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
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.
Antimicrobial-containing silicone lubricious coatings
Novel, lubricious antimicrobial coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes at low temperatures that do not deform the device and preserves the antimicrobial effectiveness of the antimicrobial agent. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.
Method for preparing high-functional suture yarn coated with hyaluronate and high-functional suture yarn prepared therefrom
Provided is a method of manufacturing a hyaluronate-coated high-functional suture and a high-functional suture manufactured thereby, and more particularly to a method of manufacturing a high-functional suture and a high-functional suture manufactured thereby, wherein a suture for internal and external surgery derived from a conventional chemical synthetic material is coated with a hyaluronate as a biocompatible material, thus improving biocompatibility, functionality and ease of use. Upon application of the hyaluronate-coated suture of the invention to the human body, the hyaluronate applied on the surface of the suture is rapidly swollen by body fluids and can thus function as a lubricant, thus being convenient to use by a surgical doctor and reducing the pain of a patient and maximizing the functions of skin filling or skin regeneration in the body.
Polytetrafluoroethylene co-polymer emulsions
The present disclosure is directed to a class of fluorinated copolymers, such as PTFE copolymers, that can be dissolved in low toxicity solvents, such as Class III Solvents, and that enable the creation of stable water-in-solvent emulsions comprising the fluorinated copolymers dissolved in a low toxicity solvents and a hydrophilic agent (e.g., a therapeutic agent) dissolved in an aqueous solvent, such as water or saline.
Fusible biodegradable sutures utilizing tissue soldering technology
This disclosure concerns suburethral and pelvic support structures which utilize tissue soldering materials instead of, or in addition to, traditional tissue anchors and suture knots. It further concerns methods of treating patients that includes implanting these structures and activating the tissue soldering materials to attach the structures to a tissue in the body of the patient.
Operating room coating applicator and method
The present disclosure provides a coating applicator operable to apply a coating of a therapeutic agent upon an object comprising an openable and sealable device compartment, a therapeutic agent positioned in communication with the device compartment, an atomizer operable to atomize the therapeutic agent, and a source of vacuum in communication with the device compartment. The coating applicator may further comprise a drier, and the drier may comprise an arrangement to operate the source of vacuum for a time sufficient to promote drying of applied therapeutic agent. Deposition of the atomized therapeutic agent may be promoted by contacting the atomized therapeutic agent while the object is in a chilled condition and by contacting the object with atomized therapeutic agent while the atomized therapeutic agent is in a heated condition. Related methods are also disclosed.
