Implantat (1) zur Modifikation der Gewebedeformation während der Knochenheilung zwischen zwei Knochenfragmenten (5;6), mit einem ersten, an ein erstes Knochenfragment (5) befestigbares Endstück (2) mit einer Längsachse L1 und einem zweiten, an ein zweites Knochenfragment (6) befestigbares Endstück (3) mit einer Längsachse L2, wobei das erste und zweite Endstück (2;3) mittels je n ≥ 1 parallelgeschalteten Gewebe-Aktivatoren (4a;4b) miteinander lose im Eingriff stehen und eine Relativbewegung zulassen und die Gewebe-Aktivatoren (4a;4b) quer zu den Längsachsen L1 und L2 und vorzugsweise orthogonal dazu angeordnet sind.
摘要:
Bone-mimetic microstructures are formed within the paper scaffolds. Centimeter scale paper origami scaffolds are seeded with osteoblasts and cultured to induce formation of mineral deposits. The paper-based platform is a promising system to study mechanisms of biomineralization, repair mineralized tissues, understand healing and regeneration of bone, develop therapeutic approaches when mineralization is impaired, and understand the fundamental processes in biomineralization events.
摘要:
Embodiments of the invention described herein thus provide implants and methods for manufacturing an implant having an outer cortical layer that is porous. The porous outer cortical layer can help encourage tissue ingrowth into the implant. The porous outer cortical layer may be positioned around a core structure this is solid or that has a hollow interior. The core structure may be spherical or any other appropriate shape for a medical implant.

Vorverbundene mehrschichtige Folie (1) zur Abdeckung einer Knochendefektstelle (2), insbesondere im Bereich eines Kieferknochens, wobei die Folie (1) eine formgebende Formschicht (3) zur Anformung der Folie (1) an die Knochendefektstelle (2) und wenigstens eine Deckschicht (4, 4a, 4b) zur Abdeckung der Knochendefektstelle (2) umfasst, wobei die Formschicht (3) und die wenigstens eine Deckschicht (4, 4a, 4b) im Wesentlichen vollständig resorbierbar sind.
摘要:
An adjustable implant (10, 60, 70, 80, 90) has a base (12) and a displaceable element (16) providing opposing tissue contact surfaces (14, 18). A linkage (20, 26) is pivotally connected to the displaceable element. A linkage mover (38, 40), engaged so as to be displaceable along the base, is associated with the linkage (20, 26) so as to define a displaceable pivot location (24, 30) for pivotal motion of the linkage relative to the base. In certain preferred embodiments, the base (12) has an internally threaded track (42, 44) in which a threaded segment of the linkage mover (38, 40) is engaged, so that rotation of the threaded segment about its central axis advances the linkage mover along the threaded track, thereby displacing the displaceable pivot locations and adjusting a separation between the first contact surface and at least part of the second contact surface.
摘要:
The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. The fusion device is capable of being deployed down an endoscopic tube.
摘要:
An expandable intervertebral implant includes a base body, a top endplate and a center component. The top endplate is configured to be placed onto an open top of the base body and to expand upward. The top endplate includes a plate, first and second side protrusions extending vertically downward from first and second sides of the plate, respectively, first and second protrusions including inclined surfaces and extending obliquely downward from a first end of the plate and third and fourth protrusions having a triangular shape with at least one inclined surface and extending downward from a second end of the plate. The center component is configured to be placed within the base body and to interface with the top endplate and to move longitudinally forward or backward within the base body, thereby causing the top endplate to expand upwards or move downward, respectively.
摘要:
This invention provides novel synthetic bone grafting materials or tissue engineering scaffolds with desired structural and biological properties ( e.g. , well-controlled macroporosities, spatially defined biological microenvironment, good handling characteristics, self-anchoring capabilities and shape memory properties) and methods of their applications in vivo .
摘要:
A surgical implant includes a rod or guide, initially deployed to the surgical site, over which segments are deployed, typically by sliding and advancing the segments along or over the rod or guide. The rod is typically of a predefined curvature, which defines the shape of the implant. The rod deflects or orients into this predefined curvature upon its deployment at the surgical site. A portion of the rod with the segments remains at the surgical site after the requisite procedure is performed.
