1. An apparatus for facilitating the creation of an anastomosis in bodily tissue, the apparatus comprising:
- a first base positioned opposite from a second base to define an interior space therebetween, the bases and interior space defining a longitudinal axis and a lateral axis, the first and second bases being comprised of a degradable or resorbable material;
a first clamp member having a proximal portion and a distal portion, the first clamp member being separate and distinct from both bases and attached thereto and projecting laterally therefrom, wherein the proximal portion and the distal portion are rotatable relative to the first and second bases;
a second clamp member having a proximal portion and a distal portion, the second clamp member being separate and distinct from both bases and attached thereto and projecting laterally therefrom, wherein the proximal portion and the distal portion are rotatable relative to the first and second bases;
the first and second clamp members each operable between a delivery state and a deployed state, the first and second clamp members being biased towards the deployed state, the deployed state of the first clamp member defining a first interior space in communication with the interior space, and the deployed state of the second clamp member defining a second interior space in communication with the interior space;
the delivery state of the first clamp member having the proximal portion and the distal portion rotated away from each other, the delivery state of the second clamp member having the proximal portion and the distal portion rotated away from each other; and
the deployed state of the first clamp member having the proximal portion and the distal portion of the first clamp member in close proximity to each other to hold the bodily tissue therebetween, the deployed state of the second clamp member having the proximal portion and the distal portion of the second clamp member in close proximity to each other to hold the bodily tissue therebetween.

Abstract
The present embodiments provide medical apparatuses, systems, and methods for rapidly forming an anastomosis between two viscera. The medical apparatus generally comprises two bases with two clamp members rotatably attached to the bases, the clamp members being capable of compressing tissue. The system generally comprises positioning and then deploying the medical apparatus between and within two stomas via an elongate member. The method generally comprises using the medical system to create an anastomosis between the stomach and the jejunum.

19. A method of forming an anastomosis, the method comprising the steps of:
-
creating a stoma in a first bodily wall; creating a stoma in a second bodily wall; providing a medical system comprising an apparatus that comprises a first base and a second base with a first and second clamp member attached to the bases, the clamp members having proximal portions and distal portions that are rotatably attached to the bases, the clamp members each having a deployed state wherein the proximal portion of the first clamp member is about parallel to the distal portion of the first clamp member and the proximal portion of the second clamp member is about parallel to the distal portion of the second clamp member, the clamp members each having a delivery state wherein the proximal portion and the distal portion of the first clamp member rotate longitudinally away from each other and the proximal portion and the distal portion of the second clamp member rotate longitudinally away from each other, and the bases adapted to fit over an elongate member; inserting the apparatus into a bodily lumen; positioning the distal portions of the first and second clamp members through the stoma in the second bodily wall so that the distal portions are on the distal side of the second bodily wall; rotating the distal portions of the clamp members from the delivery state to the deployed state wherein the distal portions of the clamp members rotate laterally away from each other to press against an interior surface of the second bodily wall; rotating the proximal portions of the clamp members from the delivery state to the deployed state wherein the proximal portions of the clamp members rotate laterally away from each other to press against an interior surface of the first bodily wall; compressing the first and second bodily walls together and holding them proximate to each other after the clamp members have been rotated to the deployed state; and
,after compressing the first and second bodily walls together, simultaneously cutting the tissue of the first and second bodily walls to enlarge the size of the stomas. - View Dependent Claims (20, 21, 22, 23)
