Patent Images
1. A gastric fastening system comprising:
- a placement cannula having a first and a second end, the placement cannula adapted to percutaneously enter a body lumen;
a secondary cannula with which the placement cannula is removably associated, the secondary cannula having an actuatable collar portion capable of axial collapse and radial expansion when actuated, the collar portion adapted for placement within the lumen to secure the secondary cannula within the lumen; and
an actuator for manipulating the collar portion from a first deactuated position to a second actuated position.

Abstract
A gastric fastening system is disclosed. The system contains a cannula for placement into a body lumen within a body. The cannula has a first end for positioning within the lumen, a collapsible region proximal to the first end for placement within the lumen, and an actuator for causing the collapsible region to collapse outwardly from the cannula so as to form a radial collar having a second diameter greater than the first diameter while foreshortening the length of the cannula. The collar secures the cannula against extraction from the lumen.

12. A gastric fastening system comprising:
-
a cannula for placement into a body lumen within a body, the cannula having a first diameter, a first end for positioning within the lumen, a collapsible region proximal to the first end for placement within the lumen, a second end for positioning external to the body, and a length defined by the distance between the first and second ends; and
an actuator for causing the collapsible region to collapse outwardly from the cannula so as to form a radial collar having a second diameter greater than the first diameter while foreshortening the length of the cannula, the collar securing the cannula against extraction from the lumen. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
