    摘要： A catheter system includes a structure defining a proximal orifice, a distal orifice, and a fluid passage extending therebetween. The catheter system further includes an actuator movable in relation to the structure between a first location and a second location. In addition, the catheter system includes a member movable in relation to the structure between (i) a first position in which the member extends through the distal orifice so that a proximal part of the member is positioned within the fluid passage and a distal part of the member is positioned outside of the fluid passage, and (ii) a second position in which the member is entirely located within the fluid passage. The catheter system additionally includes a linkage connected between the actuator and the member. Movement of the actuator from the second location to the first location causes movement of the member from the second position to the first position.

    摘要： 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.
