  • Patent number: 11395733
    Abstract: A method of sewing preserved animal tissue to a manmade work piece that forms a part of a prospective bioprosthetic heart valve. The method utilizes a needle having an attached suture length and also having a relative object visibility of less than 0.8 relative to a standard straight surgical needle. Also, this needle has a volume of less than 7 mm3 and a surface area of less than 70 mm2, is formed entirely of 300 series stainless steel, and has an eye, and the suture length is threaded through the eye. The needle having an attached suture length is used to manually sew the animal tissue to the manmade work piece that forms a part of the prospective bioprosthetic heart valve, while maintaining sufficient optical closeness to maintain the visibility of the needle.

  • Patent number: 11357617
    Abstract: Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.

  • Patent number: 11344439
    Abstract: Implantable stents that include strips that are each comprised of main struts connected by first connectors, and adjacent strips are connected by second connectors. The strut connectors have a structure, including areas of expanded or reduced width or thickness, to account for venous applications. When used for venous applications, the stents convey benefit from configurations that improve flexibility (due to the greater elasticity of venous applications) while maintaining enough stiffness to resist pressure on the venous structure in selected areas (such as for the May-Thurner syndrome). The stents include particular structural characteristics that are particularly advantageous for (although not limited to) venous applications.

  • Patent number: 11337800
    Abstract: The disclosure relates to heart valve prostheses with the reduced need of pacemaker implantation and improved means for positioning the replacement heart valve. In one aspect of the present disclosure, the stent scaffold of the valve prosthesis includes axially extending locators. The locators may be positioned within the cusp of the native aortic valve. Placement of the locators within the cusps may prevent further proximal movement of the stent scaffold into the left ventricle. By adjusting the location of the proximal end of the locators with respect to the proximal end of the stent scaffold, infra-annular placement of the stent scaffold in the aortic annulus may be assured. In another aspect, means for visualizing the positioning of replacement heart valves at an implant site inside an individual's body is disclosed.
