Patent ID: 7189206

Claim:
An tissue biopsy device for accessing and collecting a tissue specimen from a target site within a patient, comprising: a. a housing having at least one drive unit; b. an elongated probe member which has a longitudinal axis, which has a proximal end configured to be releasably secured to the drive housing in a plurality of discrete orientations about the longitudinal axis prior to insertion into the patient's body, which has an inner lumen extending therein, which has a tissue penetrating distal tip and which has an open section proximal to the tissue penetrating distal tip configured to receive tissue from the target site; and c. an elongated tissue cutter which is slidably disposed within the elongated probe member, which has a tissue cutting surface, which defines at least in part an inner lumen extending therein for receiving a tissue specimen, which is operably connected to at least one drive unit to move the tissue cutter to cut a tissue specimen from tissue extending into the open tissue receiving section of the elongated member; and d. a rotatable tissue accessing cannula which is slidablv disposed concentrically about the tissue cutter, has a proximal end, has a distal end seated against a proximal surface of the tissue penetrating distal tip, has an inner lumen extending therein, has a tissue receiving side port spaced proximal to the distal end thereof in fluid communication with the inner lumen and disposed in the open section of the outer cannula and is operably secured to a drive unit in the housing to rotate the tissue accessing cannula to adjust the operating location of the tissue receiving side port.
