Apparatus and method for accessing a body site |
摘要 |
A device to access a desired tissue site within a patient's body and separate a tissue specimen from the tissue site. The device includes a probe member having a tissue penetrating distal tip having a plurality of concaved surfaces which form curved cutting edges at the intersection of adjacent concave surfaces. The probe member has an inner lumen which when subjected to a vacuum, secures tissue for the specimen to the surface of a distal tubular section of the probe which may be off-set from a central longitudinal axis. A circular tissue-cutting blade is configured to move longitudinally to sever a tissue specimen from tissue secured to the surface of the distal tubular section by the application of a vacuum to the inner lumen of the probe.
