A device, system and method for diagnosing and treating gastric disorders is provided. A submucosal gastric implant device is placed within the submucosal layer of a patient's stomach wall. The device in one embodiment provides electrical stimulation of the stomach wall and may use multiple electrode pairs for sequential stimulation. The device may also have other functional aspects such as a sensor for sensing various parameters of the stomach or stomach environment, or a therapeutic delivery device. The implant may be programmed to respond to sensed information or signals. The device may be modular with a portion of the device accessible outside the stomach wall for removal and replacement. An endoscopic delivery system prepares and delivers the functional device through the esophagus and into the stomach where it is placed through an opening in the mucosa into the submucosal layer of the stomach wall. The endoscopic instruments may be used to prepare a cavity in the submucosal layer of the stomach wall and deliver the device to the prepared cavity and if appropriate close the opening in the mucosa.

Submucosal gastric implant device and method

A device and method for mapping, diagnosing and treating the intestinal tract is provided using a capsule passing through the intestinal tract. Further, a capsule tracking system is provided for tracking a capsule's location along the length of an intestinal tract as various treatment and/or sensing modalities are employed. In one variation, an acoustic signal is used to determine the location of the capsule. A map of sensed information may be derived from the pass of a capsule. Capsules may be subsequently passed through to treat the intestinal tract at a determined location along its length. One variation uses an electrical stimulation capsule to treat and/or diagnose a condition in the intestinal tract.

System for marking a location for treatment within the gastrointestinal tract

A device, system and method for diagnosing and treating a patient is provided where a functional device is attached to a stomach wall. The device in one embodiment provides electrical stimulation of the stomach wall. The device may also have other functional aspects such as a sensor for sensing various parameters of the stomach or stomach environment, or a substance delivery device. The implant may be programmed to respond to sensed information or signals. The device may be modular with a portion of the device accessible for removal and replacement. In one embodiment, an endoscopic delivery system delivers the functional device through the esophagus and into the stomach where it is attached the stomach wall with the assistance of a suction used to stabilize the tissue of the stomach wall. The device includes a chamber for receiving tissue of the stomach wall for attachment where a vacuum pressure is applied through the chamber to draw the tissue into the chamber.

The present invention provides ultrasound-guided ablation catheters and methods for their use. In one embodiment, a tissue ablation apparatus ( ) includes a flexible elongate body ( ) having proximal ( ) and distal ( ) ends. A plurality of spaced-apart electrodes ( ) are operably attached to the flexible body near the distal end. A plurality of transducer elements ( ) are disposed between at least some of the electrodes. Transducers assist the physician in determining whether or not the ablation elements are in contact with the tissue to be ablated.

Ultrasound-guided ablation catheter and methods of use

A catheter for ablating and imaging tissue includes a porous electrode structure comprising an interior region for receiving a conductive medium, an elongate tube having a distal tube end that extends within the interior region, and an ultrasonic transducer assembly housed within the distal tube end.

Ablation and imaging catheter

A catheter tube carries an imaging element for visualizing tissue. The catheter tube also carries a support structure, which extends beyond the imaging element for contacting surrounding tissue away from the imaging elements, the imaging element being movable with the support structure. The support element stabilizes the imaging element, while the imaging element visualizes tissue in the interior body region. The support structure also carries a diagnostic or therapeutic component to contact surrounding tissue.

Systems and methods for visualizing tissue during diagnostic or therapeutic procedures

The present invention provides ultrasound-guided ablation catheters and methods for their use. In one embodiment, a tissue ablation apparatus (,) includes a flexible elongate body (,) having proximal (,) and distal (,) ends. A plurality of spaced-apart electrodes (,) are operably attached to the flexible body near the distal end. A plurality of transducer elements (,) are disposed between at least some of the electrodes. Transducers assist the physician in determining whether or not the ablation elements are in contact with the tissue to be ablated.

The present invention relates to a combination device comprising two catheters, or a dual catheter assembly, for use in vascular procedures wherein the shaft of the first catheter functions as a guidewire for the second catheter. The dual catheter assembly comprises a first balloon catheter and a second balloon catheter wherein the second balloon catheter is slidably disposed on the shaft of the first balloon. In preferred embodiments, the first catheter is a low profile balloon on a wire catheter and the second catheter is a full size balloon catheter having a plurality of balloons mounted thereon. Optionally, a stent is carried by at least one of the balloons on the second catheter. In more preferred embodiments, the second catheter includes a manifold that may be used to inflate and deflate any combination of the plurality of balloons via a single port. The dual catheter assembly of the present invention is especially useful in vascular procedures such as angioplasty, progressive/multiple angioplasty, and stent delivery.

Dual catheter assembly

The present invention relates to a multiple valve single port manifold for use with a multiple lumen catheter. The inventive manifolds comprise a conduit with an entry port; a plurality of means for connecting the conduit to a plurality of catheter lumens, such that each lumen is capable of being in fluid communication with the entry port; and a plurality of means for controlling access from the conduit to the plurality of catheter lumens, such that each controlling means independently regulates access from the conduit to its corresponding catheter lumen. Because each catheter lumen is independently accessible from the same manifold port, the inventive devices are useful in any medical context where a need exists to independently control access to spatially proximal sites within a patient's passageway. For example, practice of the present invention allows a fluid to be delivered to any combination of spatially proximal vessel sites, or more typically, allows multiple balloons mounted on a catheter to be independently inflated and/or deflated during angioplasty procedures.
