  • Publication number: 20230338617
    Abstract: Methods and compositions for the biological repair of cartilage using a hybrid construct combining both an inert structure and living core are described. The inert structure is intended to act not only as a delivery system to feed and grow a living core component, but also as an inducer of cell differentiation. The inert structure comprises concentric internal and external and inflatable/expandable balloon-like bio-polymers. The living core comprises the cell-matrix construct comprised of HDFs, for example, seeded in a scaffold. The method comprises surgically removing a damaged cartilage from a patient and inserting the hybrid construct into the cavity generated after the foregoing surgical intervention. The balloons of the inert structure are successively inflated within the target area, such as a joint, for example. Also disclosed herein are methods for growing and differentiating human fibroblasts into chondrocyte-like cells via mechanical strain.

  • Patent number: 10045804
    Abstract: An anchoring device and method for attaching an object to a bone comprises an anchoring member having proximal and distal ends, with the proximal end being adapted to hold the object to the bone while the distal end is in the bone, and a locking member having proximal and distal ends, with the proximal end adapted to secure the anchoring member into the bone and oppose its pull-out or loosening by stopping its backing or preventing its unscrewing while the distal end is in the bone. Also provided are first and second fasteners, with the first fastener adapted to fit to the proximal end of the anchoring member, and the second fastener adapted to fit to the proximal end of the locking member. The end of the second fastener can have an angle that matches an angle of the locking member.

  • Patent number: 8827944
    Abstract: A novel ventricular catheter designed to reduce CSF shunt obstruction is disclosed comprising a tip using a membrane without any opening and capable of filtering the CSF. When the CSF flows through the membrane, neither tissue (choroid plexus, blood cells, tumor cells, suctioned ependymal tissue) nor proteins can break through the membrane, making this ventricular catheter capable of preventing obstruction from tissue invasion but also preventing clogging from protein precipitation, coagulation or flocculation along the downstream shunt system.

  • Publication number: 20130315908
    Abstract: The present invention generally concerns the detection and/or treatment of aneurysm in a non-invasive manner. In particular cases, the invention concerns methods and compositions for localizing a labeled composition to the site of an aneurysm for its detection and, in further cases, treatment of the aneurysm. In specific cases, the composition targets a subendothelial component of the aneurysmal wall, such as a smooth muscle cell exposed at the luminal surface of the vessel. In further specific cases, the composition targets an integrin receptor or laminin.

  • Publication number: 20130315936
    Abstract: Described herein is a method for non-invasive detection and treatment of intra-cranial aneurysms. Antibodies are provided to specifically react/bind with antigens of the cerebral aneurism wall. The antibodies may be bound to a label and/or to a therapeutic agent for diagnosis and/or for treatment purposes thereof. Intra-cranial aneurysms are thus non-invasively detected before rupture occurs and are specifically treated.
