Abstract

An intravascular device delivery system includes an elongated member with a proximal end, a distal end, and a longitudinal axis therebetween. The elongated member includes a multilumen catheter having a catheter wall with a plurality of lumen in the catheter wall. The plurality of lumen extends from a proximal end of the elongated member to a distal end of the elongated member. A lumen ratio of the cross-sectional area of the plurality of lumen and the cross sectional area of the catheter wall is greater than 30%.

Claims

1. An intravascular device delivery system, the system comprising:

an elongated member with a proximal end, a distal end, and a longitudinal axis therebetween, the elongated member including;

a multilumen catheter having a catheter wall with a plurality of lumen in the catheter wall, the plurality of lumen extending from a proximal end of the elongated member to a distal end of the elongated member, wherein a lumen ratio of a cross-sectional area of the plurality of lumen and a cross sectional area of the catheter wall is greater than 30%.

2. The system of claim 1, wherein the lumen ratio is greater than 40%.

3. The system of claim 2, wherein the lumen ratio is greater than 50%.

4. The system of claim 3, wherein at least one of the plurality of lumen is reinforced.

5. The system of claim 4, further comprising an outer jacket around the catheter wall.

6. The system of claim 5, further comprising an inner liner.

7. The system of claim 6, wherein at least one of the lumen of the plurality of lumen is elliptical.

8. The system of claim 7, wherein at least one of the lumen of the plurality of lumen is round.

9. The system of claim 6, wherein at least one of the lumen of the plurality of lumen is elliptical and at least one other lumen of the plurality of lumen is round.
