  • Publication number: 20230385035
    Abstract: The present technology relates to devices for treating arteries. In several embodiments, for example, the present technology comprises an expandable structure configured to be intravascularly positioned within a lumen of the artery at a treatment site, where the artery has a substantially circular cross-sectional shape at the treatment site prior to deployment of the expandable structure therein. When the expandable structure is in an expanded state and positioned in apposition with the arterial wall at the treatment site under diastolic pressure, the expandable structure may force the artery into a non-circular cross-sectional shape. A cross-sectional area of the artery in the non-circular cross-sectional shape may be less than a cross-sectional area of the artery in the substantially circular cross-sectional shape.

  • Publication number: 20230172717
    Abstract: Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

  • Publication number: 20230165791
    Abstract: An implant for insertion into a punctum of a patient comprises a body. The body has a distal end, a proximal end, and an axis therebetween. The distal end of the body is insertable distally through the punctum into the canalicular lumen. The body comprises a therapeutic agent included within an agent matrix drug core. Exposure of the agent matrix to the tear fluid effects an effective therapeutic agent release into the tear fluid over a sustained period. The body has a sheath disposed over the agent matrix to inhibit release of the agent away from the proximal end. The body also has an outer surface configured to engage luminal wall tissues so as to inhibit expulsion when disposed therein. In specific embodiments, the agent matrix comprises a non-bioabsorbable polymer, for example silicone in a non-homogenous mixture with the agent.
