segment of the elongate flexible body can be inflated so as to help define a resting shape of the elongate body. The skeleton may have pairs of corresponding axially oriented surface regions coupled to each other by a loop of a deformable helical coil structure. Balloons may be between the regions, and the pairs may be separated by an offset that increases when the axis of the skeleton is axially compressed. Inflation of the balloons can axially contract or shorten the skeleton adjacent the balloons so that the elongate body bends toward the balloons.

  • Patent number: 10743932
    Abstract: A catheter adapted for ablation has multiple dedicated irrigation tubings to supply fluid to their respective electrode or set of electrodes. The tubings provide parallel flow pathways through the catheter where irrigation fluid is delivered to irrigated tip and/or ring electrodes which can accomplish uni-polar or bi-polar ablation. Such separate and dedicated fluid pathways allow fluid to be delivered to the corresponding electrode or set of electrodes at different flow rates. An integrated ablation system using such catheter has an ablation energy source and an irrigation pump with multiple pump heads that can operate independently of each other. An integrated irrigation tubing set is included to extend between the fluid source and the catheter, with each pump head being able to act on a different tubing that delivers fluid to a different electrode or set of electrodes.
