  • Patent number: 11752019
    Abstract: A medical device such as a stent or medical balloon is functionalised prior to coating with a bioactive material, specifically by carboxylic acidification of the contact surface or surfaces of the medical device. The preferred process involves washing a stent or other medical device in a washing solution which may be sodium hydroxide, soaking in a carboxylic acid solution, rinsing in water to remove excess carboxylic acid, allowing to dry before applying a bioactive agent layer. It has been found that washing after functionalisation removes excess carboxylic acid and enhances the retention of bioactive agent on the contact surface or surfaces of the medical device leading to a more uniform and consistent layer of bioactive agent.

  • Patent number: 11754502
    Abstract: A method of increasing a surface-enhanced Raman scattering (SERS) signal of a compound is provided. The method includes dissolving the compound in water to form a solution, adding a substrate at least partially coated with gold nanoparticles to the solution to form a mixture, removing the substrate from the mixture and washing with water to form a SERS sample having at least a portion of molecules of the compound adsorbed to the gold nanoparticles on the substrate, and recording a SERS spectrum of the SERS sample. The gold nanoparticles are in a two-dimensional (2D) monolayer assembly on the substrate and are 10-250 nm in size. The SERS signal of the SERS spectrum is higher than a SERS signal of a SERS spectrum of the compound on the substrate without the gold nanoparticles.

  • Patent number: 11738122
    Abstract: Methods for improving the antibacterial characteristics of biomedical implants and related implants manufactured according to such methods. In some implementations, a biomedical implant comprising a silicon nitride ceramic material may be subjected to a surface roughening treatment so as to increase a surface roughness of at least a portion of the biomedical implant to a roughness profile having an arithmetic average of at least about 500 nm Ra. In some implementations, a coating may be applied to a biomedical implant. Such a coating may comprise a silicon nitride ceramic material, and may be applied instead of, or in addition to, the surface roughening treatment process.

  • Patent number: 11684948
    Abstract: A spray coating machine and process accommodates coating pans of various sizes and simplifies cleaning after particulate material in the pan is coated. A selected pan is supported on a trolley carried by a wheeled cart. After the cart is positioned adjacent the coating machine, the trolley and pan are extended into the machine, and then the pan lifted for support by a rotatable drive shaft and castors. The trolley is then removed from the machine, and the door is closed so that the coating process can commence. When coating is complete, the door is opened, and the trolley extended into the machine under the pan and raised for removal of the castors. Then, the trolley and pan are withdrawn from the machine. The trolley does not need cleaning after spraying, since the trolley is outside the machine during spraying of the coating solution.

  • Patent number: 11672992
    Abstract: A valve for use in manufacturing of implantable medical devices is insertable into a bore of the medical device during a manufacturing process. The valve is configured to remain closed while the pressure differential between an internal volume of the implantable medical device and a surrounding environment is below a particular threshold and to open when the threshold is reached, thereby allowing air or other fluids to escape from the internal volume into the surrounding environment. The valves are particularly useful during certain types of coating processes that must be performed at or near vacuum and provide an effective way to prevent ingress of coating material into the internal volume of the implantable medical device.

  • Patent number: 11617813
    Abstract: 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.
