Devices for transferring fluid to or from a subject include an extension tube assembly with an axially extending inner tube configured to couple to an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen and an axially extending inner tube. The inner tube extending through the tubular cannula defines an exposed needle tip and is in fluid communication with the inner tube of the extension tube assembly. The needle tip extends out of a distal end of the tubular cannula a suitable distance.

The disclosed device, systems and methods relate to a novel catheter, system and methods. Exemplary embodiments comprise a plurality of lumens and balloons for insertion into the aorta and vena cava. These catheters are for use in cardiopulmonary resuscitation and other medical or surgical conditions that require emergency restoration of cerebral and cardiac blood supply.

An assembly of a dual lumen tubing and a dual bore connector has a first flow conduit along a first lumen and a first bore, and has a second flow conduit from a second bore, via a circumferential groove and along a second lumen. The assembly can be used in connection with an extracorporeal circuit of a haemodialysis machine or an infusion set.

A breathing circuit component includes an inlet, an outlet and an enclosing wall. The enclosing wall defines a gases passageway between the inlet and the outlet. At least a region of the enclosing wall is formed from a breathable material that allows the passage of water vapor without allowing the passage of liquid water or respiratory gases. The breathing circuit component may be the expiratory limb of a breathing circuit.

Manifolds and methods of operating manifolds are provided. An example manifold for controlling multi-lumen devices is provided that includes a substance supply mechanism. The substance supply mechanism independently provides a substance to, or remove a substance from, each of a plurality of lumens. The example manifold also includes a lumen selection mechanism. The lumen selection mechanism selectively opens and closes a connection between the substance supply mechanism and at least one of the plurality of lumens. A corresponding method of operation is also provided. An example embodiment also includes a manifold for use with a vessel seclusion device.

A tube coupling component (4;6) serves for use in a tube coupling system and an irrigation system. The tube coupling component (4;6) comprises a male coupling part (12) opposite a respective female coupling part (11), or a first end fitting (33) opposite a respective second end fitting (34), which tube coupling component (4;6) has an interior pipe (13;31) that extends axially inside an exterior pipe (14;32), wherein the interior pipe (13;31) and the exterior pipe (14;32) are concentric.

Apparatus for use in dialyzing a patient, the apparatus comprising: a hemodialysis catheter comprising: an elongated body having a proximal end and a distal end, wherein the distal end terminates in a substantially planar distal end surface; first and second lumens extending from the proximal end of the elongated body to the distal end of the elongated body, wherein the first and second lumens terminate on the substantially planar distal end surface in first and second mouths, respectively, arranged in side-by-side configuration, and further wherein the first and second lumens are separated by a septum; and first and second longitudinal slots formed in the distal end of the elongated body and communicating with the interiors of the first and second lumens, respectively, the first and second longitudinal slots opening on the substantially planar distal end surface; wherein the first and second longitudinal slots each has a length and a width, relative to the dimensions of the first and second lumens and the rate of blood flow to be passed through the hemodialysis catheter, such that (i) when a given lumen is to be used for a return function, the primary blood flow will exit the mouth of that lumen, and (ii) when a given lumen is to be used for a suction function, the primary blood flow will enter the proximal end of the longitudinal slot associated with that lumen, whereby to minimize undesirable recirculation of dialyzed blood.

The present technology relates generally to a method and device for closing percutaneous punctures, and more particularly to a multi-lumen tamper for such a device. A closure device for sealing a percutaneous puncture in a wall of a body passageway is disclosed, the closure device including a plug configured to engage a surface of the puncture; a toggle configured to engage an internal surface of the body passageway; an elongate filament configured to associate the plug with the toggle; a locking member configured to engage the plug; and a tamper comprising at least two lumens, wherein a first lumen of the at least two lumens is configured to deliver a pharmaceutical agent to the plug.

A dual-chamber syringe may include an end wall and a primary plunger. The primary plunger may include a primary stopper. The primary stopper may form a primary chamber with the end wall. A secondary plunger may be in mechanical association with the primary plunger. The secondary plunger may include a secondary stopper. The secondary stopper may form a secondary chamber with the primary stopper. A primary nozzle may extend from the end wall and may be in fluid communication with the primary chamber. A secondary nozzle may extend from the end wall and may be in fluid communication with the secondary chamber.

An assembly comprises a manifold configured to couple to a medical fluid cassette and a multi-lumen tube comprising a plurality of lumens within an outer wall of the multi-lumen tube. The manifold has a plurality of fluid connection ports and can be connected to the multi-lumen tube (e.g., via an adapter).
