| 摘要 |
A multi-section tubular device suitable for use as a stent is provided. The multisection tubular device includes a first tubular section (12) having a first end and a second end. A second tubular section (18) is connected to the first end of the first tubular section and a third tubular section (20) is connected to the second end of the first tubular section. The first tubular section is more flexible than the second and third tubular sections. One advantage is that the coiled first tubular section is highly flexible axially, radially, and torsionally, which makes the multi-section tubular device resistant to kinking or fracturing. |
