Claim Text:
1. A system for occluding a body lumen, comprising: an elongate delivery device configured for insertion into a body lumen; and a tissue engaging device configured for insertion within a body lumen using the elongate delivery device, the tissue engaging device including a distal element slidably coupled with a proximal element, the distal element having a proximally extending shaft that mates with a locking mechanism of the proximal element, a proximal facing outer surface of the distal element, a distal facing outer surface of the proximal element, and an outer surface of the distal element shaft collectively defining an annular recess for receiving wall tissue of a body lumen in which the tissue engaging device has been inserted, the annular recess having an axial length determined by a relative position of the distal element to the proximal element, the distal element shaft comprising a vacuum port disposed on an outer surface thereof, the vacuum port in fluid communication with a vacuum supply lumen extending through the elongate delivery device, such that a vacuum source placed in fluid communication with the vacuum supply lumen when the tissue engaging device is inserted in a body lumen would cause plicated wall tissue of the body lumen to be drawn against the outer surface of the distal element shaft within the annular recess, and wherein movement of the distal element towards the proximal element to thereby shorten the axial length of the annular recess would apply compression to plicated wall tissue drawn into the annular recess to thereby form an occlusion of the body lumen.
