  • Patent number: 12181740
    Abstract: A transparent structure may have layers with curved cross-sectional profiles. The transparent structure may have inner and outer layers with curved portions formed by bending the layers. A display may be applied to one or more of the inner and outer layers. To reduce the strain applied to the display while being bent into a desired curvature, a carrier film may be used during bending operations. The carrier film may be modified with a patch or openings distribute the strain evenly across the display. Additionally or alternatively, a convex mold may be used to further decrease the strain on the display while being formed into the desired curvature.

  • Patent number: 12167964
    Abstract: A minimally-invasive annuloplasty ring for implant at a mitral annulus. The annuloplasty ring has an inner core member with a C-shaped plan view that generally defines an oval with a major axis and a minor axis, and is symmetric about the minor axis. A posterior portion of the core member bisected by the minor axis has a thicker radial dimension than a pair of free end regions terminating on an anterior side of the core member. The radial thickness smoothly transitions between the posterior portion and the end regions. The inner core member may be covered with a fabric, and is a superelastic metal so that it can be straightened out and delivered through an access tube. The curvatures and thicknesses around the core member are selected so that the strain experienced when straightened does not exceed 7-8%.

  • Publication number: 20240238086
    Abstract: A holder for a hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a non-expandable, non-compressible prosthetic valve and a self-expandable anchoring stent, thereby enabling attachment to the annulus without sutures. A first suture connects the holder to the valve and constricts an inflow end of the anchoring stent. A second suture connects the holder to the valve and extends down three holder legs to loop through fabric on the valve. Both sutures may loop over a single cutting well on the holder so that severing the first and second sutures at the single cutting well simultaneously releases the tension in the first suture, permitting the inflow end of the anchoring stent to expand, and disconnects the valve holder from the prosthetic heart valve.

  • Publication number: 20240173034
    Abstract: Systems, apparatuses, and methods disclosed herein may be directed to clips for medical implementation, including clips for a portion of a heart. The clips may be configured to close the portion of the heart, to reduce blood flow therethrough as well as passage of clots or other undesired materials. In examples, the clips may be configured to close the left atrial appendage (LAA). The closure of the LAA may reduce the possibility of stroke or other maladies stemming from fluid flow with the LAA. In examples, the clips may be positioned exterior of the LAA, to extend over an outer surface of the LAA for closure.

  • Patent number: 11983370
    Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.

  • Publication number: 20230181320
    Abstract: A mitral repair annuloplasty ring that will accommodate implantation of a transcatheter valve therein for a valve-in-ring reoperation. The ring has a semi-rigid core with features that allow the ring to better conform to the cylindrical geometry of a transcatheter valve when implanted. The inner core defines a continuous peripheral D-shape with a substantially straight anterior side diametrically across from a more rounded posterior side with arcuate lateral sides therebetween. Segments of the ring core are subject to differing rates of bending due to variable radial thicknesses or radial slits opening to both inner and outer edges around the core periphery. One or more expansion joints may also be used to create the more circular final expanded shape. A plastically expandable sealing sleeve may surround the transcatheter valve for sealing gaps between the valve and annuloplasty ring.
