Abstract
A multilumen catheter with an inflow or an outflow lumen having at least two tube extensions extending from the distal end of the catheter that open into the inflow or outflow lumen. A device to selectively test each of the two tube extensions for occlusion.
Claims16
A multilumen catheter, comprising:
- an elongated flexible tubular member having a proximal end portion and a distal end portion, the elongated flexible tubular member also having at least one septum forming at least one aspiration lumen and at least one infusion lumen extending between the proximal and distal end portions;
- a first distal end tube and a second distal end tube attached to the distal end portion of the elongated flexible tubular member, the first and second distal end tubes having open proximal and distal ends and in fluid communication with said aspiration lumen;
- a third distal end tube attached to the distal end portion of the elongated flexible tubular member, the third distal end tube having open proximal and distal ends and in fluid communication with said infusion lumen;
- and wherein the distal ends of said first, second, and third distal end tubes are not attached to each other and the distal ends are thereby capable of independent movement.

A multilumen catheter, comprising:
- an elongated flexible tubular member having a proximal end portion and a distal end portion, the elongated flexible tubular member also having a septum forming one aspiration lumen and one infusion lumen extending between the proximal and distal portions;
- a first distal end tube and a second distal end tube attached to the distal end portion of the elongated tubular flexible member, the first and second distal end tubes having open proximal and distal ends and in fluid communication with said aspiration lumen;
- a third distal end tube attached to the distal end portion of the elongated tubular flexible member, the third distal end tube having open proximal and distal ends and in fluid communication with said infusion lumen;
- and
- the first distal end tube having a first longitudinal length between its proximal and distal ends, the second distal end tube having a second longitudinal length between its proximal and distal ends, and the third distal end tube having a third longitudinal length between its proximal and distal ends, and said first and said second longitudinal lengths being less than said third longitudinal length.

A method to test for an occlusion in the aspiration lumen of a catheter, comprising the steps of:
- providing a catheter with an aspiration lumen, a first distal end tube, and a second distal end tube, said distal end tubes having open proximal and distal ends and a passageway therebetween, said distal end tubes extending from the distal end of the catheter and fluidly connecting the passageways therein to the aspiration lumen;
- providing a testing catheter with a first outflow lumen and a second outflow lumen, and at least one extension tube with open proximal and distal ends and a passageway therebetween, said extension tube extending from the distal end of the testing catheter and fluidly connecting the passageway to the first outflow lumen;
- feeding the distal end of the testing catheter into the proximal end of the aspiration lumen until the passageway in the first distal end tube receives the extension tube on the testing catheter;
- pulling a vacuum on the first lumen in the testing catheter.
