摘要： The present disclosure provides apparatus and methods for removing thrombus outside of a hemodialysis. The hemodialysis catheter comprises an elongate shaft comprising a plurality of lumens. A first lumen has a first distal port. The first lumen is configured for the flow of a fluid in a first direction. A second lumen has a second distal port proximal to the first distal port. The second lumen is configured for the flow of the fluid in a second direction opposite to the first direction. A third lumen has a third distal port proximal to the second distal port. An elongate device is disposed through the third lumen. The elongate device has an operable member on a distal end or a device to connect to an operable member disposed on the elongate shaft. The operable member is configured to engage and remove thrombus from an exterior surface on the elongate shaft.

摘要： A catheter assembly includes a multi-lumen catheter and fluid supply apparatus for supplying fluid to said multi-lumen catheter. The fluid supply apparatus includes an inlet element for coupling to a supply of catheter fluid, a plurality of fluid outlet elements arranged to be each coupled to a respective lumen of the catheter and a flow splitter arranged between the inlet element and the outlet elements. The flow splitter is able to split or divert flow of fluid from the inlet to at least one of the plurality of outlets. For this purpose, the preferred embodiment includes a gate for directing fluid flow to one or more of the outlet elements. There may also be provided a diffuser and a nozzle.
