Abstract:
1. A medical device, comprising: an elongate shaft extending along a longitudinal axis, the shaft including a proximal portion, and a distal portion; and a distal tip disposed at the distal portion of the shaft, the distal tip including a proximal section disposed adjacent to the distal portion of the shaft, and a distal section, the distal section being pre-formed into a flared position wherein at least a part of the distal section extends at an angle away from the longitudinal axis such that the distal section includes a distal end that terminates at a point further from the longitudinal axis than the proximal section of the distal tip; wherein the distal tip is configured to be shifted through the application of a force by a loading tool from the flared position to a second position in which the distal section of the distal tip extends about the longitudinal axis such that the distal ten terminates at a point closer to the longitudinal axis that when in the flared position; wherein the distal tip is pre-formed such that it shifts from the second position back to the flared postion when the force is removed.
