TECHNOLOGIES FOR FIBER NANOTECHNOLOGY

Technologies for fibers with nanotechnology is disclosed. In the illustrative embodiment, a preform is 3D printed with one or more sacrificial cores and one or more hollow channels. The preform is drawn into a fiber, and one or more metal core(s) is inserted into the hollow channel during the fiber draw. The fiber is then heated, breaking up the sacrificial cores into balls through capillary action. The fiber can be etched, exposing the balls made up of the sacrificial cores. The balls can be selectively etched, exposing the metal core(s) of the fiber. Additional embodiments are disclosed.

FIBERS OF POLYMERS THAT HAVE A BACKBONE INCLUDING A POSITIVELY CHARGED COMPONENT OF A ZWITTERIONIC MOIETY, AND THEIR USE IN IMPLANTABLE THERAPEUTIC DELIVERY SYSTEMS
20220380944 · 2022-12-01 ·

The present application relates to fibers having a diameter of 1 nm to 10,000 nm, of one or more biocompatible polymers, wherein the polymers have a backbone which includes a positively charged component from a zwitterionic moiety. Additionally, this application discloses an implantable therapeutic delivery system and its method of formation, comprising a housing defining a chamber, wherein said housing is porous and formed from the fibers. Inside of the housing includes a preparation of cells which release a therapeutic agent from the chamber. The implantable therapeutic delivery system can be used in the treatment of diabetes.

Layer by layer coated mesh for local release of bio-active proteins

The present invention relates to biomaterials coated with an active agent eluting coating, wherein implantation of the coated biomaterial results in reduced implant-related complications and/or improved integration of the biomaterial into the host tissue and further relates to kits containing the coated biomaterial. The present invention also relates to methods and kits for coating the biomaterial. It is based, at least in part, on the discovery that biomaterial coated with a cytokine eluting coating resulted in the shift of early stage macrophage polarization that were associated with positive long-term effects such as minimized capsule formation and improved tissue quality and composition as compared to uncoated biomaterials.

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.

SURGICAL SUTURE HAVING EXCELLENT BIOCOMPATIBILITY AND LOW FRICTION, AND METHOD FOR MANUFACTURING SAME

The present invention relates to a surgical suture having excellent biocompatibility and low friction, and to a method for manufacturing same. The suture according to the present invention has excellent biocompatibility and low friction, thereby reducing pain that may occur in a patient during suturing and minimizing the occurrence of inflammation in cells at a suture site, and also has excellent contact properties with cells, thereby capable of being used for various medical and surgical operations.

Sutures with External Filament Containing A Medicant
20220323636 · 2022-10-13 ·

The present invention is directed to suturing systems having a needle, an elongated flexible suture having a connecting end attached to a said needle and an opposing free end and at least one elongated external beneficial filament that is attached to said needle or attached to said suture at the connecting end. The beneficial filament has a smaller cross-sectional area and lower mechanical strength than the suture and contains a medicant.

SOLVATOCHROMIC INDICATOR FOR DETECTING INFECTION
20220323615 · 2022-10-13 ·

A solvatochromic indicator for detecting the presence of a bacterial infection is disclosed. An indicator consisting of Beta vulgaris and further optionally comprising Curcuma longa, isopropyl alcohol, and any combination thereof, undergoes a detectable color change in the presence of an infection. Further provided are filaments treated with the solvatochromic indicator wherein the detectable color change of the indicator is based on the pH of the tissues with a bacterial infection.
