Claim Text:
1. A tissue penetrating element that facilitates advancement through soft tissue to a desired intracorporeal location, comprising: a. a proximal base; b. a centrally located sharp distal point distal to the proximal base and located on a central longitudinal axis; c. a first concave surface that extends from the sharp distal point to the proximal base; d. a second concave surface that extends from the sharp distal point to the proximal base and which intersects the first concave surface forming therewith a first continuous curved tissue cutting edge that lies in a first plane parallel to and passing through the central longitudinal axis and extends proximally from the sharp distal point to the proximal base; and e. a third concave surface that extends from the sharp distal point to the proximal base and which intersects the first concave surface forming therewith a second continuous curved tissue cutting edge that lies in a second plane parallel to and passing through the central longitudinal axis and extends proximally from the sharp distal point to the proximal base and which intersects the second concave surface forming therewith a third continuous curved tissue cutting edge that lies in a third plane parallel to and passing through the central longitudinal axis and extends proximally from the sharp distal point to the proximal base.
