Abstract
A tissue sampling apparatus and method obtain a sample of tissue from a selected site and place a hemostatic plug at the selected site. The apparatus includes an external needle and an internal needle within the external needle. A chamber in the internal needle is divided by a divider member into a plug compartment for receiving a hemostatic plug, and a sample compartment for receiving a tissue sample. The divider member is resiliently biased into the plug compartment and the internal needle is movable relative to the external needle for admitting the hemostatic plug into the plug compartment and displacing the divider member into the sample compartment, and then closing the chamber. The apparatus then is advanced to the selected site where relative movement between the internal and external needles opens the chamber, allowing the divider member to expel the hemostatic plug from the plug compartment, and admitting a tissue sample into the sample compartment. Subsequent relative movement between the internal and external needles cuts the tissue sample from the surrounding tissue for removal from the selected site upon removal of the apparatus, while the expelled hemostatic plug remains at the site.
