Abstract: A system for delivering an endolumenal device through an endoscope includes a delivery tool and an adaptor. The delivery tool has an elongate tube configured to hold a portion of the endolumenal device therein and a first connecting feature on a distal end of the elongate tube. The adaptor is configured to attach to a handle of the endoscope. The adaptor includes a channel therethrough and a second connecting feature configured to mate with the first connecting feature of the delivery tool. The elongate tube of the delivery tool is configured to align with the channel of the adaptor when the first and second connecting features are mated.

Abstract: Aspects of a sheath are disclosed herein including a radially expandable outer cylinder and including a plurality of sheath fins distributed circumferentially about the inner surface of the central lumen of the sheath. Each of the fins extends along a length of the inner surface of the sheath and when the sheath not expanded, the form a continuous inner surface of the sheath lumen. Aspects also include a sheath that includes a radially expandable cylindrical outer layer a stiff inner member, an inner liner layer coupled to the inner surface of the stiff inner member; and an outer liner layer disposed between an outer surface of the stiff inner member and an inner surface of the outer layer.

Abstract: A device for implantation in a body may include a body defining a lumen. The body may have a first end and a second end, and the lumen may define a central axis. The body may include a first flexible flange having a first base portion and a first angled portion. The first base portion may be about perpendicular to the central axis and extend radially away from the first end. The body may further include a second flexible flange having a second base portion and a second angled portion. The second base portion may be about perpendicular to the central axis and extend radially away from the second end. The first and second angle portions may be generally angled toward each other. A loading device may be configured to load the device into a delivery device. The delivery device may be configured to delivery and deploy the device.
