摘要： A patch and sensor assembly for use in an EP mapping system has two portions: a reusable portion and a disposable portion. The reusable portion houses the biosensors used in magnetic based location and mapping systems and the electrical lead necessary to communicate between the biosensor and the mapping system. The reusable portion may also contain a portion of the electrode necessary to receive electrical signals from the body of the patient. The disposable portion of the patch and sensor assembly contains an adhesive covered flexible patch having at least a portion of the electrode used to receive electrical signals from the body of the patient and may contain the electrical lead necessary to communicate such an electrical signal to the mapping system. The disposable portion contains a receptacle adapted to receive and mechanically secure the reusable portion to the disposable portion of the assembly. Such a patch and sensor assembly is useful in hybrid magnetic and impedance based location and mapping systems such as those used in electrophysiology.

摘要： A catheter for mapping and/or ablating continuous linear or circumferential lesions at the intersection of a generally flat structure, such as the left atrium, and the ostium of generally cavernous regions of the heart, including pulmonary vein and the pulmonary venous antrum, comprises a catheter body with an intermediate section that is connected to a tip assembly by a highly flexible section. The intermediate section has at its distal end a preformed section, e.g., a curve, the intermediate section being deflectable in a direction opposite to the curve. The highly flexible section presets the tip assembly at an off-axis and/or off-plane angles from the preformed section.

摘要： The present invention involves a surgical device and method of use, particularly an assembly and method incorporating a peanut or barbell shaped expandable member along the distal region of an ablation device to facilitate ablation of a circumferential region of tissue engaged by the expandable member. The ablation device assembly includes an elongate body with a proximal end portion, a distal end portion, and a longitudinal axis. A contact member is located along the distal end portion of the elongate body. The contact member has a circumferential wall and is expandable from a radially collapsed condition to a radially expanded condition. The contact member also includes a single chamber having first and second bulbous sections separated by a longitudinal mid-section, wherein the first bulbous section has a smaller outside diameter than the second bulbous section when the contact member is in the expanded condition. The ablation device also has an ablation element having an ablative energy source that is located along the distal end portion, wherein the ablation element cooperates with the contact member such that the ablative energy source emits a substantially circumferential pattern of energy through the circumferential wall.

摘要： An esophageal mapping catheter enables a physician to map the location of the esophagus so as to avoid damaging the esophagus during radio frequency (RF) ablation procedures. Information from the esophageal mapping catheter is communicated to a patient information unit, communications unit and/or electroanatomic mapping system. The electroanatomic mapping system uses the information from the esophageal mapping catheter to develop a three-dimensional map of the esophagus and to monitor the temperature within the esophagus in order to prevent the creation of esophageal fistula.

摘要： The present invention relates to a tissue ablation device having a plurality of transducer elements that can be operated out of phase to orient the acoustical energy beam forward or backward in the longitudinal direction. The transducer elements may also be driven by a signal that has a common frequency, but where each element has a phase that is chosen to provide an acoustic energy beam that has an additive effect at a predetermined distance from the transducers. The transducers include a cylindrical inner electrode, a cylindrical piezoelectric material disposed over the inner electrode, and a cylindrical outer electrode disposed over the cylindrical piezoelectric material. In one embodiment, circumferential grooves are cut through at least the outer electrode separating the transducer into a plurality of functionally discrete serially arranged transducer segments. The transducer segments can be operated independent from one another.
