  • Publication number: 20250090149
    Abstract: The present technology is directed to implantable medical devices, systems, and methods for restricting, closing, or blocking an opening or defect in an anatomical structure. For example, many embodiments of the present technology are directed to implantable closure devices for plugging or sealing an opening in an anatomical structure separating a first body region and the second body region. In many of the embodiments described herein, the implantable closure devices are designed to be “recrossable,” such that a catheter or other percutaneous tool can be passed through the closure device after the device has been implanted.

  • Publication number: 20240268688
    Abstract: The present technology is generally directed to medical systems having sensors and diaphragms. The sensor device can include a body having a diaphragm. The diaphragm can be formed, for example, by applying a force to the body to create an impression or pattern that corresponds to the diaphragm. The sensor device can be positioned at least partially within a body cavity, and the diaphragm can be configured to flex or bend in response to one or more physiological parameters in the body cavity. In some embodiments, the sensor device can include one or more sensor measurement components configured to measure the one or more physiological parameters based on the flexing or bending of the diaphragm.

  • Publication number: 20080091059
    Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial adjustability and retrievability years after implant. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize an adjustable bridge stop to secure the implant, and the methods of implantation employ various tools.

  • Publication number: 20080065204
    Abstract: An implant for supplementing, repairing, or replacing a native heart valve leaflet or leaflets provides a scaffold, which defines a pseudo-annulus. The implant further has at least two struts in generally oppositely spaced apart positions on the scaffold. The scaffold can be placed in an elastically loaded condition in a heart with the struts engaging tissue at or near the leaflet commissures of a heart valve annulus, to reshape the annulus for leaflet coaptation. The implant further provides a neoleaflet element coupled to the scaffold within pseudo-annulus, to provide a one-way valve function.

  • Publication number: 20070168020
    Abstract: A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening. The secondary stent section has an unexpanded configuration with a first length and an expanded configuration with a second length where the first length is less than the second length. The secondary stent section is expanded to the expanded configuration after the primary stent section is expanded to the expanded configuration. The secondary stent section forms a portion of the tubular wall of the primary stent section in the unexpanded configuration.

  • Publication number: 20060106456
    Abstract: Devices, systems, and methods employ an implant that is sized and configured to attach to the annulus of a dysfunctional heart valve annulus. In use, the implant extends across the major axis of the annulus above and/or along the valve annulus. The implant reshapes the major axis dimension and/or other surrounding anatomic structures. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets, which, in turn, reduces retrograde flow or regurgitation. The implant improves function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.

  • Publication number: 20060069430
    Abstract: Devices, systems and methods retain a native heart valve leaflet to prevent retrograde flow. The devices, systems, and methods employ an implant that, in use, rests adjacent a valve annulus and includes a retaining structure that is sized and shaped to overlay at least a portion of one or more native valve leaflets. The retaining structure retains the leaflet or leaflets it overlays, to resist leaflet eversion and/or prolapse. In this way, the implant prevents or reduces regurgitation. The implant does not interfere significantly with the opening of and blood flow through the leaflets during periods of antegrade flow.

  • Publication number: 20050267573
    Abstract: Devices, systems and methods supplement, repair, or replace a native heart valve. The devices, systems, and methods employ an implant that, in use, extends adjacent a valve annulus. The implant includes a mobile neoleaflet element that occupies the space of at least a portion of one native valve leaflet. The implant mimics the one-way valve function of a native leaflet, to resist or prevent retrograde flow. The implant restores normal coaptation of the leaflets to resist retrograde flow, thereby resisting eversion and/or prolapse, which, in turn, reduces regurgitation.

  • Publication number: 20050228468
    Abstract: Devices, systems and methods establish scaffold-like structures within the heart or a body cavity. The scaffold-like structures establish a stable platform that makes it possible to accomplish a desired therapeutic and/or diagnostic objective in a targeted fashion in one or more tissue regions. The desired therapeutic and/or diagnostic objectives can include, e.g., (i) the delivery of various chemical, drug, and/or biological agents (in liquid, gel, or wafer form) into contact on or in the tissue regions, to accomplish, e.g., ablation or other therapeutic objectives in a controlled, precise fashion; and/or (ii) the delivery of mechanical, heat, cooling, or electrical energy to the tissue region—e.g.
