  • Patent number: 9937041
    Abstract: A tricuspid remodeling annuloplasty ring having two free ends that are upturned in the inflow direction to help avoid unnecessary leaflet abrasion. The free ends are separated across a gap that is large enough to reduce the risk of passing sutures through the conductive system of the heart, yet not too large that support of the septal leaflet of the tricuspid annulus is degraded. The ring may have four sequential segments looking from the inflow side and extending in a clockwise direction from a free end located adjacent the antero septal commis sure after implant. The ring may define an inflow bulge in the first segment and/or an inflow bulge in the fourth segment that help the ring conform to the natural bulges created by the adjacent aorta, thereby reducing stress and the potential for ring dehiscence. Desirably, the ring has variable flexibility, either gradual and/or between or within different segments.

  • Publication number: 20170112576
    Abstract: Methods and apparatus for enhancing surgical planning provide enhanced planning of entry port placement and/or robot position for laparoscopic, robotic, and other minimally invasive surgery. Various embodiments may be used in robotic surgery systems to identify advantageous entry ports for multiple robotic surgical tools into a patient to access a surgical site. Generally, data such as imaging data is processed and used to create a model of a surgical site, which can then be used to select advantageous entry port sites for two or more surgical tools based on multiple criteria. Advantageous robot positioning may also be determined, based on the entry port locations and other factors. Validation and simulation may then be provided to ensure feasibility of the selected port placements and/or robot positions. Such methods, apparatus, and systems may also be used in non-surgical contexts, such as for robotic port placement in munitions diffusion or hazardous waste handling.

  • Patent number: 8728264
    Abstract: Disclosed is a method for producing a hemocompatible article. A non-thermally stabilized polytetrafluoroethylene membrane comprised of non-oriented fibers is heated to a temperature of around 400° C. and above the gel point of the polytetrafluoroethylene, while the membrane is being applied against a forming mold. The membrane is applied against the forming mold by generating a pressure differential between opposing faces of the membrane to form a conformed membrane. The conformed membrane is then cooled, thereby producing the hemocompatible article.

  • Patent number: 8034104
    Abstract: An anatomically approximate prosthetic heart valve includes dissimilar flexible leaflets, dissimilar commissures and/or a non-circular flow orifice. The heart valve may be implanted in the mitral position and have one larger leaflet oriented along the anterior aspect so as to mimic the natural anterior leaflet. Two other smaller leaflets extend around the posterior aspect of the valve. A basic structure providing peripheral support for the leaflets includes two taller commissures on both sides of the larger leaflet, with a third, smaller commissure between the other two leaflets. The larger leaflet may be thicker and/or stronger than the other two leaflets. The base structure defines a flow orifice intended to simulate the shape of the mitral annulus during the systolic phase. For example, the flow orifice may be elliptical.
