The present invention is a self-cleaning catheter designed to impede the development of biofilm within the catheter and provide a mechanism for removing biofilm within the catheter during use by a patient. The self-cleaning catheter includes an outer shell enclosing a urine lumen. The urine lumen has the ability to be opened and closed with a urine lumen closure device and is formed with a plurality of micro ports and a plurality of macro wash ports. At least one antimicrobial lumen is affixed to the exterior of and in fluid communication with the urine lumen at the plurality of micro ports. Similarly, at least one wash lumen is affixed to the exterior of and in fluid communication with the urine lumen at the plurality of macro wash ports. Antimicrobial solutions and wash solutions are introduced into the urine lumen by the antimicrobial lumen and wash lumen respectively, even during use.

A radiographic imaging apparatus includes a radiation detector configured to convert incident radiation into an electric signal related to a radiographic image, a casing containing the radiation detector, and an antibacterial layer formed on at least part of a surface of the casing. An average thickness of the antibacterial layer is thicker than 0.05 μm and thinner than 0.5 μm.

A system, method, and article for delivering an antimicrobial agent into the lumen of a trans-dermal catheter are disclosed. In an embodiment, the system comprises an elongate member configured for insertion into a lumen of a catheter, and the elongate member containing an antimicrobial. In the alternative an antimicrobial agent can be placed on an interior surface of a retaining ring.

An anchor system for anchoring an umbilical catheter to an umbilical cord. The system has a vascular anchor element and an anchor clamp. The vascular anchor element has a duct configured to accommodate a portion of an umbilical catheter, and an end configured to be inserted into a blood vessel of the umbilical cord. The anchor clamp is configured to releasably retain at least one portion of the umbilical cord and at least one portion of the anchor element. The clamp has a slit configured to receive the at least one portion of the umbilical cord and the at least one portion of the anchor element; and a releasable locking system for selectively opening/closing the anchor clamp.

A catheter configured for partial implantation into a patient and drainage of a body cavity may be provided with microtextured surface on one or more inner diameter surfaces and/or outer diameter surfaces of the tubular catheter body. The microtexturing may include surface features dimensioned to inhibit colonization and/or migration of microbes. The microtexturing may also include channels or other recesses containing an antimicrobial agent such as chlorhexidine gluconate or any other effective antimicrobial agent.

Invasive medical devices including a substantially non-eluting antimicrobial treatment are disclosed. One or more external and/or internal surfaces of the medical device include a substantially non-eluting copper-coated surface that assists in preventing microbial colonization of the coated surface. This in turn reduces the incidence of infection to the patient originating from the medical device. In one embodiment, a catheter assembly is disclosed and comprises an elongate catheter tube that defines at least one lumen, at least one extension leg including a luer connector, and a bifurcation hub including at least one fluid passageway that provides fluid communication between the extension leg and the lumen. A substantially non-eluting copper coating is disposed on a surface of at least one of the lumen, the extension leg, the luer connector, and the fluid passageway. The coating is applied via an electroless deposition process. A water-shed coating is disposed on the copper coating.

A catheter assembly (1) includes an inner member (12) having a proximal end (15), a distal end (13), and a lumen configured to store a hydrating fluid (28) An outer member (10) has a proximal end (19), a distal end (16), and a lumen configured to receive therein a portion of the inner member (12) The outer member (10) is movable relative to the inner member (12) at least one of, between a first position (FIG. 1) preventing fluid (28) from passing out of the at least one drainage opening (14) from within the lumen of the inner member (12) and a second position (FIG. 2) allowing fluid (28) to pass out of the at least one drainage opening (14) from within the lumen of the inner member (12).

An antimicrobial lubricant applied to an outer surface of an introducer needle as part of a catheter assembly device. The catheter assembly device further includes a blood control septum having a slit through which the introducer needle is threaded. The antimicrobial lubricant is squeegeed, or removed from the outer surface of the introducer needle as the needle is removed from the slit following catheterization. The removed antimicrobial lubricant forms a deposit on the septum at a location proximate to the slit, thereby preventing colonization and growth of pathogens on the septum and other adjacent components and surfaces of the catheter assembly device.

An obturator can include antimicrobial features which assist in sterilizing or maintaining the sterility of fluid contained within a vascular access device while the device is not being used for infusion or other access to the patient's vasculature. These antimicrobial features include antimicrobial coatings applied to various surfaces of an obturator and antimicrobial components bonded or otherwise secured to an obturator. Various combinations of antimicrobial coatings and/or components can be used on an obturator as necessary to provide a desired amount of antimicrobial agents within a particular enclosed volume of a vascular access device.

A Sodium Bicarbonate Catheter Lock Solution that prevents clot formation inside the catheter lumen and ensures patency of the catheter and also eliminates bleeding and other complications caused through the use of anticoagulants and other solutions as a catheter locking solution. Said lock solution may be used with or without other components such as antimicrobials/antibiotics and/or anti-coagulants/anti-clotting agents.
