Biliary decompression and anastomosis stent |
摘要 |
A stent and a method for implanting a stent for decompression and anastomosis formation are provided. The stent includes a non-expandable, generally tubular body having a proximal portion and a distal portion, a lumen extending through at least a portion of the body, a distal opening in the distal portion in fluid communication with the lumen and a proximal opening in the proximal portion in fluid communication with the lumen. The stent further includes a first magnetic element positioned on the distal portion of the tubular body and a second magnetic element movably positionable on the proximal portion of the tubular body. The second magnetic element is configured to surround and move over the proximal portion of the tubular body towards the first magnetic element. |

1. A method for forming an anastomosis between two body cavities, the method comprising:
providing an opening through a wall of a first bodily cavity and a second bodily cavity; inserting a stent through the opening; the stent comprising:
a non-expandable, generally tubular body having a proximal portion and a distal portion, a lumen extending through at least a portion of the body; a distal opening in the distal portion in fluid communication with the lumen, and a proximal opening in the proximal portion in fluid communication with the lumen; anda first magnetic element positioned on the distal portion of the tubular body, the first magnetic element having an opening formed therethrough so that the first magnetic element surrounds a portion of the tubular body; positioning the first magnetic element and the distal portion within the second bodily cavity and positioning the proximal portion within the first bodily cavity so that the lumen is in fluid communication between the first bodily cavity and the second bodily cavity; and placing the second magnetic element over the proximal portion so that the second magnetic element is movable towards the first magnetic element. |
