    Abstract: A lock for an outpatient's peripherally inserted central catheter (PICC) line limits access to the catheter by patients seeking to abuse injectable narcotics. The lock has two plastic housing halves which slide together, and which define an interior enclosure which receives the catheter line injection port. The housing halves have overlying flanges, through which a fastener extends to secure the device in a closed configuration. The fastener interacts with the flanges in such a way that it cannot be removed without distorting the device and giving evidence of tampering. A zippered sleeve may be provided which surrounds the line leading to the injection port and which has a pull tab which may be engaged within the housing to further prevent access to the line directly.

  • Publication number: 20140243789
    Abstract: A subcutaneous, venous catheter is provided in conjunction with a method of installation in hemodialysis treatments. The catheter has an implantable hub attached to a first end of the primary lumen. An anchoring back plate is pivottably secured to the catheter hub and surgically anchored to underlying musculature. Once the device is implanted, the hub can be arcuately translated underneath the skin by applying gentle pressure to either side of the hub. To reduce fluid stagnation within and around the lumen, a series of piezo-electric elements are integrated therein. A vibration processor is electrically connected to the piezo-electric elements such that the initiation of electrical current by the vibration processor results in contraction of the piezo-electric elements. Expansion and contraction of these elements propagates low-energy acoustic waves through the lumen, agitating liquid contained therein and improving flow of same through the catheter lumen.

    Abstract: A system for moving particles suspended in a first fluid, and for infusing them into the stream of a second fluid, includes a catheter with a multi-lumen distal separator. The separator is formed with a plurality of parallel lumens, wherein each lumen has a predetermined diameter. Importantly, the diameter of each lumen is dimensioned to sequentially receive particles therethrough, to prevent the particles from flocculating before they enter the stream of the second fluid. A recollection chamber in fluid communication with the separator allows for reconsolidation of the fluid after leaving the separator and for minimizing the damage caused to the vessel when the fluid exits the catheter. An inflatable balloon, affixed to the outside of the catheter, can be provided to regulate flow of the second fluid and thereby facilitate entry of the particles into the stream of the second fluid and increase retention of particles in targeted tissue.

  • Publication number: 20140194853
    Abstract: A hub assembly is provided for accommodating a medical professional to grip and manipulate two components of a catheter hub and move one component longitudinally relative to the other, then removably engaging the two components of the catheter hub to restrict movement there between. The two catheter hub components include a proximal hub and a distal hub. The proximal hub and the distal hub are configured to removably engage with one another. The proximal hub is affixed to a first catheter member, such as a multi-lumen catheter, while the distal hub is affixed to a second catheter member, such as a sheath. The first catheter member and the second catheter member are cooperatively engaged and concentric with one another. Relative movement of the proximal and distal hubs translates into relative movement of the first and second catheter members.

  • Publication number: 20140188079
    Abstract: A device for controlling visibility and access to central venous access devices is comprised of a two-sided body fitted around the torso of a patient. The device has an interior surface and an exterior surface. The interior surface is fitted with a layer of absorbent, wicking material and further includes strips of anti-slip material to fix the device in place. A flexible window is positioned between two lumen retaining flaps and fixed between the interior and exterior surfaces. A pair of indentions is positioned above and below the window. A pair of locking closures is attached to the body over the indentions. The body includes a flexible closure including a resilient gauze section to provide flexibility and size adjustability. The window allows visual access to the intravenous site and prevents patient tampering. The intravenous lines are protected from breakage and tampering by the locking closures, indentions, and lumen retaining flaps.

  • Publication number: 20140180246
    Abstract: An infusion catheter assembly has the ability to infinitely titrate the length of a porous fluid distribution section in situ. The infusion catheter assembly thereby provides a length of infusion that can be infinitely varied over a prescribed range, to control the effective infusion length and the rate of infusion. Using the infusion catheter assembly, a physician has the capability to treat only the length of the vessel desired, thereby preventing excessive drug/patient exposures. The porous fluid distribution section can include an array of spaced apart apertures that vary in size and/or density along the length of the porous fluid distribution section, such that the flow rate remains essentially constant for a given inlet pressure independent of the effective infusion length.

    Abstract: A liquid embolic material may include a mixture of a first solution comprising between about 1.2% and about 2.5% weight per volume (w/v) carboxymethyl chitosan (CCN) in a first solvent and a second solution comprising between about 1.2% and about 2.5% w/v oxidized carboxymethyl cellulose (OCMC) in a second solvent. The liquid embolic material may be used to embolize a targeted embolization location by mixing the first solution and the second solution to form a liquid embolic material (or hydrogel precursor material), introducing the hydrogel precursor material to a targeted embolization location within a body of a patient, and allowing the CCN and the OCMC to react to form the hydrogel material and embolize the targeted embolization location.

    Abstract: A turbulator for promoting mixing of fluids passing through a body lumen includes an elongate flow perturbing component and an elongate shape controlling component freely slidable within the flow perturbing component. The turbulator is adjustable from a low profile, lumen access configuration to a deployed configuration via sliding the shape controlling component within the flow perturbing component. Adjusting the turbulator within a body lumen of a patient induces turbulence within a flow of fluid passing through the body lumen to increase mixing of a treatment fluid with the body fluid by way of the induced turbulence.
