Abstract
An apparatus for providing access to a target site in a living body, comprises a first elongated member including a proximal opening to a first lumen and a branching point at a distal end thereof and a second lumen open to the first lumen at the branching point, the second lumen extending to a second lumen distal opening at a first connector, the first connector configured to engage a proximal end of a first lumen of a multi-lumen catheter in combination with a third lumen open to the first lumen at the branching point, the third lumen extending to a third lumen distal opening at a second connector, the second connector configured to engage a proximal end of a second lumen of a multi-lumen catheter.
Claims23
An apparatus for providing access to a target site in a living body, comprising:
- a first elongated member including a proximal opening to a first lumen and a branching point at a distal end thereof;
- a second lumen open to the first lumen at the branching point, the second lumen extending to a second lumen distal opening at a first connector, the first connector configured to engage a proximal end of a first lumen of a multi-lumen catheter;
- a third lumen open to the first lumen at the branching point, the third lumen extending to a third lumen distal opening at a second connector, the second connector configured to engage a proximal end of a second lumen of a multi-lumen catheter.
The apparatus of claim 8, further comprising a second flow control valve in the third lumen, the second flow control valve permitting fluid flow through the third lumen only when a pressure in the third lumen is at least a second threshold level.
An apparatus, comprising:
- a first and second set of lumens for fluid flow, each set comprising at least one of said lumens;
- and
- at least one valve sensitive to a predetermined fluid flow parameter;
- wherein the valve channels fluid flow into the second set of lumens during flow conditions above the predetermined fluid flow parameter.
