COMPOSITE SURGICAL SUTURE MATERIAL BASED ON POLYFILAMENTOUS TITANIUM THREAD AND BIORESORBABLE POLYMERS
In the field of medicine and medical technology, improving the technical properties of the surgical suture material. Composite surgical suture material includes titanium monothreads combined in a polyfilament thread, wherein a bioresorbable polymer material is present in the gaps between the monothreads and on their surface, and the monothreads have a relief surface. The technical result increases the strength, elasticity and plasticity of the suture material, the absence of a sawing effect on tissues, an increase in the sliding friction coefficient, and also in ensuring capability of carrying antibacterial and other medicinal substances in its structure, in ensuring a long-term presence in the body and possessing a high biological inertness in the late postoperative period, which excludes the initiation and persistence of aseptic inflammation associated with the presence of the material in the body.

HERNIA REPAIR, BREAST RECONSTRUCTION AND SLING DEVICES CONTAINING POLY(BUTYLENE SUCCINATE) AND COPOLYMERS THEREOF
Resorbable implants comprising poly(butylene succinate) and copolymers thereof have been developed. The implants 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.

Readily absorbable copolymer compositions for high strength sutures having enhanced strength retention post-implantation
Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.
High Tenacity Fibers
Medical grade yarns, medical devices constructed of such yarns, and methods for making such yarns and devices are described. Polyester drawn fibers, and more particularly high strength and high tenacity micro polyester fibers for use in medical devices, and methods of preparing the same are provided.

Reinforced graft constructs and methods of tissue repairs
Surgical constructs, assemblies and methods for tissue reinforcement with a reinforcement (reinforcing) material such as suture, tape, weave, ribbon or mesh, among many others. The reinforced construct includes a reinforced section that prevents a suture from pulling apart. The reinforced section is be a piece of material (a reinforcement or reinforcing material) such as reinforced stitched suture tape attached to a flexible strand. A needle attached to the flexible strand terminating with the reinforced section passes through a proximal end of the reinforced section to form an adjustable starter loop. The starter loop is slid and positioned over tissue (for example, graft, tendon, ligament, etc.) and the suture is pulled apart to tighten the loop around the tissue.
