Claims13
A device for marking a target location in a patient's body, comprising:
- a body portion configured to mark the target location, the body portion defining a longitudinal length and including a proximal end and a closed distal end;
- and
- an anchoring portion configured to be inserted in tissue in a proximal to distal direction and having a proximal portion connected to the proximal end of the body portion and a sharpened distal portion disposed in spaced relation to the body portion to define a longitudinal space between the anchoring portion and the body portion such that movement of the body portion in the proximal to distal direction is adapted to draw the tissue into the longitudinal space to prevent migration of the body portion within the tissue, the anchoring portion defining a longitudinal length that extends at least partially along the longitudinal length of the body portion, wherein the sharpened distal portion of the anchoring portion extends distally beyond the closed distal end of the body portion.
