Benefits of technology
This system enhances the capabilities of endoscopic procedures by allowing for complex tissue manipulation, reducing invasiveness, and improving surgical outcomes by enabling multiple instrument movements without compromising visualization, thus reducing recovery time and risk.
Problems solved by technology
Such endoscopes have a number of constraints which limit their usefulness in performing diagnostic and surgical procedures.
And, most of these endoscopes only allow axial and rotational movement of the tool beyond the distal end.
However, this limits the variety and complexity of procedures that may be performed.
For example, procedures which involve tissue approximation pose great difficulty since only one portion of tissue may be grasped at a time and lateral, rather than axial, movement may be required.
However, these additional benefits are achieved at the cost of increased invasiveness.
In addition, access may be difficult or contraindicated in some patients, particularly in the morbidly obese.

Embodiment Construction
I. Overview
[0058] An embodiment of a system 2 of the present invention is illustrated in FIG. 1. The system 2 includes an elongated main body 10 having a proximal end 12 and a distal end 14 terminating in a distal tip 16. The main body 10 is used to access an internal target location within a patient's body. Typically, the distal end 14 is passed through a body orifice and one or more naturally occurring body lumens to the target location, such as in endoscopy, while the proximal end 12 remains outside of the body. Therefore, the main body 10 has a deflectable and / or steerable shaft 20, either due to choice of material or design of the shaft 20 to include links, hinges, coils or other similar structures to allow deflection. Thus, FIG. 1 illustrates the main body 10 in a deflected position wherein the body 10 includes curvatures. Such deflection and / or steering may be useful in traversing body lumens to the target location and is achievable by manipulation of a handle 22 near the pro...

Systems, devices and methods are provided for endoscopic procedures involving tissue manipulations beyond the capabilities of traditional endoscopic instruments. Embodiments of the systems include an elongated main body having a scope therethrough and at least one steerable tool arm which extends from the distal end of the main body. In preferred embodiments, the system includes two tool arms, each arm steerable to form a curve laterally outward which then bends laterally inward so that the arms form an angular shape. In addition, end effectors extend from the distal ends of each tool arm for use in manipulation of tissue. The angular shape brings the end effectors together in view of the scope for cooperative movements which are continuously visible by the surgeon. In addition, the tool arms may be steerable in any additional direction and may be rotateable to allow grasping, elevation and more complex manipulation of tissue.
Description
CROSS-REFERENCES TO RELATED APPLICATIONS [0001] The present application is a continuation of U.S. patent application Ser. No. 10 / 346,709 (Attorney Docket No. 021496-000100US), filed Jan. 15, 2003, the full disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The present invention relates generally to medical devices, systems and methods. More particularly, the present invention relates to devices, systems and methods for use in endoscopic or laparoscopic procedures. [0003] Endoscopy is a form of minimally invasive procedure wherein the interior of the body is accessed and visualized through an orifice in the body, such as the esophagus or rectum. Such access allows a surgeon or physician to view and / or treat internal portions of the orifice or internal tissues or organs which are accessible through the orifice. These procedures may be for diagnostic purposes, such as visual inspection or the removal of a tissue sample for biopsy, or the procedur...
