1. A catheter, comprising:
- a first lumen part and a second lumen part extending along a longitudinal axis in side-by-side relation, said first and second lumen parts forming a proximal portion and a distal portion of the catheter, wherein at least a distal segment of said proximal portion extends along said longitudinal axis and said first and second lumen parts separate from one another at a bifurcation between said distal and proximal portions, wherein said first lumen part extends distally from said bifurcation and includes a first bend so that said first lumen part is concavely curved toward said longitudinal axis on a first side of said longitudinal axis and said second lumen part extends distally from said bifurcation and includes a second bend so that said second lumen part is concavely curved toward said longitudinal axis on a second side of said longitudinal axis.

15. A catheter, comprising:
an elongate body extending between a distal end and a proximal end, said body including a wall defining at least one lumen for fluid flow therethrough, wherein said body includes at least one port at said distal end of said elongate body in communication with said at least one lumen, and further comprising an end cap at said distal end and an actuating mechanism at said proximal end, said end cap being coupled to said actuating mechanism which is operable to remotely move said end cap away from said port to an open position and permit fluid flow through said port and to remotely move said end cap toward said distal end to a closed position to prevent fluid flow through said port, wherein said end cap includes a passage extending therethrough and further comprising a guidewire positionable through said passage and along said elongate body outside said lumen. - View Dependent Claims (16, 17, 18)

19. A catheter, comprising:
a first lumen part and a second lumen part extending along a longitudinal axis in side-by-side relation, said first and second lumen parts forming a proximal portion and a distal portion of the catheter, wherein at least a distal segment of said proximal portion extends along said longitudinal axis and said first and second lumen parts separate from one another at a bifurcation between said distal and proximal portions, wherein said first lumen part extends distally from said bifurcation along a first bend so that said first lumen part is concavely curved relative to said longitudinal axis on a first side of said longitudinal axis and said second lumen part extends linearly and distally from said bifurcation along a second side of said longitudinal axis to a second bend that is curved to locate a distal tip of said second lumen part on said first side of said longitudinal axis. - View Dependent Claims (20)
