1. A medical device for forming a fluid pathway, comprising:
a hollow member defining a longitudinally extending lumen configured to receive a penetrating member of a delivery catheter for deployment of the medical device, the hollow member comprising a middle portion and a first retention member at a first end portion of the hollow member adjacent a first end of the middle portion, and the hollow member configured to move from a first configuration to a second configuration such that:
a length of the middle portion decreases;
a diameter of the lumen increases; and
the first retention member radially expands into a first curved surface, the first curved surface configured to atraumatically engage a first tissue, wherein, in the second configuration, terminal ends of the first retention member bend away from the first curved surface and at least a portion of the first retention member extends over the middle portion.
