Abstract: Aspects of the disclosure relate to prosthetic valves having a frame, a frame cover, and a leaflet construct. Some aspects are directed to a diametric taper for the prosthetic valve for achieving enhanced performance of the prosthetic valve under operational conditions, enhanced compressibility and delivery characteristics, and other additional or alternative advantages. Other aspects are directed toward unique assembly and attachment methods for securing leaflet constructs to support structures. Other aspects are directed toward features for interacting with transcatheter delivery systems. Still other aspects are directed to such apparatuses, systems, and methods for valve replacement, such as cardiac valve replacement.

Abstract: An implantable prosthetic valve has an upper frame section and a lower frame section. The upper frame section has a plurality of struts and a first leaflet receiving surface at a lower portion of the upper frame section. The lower frame section has a second leaflet receiving surface at an upper portion of the lower frame section. An edge of a flexible leaflet is disposed between the first and second leaflet receiving surfaces to attach the leaflet to the upper and lower frame sections.

Abstract: A spacer for creating a docking station for a transcatheter heart valve is provided. The spacer changes an effective diameter and/or a shape of an implanted bioprosthetic structure such as a bioprosthetic heart valve or annuloplasty ring, providing a supporting structure into which the transcatheter valve expands without over expanding. The spacer may be deployed through an interventional technique either through transseptal access, transfemoral access, or transapical access and is typically deployed at least in part on an inflow portion of the implanted bioprosthetic structure.

Abstract: A handle for a prosthetic heart valve delivery apparatus includes a housing, a motorized mechanism, and a holding mechanism. The housing is configured to be hand-held by a user and includes a distal opening. The motorized mechanism is disposed within the housing and is configured to be releasably coupled to a proximal end portion of a first shaft of the prosthetic heart valve delivery apparatus. When actuated, the motorized mechanism is configured to rotate the first shaft relative to the housing. The holding mechanism is disposed inside the housing and is configured to engage a proximal end portion of a second shaft of the prosthetic heart valve delivery apparatus such that the second shaft is axially and rotationally fixed relative to the housing, and the first shaft extends through the second shaft.

Abstract: Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

Abstract: The present invention relates to a stent (10) for the positioning and anchoring of a valvular prosthesis (100) in an implantation site in the heart of a patient. Specifically, the present invention relates to an expandable stent for an endoprosthesis used in the treatment of a narrowing of a cardiac valve and/or a cardiac valve insufficiency. So as to ensure that no longitudinal displacement of a valvular prosthesis (100) fastened to a stent (10) will occur relative the stent (10) in the implanted state of the stent (10), even given the peristaltic motion of the heart, the stent (10) according to the invention comprises at least one fastening portion (11) via which the valvular prosthesis (100) is connectable to the stent (10). The stent (10) further comprises positioning arches (15) and retaining arches (16), whereby at least one positioning arch (15) is connected to at least one retaining arch (16) via a first connecting land (17). The stent (10) moreover comprises at least one auxiliary retaining arch (18) which connects the respective arms (16′, 16″) of the at least one retaining arch (16) connected to the at least one positioning arch (15).

Abstract: A method of implanting a prosthetic heart valve within a patient can comprise inserting a distal end portion of a delivery apparatus and a prosthetic heart valve into the patient and advancing the prosthetic heart valve to a deployment location within the heart of the patient and inflating one or more of a plurality of differently-sized balloons in a balloon-assembly on the distal end portion of the delivery apparatus. The prosthetic heart valve can be mounted on the balloon assembly in a crimped state and the inflating of the one or more of the plurality of differently-sized balloons can expand the prosthetic heart valve from the crimped state to a radially expanded state having a non-cylindrical shape.
