Abstract: A drainage catheter system includes an elongate tube with proximal and distal ends and a filament extending the tube that is adjustable to create a closed loop at the distal end of the tube when the filament is retracted relative to the tube. The filament is coupled to the tube such that the filament and tube are prevented from being separated in the event that the tube and filament are cut at the proximal end at the conclusion of a drainage procedure. The filament can be attached to the tube near the distal end. The filament can be attached to the tube along its length. The catheter system can also include a retraction mechanism having a first fixed position and second fixed position, where the second fixed position retracts the filament proximally relative to the first fixed position by actuating a plunger.

Abstract: A device for providing access through a body wall of a patient to a target site includes a hollow tube having a first large diameter segment and a second small diameter segment. A first distally tapered portion joins the first segment and the second segment, and a second distally tapered portion is distal of the second segment. A first lumen extends through the tube, and a second lumen extends from a proximal portion of the tube to the second segment. A needle received in the first lumen is deployable for piercing the body wall. A port is provided along the second segment in communication with the second lumen, and a balloon is disposed along the second segment at the port. The balloon is inflatable to a diameter at least as large as the first segment diameter for dilating an opening in the body wall.

Abstract: A non-expandable endoluminal prosthesis for implantation within a body lumen may include an elongate tubular conduit. The tubular conduit may have a first end segment and a second end segment. A drainage lumen may extend longitudinally within the tubular conduit. An actuating lumen may extend longitudinally within the tubular conduit. The prosthesis may include an actuating member received within the actuating lumen. The endoluminal prosthesis may be movable between a delivery configuration in which the tubular conduit is substantially linear and a deployed configuration in which at least one of the first end segment and the second end segment includes a retaining mechanism configured to retain the prosthesis in place relative to the body lumen. The actuating member may be configured to urge the prosthesis toward the deployed configuration.
