ABSTRACT:
A surgical access device and method are provided for endoscopic surgeries comprising biopsies or other surgical cutting procedures. The device generally comprises a substantially rigid first channel associated with a first port and a second channel associated with a second port of a proximal housing. The first or main channel extends to a curved distal end of the device, and the second channel is connected to a guide channel extending tangential to the main channel. The guide channel comprises substantially noncompliant material and has a pre-insertion position such that a cross-section of an inserted portion of the device is substantially the same as a cross-section of the main channel. A preferred method of the present invention includes the use of an open-loop device formed at a distal tip of an introducer and an aspiration tube during the location, excision and removal of one or more tissue specimens.
