The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment. The invention further discloses a catheter with a transparent occlusion element at its tip that enables examination of the lung passageway through a viewing scope.

Devices, methods, and systems for treating Type-2 Diabetes and/or obesity by facilitating the delivery of under-digested nutrients within the gastro-intestinal tract without substantial tissue removal are disclosed. In one aspect, the gastro-intestinal tract of a patient is modified by a gastro-intestinal treatment device comprising an elongate element configured to extend within the gastro-intestinal tract, a first attachment element and a second attachment element disposed on the elongate element, wherein the first attachment element and the second attachment element are configured to attach to the gastro-intestinal tract such that a portion of the gastro-intestinal tract is compressed between the first and the second attachment elements. The length of the gastro-intestinal tract modified by the device is effectively shortened, and its surface area is reduced.

Gastro-intestinal compression device

The system () includes a catheter drive unit () and a catheter () extending therefrom movably mounted to a catheter drive sled (). The catheter drive unit rotates and translates the catheter core () within the catheter sheath (). The sled has a serrated, conical drive unit interface (), with a bag-piercing tip () mateable with a translator drive output () so that a sterile drape () enclosing the catheter drive unit is automatically pierced when the catheter drive unit is mounted to the sled. A control unit () is spaced apart from the catheter drive unit and provides power and commands to the catheter drive unit and receives information and data from the catheter drive unit. The rotator and translator drive motors () are operated from both the control unit and the catheter drive unit. Both the control unit and catheter drive unit have translation displacement displays ().

Driveable catheter systems and methods

The present invention provides ultrasound imaging catheters, systems and methods for their use which will be particularly useful to monitor the positioning of ablation catheters. In one embodiment, an imaging catheter () includes a catheter body () having a distal end (), a proximal end () and a longitudinal axis (). A transducer () is rotatably coupled to the distal end. The transducer has an axis of rotation () that is at a non-zero angle relative to the catheter body longitudinal axis. Such a configuration provides an exemplary side-looking imaging catheter.

Systems and methods for positioning a first guidewire ( ) in a primary vessel (M) and a second guidewire ( ) in a branch vessel (B). One embodiment comprises an introducer ( ) having first ( ) and second lumens ( ) adapted to slidably receive the first guidewire within the first lumen and the second guidewire within the second lumen. One method embodiment includes inserting the first guidewire into the main vessel, introducing the introducer over the first guidewire, and inserting the second guidewire within the second lumen such that the second guidewire extends into the branch vessel. The introducer is withdrawn while maintaining the first and second guidewires in the respective vessels.
