Abstract
A catheter system includes a guide catheter having a lumen defining a distal orifice. The catheter system further includes a conduit segment positioned within the lumen and movable between (i) an upper position at which the conduit segment is entirely contained within the lumen of the guide catheter, and (ii) a lower position at which the conduit segment extends through the distal orifice so as to be partially positioned outside of the guide catheter. The catheter system further includes an actuator wire positioned within the lumen of the guide catheter and coupled to the conduit segment. Movement of the actuator wire causes movement of the conduit segment.

2. A method of performing dialysis on a body of a patient with a catheter system having (i) a lumen that defines a distal orifice, and (ii) a member that defines a fluid passage aligned with said lumen, comprising:
-
(a) performing a first dialysis session with said catheter system while said member is at least partially advanced out of said lumen through said distal orifice so that a distal end of said member is located outside of said lumen;
(b) maintaining said distal end of said member within said lumen after step (a); and
(c) performing a second dialysis session after step (b) with said catheter system while said member is at least partially advanced out of said lumen through said distal orifice so that said distal end of said member is located outside of said lumen, wherein said member is located within said body continuously between completion of said step (a) and commencement of said step (c). - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A method of performing a series of medical procedures with a catheter system having (i) a lumen that defines a distal orifice, and (ii) a member positioned within said lumen and defining a fluid passage, comprising:
-
(a) performing a first medical procedure with said catheter system while said member is at least partially advanced out of said lumen through said distal orifice so that a distal end of said member is located outside of said lumen;
(b) maintaining said distal end of said member within said lumen after step (a); and
(c) performing a second medical procedure after step (b) with said catheter system while said member is at least partially advanced out of said lumen through said distal orifice so that said distal end of said member is located outside of said lumen, wherein said member is located within said lumen continuously between completion of said step (a) and commencement of said step (c). - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method of performing a series of medical procedures with a catheter system having (i) a lumen that defines a distal orifice, and (ii) a member positioned within said lumen and defining a fluid passage, comprising:
-
(a) performing a first medical procedure with said catheter system while said member is at least partially advanced out of said lumen through said distal orifice;
(b) maintaining all of said member within said lumen after step (a); and
(c) performing a second medical procedure after step (b) with said catheter system while said member is at least partially advanced out of said lumen through said distal orifice. - View Dependent Claims (35, 36, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
