  • Publication number: 20030078242
    Abstract: The present invention provides novel broad spectrum antiseptic compounds that further have properties that allow them to be coated/impregnated into polymer surfaces. Methods for coating these antiseptic compounds onto medical devices especially in-dwelling medical devices to prevent the growth of pathogens in such devices and hence, to prevent infection to patients via such devices are provided. The invention also provides antiseptics that are useful as general surface disinfectants and sterilizers, fluid disinfectants and biocide preservatives.

  • Patent number: 5902283
    Abstract: A non-metallic antimicrobial impregnated medical implant, such as a catheter, and a method for impregnating a non-metallic medical implant with an antimicrobial agent is provided. The method for making the impregnated implant comprises the steps of forming an antimicrobial composition of an effective concentration to inhibit the growth of organisms, such as staphylococci, other gram-positive bacteria, gram-negative bacilli and Candida and applying the antimicrobial composition to at least a portion of the medical implant under conditions where the antimicrobial composition permeates the material of the medical implant. The antimicrobial composition is formed by dissolving an antimicrobial agent in an organic solvent, adding a penetrating agent to the composition, and adding an alkalinizing agent to the composition. The antimicrobial composition is preferably heated to a temperature between about 30.degree. C. and 70.degree. C.

  • Patent number: 5820607
    Abstract: The present invention relates generally to indwelling medical devices. In particular, there is provided a device constructed from permeable or nonpermeable material having a pharmacologically active ingredient layer surrounding the device, and an outer sheath which is permeable to the pharmacologically active ingredient. This construction provides a device that allows the pharmacologically active ingredient located between the catheter tube and the outer sheath to slowly diffuse through the outer sheath and/or inner tube, thus inhibiting microbial infection on the outer surface and lumen of the catheter.

  • Patent number: 5362754
    Abstract: Disclosed are pharmaceutical compositions of a mixture of minocycline and EDTA (M-EDTA) and methods of using the compositions in maintaining the patency of a catheter port. Methods for inhibiting the formation of polysaccharide-rich glycocalyx (such as the glycocalyx of staphylococcal organisms) are also provided using an M-EDTA solution. The M-EDTA solution may also be used to pretreat a medical device to prevent adherence of infectious organisms, such as S. epidermidis and S. aureus. The compositions destroy and prevent the formation of polysaccharide-rich glycocalyx. Methods for treating infections of S. epidermidis and S. aureus where glycocalyx formation are provided with an M-EDTA solution. The minocycline and EDTA solutions are included together within a pharmacologically acceptable carrier solution, such as saline.
