Apparatus and method for endoscopic colectomy
First Claim
1. An endoscopic device for approximating tissue within a hollow body organ, comprising:
- an elongate body defining a longitudinal axis comprising a selectively steerable distal portion and an articulatable proximal portion;
means for automatically controlling the articulatable proximal portion to assume a selected shape defined by said selectively steerable distal portion when the elongate body is advanced distally or proximally;
a first tissue approximation component positioned about the elongate body and adapted to adhere to a first region of tissue; and
a second tissue approximation component positioned about the elongate body proximal to the first tissue approximation component, wherein the second tissue approximation component is adapted to adhere to a second region of tissue,wherein the first tissue approximation component or the second tissue approximation component are moveable relative to the longitudinal axis of the elongate body to approximate the first region of tissue to the second region of tissue.

Abstract
Apparatus and methods for endoscopic colectomy are described herein. A colectomy device having a first and a second tissue approximation device is mounted on a colonoscope separated from one another. During deployment of the colectomy device, a diseased portion of the colon is positioned inbetween the tissue approximation devices. The tissue approximation devices are radially expanded such that they contact and grasp the colon wall at two sites adjacent to the diseased portion of the colon. The diseased portion is separated from the omentum and is transected using a laparoscope or is drawn into the colonoscope for later removal. The tissue approximation devices are then urged towards one another over the colonoscope to approximate the two free edges of the colon into contact together where they are fastened to one another using the tissue approximation device as a surgical stapler to create an end-to-end anastomosis.

17. An endoscopic device for approximating tissue within a hollow body organ, comprising:
-
an elongate body defining a longitudinal axis comprising a selectively steerable distal portion and an automatically controllable proximal portion; an electronic motion controller, wherein said electronic motion controller controls said automatically controllable proximal portion to assume a selected shape defined by said selectively steerable distal portion when said elongate body is advanced distally or proximally; a first tissue approximation component positioned about the elongate body and adapted to adhere to a first region of tissue; and a second tissue approximation component positioned about the elongate body proximal to the first tissue approximation component, wherein the second tissue approximation component is adapted to adhere to a second region of tissue, and wherein the first tissue approximation component or the second tissue approximation component are moveable relative to the longitudinal axis of the elongate body to approximate the first region of tissue to the second region of tissue. - View Dependent Claims (18, 19, 20)
