Abstract
A catheter system includes a structure defining a fluid passage and a distal orifice, the structure having a first coupling configured to connect to a second coupling of a fluid line of a dialysis machine. The catheter system further includes a first spring supported by the structure and being configurable between an expanded configuration and a compressed configuration. When the first spring is in the expanded configuration, the first spring extends through the distal orifice so that (i) a proximal part of the first spring is positioned within the fluid passage, and (ii) a distal part of the first spring is positioned outside of the fluid passage. When the first spring is in the compressed configuration, the first spring is positioned entirely within the fluid passage of the structure.
