Multiple electrodes are coupled together in monopolar or bipolar arrays to form lesion patterns in tissue regions at or near a sphincter. A controller couples the electrodes to a generator so that a single power channel serves more than a single electrode.

A device for treating a tissue region is supplied with a separate usage key card. The usage key card comprises a storage medium, which is formatted to contain an identification code unique to the usage key card. The usage key card is adapted to be read by a remote reader, to download the identification code for processing by a controller for the device. Processing of the identification code by the controller either enables or disables operation of the device according to prescribed criteria.

Systems and methods deploy an electrode structure in contact with the tissue region. The electrode structure carries a sensor at a known location on the electrode structure to monitor an operating condition. The systems and methods provide an interface, which generate an idealized image of the electrode structure and an indicator image to represent the monitored operating condition in a spatial position on the idealized image corresponding to the location of the sensor on the electrode structure. The interface displays a view image comprising the idealized image and indicator image. The systems and methods cause the electrode structure to apply energy to heat the tissue region while the view image is displayed on the display screen.

A deflectable guiding catheter generally having an elongated shaft with a deflectable distal section, a second lumen, a first lumen in fluid communication with a port in the distal end of the shaft, an elongated tapered deflection line within the second lumen, and reinforcement strands within a wall of the shaft. The first lumen is independent from the second lumen, and is therefore not obstructed by the deflection line. The longitudinal axes of the second lumen and first lumen are axially aligned with respect to one another, and are eccentric to the shaft longitudinal axis. The reinforcement strands and the deflection line extend in at least a portion of the deflectable distal shaft section to a location spaced proximally of the distal end of the deflectable distal shaft section.

An apparatus treats tissue at or near a sphincter. The apparatus has an elongated member having at least one lumen including an inflation lumen, and a basket assembly including a first and a second arm. An inflatable member is coupled to the inflation lumen and has a deployed and a non-deployed state. In the deployed state, the inflatable member expands the basket assembly into contact with tissue. At least one of the first and second arms of the basket assembly has a fluid lumen having an aperture for conveying a fluid from the basket assembly. A source of fluid is coupled to the fluid lumen for conveyance of fluid through the aperture. The fluid can be, e.g., an electrolytic solution, and/or an anti-infection agent, and/or an echogenic media, and/or a steroid, and/or an anesthetic, and/or a medicament, and/or a tissue cooling agent. The source can be a drug delivery device.

Systems for treating a mucosal surface of an alimentary canal tissue region are provided. The systems can include an elongate support structure, an expandable member positionable at a distal portion of the support structure and one or more radio frequency (RF) ablation electrodes carried by the expandable member. The elongate support structure and the expandable member can be adapted to place the one or more electrodes in contact with a mucosal surface of an alimentary canal tissue region. The system can further include an RF energy source connected to the one or more electrodes.

235385, 235487

A system comprising a storage medium associated with a device for treating a tissue region, the device including a handle, a catheter tube extending from the handle, a temperature sensor and a basket including a plurality of spines, the spines carrying an electrode for delivering treatment energy to a tissue site. The temperature sensor senses temperature near a distal end of the electrode. The basket is movable between a non-expanded low profile condition and an expanded condition and the electrode is movable from a first position to an extended position. The storage medium is formatted to contain an identification code uniquely assigned to the device for registration of the device if absence of prior use is determined.
