A textile-based plate implant (and related methods) that supports tissue ingrowth within the implanted implant structure and is suitable for use in a variety of surgical applications, including but not limited to anterior, posterior and lateral surgical approaches directed towards the lumbar, thoracic and cervical regions of the spine.

Textile-based plate implant and related methods

A combination pre-filled and in situ filled implant for the replacement of an intervertebral disc of the spine, including a textile core and a flange with apertures dimensioned to receive screws or other affixation elements. The combination pre-filled and in situ filled implant may also have attached side pockets comprised of extra layers of embroidered fabric. The pockets on the implant may serve a dual purpose: to facilitate insertion and to expand the dimensions of the implant after insertion.

Textile-based surgical implant and related methods

A manufacturing process and resultant medical devices and components thereof wherein one or more individual laces () is placed within an embroidered structure () using an automated process allowing for the manufacture of embroidered surgical implants containing laces to be mass produced repeatably and cost effectively.

Embroidery using soluble thread

An embroidery process allowing for extra lengths of stitched thread pairs to be laid down in a zigzag pattern while embroidering on a dissolvable substrate such that when the substrate is removed, the extra length allows the two-dimensional embroidered structure to relax into a three-dimensional shape.

Using zigzags to create three-dimensional embroidered structures

An embroidery process allowing for a three-dimensional shape to be embroidered in two dimensions, allowing for the cost effective and repeatable manufacturing required for use in surgically implanted medical devices.

3-dimensional embroidery structures via tension shaping

A textile prosthesis comprising a unitary body of predetermined shape having structural integrity, the body including at least one anchorage body portion for attachment to an anatomical body part, the body being composed of a combination of binding yarns and tensile load bearing filaments, the binding yarns being located at least in the or in each of said anchorage body portions and being interconnected to one another by sewn stitches, the tensile load bearing filaments being located in between said stitches so as to be constrained to extend through said unitary body along predetermined pathways extending in one or more predetermined directions so as to render the body resistance to stretch when a tensile load is applied in said one or more predetermined directions.

A connector comprising at least one pair of apertures for receiving a fastener, such as a screw, a load bearing filament extending continuously along a predefined circuitous path which extends between and around each of the apertures of said pair of apertures. The load bearing filament extends around each aperture to define multiple aperture forming strands of said load bearing filaments. The multiple aperture forming strands of the load bearing filament are bound together around each aperture by binding filaments in order to constrain relative lateral movement between the aperture forming multiple strands and to define the shape of each aperture.

Connector

A graft is provided with a flexible sheet of graft material to which is sewn a reinforcing wire, preferably of shape-memory alloy. Sewing of the wire is carried out while the sheet is substantially planar, thus by conventional embroidery machines. The sheet is subsequently rolled into a tubular shape.

Reinforced graft

A tubular graft/stent comprises a tubular sheath having at intervals along its length a plurality of ring-like rigid members, which are attached to the sheath around their respective circumferences and are made of a shape memory material, so that when the members change shape the sheath adopts a new cross section in conformity with the members along the sheath's whole length. The members may be discontinuous to allow the adoption of a contracted shape in the martensitic phase and an expanded shape in the austenitic phase. A graft may also have a branched side tube which can be inverted so as to be housed within the sheath.
