Apparatus and method for performing a tissue resection procedure
First Claim
1. A tissue resectioning system, comprising:
- a resection head mounted at a distal end of an elongate flexible body, the resection head including a marker thereon wherein, when in an operative position, the resection head is located within a body lumen with the elongate flexible body extending through the body lumen to a naturally occurring body orifice;
an imager which remains outside the patient'"'"'s body, the imager generating image data of a selected region within the patient'"'"'s body including a predetermined portion of tissue marked for resection;
an image processing unit analyzing the image data to define a region of tissue to be resectioned and to locate the marker; and
a control unit controlling the resection head based on the defined region of tissue and the location of the marker to resect the region of tissue.

Abstract
An apparatus and a method for performing a medical procedure is disclosed. In an embodiment for an apparatus of the present invention, the apparatus includes a positioning system and a resection device disposed within the positioning system. The positioning system includes an imaging device, a video processor coupled to the imaging device, a computer coupled to the video processor, and a video display coupled to the computer. In an embodiment for a method of practicing the present invention, the method includes the steps of creating an image of a lesion within a patient'"'"'s body on an imaging device. Data representative of the lesion image is processed by a video processor. Tissue margins around the lesion are defined by a processor based on the processed data representative of the lesion image and a resection device is operated during a resection procedure within the patient'"'"'s body based upon the defined tissue margins.
