  • Patent number: 11957587
    Abstract: A heart valve sizer and sizer cover are provided for determining the size of a heart valve annulus. The valve sizer can include a handle, a shaft extending distally from the handle, a sizing element coupled to the distal end of the shaft, the sizing element being movable between a first retracted position and a second expanded position, and a sizer cover. The sizer cover can be formed from a continuous sheet of material configured to surround at least a portion of the sizing element of the heart valve sizer so as to guard against entanglement of the sizing element with structures of a human heart.

  • Publication number: 20240070418
    Abstract: A scanning method for multiple barcodes is applied in an electronic device. The electronic device loads a tag template, and the tag template has a plurality of detection zones each corresponding to a target barcode and a target barcode type. The electronic device captures a tag image with a plurality of barcode patterns to be detected, and each barcode pattern to be detected has coordinate information on an image coordinate system. The electronic device overlays the tag image with the tag template to determine whether each barcode pattern to be detected is located in one of the detection zones. When the barcode pattern to be detected is located in one of the detection zones and matches the corresponding target barcode type, the electronic device reads the barcode pattern to be detected to obtain a read result.

  • Publication number: 20230382085
    Abstract: An electronic device may have optical components that each have first and second transparent layers such as first and second glass layers. The glass layers may have outer surfaces that face away from each other and inner surfaces that face towards each other. A polymer layer is formed between the inner surfaces of the glass layers. Along the periphery of each optical component, a hermetic seal is formed to protect the polymer material of the polymer layer. The seal may have a moisture barrier layer that is attached to the first and second glass layers. The moisture barrier layer may be supported by an elastomeric buffer member. The moisture barrier layer may be formed from metal film or a polymer layer or other substrate that is coated with a moisture-impermeable coating. The moisture-impermeable coating may be formed from one or more thin-film metal layers and/or one more thin-film dielectric layers.

  • 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.

  • Publication number: 20230125047
    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%.

  • Patent number: 11622861
    Abstract: Compressible heart valve annulus sizing templates suitable for minimally-invasive or otherwise reduced accessibility surgeries. The sizing templates may be folded, rolled, or otherwise compressed into a reduced configuration for passage through an access tube or other such access channel. Once expelled from the access tube the sizing templates expand to their original shape for use in sizing the annulus. The templates may be formed of an elastomeric polymer material such as silicone, a highly elastic metal such as NITINOL, or both. Grasping tabs or connectors for handles permit manipulation from outside the body. A NITINOL wireform may be compressed for passage through an access tube and expelled from the distal end thereof into a cloth cover to assume a sizer shape.
