Abstract
Transluminal access system includes a stent delivery catheter having a handle control mechanism. The catheter comprises a number of components for establishing an initial penetration between adjacent body lumens and subsequently implanting a stent or other luminal anchor therebetween. Manipulation of the stent components is achieved using control mechanisms on the handle while the handle is attached to an endoscope which provides access to a first body lumen.

31. A method of draining a second body site to a first body site comprising:
-
advancing an endoscope to a location on a wall of the first body site; creating a lumen in the first and second body sites; advancing a deployment assembly through the endoscope and into the lumen, the deployment assembly including a shaft, a self-expanding drainage device carried on the shaft, and a sheath constraining the drainage device; moving the sheath relative to the shaft a distance sufficient to release a distal flange of the drainage device within the second body site; withdrawing the shaft, drainage device and sheath back together in the proximal direction to engage the distal flange and the second body site in closer apposition with the first body site; and moving the sheath relative to the shaft to release a proximal flange of the drainage device against the wall of the first body site. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A method for delivering a drainage stent to a target site, the method comprising:
-
penetrating adjacent tissue layers of a first body lumen and a second body at the target site; advancing a catheter assembly to the target site, the catheter assembly including a shaft, a sheath slidably disposed over the shaft, and the drainage stent constrained between the shaft and the sheath; inserting a portion of the catheter assembly into the second body; moving the sheath relative to the shaft a distance that is less than a length of the drainage stent, such that a portion of the drainage stent becomes unconstrained to deploy a distal flange of the stent in the second body; drawing the catheter assembly proximally, with the sheath maintained at the distance, to engage the distal flange with the tissue layer of the second body; and moving the sheath relative to the shaft, such that the remaining portion of the drainage stent becomes unconstrained to deploy a proximal flange of the stent in the first body lumen, whereby the adjacent tissue layers are apposed between the distal and proximal flanges. - View Dependent Claims (47, 48, 49, 50)
