Medical devices and methods thereof for determining bacterial infections in blood. The medical devices and methods thereof can utilize a coating including an antibody conjugated to a reporter protein configured to indicate a bacterial infection in a patient's blood by way of an antigen thereof. Exemplary medical devices include, but are not limited to, a catheter assembly, an AV fistula needle set, an extension set for either a catheter assembly or an AV fistula needle set, and a hemodialysis tubing set. The medical devices and methods thereof can utilize immunochromatographic separation of the antibody and an antigen-antibody complex to indicate a bacterial infection in a patient's blood.

The invention relates to a cannulation robot for the automated affixing of a cannula to a patient. The cannulation robot comprises a fixing apparatus for affixing the cannula to the patient by means of an adhesive carrier. The cannulation robot comprises a positioning device designed to position a cannula holder of the cannula to an area of the patient's skin. The cannulation robot comprises an actuator device for a guide means, wherein the guide means is designed to guide the adhesive carrier to said skin area. The actuator device is designed to activate the guide means and thereby move the adhesive carrier by means of the guide means toward the skin area, wherein the adhesive carrier contacts the skin area as a result of the movement and adheres to same as well as is disposed such that it is connected to the cannula at least after being adhered.

A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.

An external end device has a casing (4), including a base (5), in which a distal opening (12) is formed which receives a funnel-shaped septum (14) having a tube trunk (140). Inside the tube trunk (140) the catheter (3) is connected to the distal section (16) of the fitting (15). A tubular coating (2) has a proximal end adapted to be grafted onto the tube trunk (140) and a distal end coaxially adhering to the catheter (3). A pair of bands (90, 91) of tissue-ingrowth material is fixed on the tubular coating (2), and an anchor ring (92), equipped with anchoring means, is sandwiched between the bands (90, 91).

The present invention is directed to a dual lumen cannula configured to be inserted into a patient's body as simple as a single lumen cannula. The dual lumen cannula includes at least one inner lumen configured to be inserted into an outer lumen and connected via an inner lumen connection unit and an outer unit connection unit. Embodiments of the presenting invention further allow for the connection of at least one flow router to the other end of the inner lumen connection unit. When installed, the outer lumen is first inserted into the patient's body, followed by the insertion of the inner lumen into the outer lumen of the already cannulated patient until the inner lumen connector unit is in coupling contact with the outer lumen connector unit. The invention is also directed to a transformable dual lumen cannula into a single lumen cannula and vice versa that allow patients that are first being treated by low flow approach to be treated by high flow approach.

A skin surface indwelling device for guiding punctures includes: an indwelling tube (13) having an inside tunnel (P) substantially extending along the longitudinal direction of the indwelling tube (13), the tunnel (P) is used for guiding needle (N), the indwelling tube (13) has a proximal end positioned above the skin surface (S) and a distal end positioned under the skin surface (S) in indwelling state; a support (11) having a bottom surface on its bottom that directly or indirectly contacts with the skin surface (S), the support (11) supports and fixates the indwelling tube (13); and a sealing elements (141,142) configured to seal the tunnel (P). The skin surface indwelling device for guiding punctures can shorten the time of establishing a puncture tunnel in the buttonhole puncture method, and help to build the puncture tunnel. In addition, the skin surface indwelling device can also guide the puncture needle (N) when puncturing, and protect the immature puncture tunnel.

A system and method for identifying a disruption of a flow from an extracorporeal circuit to a patient circulatory system is based on flow rate data, such as from a venous line of the extracorporeal circuit. A patient contribution to the flow rate data is identified and monitored to assess a disruption of the extracorporeal circuit and the patient circulatory system, or access device. A spectrum analysis can be performed on the flow rate data to identify a harmonic corresponding to the patient contribution, wherein a change in or disappearance of the identified harmonic can be used to identify a disruption of the flow.

A modular tunneled catheter is provided that allows lumen length and cuff positioning to be adjusted based on the size of a patient. This catheter should be useful for any patient who would benefit from customized fitting of a catheter to their measurements. Methods of using the modular catheter for hemodialysis, peritoneal dialysis, and fluid drainage, including drainage of plural effusions from the lungs or malignant ascites from the abdomen are also described.

An aspiration system includes a plurality of catheters located at least partially within the lumen of an outer sheath. The outer sheath and the catheters are configured to slide relative to each other between a first state in which the distal ends of the catheters are located within the lumen of the outer sheath, and a second state in which the distal end and an end length section of each catheter is extended through the distal end of the outer sheath and outside of the lumen of the outer sheath. The end length section of each catheter is configured to spring or flare outward relative to the first state, when the outer sheath and the plurality of catheters are in the second state. The distal end of the outer sheath may be placed in an inferior vena cava or iliac vein in a transplant kidney patient, adjacent at least one renal vein, with the outer sheath and the plurality of catheters in the first state. Then, the system may be transitioned to the second state to cause the end length sections of the catheters to spring or flare outward adjacent the renal vein. The catheters are connected to a suction source for aspiration through the catheter end length sections.

An electromagnetic radiation (EMR) delivery system for delivering EMR at wavelengths, intensities, exposures, and durations to locations inside and/or outside a patient’s body in, on, and surrounding a tubular structure such as a tube, catheter, and/or a catheter extension to prevent, reduce, and/or eliminate infectious agents in, on, or surrounding the tubular structure. A smart light engine box generates the therapeutic EMR, controls treatments, and monitors the health of the system. A fiber optic disposable makes at-home use of the EMR delivery system possible. Specific embodiments of the EMR delivery system for use with peritoneal dialysis catheters, dialysis accesses, and hemodialysis accesses are also disclosed.
