An occlusion system is disclosed for use with a catheter having a catheter proximal end and a catheter distal end. The catheter further 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 for the occlusion member to be received at least partially around an exterior of the catheter lumen with the catheter received within the occlusion member lumen and advanced from the catheter proximal end toward the catheter distal end.
