Abstract: A catheter-disinfecting system can include, in some embodiments, an introducer sheath and a germicidal irradiation means for irradiating a catheter tube of a catheter with germicidal radiation. The introducer sheath can include a sheath body configured to be percutaneously inserted into an insertion site of a patient. The germicidal irradiation means can be configured for irradiating the catheter tube as the catheter tube is inserted into a lumen of the introducer sheath, thereby disinfecting the catheter tube immediately before insertion into the insertion site. A method of disinfecting a catheter such as the foregoing catheter can include inserting the catheter tube into the introducer sheath while the introducer sheath, itself, is percutaneously inserted into the insertion site of the patient; and irradiating the catheter tube with the germicidal radiation while inserting the catheter tube into the introducer sheath.

Abstract: Disclosed herein are disinfection inserts comprising a fiber optic and a polymer surrounding at least a portion of the fiber optic (and methods of making and using the same). The polymer comprises a NO donor molecule that releases NO upon illumination of the polymer by the fiber optic. The disinfection inserts can be inserted into tubing, catheters, and/or extracorporeal devices and illuminated to release NO from the polymer. The released NO inactivates pathogens on or within the tubing, catheter, and/or extracorporeal device. The disinfection insert can be configured for removable attachment to the tubing, catheter, and/or extracorporeal device, such that it can be periodically replaced. Furthermore, the disinfection insert can be placed in optical communication with a controllable light source. The controllable light source can be coupled to a light source controller. The intensity and wavelength of the light can be varied to change the flux of NO.

Abstract: A dialysis sheath is used with a catheter that cleans clots from a synthetic blood vessel or fistula. The dialysis sheath comprises a main hollow body and a stop mechanism. The main body has a lower portion for insertion into the synthetic blood vessel or fistula. The stop mechanism is movable between (i) a first position in which the stop mechanism is adjacent to or within a surface of the main hollow body and (ii) a second position in which the stop mechanism radially protrudes from the main hollow body. The stop mechanism is configured to engage an inner surface of the synthetic blood vessel or fistula to maintain the lower portion of the dialysis sheath within the synthetic blood vessel or fistula when the dialysis sheath is moved to a different position. The stop mechanism can be fluid-actuated and include a balloon-like structure.

Abstract: A catheter housing device for securing a catheter and needle assembly to a patient. The device can include a cover, an IV/catheter lock, a hub, and one or more fastening straps. The device can replace conventional devices and techniques for securing a catheter and needle to a patient that utilize adhesive materials and/or methods, which are ill-equipped to solve complications including infection/contamination of the insertion site, irritation/damage to the vein or insertion site due to inappropriate angling of the catheter/needle, etc. The devices and methods disclosed herein can provide catheter/needle securement and optimal inclination, a hermetically sealed chamber to resist infection and/or contamination, inert gas or soothing anesthetic vapor drugs in and around the device, and various skin-contacting layers and structures that promote ventilation and patient comfort in and around the insertion site.

Abstract: A method for insertion, maintenance, and removal of urethral catheters in mammals including humans includes steps for preventing or reducing the incidence of catheter associated urinary tract infections. In addition to sterile procedures currently practiced or as may be practiced in the future in connection with catheter use, the method includes the steps of applying an antiseptic, zwitterionic, and acidic skincare solution capable of preserving the stratum corneum to the perineum, meatus, and contiguous mucosa surrounding the insertion site before insertion, after insertion, periodically during the period of indwelling, in connection with any incidence of incontinence, and, optionally, before and after removal of the catheter. Application of the solution optionally is continued after catheter removal on a periodic basis until the threat of an infection associated with catheter use has passed, typically at least about five (5) to seven (7) days and up to thirty (30) days. The solution pH is desirably from about 4.4 to 5.5.

Abstract: An occlusion clearing device for a patient has a housing with a motor(s) that generates repetitive motion, which is reciprocating, rotational or both. A clearing stem including a sheath that has a lumen, wherein aspiration is conducted through the sheath lumen. A wire is located in the sheath lumen and receives repetitive motion from the controller. The sheath terminates in a sheath end having at least one sheath opening. The wire terminates in a wire tip, which may be flat, helical, or tubular. The wire tip is positioned within the sheath end, in proximity to the sheath opening(s), and movement of the wire tip and/or sheath end relative to each other creates shearing forces that break up an adjacent occlusion.
