摘要:
In some embodiments, a catheterization device includes a tip and includes a body member having a proximal end and a distal end. The body member can define a lumen that extends from the proximal end to the distal end. The catheterization device further includes an expandable portion extending between the tip and the proximal end of the body member. The expandable portion can include a plurality of arms bent to form a resting shape. The expandable member may be configured to expand to allow the body member to extend in response to tension applied to the body member and to retract to the resting shape when tension is withdrawn.
