  • Publication number: 20220265427
    Abstract: Among other things, there are disclosed embodiments of belts or bands that can be used in treatments for tricuspid valve regurgitation. In some embodiments, such belts may be heat-set in a particular configuration to effectively decrease tricuspid annulus when deployed around the atrioventricular groove. Embodiments include one or more tensioning sutures for applying cinching or tightening to belts when deployed, and structure for effectively distributing force during such tightening.

  • Publication number: 20150305750
    Abstract: An occlusion device comprising a plurality of expandable hydrophilic foam elements is described. When the device is deployed to a body vessel or a body cavity, it expands radially due to uptake of liquid from the body fluids with which it is in contact. The device may optionally have a surrounding meshwork, an inner spring, and a screw-type deployment mechanism. A method of deploying the device is also provided.
