Atraumatic catheter tip

1. A delivery system comprising:

an elongated catheter shaft having a proximal end and a distal end, the distal end insertable into a body lumen;

a delivery means for delivering an occluding device to a desired location within the body lumen; and

a flexible atraumatic tip on the distal end of the elongated catheter shaft for guiding the elongated catheter shaft through the body lumen, the atraumatic tip having a proximal end coupled onto an outer surface of the distal end of the elongated catheter such that the distal end of the elongated catheter is inside the atraumatic tip, a distal end having a distal leading edge, a slanted facial opening near the distal end of the atraumatic tip, and a flexible elongated portion extending from a distal end of the slanted facial opening to the distal leading edge, wherein the flexible elongated portion is formed with a bend that extends away from a longitudinal length of the flexible atraumatic tip in a direction substantially consonant with the slanted facial opening from about the distal end of the slanted facial opening to the distal leading edge such that, with regard to relative positions to each other, the distal leading edge is located below the distal end of the slanted facial opening and the occluding device is deployed above the distal leading edge.

2. The delivery system of claim 1 , wherein the occluding device includes a self-expanding tubular member deployable from a collapsed position within a lumen of the elongated catheter shaft to an expanded position outside of the elongated catheter shaft.

3. The delivery system of claim 2 , wherein the delivery means comprises a pusher rod slidably received within the lumen of the elongated catheter shaft.

4. The delivery system of claim 1 , wherein the elongated catheter shaft is insertable into a working port of an endoscope.

5. The delivery system of claim 1 , wherein the elongated catheter shaft is insertable into a working port of a hysteroscope.

6. The delivery system of claim 1 , wherein the atraumatic tip comprises a tubular member.

7. The delivery system of claim 6 , wherein the slanted facial opening has a generally ovoid configuration.

8. The delivery system of claim 6 , wherein the distal leading edge is blunt.

9. The delivery system of claim 8 , wherein the blunt distal leading edge has a generally rounded outer face.

10. The delivery system of claim 1 , wherein the atraumatic tip is bendable about midway up a longitudinal length of the slanted facial opening.

11. A delivery system comprising:

an elongated catheter shaft having a proximal end and a distal end, the distal end insertable into a body lumen;

a delivery means for delivering an occluding device to a desired location within the body lumen; and

an atraumatic tip on the distal end of the elongated catheter shaft for guiding the elongated catheter shaft through the body lumen, the atraumatic tip having a proximal end coupled onto an outer surface of the distal end of the elongated catheter such that the distal end of the elongated catheter is inside the atraumatic tip, a distal end, a slanted facial opening near the distal end of the atraumatic tip, and a flexible elongated portion extending from a distal end of the slanted facial opening to the distal end of the atraumatic tip, wherein the flexible elongated portion is formed with a bend that extends away from a longitudinal length of the flexible atraumatic tip in a direction substantially consonant with the slanted facial opening from about the distal end of the slanted facial opening to the distal end of the atraumatic tip such that, with regard to relative positions to each other, the distal end of the atraumatic tip is located below the distal end of the slanted facial opening and the occluding device is deployed above the distal end of the atraumatic tip.

12. The delivery system of claim 11 , wherein the atraumatic tip is bendable about midway up a longitudinal length of the slanted facial opening.

13. A delivery system comprising:

an elongated catheter shaft having a proximal end and a distal end, the distal end insertable into a body lumen; and

a flexible atraumatic tip on the distal end of the elongated catheter shaft for guiding the elongated catheter shaft through the body lumen, the atraumatic tip having a proximal end coupled onto an outer surface of the distal end of the elongated catheter such that the distal end of the elongated catheter is inside the atraumatic tip, a distal end having a distal leading edge, a slanted facial opening near the distal end of the atraumatic tip, and a flexible elongated portion extending from a distal end of the slanted facial opening to the distal leading edge, wherein the flexible elongated portion is formed with a bend that extends away from a longitudinal length of the flexible atraumatic tip in a direction substantially consonant with the slanted facial opening from about the distal end of the slanted facial opening to the distal leading edge such that, with regard to relative positions to each other, the distal leading edge is located below the distal end of the slanted facial opening.

14. The delivery system of claim 13 , wherein the atraumatic tip comprises a tubular member.

15. The delivery system of claim 14 , wherein the slanted facial opening has a generally ovoid configuration.

16. The delivery system of claim 14 , wherein the distal leading edge is blunt.

17. The delivery system of claim 16 , wherein the blunt distal leading edge has a generally rounded outer face.
