Abstract
A medical securing device that includes (1) a pointed tip and (2) a depth stop is provided. The depth stop includes an apex portion coupled to a trough portion. The depth stop limits the depth of penetration of the pointed tip into a wall of a body lumen. In one or more embodiment, the medical securing device may be constructed from a length of shape memory wire. Thus, during deployment, the medical securing device may spring away from a medical device to which the medical securing device is coupled such that the pointed tip makes contact with and punctures, to a limited depth, a body lumen wall. In various embodiments, a pair of barbs may be coupled to from an integral two pronged barb.
