A device for accessing and collecting tissue from a target site within a patient, comprising: a. an elongated probe which has a longitudinal axis, which has a proximal end configured to be secured to a drive, which has an inner lumen extending therein, which has a distal end and which has an aperture proximal to the distal end configured to receive tissue from the target site; and b. a tissue penetrating tip on the distal end which has i. a proximal base secured to the distal end of the elongated probe, ii. a sharp distal point distal to a proximal base, the device characterized in that said tissue penetrating tip has iii. a first concave surface having a center line extending from the base to the sharp distal point, iv. a second concave surface which has a center line extending from the base to the sharp distal point and which intersects the first concave surface forming therewith a first curved cutting edge that leads to the sharp distal point, and v. a third concave surface which has a center line extending from the base to the sharp distal point and which intersects the first concave surface forming therewith a second curved cutting edge leading to the sharp distal point and which intersects the second concave surface forming therewith a third curved cutting edge that leads to the sharp distal point; and a tissue cutting means which is disposed within the elongated probe member and which is configured to cut a tissue specimen from tissue extending into the tissue receiving aperture of the elongated probe. a. an elongated probe which has a longitudinal axis, which has a proximal end configured to be secured to a drive, which has an inner lumen extending therein, which has a distal end and which has an aperture proximal to the distal end configured to receive tissue from the target site; and b. a tissue penetrating tip on the distal end which has i. a proximal base secured to the distal end of the elongated probe, ii. a sharp distal point distal to a proximal base, the device characterized in that said tissue penetrating tip has iii. a first concave surface having a center line extending from the base to the sharp distal point, iv. a second concave surface which has a center line extending from the base to the sharp distal point and which intersects the first concave surface forming therewith a first curved cutting edge that leads to the sharp distal point, and v. a third concave surface which has a center line extending from the base to the sharp distal point and which intersects the first concave surface forming therewith a second curved cutting edge leading to the sharp distal point and which intersects the second concave surface forming therewith a third curved cutting edge that leads to the sharp distal point; and a tissue cutting means which is disposed within the elongated probe member and which is configured to cut a tissue specimen from tissue extending into the tissue receiving aperture of the elongated probe. i. a proximal base secured to the distal end of the elongated probe, ii. a sharp distal point distal to a proximal base, the device characterized in that said tissue penetrating tip has iii. a first concave surface having a center line extending from the base to the sharp distal point, iv. a second concave surface which has a center line extending from the base to the sharp distal point and which intersects the first concave surface forming therewith a first curved cutting edge that leads to the sharp distal point, and v. a third concave surface which has a center line extending from the base to the sharp distal point and which intersects the first concave surface forming therewith a second curved cutting edge leading to the sharp distal point and which intersects the second concave surface forming therewith a third curved cutting edge that leads to the sharp distal point; and a tissue cutting means which is disposed within the elongated probe member and which is configured to cut a tissue specimen from tissue extending into the tissue receiving aperture of the elongated probe.
