Implantable Prosthesis Patents (Class 623/11.11)
  • Patent number: 11950993
    Abstract: In the field of medicine and medical technology, improving the technical properties of endoprostheses used for the surgical treatment of hernias. A self-expanding mesh endoprosthesis for endoscopic hernioplasty includes a mesh fabric made of threads and a self-expanding system incorporated in the mesh fabric, wherein the self-expanding system is made of polyfilament titanium threads located both in the structure and along the contour of the endoprosthesis, and wherein the titanium threads of the mesh fabric are made with a relief surface. The technical result increases efficiency of performing laparoscopic hernioplasty operations, increasing the plasticity, and reducing the risk of breakage of the threads in the mesh structure, simplifying the surgical technique for passing through and placement of the endoprosthesis, reducing the duration and trauma of surgery and, accordingly, accelerating the recovery of patients.

  • Patent number: 10092409
    Abstract: A device and method of manufacturing and implanting a custom subtalar arthroereisis implant having side surfaces which are mirrored in topography with the sinus tarsi of a patient. The implant is formed using images of the patient standing in a weight bearing position with their sinus tarsi and the surrounding bone structure in an anatomically correct alignment. Once implanted, the implant urges and maintains the anatomically correct alignment thereby minimizing any patient tendency for abnormal motion between said patent's talus and calcaneus.

  • Patent number: 10052186
    Abstract: A prosthetic implant includes an anterior surface, configured for at least partial contact with an underside of a patient's facial soft tissue. A posterior surface is oppositely placed to the anterior surface. The posterior surface is configured for at least partial contact with a patient's facial bony tissue when the anterior surface is in at least partial contact with the patient's facial soft tissue. An implant body is defined by the anterior and posterior surfaces and extends transversely therebetween. A selected portion of the posterior surface has a texture that mechanically differs from a texture of a majority of the anterior surface.

  • Patent number: 10034373
    Abstract: An electronic device having a circuit board and a battery is disclosed. The circuit board may include a through hole and an electrical pad surrounding the through hole. In order to electrically couple the circuit board to the battery, and in particular, an electrode of the battery, a tab (or plaque) is placed between the electrical pad and the electrode. The tab electrically couples with the electrical pad by a soldering operation. To couple (electrically and mechanically) the tab with the electrode, a welding operation is used. The welding operation may include a laser weld providing thermal energy through a laser beam. In this regard, the laser beam passes through the through hole, thereby (partially) melting the tab and forming a weld between the tab and the electrode. Accordingly, the tab covers the through hole such that the tab is positioned to receive the laser beam.

  • Patent number: 9848994
    Abstract: The present application generally relates to orthopedic systems, and in particular, to systems including independent plates and spacers. A plating system can include a spacer and a plate that is independent from the spacer. A number of locking mechanisms can be provided to secure the plate to the spacer. In some cases, the spacer includes a pair of notches that extend on an outer surface of the spacer. The plate can include a pair of lateral extensions that can engage the notches to secure the plate to the spacer. In other cases, the spacer includes an opening including a pair of inlets. The plate can include an enclosed posterior extension that can be received in the pair of inlets to secure the plate to the spacer.

  • Patent number: 9782515
    Abstract: A method for treating an oral condition of a subject by grafting cultured tissue constructs to the oral tissue. The cultured tissue constructs comprise cultured cells and endogenously produced extracellular matrix components without the requirement of exogenous matrix components or network support or scaffold members. Some tissue constructs of the invention are comprised of multiple cell layers or more than one cell type. The tissue constructs of the invention have morphological features and functions similar to tissues their cells are derived and their strength makes them easily handleable. Preferred cultured tissue constructs of the invention comprise cells derived from human tissue.

    Abstract: A method and device for treating hernia by implanting at least one collapsible hernia repair patch, such as a planar mesh body at least partially enveloped by one or more elastic collars. A posterior end of an applicator carrying the repair patch may be inserted through a hernia and into the wall of the abdominal cavity, and the patch may be released into the cavity, e.g., so as to helically deploy the patch such that the patch lies in parallel to the abdominal wall. A balloon, which is removably attached to the patch, may be inflated to help move the patch to a deployed configuration, and thereafter the balloon removed from the hernia site.
