COMPOSITE SCAFFOLD FOR THE REPAIR, RECONSTRUCTION, AND REGENERATION OF SOFT TISSUES

A composite scaffold having a highly porous interior with increased surface area and void volume is surrounded by a flexible support structure that substantially maintains its three-dimensional shape under tension and provides mechanical reinforcement during repair or reconstruction of soft tissue while simultaneously facilitating regeneration of functional tissue.

20220202988 · 2022-06-30 · ·

Resorbable implants comprising poly(butylene succinate) and copolymers thereof have been developed. The implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing, and the fibers may be oriented. Coverings and receptacles made from forms of poly(butylene succinate) and copolymers thereof have also been developed for use with cardiac rhythm management devices and other implantable devices. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings and receptacles are made from meshes, webs, lattices, non-wovens, films, fibers, and foams, and contain antibiotics such as rifampin and minocycline.

Compliance control stitching in substrate materials
11369464 · 2022-06-28 · ·

Compliance control stitch patterns sewn or embroidered into biotextile or medical textile substrates impart reinforcing strength, and stretch resistance and control into such substrates. Compliance control stitch patterns may be customizable to particular patients, substrate implantation sites, particular degenerative or diseased conditions, or desired time frames. Substrates having compliance control stitch patterns sewn or embroidered into them may be used in tissue repair or tissue reconstruction applications.

LIGATURE DELIVERY SYSTEM FOR AXIAL FIXATION OF PELVIC FLOOR STRUCTURES IN PELVIC ORGAN PROLAPSE AND STRESS URINARY INCONTINENCE REPAIR

The invention relates to medicine, in particular, to gynecology and urology, namely, to for ligature delivery system for axial fixation of pelvic floor structures in pelvic organ prolapse and stress urinary incontinence. Ligature delivery system for axial fixation of pelvic floor structures in pelvic organ prolapse and stress urinary incontinence consisting of the mesh material that is woven from a non-biodegradable and biodegradable monofilament threads, according to the invention so that non-biodegradable threads are arranged along to the implant axis and are not linked with each other. The technical effect is providing the axial support that is physiological for apical structures of pelvic floor and minimizing risks of mesh-associated postsurgical complications.

Prosthetic porous knit

The invention relates to a prosthetic porous knit based on a monofilament of a biocompatible polymer material, the pattern followed for the knitting of said monofilament on a warp knitting machine having two guide bars B1, B2 being the following, according to the ISO 11676 standard: Bar B1: 1.2/4.5/4.3/4.5/4.3/1.0/1.2/1.0// Bar B2: 4.3/1.0/1.2/1.0/1.2/4.5/4.3/4.5// The invention further relates to a method for producing such a knit and to a hernia prosthesis comprising such a knit.

Implantable mesh and method of use
11351022 · 2022-06-07 · ·

An implantable mesh for use in high tension tissue reconstruction includes a mesh body having a surrounding edge and at least two mesh extensions comprised of mesh and extending from the surrounding edge of the mesh body. Each mesh extension has a first end, a second end, and a length therebetween, the first end being integrated into or part of the mesh body. Each mesh extension is configured to be passed through tissue surrounding a reconstruction site to create multiple anchor points with the surrounding tissue upon implantation so as to resist high tension across the reconstruction site without dehiscing or migrating.

Corner-lock stitch patterns
11344397 · 2022-05-31 · ·

Stitching patterns overlap to produce a corner-locked stitch pattern. The corner-locked stitch pattern includes one or more thread interlace points, and one or more overlays of threads from overlapping patterns. A network of corner-lock stitch patterns produces a mesh, which may be embroidered into a substrate, such as a medical textile or biotextile. Corner-lock stitch patterns resist puncture-induced and tension-induced deformation of mesh pores between corner-locked stitch patterns, and may be used to modulate compliance and enhance strength properties of a substrate into which they are sewn.

SYNTHETIC PROSTHESIS COMPRISING A KNIT AND A NON POROUS FILM AND METHOD FOR FORMING SAME

The present invention relates to a synthetic prosthesis for tissue reinforcement comprising: a porous knit made from a monofilament of a synthetic biocompatible material, said knit defining two opposite faces, a first face and a second face, a synthetic non porous biodegradable film comprising at least a copolymer of at least ε-caprolactone, said film covering at least part of said first face, a synthetic biodegradable binder bonding said film to said first face, said binder comprising at least a polymer of ε-caprolactone, wherein said second face of said porous knit is left open to cell colonization. The invention also relates to a method for forming such a prosthesis.

MICROSTRUCTURE SOFT TISSUE GRAFT
20230263614 · 2023-08-24 ·

Soft tissue repair grafts are described comprising an anti-adhesion layer, a structural layer, and a localization layer. These layers may be distinct or integrated into one substrate. The term layer is used to distinguish tissue repair graft functionality rather than distinct material layers. The distinct layers of functionality may comprise a single plane of a substance.
