| 摘要 |
An occlusion system is disclosed for use with a catheter having a catheter proximal end and a catheter distal end. The catheter has a catheter wall with an outer catheter dimension at the catheter distal end and with the catheter wall defining a catheter lumen with a longitudinal axis extending from the catheter proximal end and through the catheter distal end. The occlusion system includes an occlusion member having an inner wall and an outer wall. The inner wall defines an occlusion member lumen extending throughout an axial length of the occlusion member. The outer wall is expandable between a contracted state with a first transverse dimension and an expanded state with a second transverse dimension. The second transverse dimension is greater than the outer catheter dimension. The occlusion member is sized to be received within the catheter lumen and advanced from the catheter proximal end to the catheter distal end when the outer wall is in the contracted state and with the occlusion member lumen aligned with the catheter lumen. Further embodiments include a rapid-delivery occlusion member advanced along the outer wall of a pre-placed catheter.
