  • Patent number: 11660191
    Abstract: A distal end of a guide catheter is transvascularly advanced into a left ventricle of a heart of a subject. While the distal end of the guide catheter remains disposed in the left ventricle, a first tissue anchor of an implant is deployed from the distal end of the guide catheter. Subsequently, the guide catheter is retracted while progressively exposing the implant. Subsequently, a second tissue anchor of the implant is anchored to a posterior annulus of a mitral valve of the heart by deploying at least part of the second anchor within a left atrium of the heart, such that the implant extends from the first tissue anchor, over an atrial side of a posterior leaflet of the mitral valve, and to the second tissue anchor. Other embodiments are also described.

  • Patent number: 11638654
    Abstract: The present embodiments provide systems and methods for treating a medical condition. In one embodiment, the system comprises a stent having proximal and distal regions, and further having a delivery state and an expanded state. A therapeutic agent is disposed on a segment of the stent. The stent is disposed around an exterior surface of a core assembly in the delivery state. A coupling assembly releasably secures the proximal region of the stent to the exterior surface of the core assembly. The coupling assembly secures the stent to the core assembly for a predetermined period while the stent is in the expanded state and during release of the therapeutic agent at a target site. The coupling assembly further enables the stent to be disengaged from the core assembly and deployed in a bodily passageway.

  • Patent number: 11583390
    Abstract: An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with one or more folds of the bellows extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes when the eye accommodates.
