  • Patent number: 11564596
    Abstract: Systems and methods are disclosed that provide for regular, periodic or continuous monitoring of fluid volume based on direct measurement of an inferior vena cava (IVC) physical dimension using a wireless measurement sensor implanted in the IVC. By basing diagnostic decisions and treatments on changes in an IVC physical dimension, information on patient fluid state is available across the entire euvolemic range of fluid states, thus providing earlier warning of hypervolemia or hypovolemia and enabling the modulation of patient treatments to permit more stable long-term fluid management.

  • Patent number: 11504237
    Abstract: Cardiac valve repair devices with annuloplasty features and associated systems and methods are disclosed herein. A cardiac valve repair device configured in accordance with embodiments of the present technology can include, for example, an atrial fixation member configured to engage tissue within a left atrium proximate to a native mitral valve and a spring mechanism coupled to an inferior edge portion of the atrial fixation member. The spring mechanism has an extended state with a first length corresponding to a dimension of the atrial fixation member in a deployed state and a relaxed state with a shorter length corresponding to a desired dimension of the native valve annulus. When implanted, the spring mechanism contracts the atrial fixation member such that the native mitral annulus anchored to the atrial fixation member reduces in a cross-sectional dimension.

  • Publication number: 20220313426
    Abstract: The present technology is directed to the treatment of cardiac valves. Many embodiments of the present technology comprise an anchor member configured to be positioned at an implantation site proximate a native valve annulus. The anchor member may comprise an expandable structure having a first portion and a second portion. When the first portion is positioned at the implantation site at body temperature and released from a constrained delivery state, the first portion is configured to self-expand into apposition with tissue at or near the annulus to secure the anchor member at the implantation site. The second portion remains in a low-profile state at or around body temperature and is configured to expand into apposition with tissue at or near the annulus when heated above a second temperature greater than the first temperature and body temperature.

  • Patent number: 11406592
    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.

  • Publication number: 20220233840
    Abstract: Mechanical circulatory support systems and methods are disclosed herein. In some examples, the present technology comprises a system for providing cardiac support to a patient where the system comprises a first elongated shaft configured to receive a delivery catheter therethrough, a second elongated shaft, and a pressure source coupled to the first and second elongated shafts. The first elongated shaft may have a distal end portion configured to be intravascularly positioned at a first cardiovascular location, and the second elongated shaft may have a distal end portion configured to be intravascularly positioned at a second cardiovascular location downstream of the first location. Pressure generated by the pressure source pulls blood from the first location proximally through the first shaft to the pressure source, then pushes the blood distally through the second shaft and into circulatory flow at the second cardiovascular location, thereby providing mechanical circulatory support to the patient.

  • Publication number: 20220183865
    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.
