Abstract

Medical devices and methods used to cause hemostasis of blood vessels located along the gastrointestinal tract. The medical devices include a clip having a stem, an anchor at a first end of the stem and a bolster at or near a second end of the stem. Methods of deploying the medical devices are disclosed.

Claims

1. A medical device for causing the hemostasis of a blood vessel located along the gastrointestinal tract, said medical device comprising:

a stem having a first end and a second end, wherein said stem has at least one transverse hole therein;

an anchor at the first end of said stem; and

a movably positionable bolster at or near the second end of said stem, wherein said bolster includes;

a central opening, wherein said central opening is wider than said stem; and

a flap adapted to be inserted into said at least one transverse hole in said stem.

2. The medical device of claim 1, wherein said medical device comprises stainless steel.

3. The medical device of claim 1, wherein said medical device comprises nitinol.

4. The medical device of claim 1, wherein said medical device comprises a polymeric material.

5. The medical device of claim 1, wherein said stem is approximately 0.5-2 centimeters in length.

6. The medical device of claim 1, wherein said stem is approximately 0.5-5 millimeters in diameter.

7. A medical device for causing the hemostasis of a blood vessel located along the gastrointestinal tract, said medical device comprising:

a stem having a first end and a second end;

an anchor at the first end of said stem, wherein said anchor comprises at least one anchor member extending away from said stem and towards the second end of said stem, and further wherein a distance between a first end proximal to said stem of said at least one anchor member and a second end distal from said stem of said at least one anchor member is at least twice the diameter of said stem; and

a bolster at or near the second end of said stem, wherein said bolster is rigidly attached to said stem.

8. The medical device of claim 7, wherein said medical device comprises stainless steel.

9. The medical device of claim 7, wherein said medical device comprises nitinol.

10. The medical device of claim 7, wherein said medical device comprises a polymeric material.

11. The medical device of claim 7, wherein said stem is approximately 0.5-2 centimeters in length.

12. The medical device of claim 7, wherein said stem is approximately 0.5-5 millimeters in diameter.

13. A system to achieve the hemostasis of a blood vessel located along the gastrointestinal tract, said system comprising:

a clip, said clip comprising;

a stem having a first end and a second end;

an anchor at the first end of said stem, wherein said anchor comprises at least one anchor member extending away from said stem of said clip and towards the second end of said stem, and further wherein a distance between a first end proximal to said stem of said at least one anchor member and a second end distal from said stem of said at least one anchor member is at least twice the diameter of said stem; and

a bolster at or near the second end of said stem, wherein said bolster is rigidly attached to said stem; and

a delivery device.

14. The system of claim 13, wherein said delivery device comprises:

an endoscope; and

a delivery tube adjacent to said endoscope wherein said clip is removably positionable within said delivery tube.

15. The system of claim 14, further comprising an outer sheath surrounding said endoscope.

16. The system of claim 15, wherein said delivery tube is positioned between said endoscope and said outer sheath.

17. The system of claim 14, further comprising a pusher bar, said pusher bar movably disposed within said delivery tube and releasably engageable with said bolster.
