Claims
- 1. A catheter for accepting probes and for introducing fluid through the catheter and into a body cavity, the catheter comprising:
- a catheter body having a continuous outer edge surface with a corresponding maximum outer dimension and having a proximal end and a distal end and having walls defining, in transverse cross-section, lumens including a first wall defining a first lumen having a first cross-sectional dimension approximately half the maximum outer dimension of the catheter body, and a second wall defining a curved lumen wherein the lumen occupies at least a quarter of an arc around the catheter body; and
- a first lumen exit port opening the first lumen to the outside of the catheter proximal of the distal end of the catheter body.
- 2. The catheter of claim 1 wherein the catheter has outer wall surface portion with an outer curvature and the first lumen has a circular transverse cross-sectional configuration and the curved lumen has an outer wall surface adjacent the catheter outer wall surface portion and having a curvature approximating the curvature of the catheter outer wall surface portion.
- 3. The catheter of claim 2 wherein the catheter is circular in transverse cross-section and defines a central axis for the catheter and wherein the first lumen encloses the central axis.
- 4. The catheter of claim 1 wherein the first lumen and the curved lumen are positioned with respect to each other so as to be each bisected by a plane extending longitudinally of the catheter.
- 5. The catheter of claim 1 wherein a substantial portion of the first wall and the second wall has a thickness greater than the shortest distance between the first wall and the outer edge of the catheter body.
- 6. The catheter of claim 1 wherein the maximum outer dimension is approximately 0.101 inches.
- 7. The catheter of claim 1 wherein the cross-sectional area of the first lumen is approximately 0.002 square inches.
- 8. The catheter of claim 1 wherein the cross-sectional area of the second lumen is approximately 0.0016 square inches.
- 9. The catheter of claim 1 further comprising a round lumen plug sealed in the first lumen to direct fluid from the first lumen externally of the catheter.
- 10. The catheter of claim 1 further comprising an injectate port opening the second lumen to the outside of the catheter and an injectate plug in the second lumen distal of the injectate port.
- 11. The catheter of claim 10 further comprising an insert in the second lumen extending distally of the injectate plug to displace air from the second lumen.
- 12. The catheter of claim 11 further comprising a filler between the insert and the wall of the second lumen.
- 13. A catheter for accepting probes and for introducing fluid through the catheter and into a body cavity, the catheter comprising:
- a catheter body circular in transverse cross-section and defining a central axis and having a continuous outer edge surface with a corresponding maximum outer dimension and having a proximal end and a distal end, said catheter body having walls defining lumens in transverse cross-section and ports including:
- a first wall defining a first lumen having a first cross-sectional dimension approximately half the maximum outer dimension of the catheter body wherein a substantial portion of the first wall has a thickness greater than shortest distance between the first wall and the outer edge of the catheter body and wherein the first lumen encloses the central axis;
- a second wall defining a second, curved lumen wherein the second lumen occupies at least a quarter of an arc around the catheter body;
- a first lumen exit port opening the first lumen to the outside of the catheter proximal of the distal end of the catheter body; and
- a second lumen exit port opening the second lumen to the outside of the catheter.
- 14. An elongated flexible transport catheter having a catheter body, and further having at least two independent lumens extending longitudinally from a catheter proximal end to a catheter distal end, wherein the lumens include:
- a first lumen having a circular cross-sectional area of approximately thirty percent of the total cross-sectional area of the catheter body;
- a second lumen having a curved cross-sectional area of approximately twenty percent of the total cross-section area of the catheter body;
- a first lumen exit port opening the first lumen to the outside of the catheter proximal of the distal end of the catheter body; and
- a second lumen exit port opening the second lumen to the outside of the catheter.
