Abstract
A catheter includes a longitudinally extending catheter body having proximal and distal ends. The catheter body defines a lumen extending longitudinally from a first port defined at the proximal end, through the body, to a second port defined at the distal end. The catheter includes a valve for controlling fluid flow through the second port.

15. A catheter comprising:
-
a longitudinally extending catheter body having proximal and distal ends, the catheter body defining a first lumen extending longitudinally between a first port, defined at the proximal end, and a second port, defined at the distal end, and a second lumen extending from a side of the catheter body to the distal end of the catheter body, the second port providing fluid communication between the first and second lumens; and an elastomeric tube disposed in the second lumen in a first state in sealing engagement with a wall of the second lumen to inhibit fluid flow through the second port; wherein the tube elastically deflects to a second state spaced from the wall of the second lumen for permitting fluid flow through the second port when pressure in the first lumen exceeds a threshold pressure.

19. A catheter comprising:
-
a longitudinally extending catheter body having proximal and distal ends, the catheter body defining a lumen extending longitudinally from a first port, defined at the proximal end, through the body to a second port, defined at the distal end, and a valve seat; and a valve in fluid communication with the second port controls fluid flow through the second port, the valve having; a valve element disposed within the lumen for transition between a first state in sealing engagement with the valve seat to inhibit fluid flow through the second port, and a second state spaced from the valve seat for permitting fluid flow through the second port; and a valve element operator that, when engaged by a deliverable instrument received by the lumen, causes a transition of the valve element from the first position to the second position. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A catheter comprising:
-
a longitudinally extending catheter body having proximal and distal ends, the catheter body defining a lumen extending longitudinally from a first port, defined at the proximal end, through the body to a second port, defined at the distal end; and a valve for controlling fluid flow through the second port, the valve having; an elastic tube surrounding the catheter body in a first state for sealing an outer surface of the catheter body to inhibit fluid flow through the second port; and at least one projection extending radially inwardly from an inner surface of the tube, the projection extending into the lumen through an aperture defined by the catheter body, the projection being configured to be displaced in a radially outward direction by a deliverable instrument received by the lumen, thereby pushing a portion of the tube away from the outer surface of the catheter body to a second position to permit fluid flow through the second port. - View Dependent Claims (36, 37)
