COMPOSTIONS AND METHODS FOR TISSUE REPAIR

Provided herein are compositions and methods for treating a subject with damaged tissue, such as an injury associated with a tissue to tissue (e.g., a connective tissue-to-connective tissue or tissue to bone) interface. One aspect provides an adhesive film or adhesive layer, optionally comprising a biomaterial, tissue growth factors, including CTGF/CCN2, or cells.

Small Diameter, High Strength, Low Elongation, Creep Resistant, Abrasion Resistant Braided Structure
20220372700 · 2022-11-24 ·

A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc.

Abradable therapeutic coatings and devices including such coatings

A method of reducing surgical site infection (SSI), using a coated medical device having a tissue penetrating surface and an abradable coating on the medical device comprising at least one antimicrobial agent in the coating.

INDIRECT ATTACHMENT OF A NEEDLE TO A MESH SUTURE
20220054127 · 2022-02-24 · ·

A medical device includes a surgical needle, an elongated suture, and an intervening segment. The elongated suture has a first end proximate to the needle and a second end located away from the needle. The elongated suture also includes a plurality of fibers defining a mesh wall between the first and second ends. A plurality of pores extend through the mesh wall, at least some which are in the macroporous size range of greater than 200 microns for facilitating tissue integration when introduced into a body. The intervening segment is disposed between and connected to either or both ends of the elongated suture and the needle. The intervening segment includes one or more fibers of the plurality of fibers and has a cross-sectional dimension smaller than a cross-sectional dimension of the mesh wall such that the intervening segment facilitates indirect attachment of the elongated macroporous mesh suture to the needle.

Biomaterial for suturing

A biomaterial for suturing comprising a physiologically compatible support material coated with a cellular population with proliferative and/or differentiation capacity, characteristics which facilitate the regeneration of the sutured tissue. This biomaterial for suturing not only brings together the two edges of an open wound, but also contributes actively to the healing process, thereby accelerating the tissue repair process. Also disclosed are methods for making the biomaterial and methods for using the biomaterials in therapy.

More particularly, the present disclosure relates to compositions including N-Acetylcysteine and an aminoquinoline. The present disclosure also relates to compositions including an endonuclease and an aminoquinoline. The present disclosure also relates to medical devices including a coating comprising N-Acetylcysteine, an aminoquinoline, an endonuclease, and combinations thereof.

Use for peptide uniquely binding to vascular endothelial cells, and peptide

Provided is a use for a peptide in surface-treating a medical device or medical material to be used in contact with blood, with which it is possible to obtain a medical device or medical material that can achieve highly efficient vascular endothelialization through the use of a peptide uniquely binding to vascular endothelial cells. Also provided are: a peptide suitable for use in said surface treatment; a method for producing a medical device or medical material surfaced-treated with said peptide and to be used in contact with blood; and a surface treatment agent including said peptide, said agent to be used in surface-treating a medical device or medical material to be used in contact with blood. In the present invention, a medical device or medical material is surface-treated using a peptide that includes any one of ten specific amino acid sequences and uniquely binds to the surface of endothelial progenitor cells.

Antimicrobial coatings for medical devices and processes for preparing such coatings

Antimicrobial formulations and coatings for medical devices and processes therefor are disclosed. The formulations include at least one water permeable polymer with at least one antimicrobial agent in a liquid medium and are prepared by wet milling the components and can form antimicrobial coatings having uniformly dispersed particles having an average size of no greater than 50 microns.

FULLY-THREADED BIOABSORBABLE SUTURE ANCHOR
20170231618 · 2017-08-17 ·

A suture anchor includes a threaded anchor body having a first central bore in communication with a second central bore. The suture anchor includes an internal eyelet formed of a loop disposed at least partially inside the first central bore. The ends extending from the loop are tied together to form at least one knot which is housed in the second central bore provided at the distal end of the anchor body. The knot increases the pullout strength of the suture even in soft bone, provides increased suture fixation, and eliminates the anchor “pull back.”

THREAD AND METHOD FOR PREPARING SAME
20220305177 · 2022-09-29 ·

This method for preparing a thread has a step for obtaining a thread-shaped vitrigel by wetting a first sheet-shaped hydrogel dried body or a sheet-shaped vitrigel dried body in a first aqueous solution and twisting the same into a thread shape.
