  • Patent number: 11911504
    Abstract: A device for protecting neurons and reducing inflammation and adhesion formation following surgery is provided. Also provided is a method for protecting neurons and reducing inflammation and adhesion formation following surgery. The device includes a bioabsorbable substrate and a layer of an oxidation inhibitor mimicking the effects of superoxide dismutase and catalase enzymes located on a surface of the substrate. Oxidation inhibitors that may be used include EUK-8, EUK-134, EUK-189, and EUK-207 (a mimetic of superoxide dismutase/catalase), monosodium luminol or phenyl N-t-butylnitrone or an analog with similar anti-oxidant properties. The oxidation inhibitors reduce oxidative stress and trigger the subject's natural anti-oxidant and anti-inflammatory defenses, thereby reducing neuron death, loss of neuron connectivity, inflammation and scarring and restoring excitatory function of neurons.

  • Patent number: 11911040
    Abstract: An embolic device for treating aneurysms or other vascular disorders may be more compliant than conventional devices, while still achieving desired porosity. In particular, the device may achieve the desired porosity only at discrete sections along the length of the device where such a porosity is required (e.g., sections that will block the neck of the aneurysm upon deployment). The remaining sections of the device can be configured to increase the device's compliance. For example, the remaining sections can be formed from less material than the sections with the desired porosity. In some instances, the sections with the desired porosity are formed from mesh-screen segments and the remaining sections are formed from coil segments. In some instances, the mesh-screen segments are configured to further enhance the device's compliance. For example, the mesh-screen segment can be formed from a layered structure that achieves greater compliance than conventional braided structures.

  • Patent number: 11864919
    Abstract: A flexible, passive pressure sensor includes three LC tank circuits. The first LC tank circuit is a pressure sensing LC tank circuit, having a capacitance that varies in response to changes in environmental pressure. The second and third LC tank circuits are reference LC tank circuits, having capacitances that are relatively constant over changes in environmental pressure. A measurement tool measures the resonant frequencies of the three LC tank circuits and then computes a pressure measurement that accounts for changes in resonant frequencies in the LC tank circuits due to environmental effects and deforming.

  • Patent number: 11628077
    Abstract: Post deployment radial force recovery of biodegradable scaffolds are described where a high molecular weight polymer may be formed into a high molecular weight scaffold by solution casting into a tubular substrate such that the scaffold retains its mechanical properties through processing. The tubular substrate is laser cut and subsequently crimped onto a catheter for deployment into a body lumen. The polymeric scaffold may retain its mechanical properties and result in increased radial strength post-deployment in a saline environment, e.g., within a body lumen. This scaffold enhancement may be attributable at least in part to entanglement of high molecular weight polymer chains as one factor that effects radial force recovery and also to the design or geometry of the scaffold as another factor that effects radial force recovery after deployment.

    Abstract: A coronary stent is disclosed herein as having a lattice configuration on a generally thin-walled cylindrical tube. This particular stent is fabricated using an elongated thin-walled tubular solid that has a diameter equal to that of the final expanded configuration of the stent. In other words, the lattice configuration is cut onto the surface of the tubular solid that has a diameter substantially equal to the inner diameter of the blood vessel for which the stent is intended. The tubular lattice is then shrunk (collapsed) axisymmetrically to a new cylindrical configuration with a diameter substantially less than the blood vessel for which the stent is intended. The stent in its reduced diameter state can then be delivered to a desired site in the body via a catheter with an inflatable balloon at its distal portion. Upon the inflation of the balloon, the stent will assume its expanded, deployed configuration into the original diameter at the desired site in the body.

PCD is harder than ceramic zirconia and harder than titanium. Because PCD is pure carbon, it is also 100% compatible with carbon-based living tissue. Unlike titanium, it does not provoke an immune response. PCD implants readily integrate into human jawbone. This drastically reduces post-surgery bone loss.

  • Patent number: 11439523
    Abstract: A stent having an improved anti-sliding function is proposed. The stent includes an inner stent and a pair of outer stents that have undergone heat treatment and have several spaces formed by weaving or crossing wires made of a superelastic shape memory alloy in a hollow cylindrical net shape, in which each of the outer stents is shorter than the inner stent and has an enlarged section having a diameter larger than the inner stent and a bending section formed by bending inward a side of the enlarged section; and the pair of outer stents are fitted on both ends of the inner stent such that the enlarged sections of the outer stents face each other, and spaces of the inner stent and spaces of the bending sections of the outer stents are connected by a connection thread, whereby a space section is defined between the inner stent and the outer stents.

  • Patent number: 11406519
    Abstract: An aneurysm bridging device can be placed in the neurovasculature of a patient by advancing the aneurysm bridging device in a small-diameter configuration a delivery catheter to a target region within the neurovasculature and securing the distal region of the aneurysm bridging device to the neurovasculature. While the distal region of the aneurysm bridging device is secured to the neurovasculature, the proximal region of the aneurysm bridging device can be advanced to permit the aneurysm bridging device to expand from the small-diameter configuration and to deform and twist in a central region of the aneurysm bridging device. The proximal region of the aneurysm bridging device can be secured within the neurovasculature to maintain the central region of the aneurysm bridging device in a deformed state.

  • Patent number: 11395736
    Abstract: A prosthetic heart valve including a stent frame and a valve structure. The valve structure is disposed within a lumen of the stent frame. The stent frame is configured to self-expand from a compressed condition for transluminal delivery. The stent frame has a lattice structure forming a tubular shape defining a circumference and a plurality of closed cells arranged to define a band exhibiting a variable radial stiffness. The prosthesis can be deployed such that the band applies a minimal force on to anatomical locations relating to the heart's conductive pathways. A region of the band otherwise having low radial stiffness is located at or over a conductive pathway upon final implant.

  • 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.
